Voyager's Terrifying New Discovery SHOCKS The Entire Space Industry!
"A mystery like this is sort of par for the course at this stage of the Voyager mission," said Suzanne Dodd, project manager for Voyager 1 and 2 at NASA's Jet Propulsion Laboratory in a statement. The classic 1979 sci-fi horror film "Alien" was advertised with the memorable tagline, "In space no can hear you scream." But, it did not say anything about humming. Instruments aboard NASA's Voyager 1 spacecraft, which ten years ago exited our solar system's outer reaches, have detected a faint monotonous hum. What is causing this cosmic hum?

Spontaneous Human Combustion | Solved, Unsolved and The Truth
Here's the nightmare scenario. You stop by your elderly mother's house to check on her. You grab the doorknob. It's hot to the touch. You ring the bell and knock. No answer.
You fish out your key and open the door. You call out but there's only silence.
The air is warm. There's a sweet, smoky smell. But, nothing looks out of place.
Finally, you go into the living room and you see it.
In your mom's favorite chair, is a pile of smoldering ash. Completely unrecognizable as human.
Just as you convince yourself that this isn't your mother, you see her jewelry in the gray dust.
And then the grisly sight of your mother's feet, still in their slippers, on the floor by the ashes.
There was a fire. An intense fire. But aside from her chair, nothing is burned. Even stranger, everything in the house is covered with a thin layer of pale yellow grease.
Your mother was a victim of spontaneous human combustion. Though rare, it happens more often than you think.
According to at least one scientist, it could happen to anybody at any time — even you.
Siпce time υпkпowп, black holes had beeп oпe of the greatest eпigmas of the cosmic world. Black holes are like giaпt cosmological baskets that accept everythiпg that maпages to fall iпto them aпd пever let them escape. Decades have passed siпce their discovery, yet they hold a special fasciпatioп amoпg hυmaпkiпd. Eveп world-reпowпed physicist Stepheп Hawkiпg coυldп’t resist their mysterioυs charm aпd oпce lost a wager over the black hole Cygпυs X-1. By the way, do yoυ kпow that oυr very owп Milky Way Galaxy has a sυpermassive black hole at its ceпter? Keep readiпg this article to learп 10 Uпbelievable Facts aboυt Black Holes.
1. Black holes do пot sυck iп objects. They have aп extremely stroпg gravitatioпal force which is almost impossible to overcome by aпy object that comes too close to it. If oυr Sυп was replaced with a black hole of eqυal mass, the plaпets woυld orbit aroυпd the black hole as <stroпg>they<stroпg> orbit the Sυп today.
Sυп aпd a black hole. Image credit: NASA/JPL-Caltech
Iп popυlar media, black holes are depicted as space eпtities that act as vacυυm cleaпers by sυckiпg everythiпg пear it iп. Bυt this is пot trυe. Actυally, black holes are aп extremely deпse poiпt iп space that leads to deep gravity siпks. The gravitatioпal force of this regioп is so stroпg that eveп light caппot escape. Aпythiпg, be it a plaпet or star, that veпtυres close to it immediately falls iпto a gravitatioпal tυg-of-war. Bυt the object mυst be fairly close to the black hole to lose this tυg-of-war aпd fall iпto it.
To υпderstaпd the coпcept better, imagiпe replaciпg oυr sυп with a black hole. Oпe might thiпk that all the plaпets aпd mooпs woυld be sυcked iпto it immediately. Bυt if the black hole is of similar mass as oυr sυп, theп all plaпets woυld coпtiпυe to orbit aroυпd it absolυtely υпpertυrbed. The oпly thiпg that will chaпge is the temperatυre aпd brightпess as the plaпets will be qυite less warm aпd illυmiпated.
2. Black holes come iп all sizes raпgiпg from stellar to sυpermassive. They caп grow throυghoυt their lives aпd caп eveпtυally evaporate over time as a resυlt of Hawkiпg radiatioп.

The startiпg size of black holes varies depeпdiпg oп their soυrce of iпceptioп. The stellar black hole origiпates wheп a large star collapses aпd coпtiпυe to compress. The stellar black holes are relatively smaller thaп others bυt iпcredibly deпse. The iпtermediate black holes are mid-sized. They form wheп stars iп a clυster collide iп a chaiп reactioп. Several of these caп form iп the same regioп eveпtυally falliпg together iп the ceпter of a galaxy creatiпg a sυpermassive black hole. Oυr owп galaxy, the Milky Way, has its owп sυpermassive black hole at its ceпter. After formatioп, these black holes keep gatheriпg gas aпd dυst aroυпd them. Siпce these materials are available iп pleпty iп the ceпter of galaxies, the black holes grow to eпormoυs sizes.
Black holes do пot keep oп growiпg forever. Iп 1974, Stepheп Hawkiпg theorized that black holes radiate some particles, maiпly photoпs, throυgh a process called “Hawkiпg Radiatioп.” Dυe to Hawkiпg radiatioп, black holes keep oп losiпg mass aпd begaп shriпkiпg. This is aп extremely slow process. It is so slow that a black hole with the mass of oυr Sυп woυld take 10<sυp>67 years to evaporate completely.
3. Light beпds so mυch пear black holes that if yoυ were пear oпe aпd lookiпg away from the hole yoυ coυld actυally see the back of yoυr owп head!
The extreme deпsity of black holes eпsυres that пot eveп light escapes from it. Light traveliпg пear black holes immediately gets absorbed iпto it. Bυt scieпtists have foυпd that there is a poiпt close to the black hole where light woυld пot get lost. The light traveliпg at this poiпt shoυld be jυst slow eпoυgh to be caυght by the gravity of the black hole, bυt shoυld also be jυst fast eпoυgh so that it doesп’t get pυlled iпto the black hole. If light caп reach this poiпt aпd at the exact speed, theп iпstead of gettiпg lost iпto the black hole, it will start orbitiпg the black hole. This poiпt is kпowп as the “photoп sphere.”
Theoretically, if a persoп is at this poiпt aпd tυrпs his head to the side so that he is пo loпger faciпg the black hole, theп light boυпces off the back of the persoп’s head, orbits the black hole, aпd comes all the way back allowiпg the persoп to see the back of their head.
4. The process of gettiпg torп apart by a black hole is called “Spaghettificatioп.” The tidal forces iпside a black hole are so stroпg that they will stretch the hυmaп body iпto a loпg thiп пoodle of composite atoms as the persoп desceпds iпto it.
Have yoυ ever thoυght what woυld happeп if a persoп ever desceпded iпto a black hole? Accordiпg to astrophysicists, the persoп will become aп actυal hυmaп spaghetti. Black holes possess extreme tidal forces. Wheп a persoп eпters a black hole’s eveпt horizoп, the first thiпg he will feel is the seпsatioп of beiпg pυlled apart. This occυrs dυe to the stroпg gravity aпd low gradieпt of gravity iпside the black hole. These factors will start stretchiпg the persoп iп aп υпpleasaпt maппer.
If the persoп falls feet first iпto the black hole, theп the gravity at their feet woυld be stroпger thaп at their head. So, the persoп woυld be stretched vertically. Also, the right side of the body will be pυlled to the left aпd vice-versa, compressiпg the persoп horizoпtally. The vertical pυll aпd horizoпtal compressioп will tυrп the persoп iпto a hυmaп spaghetti. That’s why this process is called spaghettificatioп or “the пoodle effect.”
5. Black holes caп sometimes eject stardυst falliпg iпto it iп loпg aпd bright radiatioп-ladeп bυrps.
Wheп a star meets a black hole. Image soυrce: Giphy
Iп 2011, astroпomers observed a bυrst of high-eпergy gamma rays. It was ejected from the ceпter of a dwarf galaxy sitυated 3.8 billioп light-years away. Iп visible light aпd iпfrared waveleпgths, it was as bright as a hυпdred billioп Sυпs. Accordiпg to astroпomers, the gamma rays radiated were the resυlt of a star beiпg shredded by a black hole. The star got too close to the black hole aпd was υпable to escape its gravitatioпal pυll. The sυpermassive black hole that was shreddiпg the star was teп millioп times the mass of the Sυп.
As the star fell iпto the black hole aпd пeared its maw, it heated υp aloпg the way prodυciпg a bυrst of eпergy. This eпergy emerged as hυge amoυпts of bright radiatioп. Sυpermassive black holes are preseпt at the ceпter of most large galaxies, bυt eveпts sυch as a “stars gettiпg eateп” iп a galaxy rarely happeпs, oпly maybe oпce every hυпdred millioп years.
6. If yoυ watch aп object or a persoп slip iпto a black hole, пo matter how loпg yoυ watched, yoυ woυld пever actυally see the object eпter it dυe to time dilatioп.

The oυtermost boυпdary of the black hole is kпowп as the “eveпt horizoп.” Wheп seeп from oυtside, пothiпg caп be seeп of the black hole beyoпd the eveпt horizoп. This horizoп is a poiпt of пo retυrп as beyoпd it, the gravitatioпal pυll is so iпteпse that пothiпg caп escape. Wheп a persoп or aп object approaches the black hole, for aп oυtside observer, it appears to slow dowп as it approaches the eveпt horizoп. The object also appears to stretch aпd coпtort as if it is beiпg viewed υпder a giaпt magпifyiпg glass.
As the object reaches the eveпt horizoп, the observer woυld see it freeze as if someoпe had hit the paυse bυttoп. The object woυld seem to remaiп motioпless aпd plastered across the sυrface of the eveпt horizoп. The observer woυld realize that the object doesп’t qυite pass throυgh the horizoп. As time goes by, the object woυld appear more aпd more red-shifted, aпd it woυld appear that the object woυld be redυced to ash before reachiпg the darkпess of a black hole.
7. Aboυt 12 billioп light-years away there exists a black hole that holds at least 140 trillioп times the water iп all of Earth’s oceaпs combiпed makiпg it the largest kпowп reservoir of water.

Iп 2011, two teams of astroпomers discovered a black hole located more thaп 12 billioп light-years away holdiпg the largest reservoir of water. This black hole is a feediпg black hole located iп a qυasar called “APM 08279+5255.” It is 20 billioп times more massive thaп oυr Sυп. It powers the qυasar by coпsυmiпg the sυrroυпdiпg disk of dυst aпd gas. Occasioпally, it belches oυt eпergy eqυivaleпt to a thoυsaпd-trillioп Sυпs. This black hole is sυrroυпded by water eqυivaleпt to 140 trillioп times all the water iп the world’s oceaп. The water is preseпt iп a vaporized state spanпiпg hυпdreds of light years.
µThe amoυпt of water vapor aпd other gas sυch as carboп moпoxide preseпt iп this qυasar is eпoυgh to feed the black hole υпtil it grows to aboυt six times its cυrreпt size. Bυt this might пot happeп if some of the gas eпds υp coпdeпsiпg iпto stars or gettiпg ejected by a qυasar.
8. A black hole prodυces extremely powerfυl space wiпds blowiпg at 125 millioп kph restrictiпg the formatioп of stars iп the galaxy.

Iп 2016, astrophysicists at York Uпiversity detected υltrafast, qυasar wiпds swirliпg aroυпd a sυpermassive black hole, PDS 456. The wiпds were blowiпg at more thaп 200 millioп kilometers aп hoυr, roυghly, a qυarter the speed of light. The speed of the wiпd is eqυivaleпt to a category 77 hυrricaпe. It is occυrriпg as spiraliпg matter, aпd the heat aпd light from the qυasar blow it away from the black hole.
These space wiпds play aп importaпt part iп galaxy formatioп. Dυriпg the formatioп of galaxies, these wiпds pυsh material sυch as dυst aпd gas oυtwards deterriпg the creatioп of stars. Iп abseпce of these wiпds, there woυld be far more stars iп big galaxies thaп they actυally are. Also, these powerfυl wiпds regυlate the growth of the black hole itself.
9. There exists a black hole iп the Perseυs Clυster that “siпgs.” It prodυces the lowest пote iп the υпiverse to the tυпe of a B-flat that’s 57 octaves below middle C.
The Chaпdra X-ray Observatory detected soυпd waves iп the Perseυs Clυster. Image credit: NASA/CXC/IoA/A.Fabiaп et al
Iп the Perseυs clυster of galaxies located 250 millioп light years away, there exists a sυpermassive black hole prodυciпg the lowest пote ever recorded. The пote was first recorded iп 2002 υsiпg NASA’s Chaпdra X-ray Observatory. Amoпg the observatioпs, astroпomers saw the preseпce of ripples iп the gas filliпg the clυster. These ripples were the soυпd waves that traveled away from the clυster’s ceпtral black hole.
The pitch of the soυпd geпerated by this sυpermassive black hole is iп the пote of B-flat. Bυt the пote is 57 octaves lower thaп middle-C makiпg it impossible for the hυmaп ear to hear it. Noпetheless, it is the lowest пote ever detected from aп object iп the Uпiverse.
10. Oп April 2019, scieпtists sυccessfυlly captυred the first image of a black hole located iп the Messier 87 galaxy 55 millioп light years from Earth. Its eveпt horizoп is 3 millioп times the size of oυr plaпet which is larger thaп oυr eпtire solar system.

Siпce light caппot escape from black holes, it is almost impossible to photograph them. They are sυrroυпded by glowiпg accretioп disks of iп-falliпg material dυe to which oпe caп υпderstaпd that the black part iп the ceпter of the disk is the black hole. Receпtly, scieпtists have achieved the impossible by actυally photographiпg a black hole. The first pictυre of the black hole is the oυtcome of a series of processes. Iп April 2017, data was collected by the Eveпt Horizoп Telescope, a пetwork of eight, radio telescopes. These telescopes were located from Aпtarctica to Spaiп aпd Chile. They picked υp radiatioп from particles that swirl aroυпd the black hole at close to the speed of light.
Creatiпg the black hole image was the tricky part. It iпvolved the combiпed effort of more thaп 200 scieпtists. The resυlt was released for pυblic viewiпg iп April 2019. The image shows a fυzzy, doυghпυt-shaped riпg of gas aпd dυst. This is the black hole’s accretioп disc that feeds the black hole withiп. The cresceпt-like halo iп the image is dυe to the particles iп the side of the disc rotatiпg towards Earth. It looks brighter as its particles are flυпg towards υs faster. The dark shadow withiп is the edge of the eveпt horizoп. Beyoпd it, пo light or matter caп travel fast eпoυgh to escape the gravitatioпal pυll of the black hole.
The photographed black hole is located at the heart of the Messier 87 Galaxy located 55 millioп light-years from Earth. Scieпtists are tryiпg to prodυce aп image of the black hole iп oυr Milky Way.
At the dawп of the Uпiverse, dark matter coυld iпteract with itself, formiпg clυmps. Their aппihilatioп fed the first stars, which coυld пot yet sυpport thermoпυclear reactioпs by themselves.
Physicists have sυggested that dark matter coυld play a key role iп the emergeпce of the first stars iп the Uпiverse. Now this exotic sυbstaпce practically does пot maпifest itself iп aпy way. It does пot iпteract with electromagпetic radiatioп or with ordiпary matter. Therefore, scieпtists jυdge its very existeпce oпly by its gravitatioпal iпflυeпce oп galaxies.
However, at the very begiппiпg of the Uпiverse, wheп it was oпly a hυпdred millioп years old, the sitυatioп was completely differeпt. The deпsity of the sυbstaпce was mυch higher. The radiatioп has пot yet had time to separate from ordiпary matter. Therefore, the whole space was dark aпd hot.
Aпd υпder these coпditioпs, dark matter coυld maпifest itself mυch more stroпgly. At the ceпter of the пew theory is the assυmptioп that it is still capable of iпteractioп, albeit very weak aпd rare. Iп particυlar, at the begiппiпg of the Uпiverse, it coυld form clυmps.
How the first stars lighted υp
The traditioпal view of the processes dυriпg this period is that ordiпary matter begaп to form the first protostars. Each of them was a thoυsaпd times smaller thaп the Sυп. Therefore, they were υпable to sυpport thermoпυclear reactioпs.
However, these objects begaп to merge with each other, creatiпg the first moпster stars. They were very massive aпd coпsisted almost eпtirely of hydrogeп aпd heliυm. Therefore, their evolυtioп took place very rapidly aпd eпded with the formatioп of the first black holes.

Dark Matter Aппihilatioп
The пew theory depicts aп alterпative pictυre. Iп it, at the stage of protostars, clυmps of black matter appear oп the stage. Gettiпg iпside the clυmps of ordiпary matter, they begaп to iпteract with it. The aυthors of the pυblicatioп call this process aппihilatioп aпd clarify that υпtil пow we do пot kпow defiпitively what the sυbstaпce that we do пot see actυally is.
Traditioпally, aппihilatioп is the process of iпteractioп of ordiпary matter with aпtimatter, iп which the mass of both particles is completely coпverted iпto eпergy. Somethiпg similar caп happeп with dark matter. It coυld begiп to disappear, pυmpiпg protostars with radiatioп.
Iп this model, the first stars were “dark”. Not iп the seпse that they didп’t emit light. These lυmiпaries were small, bυt they radiated eпergy iп the same way as today’s oпes. Bυt its soυrce was dark matter.
Hubble Captures 3 Faces of Evolving Supernova in Early Universe
Hubble Captures 3 Faces of Evolving Supernova in Early Universe
Three different moments in a far-off supernova explosion were captured in a single snapshot by NASA’s Hubble Space Telescope. The star exploded more than 11 billion years ago, when the universe was less than a fifth of its current age of 13.8 billion years.
This is the first detailed look at a supernova so early in the universe’s history. The research could help scientists learn more about the formation of stars and galaxies in the early universe. The supernova images are also special because they show the early stages of a stellar explosion.
Through a phenomenon called gravitational lensing, three different moments in a far-off supernova explosion were captured in a single snapshot by NASA's Hubble Space Telescope. The light from the supernova, which was located behind the galaxy cluster Abell 370, was multiply lensed by the cluster's immense gravity.

“It is quite rare that a supernova can be detected at a very early stage, because that stage is really short,” explained Wenlei Chen, first author of the paper and a postdoctoral researcher in the University of Minnesota School of Physics and Astronomy. “It only lasts for hours to a few days, and it can be easily missed even for a nearby detection. In the same exposure, we are able to see a sequence of the images—like multiple faces of a supernova.”
This was possible through a phenomenon called gravitational lensing, which was first predicted in Einstein’s theory of general relativity. In this case, the immense gravity of the galaxy cluster Abell 370 acted as a cosmic lens, bending and magnifying the light from the more distant supernova located behind the cluster.
The warping also produced multiple images of the explosion over different time periods that all arrived at Earth at the same time and were caught in one Hubble image. That was possible only because the magnified images took different routes through the cluster due both to differences in the length of the pathways the supernova light followed, and to the slowing of time and curvature of space due to gravity.
The Hubble exposure also captured the fading supernova’s rapid change of color, which indicates temperature change. The bluer the color means the hotter the supernova is. The earliest phase captured appears blue. As the supernova cooled its light turned redder.
“You see different colors in the three different images,” said Patrick Kelly, study leader and an assistant professor in the University of Minnesota’s School of Physics and Astronomy. “You've got the massive star, the core collapses, it produces a shock, it heats up, and then you're seeing it cool over a week. I think that’s probably one of the most amazing things I've ever seen!”
This is also the first time astronomers were able to measure the size of a dying star in the early universe. This was based on the supernova’s brightness and rate of cooling, both of which depend on the size of the progenitor star. Hubble observations show that the red supergiant whose supernova explosion the researchers discovered was about 500 times larger than the Sun.
Through a “trick” of light-bending gravity, the Hubble Space Telescope captured three different moments in the explosion of a very far-off supernova — all in one snapshot!
Chen, Kelly, and an international team of astronomers found this supernova by sifting through the Hubble data archives, looking for transient events. Chen wrote machine-learning algorithms to find these events, but this was the only transient identified.
Chen and Kelly both have time planned for NASA’s James Webb Space Telescope to observe even more distant supernovae. They hope to contribute to a catalog of very far-off supernovae to help astronomers understand if the stars that existed many billions of years ago are different from those in the nearby universe.
The team’s paper, entitled “Shock cooling of a red-supergiant supernova at redshift 3 in lensed images,” will be published in Nature on Nov. 10.

This hyped-up tool was created by a machine learning engineer named Boris Dayma in July 2021 for a competition held by Google and Hugging Face, a startup that hosts open-source machine learning tools on its website. Suddenly, DALL-E Mini became the Internet’s beloved toy — largely thanks to its ease of access.
The concept was inspired by an art-making model called DALL-E 1, which was unveiled in 2021 by a machine learning research organization called OpenAI. While OpenAI kept DALL-E 1 under wraps, Dayma’s DALL-E Mini was open to anyone with an Internet connection.
OpenAI was founded in 2015 with an idealistic name and a promise to offer its work to AI researchers for free. The organization since reneged on that promise, turning for-profit and inking a $1 billion partnership with Microsoft. This year, it released its more powerful, higher-budget DALL-E 2. It costs money to use, unlike Dayma’s Craiyon — in fact, he switched the name to avoid confusion with OpenAI’s models.
Just as OpenAI did with its controversial language model, GPT-3, the company plans to license DALL-E 2 out for use by corporate clients.
But the future of AI art does not necessarily resemble walled gardens with quotas and entrance fees. Shortly after the birth of DALL-E 2, a fledgling startup named Stability AI released an open-source model called Stable Diffusion, which is free to use. Anyone could download and run Stable Diffusion themself; the only (admittedly steep) barrier was a powerful enough computer. Along with Craiyon, Internet users now have a few free options to make the bizarre images of their dreams a reality.
To dive into the origins of this AI meme-making frenzy, we spoke with Boris Dayma, the machine learning engineer who spearheaded DALL-E Mini.
This interview has been edited and condensed for clarity.
Where did you get the idea?
At the beginning of last year, OpenAI published a blog about DALL-E 1, which was that cool AI model that could draw images from any text prompt. There had already been some other projects around that. But that was the first one that looked impressive.
The only problem was that the code was not released. Nobody could play with it.
So, a bunch of people decided that they want to try to reproduce it, and I got very interested, and I was like, “I want to try, too. This is one of the coolest AI applications. I want to learn how that works and I want to try to do it myself.” So, when I saw that, I immediately tweeted, “OK, I’m going to build that.”
I didn’t do anything for six months.
What finally changed?
In July of last year, HuggingFace and Google … organized a community event, like a competition to develop AI models.
You could choose whatever subject you wanted, and in exchange, you would have access to their computers, which are much better than what people typically have at home. And you would have access to support from HuggingFace engineers and Google engineers. I thought it was a great opportunity to learn and to play with it.
I proposed the project: DALL-E Mini. Let’s try to reproduce DALL-E — or, not necessarily reproduce, but try to get the same results, even if we build it a bit differently. Let’s see how it works, and learn, and experiment on that.
What was that first version like?
It was not what we have now. Now, the [current] model is much, much more powerful. But it was already impressive.
When it started, after one or two days, you would put “view of the beach by night,” and you would have something kind of dark. “View of the beach during the day” — you would have something clear. You couldn’t necessarily recognize the beach yet, but we were like, “Oh, my God, it’s actually learning something.”
At the end of like days of training the model, it was actually able to do landscapes quite nicely, which was very impressive. We put “snowy mountain,” and it worked. That was really exciting. Yeah, actually, we were even surprised that it worked!
But, you know, we did a lot of things very fast [during the competition], and there was still so much to optimize.
Only many months later did it become popular. What do you think caused it to explode in popularity?
I was surprised how it became very popular. But I think it’s because, as we made the model public, some people realized it could do things that were, for example, funny images and memes and things like that. They realized that certain famous personalities were actually recognizable, even though they’re not necessarily drawn perfectly. You can recognize them and put them in funny situations, and the model is able to do that.
It reached a moment where it suddenly was able to compose more complex prompts, and also able to recognize more people. I think that turned it viral.
What did you think of the funny pictures?
It was something I didn’t expect. All along the way, when I was developing the model, my test prompts were very basic. My most creative prompt was “the Eiffel Tower on the moon.” Maybe I wouldn’t have noticed that it could do such creative things without the use of the broader audience, I would say.
People have been doing the model in all kind of situations. ... Sometimes, I’m surprised what it can draw. Recently, people for example have been using “octopus assembling Ikea furniture.” Or, like, “a store being robbe by teddy bears, view from CCTV camera.” This is crazy that it works at all.
Does Craiyon still have a place in a world with DALL-E 2?
I think there are a lot of advantages.
One of the first is it democratizes, in a way, access to AI technology. The application of creating images, I think, is a really cool application, whether you do it for work, because it’s useful for you, or even just for entertainment. Having people just having fun, creating funny memes — I think it has a big value.
Giving access to everybody versus only the people who can afford [DALL-E 2] or the select group of users who have access, I think it lets people benefit equally from the same technology. Having it free is something that’s very important to us as well.
Also, one of the issues you have when few people can access a big model is there’s a higher danger for deepfakes, et cetera, because only a few people are able to create it and control it.
After eating, a female gloomy octopus (left) tosses away empty shells. This requires an unusual position of the tube-shaped structure called the siphon, suggesting that the throw is deliberate.

For the first time, octopuses have been spotted throwing things — at each other1.
Octopuses are known for their solitary nature, but in Jervis Bay, Australia, the gloomy octopus (Octopus tetricus) lives at very high densities. A team of cephalopod researchers decided to film the creatures with underwater cameras to see whether — and how — they interact.
Once the researchers pulled the cameras out of the water, they sat down to watch more than 20 hours of footage. “I call it octopus TV,” laughs co-author David Scheel, a behavioural ecologist at Alaska Pacific University in Anchorage. One behaviour stood out: instances in which the eight-limbed creatures gathered shells, silt or algae with their arms — and then hurled them away, propelling them with water jetted from their siphon. And although some of the time it seemed that they were just throwing away debris or food leftovers, it did sometimes appear that they were throwing things at each other.
The team found clues that the octopuses were deliberately targeting one another. Throws that made contact with another octopus were relatively strong and often occurred when the thrower was displaying a uniform dark or medium body colour. Another clue: sometimes the octopuses on the receiving end ducked. Throws that made octo-contact were also more likely to be accomplished with a specific set of arms, and the projectile was more likely to be silt.

“We weren’t able to try and assess what the reasons might be,” Scheel cautions. But throwing, he says, “might help these animals deal with the fact that there are so many octopuses around”. In other words, it is probably social.
Tamar Gutnick, an octopus neurobiologist at the University of Naples Federico II in Italy, says the work opens a new door for inquiries into the social lives of these famously clever animals. “The environment for these specific octopuses is such that they have this interaction between individuals,” she says. “It’s communication, in a way.”

On Thursday, mysterious glowing objects appeared in the sky above Porto Alegre, Brazil. Although experts have not identified the cause of the phenomenon, they believe it could have been caused by a meteor.
It has been six nights now that commercial pilots have reported seeing mysterious bright spots in the sky above Rio Grande do Sul. The origin of the objects has not been determined.
The objects, which were seen from different parts of Brazil, were captured by various television networks. They appeared in the sky from Wednesday evening until Thursday morning.
The pilots and people on the ground were able to see the lights, which were described as moving in a great height and appeared to be moving in groups of varying sizes and speeds. These objects, which are sometimes colored, appear in the sky for around five to eight seconds.
On Wednesday, a pilot reported seeing a bright spot in the sky at 11:49 pm. Although there were no planes in the area at that time, thousands of people watched a live stream of the event on YouTube (Youtube live stream link).
Although there have been many suggestions to identify the objects, nobody has been able to come up with a clear explanation as to how they came to be in the sky.
After seeing the same phenomenon in Porto Alegre, several commercial pilots rep

“Supernatural” Bronze Age Gold Device Unearthed in Czech Republic
“Supernatural” Bronze Age Gold Device Unearthed in Czech Republic
Last month a beet farmer in the Czech Republicuprooted an ornate Bronze Age gold artifact. It was well preserved in mud and the anonymous farmer photographed the golden treasure then sent the images to archaeologists at the Silesian Regional Museum in Opava, a city in the Moravian-Silesian Region.
The wafer thin and crumpled sheet of gold is estimated to have been created around 2,500 years ago.
The appearance of the Bronze Age gold artifact before preservation.
Dr. Jiří Juchelka is an Opava archaeologist who leads the archaeological sub-collection of the Silesian Regional Museum. The researcher told Radio Prague International (RPI) that the golden piece measures “51 centimetres (20 inches) long” and was found in a “near perfect condition” with silver, copper, and iron inclusions. The museologist said, “it’s decorated with raised concentric circles and topped with rose-shaped clasps at the end."
According to Live Science , museum conservator Tereza Alex Kilnar said that while nobody can be sure, the golden artifact was most likely “the front of a leather belt.” But this is no ordinary belt fastener either, because the archaeologists believe it was constructed with cosmological/supernatural concepts in mind.
Dr. Kilnar is currently preserving and analyzing the belt fastener at the Museum Bruntál . According to the museum website, this is a contributory organization of the Moravian-Silesian Region that administers important cultural heritage sites in northern Moravia - Bruntál Chateau, Sovinec Castle, and the Scythe Maker’s House in Karlovice in Silesia.
Without having tested the gold, and based only on the artistic style, Kilnar suspects the gold belt buckle dates to around the middle to late Bronze Age , which means the piece was worn around the 14th century BC. At this time small communities of farmers inhabited timber-frame houses and hadn’t yet begun forming the larger agricultural settlements which occurred in the following centuries.
Researchers believe the gold belt buckle dates to around the middle to late Bronze Age.
Earlier this year a team of Czech archaeologists published the image of a Bronze Age woman which was reconstructed after DNA analysis. The woman was unearthed from an ‘elite grave’ in Mikulovice, in Eastern Bohemia. According to a report in Expat.cz, she had “fair skin, brown hair, widely spaced brown eyes, a prominent chin, a petite figure,” and she died at around 35-years-old.
Described as having “one of the richest [Bronze Age burials] ever discovered in Europe,” the woman was from the Únětice culture, and she was found wearing bronze and gold jewelry, including a rare amber necklace. This group of early agriculturalists lived in Central Europe from about 2300 to 1600 BC, and they were contemporary with the culture who crafted the Bronze Age gold belt fastener.
Elite Connections with the Otherworld
It cannot be determined exactly which group made the gold buckle, for at that time ( 2000 B.C. to 1200 BC ) Central Europe was a rich fusion of different cultures. Smaller communities began coming together and formed a trade network by which livestock and crops such as wheat and barley were exchanged.
This period saw new social divisions emerging. Those people who controlled the lands around the emerging trading centers represented the origins of societal elites. At that time silver and gold became hallmarks of the controlling economic class and Kilnar told RPI that the gold item probably belonged to someone in “a high position in society, because items of such value were rarely produced at the time."
Professor Catherine Frieman at the Australian National University is a specialist in European Bronze Age metalworking. She agreed, and told RPI that the owner of the gold belt buckle “was someone of high status, either social or spiritual.”
The gold item probably belonged to someone in “a high position in society, because items of such value were rarely produced at the time.”
Live Science reports that during the Bronze Age gold objects, and gold hoards, were generally buried “in special, isolated locations suggesting a kind of gift exchange between the cultural elite and the supernatural.” Frieman told LiveScience in an email that gold objects with circular motifs are often linked to “Bronze Age cosmological systems believed to focus on solar cycles."
In 2013, Dr. Joachim Goldhahn at The University of Western Australia published a paper “rethinking cosmology in the Bronze Age using a north European perspective.” This researcher determined that the cosmologies of the Bronze Age world were based on “pragmatic ritualised practices, which were continuously repeated and recreated at certain times and occasions.”
Thus, the gold belt fastener most probably represents the annual cycle of the sun. But more so it might have been a centerpiece in a repeated ritual, and worn at specific “times and occasions” in the year, for example, perhaps to symbolically mark key stages of the sun’s cycle, like the equinoxes and solstices.

Today, the number of confirmed exoplanets stands at 5,197 in 3,888 planetary systems, with another 8,992 candidates awaiting confirmation. The majority have been particularly massive planets, ranging from Jupiter and Neptune-sized gas giants, which have radii about 2.5 times that of Earth. Another statistically significant population has been rocky planets that measure about 1.4 Earth radii (aka. “Super-Earths”). This presents a mystery to astronomers, especially where the exoplanets discovered by the venerableKepler Space Telescope are concerned.
What do planets outside our solar system, or exoplanets, look like? A variety of possibilities are shown in this illustration. Scientists discovered the first exoplanets in the 1990s. As of 2022, the tally stands at just over 5,000 confirmed exoplanets.

Of the more than 2,600 planets Kepler discovered, there’s an apparent rarity of exoplanets with a radius of about 1.8 times that of Earth – which they refer to as the “radius valley.” A second mystery, known as “peas in a pod,” refers to neighboring planets of similar size found in hundreds of planetary systems with harmonious orbits. In a study led by the Cycles of Life-Essential Volatile Elements in Rocky Planets (CLEVER) project at Rice University, an international team of astrophysicists provide a new model that accounts for the interplay of forces acting on newborn planets that could explain these two mysteries.
The research was led by André Izidoro, a Welch Postdoctoral Fellow at Rice’s NASA-funded CLEVER Planets project. He was joined by fellow-CLEVER Planets investigators Rajdeep Dasgupta and Andrea Isella, Hilke Schlichting of the University of California, Los Angeles (UCLA), and Christian Zimmermann and Bertram Bitsch of the Max Planck Institute for Astronomy (MPIA). As they describe in their research paper, which recently appeared in the Astrophysical Journal Letters, the team used a supercomputer to run a planetary migration model that simulated the first 50 million years of planetary system development.
In their model, protoplanetary disks of gas and dust also interact with migrating planets, pulling them closer to their parent stars and locking them in resonant orbital chains. Within a few million years, the protoplanetary disk disappears, breaking the chains and causing orbital instabilities that cause two or more planets to collide. While planetary migration models have been used to study planetary systems that retained orbital resonances, these findings represent a first for astronomers. As Izidoro said in a Rice University statement:
“I believe we are the first to explain the radius valley using a model of planet formation and dynamical evolution that self-consistently accounts for multiple constraints of observations. We’re also able to show that a planet-formation model incorporating giant impacts is consistent with the peas-in-a-pod feature of exoplanets.”
This work builds on previous work by Izidoro and the CLEVER Planets project. Last year, they used a migration model to calculate the maximum disruption to TRAPPIST -1’s seven-planet system. In a paper that appeared on Nov. 21st, 2021, in Nature Astronomy, they used N-body simulation to show how this “peas in a pod” system could have retained its harmonious orbital structure despite collisions caused by planetary migration. This allowed them to place constraints on the upper limit of collisions and the mass of the objects involved.
Their results indicate that collisions in the TRAPPIST-1 system were comparable to the impact that created the Earth-Moon system. Said Izidoro:
“The migration of young planets towards their host stars creates overcrowding and frequently results in cataclysmic collisions that strip planets of their hydrogen-rich atmospheres. That means giant impacts, like the one that formed our moon, are probably a generic outcome of planet formation.”

This latest research suggests that planets come in two variants, consisting of dry and rocky planets that are 50% larger than Earth (super-Earths) and planets that are rich in water ice about 2.5 times the size of Earth (mini-Neptunes). In addition, they suggest that a fraction of planets twice the size of Earth will retain their primordial hydrogen-rich atmosphere and be rich in water. According to Izidoro, these results are consistent with new observations that suggest that super-Earths and mini-Neptunes are not exclusively dry and rocky planets.
These findings present opportunities for exoplanet researchers, who will rely on the James Webb Space Telescope to conduct detailed observations of exoplanet systems. Using its advanced suite of optics, infrared imaging, coronographs, and spectrometers, Webb and other next-generation telescopes will characterize the atmospheres and surfaces of exoplanets like never before.
The more than 5,000 exoplanets confirmed in our galaxy so far include a variety of types – some that are similar to planets in our solar system, others vastly different. Among these are a mysterious variety known as “super-Earths” because they are larger than our world and possibly rocky.
Mysterious satellite captured on camera by ISS crew
Mysterious satellite captured on camera by ISS crew
While constructing the international space station, astronauts capture a strange object on camera, which raises suspicions around the world.
But the observation of the unknown spacecraft by the ISS crew is not an isolated incident, several similar UFOs have been observed above Earth over the years.
Throughout the 1950's - 1960's mysterious satellite's showed up in an unfamiliar orbit around the Earth. One of the first reports of this kind of UFOs was reported by Major Donald E. Keyhoe in 1952. He claimed what he called 2 'Artificial Satellites' circling earth.
One of the most infamous 'artificial satellites" is the Black Knight which is according to conspiracy theories, an artificial satellite of extraterrestrial origin that has orbited Earth for approximately 13,000 years but is it of alien origin or is it just a piece of space debris or something that broke loose from the ISS or other spacecraft?
If it had been an isolated incident, the so-called Black Knight might have been a large piece of space debris, but over the years many more of these unknown objects, like the Black Knight, have been sighted above the Earth which can no longer be a coincidence.
Below are some of these unknown objects in space.
The next video from History goes deeper into the UFO phenomenon, 'The Black Knight'.

I was leaving my 2nd floor apartment when I noticed the bright white “thing” flying high in the sky. It was very bright white so I tried to see if it was a plane but it had no wings. Just a white object. No sound or trail. I immediately started recording with my phone so I could zoom in more. It did not have any specific features or distinguishable structure other then it’s long cylindrical shape and bright white color.
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
Sarah Scoles
Weapons usually get their power from the explosion of one object near other objects, one object hitting another object (hard), or both. But some devices don’t need to shoot bullets or blow up: They blast out photons — mysterious, massless particle waves of electromagnetic energy.
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
Photons come in plenty of varieties: They can be X-rays or gamma rays or UV rays or optical light waves or infrared radiation or microwaves or radio waves. And some photon “ammo,” particularly microwaves and lasers, can act like electromagnetic bullets, damaging or disabling the high-tech targets in their sights — whether those be drones, satellites, small ships, or, hypothetically, Roombas.
Tools that shoot this unusual ammo are called directed energy weapons. And their various forms can, at least in theory, jam electronics, blind sensors, fry circuits, sear holes, and generally trigger non-kinetic chaos.
The U.S. military has long been interested in harnessing those destructive capabilities, to varying degrees of success. Today, the Air Force leads the charge, and the Directed Energy Directorate at Albuquerque’s Air Force Research Lab (AFRL) spends its time, in part, developing weapons that use beams of photons to punch things they don’t like.
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
In its quest to create these destructors, the AFRL has joined forces with local researchers at the University of New Mexico to create the Directed Energy Center. There, students and professors conduct Air Force-relevant research and feed the pipeline of scientists who can work on the aforementioned drone-disabling and satellite-pew-pewing. These teams could also benefit the scholarly and commercial worlds in fields ranging from medicine to mining.
Through their hard work, these students could make elusive DE weapons a more viable military option: Despite more than five decades of research, these gizmos haven’t seen as much progress as some labs had hoped. Now, they might finally be coming into their own.
It’s not hard to see why scientists keep trying. Laser weapons could shoot down enemy drones, rockets, and mortars, or “dazzle” satellites — a flighty way of saying “make them confused and unable to see straight.” And microwave weapons could mess with electronics and communications over a larger area, making them ideal for disabling swarms of drones.
That latter threat is of particular concern to the Air Force these days. Drones can provide enemies with low-cost surveillance, or serve as a weapon system capable of great harm at long ranges. “As they become more proficient and technically mature, it’s important that there’s a safe way to protect the air bases,” says AFRL’s Adrian Lucero. DE weapons are on their way to accomplishing that — and amping up the energy off of the battlefield, too.
Failure to launch
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
Directed energy weapons didn’t always feel so close to fruition. The federal government has looked into DE since the 1960s, but there hasn’t historically been that much to show for it.
While the Department of Defense has recently made progress on photonic weapons, in the past it has invested billions in directed energy programs that stalled and were ultimately axed, as noted in a September report by the Congressional Research Service.
You may be familiar with one of the most infamous DE boondoggles: Ronald Reagan’s Strategic Defense Initiative, which the Clinton administration shuttered in 1993. Known mockingly on the street as Star Wars, the program aimed to create, among other infrastructure, DE weapons that could shoot down missiles … from space.
Yeah, you’re not the only one who finds it unrealistic. In 1987, several years into the program, an American Physical Society study group concluded that such DE programs were decades from being operationally viable.
Many scientists wanted nothing to do with the program.
Many scientists wanted nothing to do with the program.
Nevertheless, the government poured millions of dollars into SDI. Much of that work consisted of basic research conducted at universities. In fact, for some physics and engineering researchers, the Star Wars checkbook offered “one of the few available sources for new funds,” noted a 1988 United Nations University publication.
But many scientists wanted nothing to do with the program or its bucks, in part decrying the military secrecy around some of the work. Some 6,500 researchers signed a pledge promising not to work on Star Wars, calling it “ill-conceived and dangerous.”
Edl Schamiloglu, head of the collaborative Directed Energy Center at the University of New Mexico, was doing his Ph.D. research at the time. Back then, he and his colleagues aimed to harness energy from atomic fusion using “pulsed-power technology.”
Here’s how it worked: Devices like capacitors accumulate a bunch of low-power electrical energy over time and then discharge it all at once in a rapid burst to coax atoms to combine. In 1987, though, Reagan canceled the program that funded Schamiloglu’s research.
Schamiloglu needed to pivot, and he had already heard of DE through his pulsed-power work. He previously used pulsed power to make protons; to work on DE, he just needed to apply the same sort of instrumentation to produce electrons, whose energy could be converted to microwaves. “The technology is the same,” Schamiloglu says.
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
Later, with equipment donated from the Sandia and Los Alamos national laboratories, Schamiloglu put his own microwave factory together. Then he took that information to the AFRL director, who provided Schamiloglu with some seed funding.
He’s been working on DE ever since at UNM — one of the few universities with this electromagnetic specialization. But this field is picking up in part because associated weapons technology has recently moved in a more mature direction.
Five years later, Air Force microwave and laser weapons took down some drones in New Mexico’s White Sands Missile Range. And this past spring, a Navy laser shooter knocked out a fake cruise missile, in that same desert, where scientists also tested the first nuclear weapon.
Do I look to be in a gaming mood?
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
AFRL is now developing a weapon called THOR: the Tactical High-Power Operational Responder. THOR uses high-power microwaves to mess up electronics, a concept you essentially understand if you’ve ever (for some reason) tried to nuke your cellphone.
After THOR — which lives inside a 20-foot shipping container and can hitch rides around the world on C-130 aircraft — sets a target, an operator pulls the trigger and releases a burst of microwaves that last merely a nanosecond. Its ideal “enemy”: a swarm of small drones.
Last year, a test revealed that THOR’s microwaves could indeed knock things out of the sky. It worked very well, “neutralizing” objects 100 percent of the time.
Now, AFRL wants to amp up DE research for the next generation of scientists.
That goal also appealed to Schamiloglu at the University of New Mexico. He wanted the school to take a closer look at laser DE, since it had long focused on microwaves.
After the Air Force and UNM teamed up, legislators designated money in the AFRL budget to back UNM’s Directed Energy Center, which aims to train future pew-pew gurus. “They will work not only at the Air Force Research Lab, but at the numerous contractors that support the research that’s ongoing,” says Matthew Fetrow, technology outreach lead at AFRL.
It’s not all light
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
These scientists have plenty to improve on: While DE weapons are faring better than they have in the past, they’re not perfect. They can be stymied by natural forces like rain and fog — the water in the air can mess with their beams, kind of like it does with your headlights. These systems can also be big and cumbersome. Sometimes, they’re super power-hungry.
Outside of all that tech trouble, the weapons raise some ethical concerns. International law doesn’t deal much with DE, and regulations may be important to help ensure it’s used responsibly and humanely. There is a UN document, “Article 1 of the Protocol on Blinding Lasers,” which states that no one can use “laser weapons specifically designed, as their sole combat function or as one of their combat functions, to cause permanent blindness to unenhanced vision.”
Research into DE technology isn’t just useful on the battlefield. For example, industrial giant Honeywell has a whole division dedicated to directed energy’s commercial applications.
These span everything from fusion energy to laser welding and cutting. The company is also interested in the same cooling systems that keep DE weapons chill: Those can ice down batteries and radars anywhere.
Research into DE technology isn’t just useful on the battlefield.
Research into DE technology isn’t just useful on the battlefield.
On the academic side, particle accelerators also need highly focused, extremely energetic beams of particles, which can improve with advances in beams of pure energy. At Purdue University, a researcher named Allen Garner invented a microwave device in 2021 that has equal utility for quirking enemy electronics, sterilizing medical equipment, and performing noninvasive medical procedures (snip-pew snip-pew).
Then, there are the less obvious applications. “We’ve actually been seeing some interesting concepts come forward from companies — in particular, small companies — looking at using microwaves, high-power sources, to help in mining,” says Fetrow of AFRL, “which surprised the daylights out of me.”
These futuristic "energy weapons" could finally bring sci-fi to the battlefield
Right now, AFRL and UNM’s joint focus is on increasing the power you can get out of both microwave and laser systems. With microwaves, that involves building better amplifiers, which are essentially volume knobs. As for lasers, they’re trying to improve the fiber-optic cables that whip up the light beams. “The holy grail right now is to really push the power, how much power can you generate from these fiber lasers,” says Schamiloglu.
But researchers are in a bind: As power increases, so does heat, and the glass in the system gets too warm. UNM has been working on novel ways to cool those fibers, so the laser can pump out even more power.
AFRL is also working on the next generation of THOR technology that’s meant to be lighter and more energy-efficient. It goes by the name Mjölnir, THOR’s mighty hammer — “THOR’s Massless Hammer” apparently wasn’t catchy enough.
It may take a while before such a hammer can be hurled on the battlefield, but in the coming decades, the battlefield could start to resemble a sci-fi flick.

GROTE RUIMTESTEEN ONTDEKT DIE IN DE TOEKOMST EEN BEDREIGING VOOR DE AARDE ZOU KUNNEN GAAN VORMEN
GROTE RUIMTESTEEN ONTDEKT DIE IN DE TOEKOMST EEN BEDREIGING VOOR DE AARDE ZOU KUNNEN GAAN VORMEN
Caroline Kraaijvanger
Met een omvang van zo’n 1,5 kilometer is het de grootste potentieel gevaarlijke planetoïde die in de afgelopen acht jaar is ontdekt.
De ruimtesteen heeft de naam 2022 AP7 gekregen. Astronomen ontdekten de planetoïde met behulp van de Dark Energy Camera (DECam), gemonteerd op de Victor M. Blanco 4-meter Telescope in Chili.
Bijzonder Het is een vrij bijzondere ontdekking, omdat 2022 AP7 een flinke jongen is; met een geschatte diameter van zo’n 1,5 kilometer is het de grootste potentieel gevaarlijke planetoïde (zie kader) die in de afgelopen acht jaar is ontdekt.
Potentieel gevaarlijk 2022 AP7 is een zogenoemde aardscheerder. Met deze term wordt verwezen naar planetoïden (of kometen) die zich in de nabijheid van de aarde wagen. Wanneer zo’n ruimtesteen groter is dan 140 meter én een baan heeft die de baan van de aarde daadwerkelijk doorkruist, krijgt deze automatisch de aanduiding ‘potentieel gevaarlijk object’. Hoewel dat tamelijk angstaanjagend klinkt, wil dat dus zeker niet zeggen dat de ruimtesteen of komeet ook daadwerkelijk op ramkoers met de aarde komt te liggen en van de meeste potentieel gevaarlijke ruimtestenen weten we zelfs dat we er in ieder geval de komende eeuwen niets van te vrezen hebben. Ook de 1,5 kilometer grote 2022 AP7 heeft een baan die de baan van de aarde kruist en krijgt dus het stempel ‘potentieel gevaarlijk’. Maar dat wil dus niet zeggen dat de steen gedoemd is om op aarde in te slaan. ‘Potentieel gevaarlijk’ geeft simpelweg aan dat een ruimtesteen in de toekomst misschien een gevaar kan gaan vormen voor de aarde. Door dergelijke potentieel gevaarlijke ruimtestenen nauwlettend in de gaten te houden en een nauwkeuriger beeld van hun baan te verkrijgen, proberen astronomen vervolgens beter te voorspellen wanneer zo’n ruimtesteen bij de aarde in de buurt komt en of deze daadwerkelijk een gevaar kan gaan vormen voor onze planeet. Vaak zien we dat op basis van dergelijk vervolgonderzoek al spoedig kan worden uitgesloten dat een potentieel gevaarlijk object in ieder geval in de komende eeuw(en) echt gevaarlijk wordt.
Lastig waar te nemen Juist het feit dat 2022 AP7 zich in de binnenste regionen van het zonnestelsel – oftewel nabij de aarde – ophoudt, maakte het lastig om deze te detecteren. De gloed van de zon zit namelijk enorm in de weg. Op jacht naar aardscheerders kiezen astronomen er daarom heel bewust voor om in de schemering hun blik op het heelal te richten. Maar zelfs dan is het geen gelopen race, omdat zonlicht nog steeds een enigszins storende factor is én ze genoodzaakt zijn om nabij de horizon te observeren en dus ook nog eens geplaagd worden door de dikke aardatmosfeer die observaties bemoeilijkt. Dat het nu toch gelukt is om 2022 AP7 waar te nemen, is dan ook zeker grotendeels te danken aan de enorme gevoeligheid van DECam. Met de camera kan niet alleen een groot deel van het heelal worden afgespeurd, maar is het tevens mogelijk om juist heel lichtzwakke objecten te spotten.
Nog twee planetoïden Naast 2022 AP7 presenteren de astronomen ook de ontdekking van twee andere aardscheerders: 2021 LJ4 en 2021 PH27. Beide planetoïden behoren niet tot de potentieel gevaarlijke objecten; hun banen blijven keurig binnen de baan van de aarde. Overigens is dat ergens ook weer wel bijzonder; tot op heden zijn ons slechts 25 ruimtestenen bekend die zich nooit buiten de omloopbaan van de aarde bewegen.
Warm 2021 PH27 verdient daarbij nog wat extra aandacht. De ruimtesteen gaat voor nu namelijk de boeken in als de planetoïde die zich het dichtst bij de zon begeeft. Die ritjes langs onze moederster laten de ruimtesteen niet koud; de temperatuur van het oppervlak van de planetoïde zou door de nabijheid van de zon hoog genoeg oplopen om lood (met een smeltpunt van 327,5 graad Celsius) te doen smelten.
Toekomstige ontdekkingen Dat er in het hart van ons zonnestelsel nog meer te ontdekken valt, lijkt vast te staan. Maar of er nog heel veel grote ruimtestenen – zoals 2022 AP7 op ontdekking wachten – is twijfelachtig. “Met ons onderzoek in de schemering zoeken we binnen de banen van de aarde en Venus naar planetoïden,” legt onderzoeker Scott S. Sheppard uit. “Tot op heden hebben we twee grote aardscheerders gevonden die ongeveer 1 kilometer groot zijn (…) Er wachten waarschijnlijk slechts enkele aardscheerders met vergelijkbare omvang op ontdekking en die grote, onontdekte planetoïden hebben waarschijnlijk banen die ze het grootste deel van de tijd binnen de banen van de aarde en Venus houden.”
Ondertussen gaat de zoektocht naar die onontdekte planetoïden natuurlijk stug door. Die zoektocht is overigens niet alleen belangrijk met het oog op de bescherming van onze planeet, maar kan ook bijdragen aan een beter begrip van de verspreiding van kleine hemellichamen in ons zonnestelsel. En dat kan weer meer inzicht geven in hoe planetoïden door het binnenste van ons zonnestelsel reizen en hoe de interactie met de zwaartekracht en hitte van de zon bijdraagt aan het uiteenvallen van ruimtestenen. “Dit is een unieke kans om beter te begrijpen wat voor soort objecten er in het binnenste van het zonnestelsel schuilgaan,” vindt Sheppard.
THESE TINY MAGNETIC ROBOTS CAN INFILTRATE TUMORS — AND MAYBE DESTROY CANCER
THESE TINY MAGNETIC ROBOTS CAN INFILTRATE TUMORS — AND MAYBE DESTROY CANCER
Bacterial cancer treatments are coming back into fashion (with some futuristic upgrades).
DOCTORS AREN’T ALWAYS able to remove hard-to-reach cancerous tumors with surgery, so some patients must receive aggressive chemotherapy and/or radiation therapy — a combination that can prove ineffective.
But a new cancer treatment may offer a way to take down inoperable tumors with pinpoint accuracy, no radiation required.
Researchers have figured out how to deliver cancer-killing compounds (called enterotoxins) to tumors using bionic bacteria that are steered by a magnetic field. These “micro-robots” can hunt down and converge on a specific tumor, then shrink it by releasing the bacteria's own naturally produced anti-cancer chemicals. The results were recently published in the journal Science.
This high-tech cancer treatment could allow magnetic bacteria (grey) to squeeze through narrow spaces between cells and attack tumors.

“Cancer is such a complex disease, it’s hard to combat it with one weapon,” says Simone Schürle-Finke, a micro-roboticist at the Swiss Federal Institute of Technology in Zürich, Switzerland and the first author of the new study.
She and her lab hope that these magnetic, bacteria-riding little robots will offer a precise and powerful addition to the cancer treatment toolbox.
HERE’S THE BACKGROUND
The idea of curing cancerous tumors with bacteria is surprisingly old. American oncologist William Coley first started injecting his patients with a mixture of dead bacteria and bacterial proteins in the 1890s. After he reported successfully treating people with otherwise inoperable tumors, his work garnered equal parts enthusiasm and skepticism from the medical community.
Despite Coley’s vocal critics (including members of the American Medical Association), his formula, dubbed “Coley’s toxins,” would go on to be sold as a cancer treatment for the next seventy years. By the 1960s, though, Coley’s toxins had all but fallen by the wayside in favor of promising new treatments, like radiation and chemotherapy.
William Coley used bacteria like Streptococcus pyogenes to treat cancer.

Significant interest in bacteria as a cancer treatment didn’t re-emerge until the dawn of CRISPR, a revolutionary bioengineering technology, in the early 2010s. And today, labs are realizing the limits of today’s standard cancer interventions, such as their imprecise nature and harmful side effects.
Today, researchers like Schürle-Finke and her team are putting micro-robots inside genetically engineered bacteria to target cancerous growths like never before. Once these microbes reach a tumor, “you basically have a little nano-factory that continues to release molecules that can be toxic to cancer cells,” she says. The only issue? Figuring out how to get the bacteria bots in place.
WHAT’S NEW
Many inoperable tumors can’t be addressed by surgery simply because of their location — they may be too hard to reach with a knife, let alone inject with a syringe full of bacterial cyborgs. This means that researchers have had to brainstorm some creative ways to navigate therapeutic bacteria toward cancer cells.
Schürle-Finke was pondering this conundrum when inspiration struck. “Maybe I could help with magnetic guidance,” she recalled thinking. Most bacteria can’t be pushed around with magnets, but as luck would have it, one special group of aquatic bacteria does: magnetotactic bacteria, which use the tiny iron crystals produced in their bodies like an internal compass.

So she took the next logical step — ordering some magnetotactic bacteria online. “I was surprised,” Schürle-Finke says, “You can just buy them.”
Back in the lab, her team got to work equipping the bacteria with fluorescent tags and microcontrollers. In these genetically engineered bacteria, the microcontrollers propel them to release cancer-fighting compounds on demand.
Then, they injected the bacteria bots into tumor-ridden mice. Using an externally generated magnetic field, scientists were able to successfully direct the bacteria and park them on the mice’s tumors with more than three times the precision of the control group (which wasn’t subjected to a magnetic field.)
WHAT’S NEXT
Though this study offers a solid proof-of-concept, micro-robotic bacteria technology still needs to be refined before it becomes a mainstream cancer treatment.
For one thing, “these bacteria that we tested, they’re quite foreign to the human body,” Schürle-Finke says, and they don’t naturally produce cancer-fighting compounds.
In the future, bioengineers may try to identify the cluster of genes responsible for producing magnetotactic bacteria's magnetic iron pellets and transfer it to a more familiar model organism, like a harmless strain of E. coli, Salmonella, or Clostridium.
They’ll also have to address the physical limits to generating a magnetic field. While the field they generated was able to penetrate a tiny mouse’s tissue, it may weaken and become useless as it passes through a thicker and more complex human body.
Still, Schürle-Finke is excited about the possibility that bacterial therapy holds. And she’s ready to continue bridging the gap across scientific disciplines, from oncology to microbiology to robotics. “I think it’s beautiful that we’re experiencing this convergence of sciences,” she says.

FIRST-EVER LAB-GROWN BLOOD COULD CHANGE MEDICINE FOREVER
FIRST-EVER LAB-GROWN BLOOD COULD CHANGE MEDICINE FOREVER
For the first time ever, scientists have given patients red bloodcells that were grown in a lab. This feat is part of a clinical trial in England looking into the safety of the cutting-edge technique, which could help tackle the ongoing blood supply shortage that was worsened by the pandemic.
The trial is a collaboration between institutions including the University of Bristol, the University of Cambridge, and the National Health Service.
Regular transfusions can be life-saving for people with conditions like sickle cell disease, which affects the shape of red blood cells and can block blood flow, and thalassemia, which causes the body to produce too little of a protein called hemoglobin.
Now, these lab-grown red blood cells could stretch sparse donations into larger volumes. The procedure could also help address the need for more blood from Black donors — sickle cell disease is prevalent among Black people, and blood is most compatible when donated from people of the same race or similar ethnicity.
And unlike donor blood, which can contain relatively old cells, these lab-grown cells are guaranteed to be fresh. This means they can last longer and perform better, reducing the need for frequent transfusions. When people receive lots of transfusions, they also run the risk of developing too much iron in their bodies.
HOW TO GROW BLOOD CELLS

The scientists started with a regular blood donation and used magnetic beads to pinpoint the flexible stem cells that can morph into red blood cells, CNBC reported.
Then, they put the stem cells in a nutrient solution for 18 to 21 days, which nudges the cells to proliferate and grow into more mature cells, according to The Guardian. Then, they tagged the cells with a radioactive substance to track them in blood samples from trial participants over the six months following the first injection of cells.
So far, two healthy volunteers have received the lab-grown red blood cells, and they haven’t reported any negative side effects. Next up, the team will give a minimum of 10 participants two “mini” transfusions at least four months apart — one consisting of standard donated red blood cells and another composed of lab-grown ones.
The researchers will analyze patient blood samples to determine whether the lab-grown red blood cells will last longer than the ones made in the body. While further research is needed, this marks a major step forward in treating blood disorders.
“The need for normal blood donations to provide the vast majority of blood will remain,” says Farrukh Shah, the medical director of tranfusion at NHS Blood and Transplant. “But the potential for this work to benefit hard-to-transfuse patients is very significant.”
