Op zo’n 5 miljard lichtjaar afstand heerst de immense sterrenstelselcluster MACS J1149. De James Webb-ruimtetelescoop legt dit kosmische zwaargewicht nu met ongekende scherpte vast en onthult hoe zijn verpletterende zwaartekracht het licht van het vroege heelal buigt en vervormt.

Diep in het sterrenbeeld Leeuw (Leo), op een duizelingwekkende afstand van ongeveer 5 miljard lichtjaar, heerst een ware titan: sterrenstelselcluster MACS J1149.5+2223. Deze verzameling van honderden sterrenstelsels, bijeengehouden door de allesbepalende zwaartekracht, is nu vastgelegd in verbluffend detail door de James Webb-ruimtetelescoop. Het nieuwe beeld onthult niet alleen de indrukwekkende inwoners van de cluster zelf, maar ook hoe dit kosmische zwaargewicht fungeert als een natuurlijke telescoop voor het observeren van de verste uithoeken van het universum.

De James Webb-ruimtetelescoop legde deze opname van MACS J1149.5+2223 vast met zijn Near-Infrared Camera (NIRCam), een compositie van zes verschillende golflengten van 0,9 tot 4,44 micrometer, om de structuur en samenstelling van de sterrenstelsels in ongekend detail te onthullen.

Een natuurlijk zwaartekrachtlens laboratorium

De werkelijke kracht van MACS J1149 schuilt in zijn kolossale massa. De zwaartekracht van deze cluster is zo immens dat ze de structuur van ruimtetijd rondom zich vervormt. Licht van sterrenstelsels die nog eens véél verder weg staan, moet op zijn miljarden jaren durende reis naar de aarde door dit vervormde gebied reizen. Het gevolg is een fenomeen dat astronomen gravitationele lensing noemen: het licht wordt afgebogen en versterkt, alsof het door een kosmisch vergrootglas gaat. Op Webbs opname (hierboven) is dit overal zichtbaar, van subtiel uitgerekte sterrenstelsels tot bizarre, gerekte vormen.

Een kosmische celebrity onder de loep

Deze eigenschap maakt MACS J1149 tot een ware ‘celebrity’ voor astronomen. De cluster was eerder al één van de zes nauwlettend onderzochte regio’s door het baanbrekende Frontier Fields-programma van de Hubble-ruimtetelescoop, specifiek geselecteerd vanwege zijn sterke lenswerking. Ook de Very Large Telescope van de Europese Zuidelijke Sterrenwacht (ESO) heeft zijn blik op de cluster gericht, maar ook radiogrondtelescopen en orbitale röntgentelescopen zoals Chandra hebben MACS J1149 vaker onderzocht. Recent onderzoek gebruikt deze voorgaande waarnemingen in combinatie met nieuwe gegevens om de massa-verdeling binnen dergelijke clusters en hun rol in de evolutie van sterrenstelsels verder te duiden.

Deze eerdere opname van de Hubble-ruimtetelescoop toont MACS J1149 en benadrukt de ontdekking van het zeer verre sterrenstelsel MACS1149-JD, wiens licht door de cluster werd versterkt.

Postman (STScI), and the CLASH Team Een combinatie van Hubble- en VLT-waarnemingen (2015) legde een supernova vast in een verder gelegen achtergrondstelsel, wiens licht door MACS J1149 werd afgebogen en in viervoud als ‘Einstein kruis’ oplichtte.

Deze Hubble-opname toont een volgende ontdekking die mogelijk werd gemaakt door de lenswerking van MACS J1149: de ster LS1, ook wel Icarus genoemd. Het licht van deze blauwe superreus werd maar liefst 2.000 keer versterkt, waardoor hij – hoewel zijn licht er bijna 9 miljard jaar over deed om ons te bereiken – kon worden waargenomen. Destijds (studie uit 2018) was dit de verst en oudst gelegen individuele ster gekend door astronomen. Het is een baanbrekend voorbeeld van gravitationele microlensing door een cluster een object van slechts enkele zonsmassa’s tijdelijk extra uitvergroot, zoals te begrijpen valt uit de rechter details; de ster lichtte slechts tijdelijk op in observaties uit 2016.

Röntgenstraling (blauw) van NASA’s Chandra-observatorium onthult heet gas van miljoenen graden. Optisch licht (rood, groen, blauw) van Hubble toont de sterrenstelsels, terwijl radiogolven (roze) van de Very Large Array schokgolven en turbulentie in kaart brengen – tekenen van botsende clusters. Gecombineerde informatie uit een legio van telescopen doorheen meerdere jaren staan toe onder andere de zwaartekrachtwerking van de clusters goed in kaart te brengen.

Webbs uitzonderlijke gevoeligheid in het infrarood gaat nu een stap verder. Zijn instrumenten, zoals NIRSpec en NIRCam, worden ingezet in programma’s zoals CANUCS om via clusters als MACS J1149 de allervroegste sterrenstelsels te bestuderen. Ze ontrafelen hun stervorming, chemie en de rol die ze speelden tijdens het tijdperk van de reïonisatie, toen de eerste lichtbronnen de kosmische duisternis doorbraken na de oerknal.

Het infrarood licht doorheen verschillende filters van de uiterst krachtige James Webb ruimtetelescoop (links) permitteert onderzoekers sterke zwaartekrachtlenzen zoals MACS 1149 in hun voordeel te gebruiken. Alwaar de vorm en zwaartekrachtwerking van MACS 1149 gekend is en gemodelleerd in een ‘bCGs model’ (midden), kan deze van de oorspronkelijke opname worden weggefilterd om een beeld te vormen van wat zich daarachter bevindt (rechts) om nader onderzocht te worden.

We schreven vaker over dit onderwerp, lees bijvoorbeeld ook ‘Eén jaar na de lancering van James Webb kunnen astronomen hun geluk niet op: de telescoop maakt het onzichtbare en ondenkbare zichtbaar‘ of ‘De eerste sterrenstelsels in het universum waren veel helderder dan verwacht‘.

Een venster op het vroege heelal

De nieuwe James Webb-opname is dus meer dan een adembenemend plaatje. Het is het begin van een nieuw hoofdstuk in de studie van deze kosmische reus. Door het lensvermogen van MACS J1149 te combineren met Webbs ongeëvenaarde scherpte, kunnen astronomen verder terugkijken in de tijd dan ooit tevoren. Op deze manier blijft deze cluster, een reus op 5 miljard lichtjaar afstand, ons een uniek venster bieden op de geboorte en evolutie van de eerste structuren in ons universum.

UFOs, a Mother With Supernatural Powers, and Rap Battles With a Third Eye: Rotterdam Sets HBF+Brazil Pilot Projects

The Hubert Bals Fund has taken “a long-lasting interest in Brazilian cinema … from the success of ‘I’m Still Here’ to the outstanding path currently trailed by ‘The Secret Agent’.”

NASA

NASA is gearing up for the first crewed journey to the Moon in over half a century, a mission that could launch as soon as two weeks from now.

And next year, the agency will finally attempt to return astronauts to the lunar surface itself as part of its Artemis 3 mission, which will dramatically increase the already considerable stakes.

Particularly when it comes to stepping out of the spacecraft — the agency has yet to pick between Blue Origin and SpaceX’s offerings in that regard — staying protected from the extreme temperature swings, space radiation, and lack of atmosphere is extremely challenging.

That’s not to mention the physical limitations of an extremely bulky spacesuit, which could physically tax astronauts even more than stepping outside of the International Space Station during a spacewalk.

As Ars Technica reports, former NASA astronaut and microbiologist Kate Rubins, who retired last year and has logged 300 days in space, recently voiced her concerns over the Moon suit that private space company Axiom Space has been developing for NASA as part of a $228 million contract.

“What I think we have on the Moon that we don’t really have on the space station that I want people to recognize is an extreme physical stress,” she said during a recent meeting of the National Academies of Sciences, Engineering, and Medicine.

Besides not getting any sleep, Rubin warned that people will be “in these suits for eight or nine hours” and doing extravehicular activities (EVAs) “every day.”

Compared to the suits NASA astronauts wore during the Apollo missions, the Axiom Space suit is considerably heavier. While a sixth of gravity will greatly alleviate some of that heft, they still weigh in at 300 pounds. At the same time, Moon walkers will enjoy greatly enhanced flexibility, allowing them to kneel down to pick up objects, for instance.

“I think the suits are better than Apollo, but I don’t think they are great right now,” Rubin warned, noting “flexibility issues” and the reality that “people are going to be falling over.”

In remarks directly to Ars, Rubin elaborated, emphasizing that the suits are “definitely much better than Apollo,” but remain “still quite heavy.”

Even something as simple as getting back up after a fall — as demonstrated by the many Apollo astronauts who took a tumble while on the Moon — involves a type of “jumping pushup,” as Rubins told Ars, which is a “non-trivial” and “risky maneuver.”

Not everybody is as concerned about the Axiom Space suit. Current NASA astronaut and physician Mike Barratt argued in remarks during the committee meeting that the “suit is getting there,” pointing out that “we’ve got 700 hours of pressurized experience in it right now.”

“Bending down in the suit is really not too bad at all,” he added.

NASA still plans to conduct plenty of tests involving the suit, including parabolic flight, which can simulate the partial gravity of the Moon’s surface. The agency has already put the suit through its paces underwater at NASA’s Neutral Buoyancy Lab.

The agency has until sometime next year to finalize the design for its long-awaited Artemis 3 mission to the lunar surface. At the same time, NASA still has plenty of decisions to make, including how to get down to the lunar surface in the first place.

NASA shared an unusual photo taken by the Curiosity mission. It shows the rover’s “night shift.”

The Curiosity rover is equipped with LED lights. They are part of the MAHLI camera mounted at the end of its robotic arm. Sometimes scientists use them during the day to illuminate areas that are in shadow, such as the interior of boreholes and intake tubes leading to instruments at the bottom of the rover.

In the earlier stages of the mission, the Curiosity team also used these LEDs at night to search for layers or other features on the walls of drill holes that would help them better understand the composition of the rock. But since the mission changed its drilling method, the holes have become too rough and dusty to see any details. 

However, Curiosity recently used LEDs again at night. This happened after drilling a rock called Nevado Sajama on November 13, 2025. After studying the images, the mission specialists noticed that the walls of the borehole were smooth enough to attempt to find layers, and decided to try illuminating the borehole at night. It is this operation that is captured in the image presented.

The drilling at Nevado Sajama was carried out during an exploration of a region full of geological formations known as “boxworks.” These formations crisscross the surface for many kilometers and, when viewed from space, look like giant spider webs.

A momentous event in the history of space exploration is about to take place: for the first time in 54 years, humans will return to the Moon. As part of the Artemis II mission, four astronauts will orbit the Moon and then return to Earth. The entire journey will take ten days.

The Artemis II mission would not have been possible without Artemis I. As part of Artemis I, NASA launched the super-heavy SLS rocket for the first time and tested the Orion spacecraft in deep space. The experience gained during its implementation laid the foundation for the further development of the lunar program. With the launch of Artemis II fast approaching, let’s take a look back at how the predecessor mission went and admire some of its best photos.

Artemis I was launched into space on November 16, 2022. This launch marked the debut of the super-heavy SLS rocket, which is capable of carrying up to 95 tons of cargo into orbit. Incidentally, its first-stage engines, boosters, and side boosters were inherited from the Space Shuttle program.

Eight hours after launch, the upper stage of the SLS performed a maneuver that directed Orion toward the Moon, after which it separated from the spacecraft and was directed into Earth’s atmosphere.

The journey to the Moon took five days. On November 21, Orion performed a close flyby of the Moon, after which it activated its main engine, entering a distant retrograde orbit around the satellite.

On December 11, 2022, Orion entered Earth’s atmosphere at a speed of 11.2 km/s, which is much higher than missions returning to Earth from the ISS. The spacecraft’s heat shield sustained more damage than expected, but still reliably protected the contents of the crew capsule.

With the first launch window for Artemis II now just days away, NASA has shared a glimpse inside the cramped quarters of the Orion spacecraft.

Four astronauts – Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen – will spend 10 days living inside the capsule as they whizz around the moon.

During that time, the crew will stay in a tiny, equipment–filled space, no larger than the back of a Ford Transit.

While NASA says it will use the mission to learn how crews adjust to tight quarters, space fans have pointed out one very obvious problem.

Although Orion is equipped with a toilet and washing facilities, many commenters wondered just how hygienic the capsule will be after a week and a half in space.

On X (formerly Twitter), one sceptical commenter wrote: 'No mention of how they will be in extremely close quarters and will have to change each other's diapers and wipe.

'The smell would be intolerable.'

Another concerned commenter asked: 'Do they change their clothes at all and if so, since there is a woman in the crew, is there privacy for that and toileting?'

On X, some space enthusiasts had serious concerns about the smell that could be caused by four astronauts living, exercising, and using the bathroom in such a small space 

During the Artemis II mission, the four–person crew will launch from Kennedy Space Centre on a round trip passing around the far side of the moon.

Once their Space Launch System (SLS) rocket has pushed the astronauts out into orbit, the early stages will detach and leave Orion to drift by itself through space.

While Orion has 30 per cent more space than the Apollo capsule, it is still absolutely tiny for four people.

Measuring just 3.35 metres (11 feet) in height and five metres (16.5 feet) in diameter at the base, Orion has a habitable volume of just 9.34 cubic metres (330 cubic feet).

For comparison, a Ford Transit van typically has 10 cubic metres (353 cubic feet) of storage in the back.

Conditions are so cramped that NASA wants to study how the crew physically and psychologically adapt to their time in space.

In a video posted to X, NASA explains: 'To better understand how isolation, confinement, and other aspects of spaceflight affect human health and performance, Artemis II crew members will evaluate their activity levels, sleep patterns, movements and interactions for a study called Artemis Research for Crew Health and Readiness – or ARCHR for short.'

The astronauts will wear sports–watch–like wristbands to measure their movements and sleep patterns in real time, as well as completing surveys and motor control tests before and after flight.

Other concerned space fans were worried that there might not be privacy for washing, changing, or using the toilet in the tiny confines of the Orion capsule 

Despite the obvious challenges, a number of commenters on social media were bizarrely unimpressed by the technological and human achievements of spaceflight 

The crew will sleep for eight hours per day in sleeping bag–like hammocks that attach to handrails (pictured) 

In the biggest upgrade over Apollo, Orion features a separate toilet compartment hidden behind a panel in the floor (circled in red)

The Artemis II crew

Reid Wiseman – Commander 

- A US Navy aviator and test pilot with 27 years of experience.

- Wiseman has previously spent 165 days in space onboard the ISS

Victor Glover – Pilot

- A US Navy aviator and test pilot with 3,500 flight hours in more than 40 aircraft 

- Glover served as Flight Engineer on the ISS during a 168–day mission

Christna Koch – Mission specialist

- An engineer and scientist specialising in electrical engineering

- Holds the record for longest spaceflight by a woman, spending consecutive days on the ISS

Jeremy Hansen – Mission specialist

- Selected by the Canadian Space Agency to join Artemis II

- A Canadian Armed Forces fighter pilot, physicist, and experienced aquanaut

However, despite these obvious challenges, some space enthusiasts remained bizarrely unimpressed.

One commenter wrote on X: 'Relax. Once you get used to it, it'll be fine. I could do the trip to Mars in a freakin' Apollo capsule.'

Another said: 'So NASA's gonna put Fitbits on the astronauts? Cool, I've been wearing one for over three years.'

Despite the small amount of space, NASA has managed to fit in a few comforts that should make the journey more bearable.

For those concerned about the smell, Orion is fitted with a modified version of the toilet from the International Space Station known as the Universal Waste Management System.

This is essentially an elaborate vacuum cleaner with a seat and a specialised nozzle that operates by 'using air flow to pull fluid and solid waste away from the body'.

Compared to the toilet on the ISS, Orion's lavatory has been modified to fit in an even smaller space and to be more practical for female astronauts.

Perhaps most importantly, NASA has even found enough space on Orion to fit the toilet in its own tiny room.

The toilet room will also allow astronauts to wash in relative privacy, using liquid soap, flannels and rinseless shampoo to stay clean. Pictured: A training mockup of the Artemis II toilet used to practice on Earth 

The crew will use a similar toilet to the one found on the ISS, known as the Universal Waste Management System (pictured), that uses 'air flow to pull fluid and solid waste away' 

Orion even has room for a compact gym with a flywheel system (pictured) that allows for simple resistance exercises 

On Apollo, astronauts had to simply float in a corner while doing their business, but Artemis II's crew have the luxury of a tiny cabin in the 'floor' of the capsule.

Speaking in a video blog, Artemis II crewmember Jeremy Hansen described this as 'the one place we can go during the mission where we can actually feel like we're alone for a moment.'

This hygiene bay also offers the crew a place to wash in relative privacy, using liquid soap, flannels, and rinseless shampoo to remain clean.

To stay healthy and prevent muscle atrophy while in microgravity, Orion even packs in a compact gym for the astronauts to use.

The crew will use a flywheel device for simple resistance exercises like rowing, squats, and deadlifts for 30 minutes every day.

Is THIS where aliens are hiding? NASA discovers an exoplanet 146 light–years away that's 'remarkably similar to Earth' – and it could be habitable

• READ MORE: Scientists baffled by a LEMON-shaped planet

By SHIVALI BEST, SCIENCE & TECHNOLOGY EDITOR 

It's one of the biggest unanswered questions in science: are there aliens out there, and if so, where are they hiding?

Now, a discovery by NASA raising the tantalising possibility that we're not alone after all. 

The US space agency has discovered an exoplanet 146 light–years away that is 'remarkably similar to Earth'. 

Dubbed HD 137010 b, the planet might fall just within the outer edges of its star's 'habitable zone', meaning there could be liquid water on its surface and a suitable atmosphere for life. 

However, any potential aliens living on this planet would need to be well adapted for cold weather. 

'Although of a stellar type similar to our Sun, the star, HD 137010, is cooler and dimmer,' NASA explained. 

'That could mean a planetary surface temperature no higher than –90°F (–68°C). 

'By comparison, the average surface temperature on Mars runs about –85°F (–65°C).'

Dubbed HD 137010 b, the planet might fall just within the outer edges of its star's 'habitable zone', meaning there could be liquid water on its surface and a suitable atmosphere for life

NASA's scientists discovered the rocky exoplanet using data gathered by the Kepler Space Telescope.

This discovery comes from a single 'transit' – the planet crossing its star's face – which was detected during Kepler's second mission, K2. 

While one transit doesn't sound like much, this was enough for the scientists to estimate the exoplanet's orbital period. 

By tracking the time it took for the planet's shadow to move across its sun's face, the team estimated that the planet has an orbital period of 10 hours, compared to Earth's 13 hours. 

Their calculations also suggest it's probably freezing, although there is a chance HD 137010 b could turn out to be a temperate or even a watery world, according to NASA. 

'It would just need an atmosphere richer in carbon dioxide than our own,' the team explained. 

Based on modelling of the planet's possible atmospheres, NASA says there is a 40 per cent chance that the planet falls within the 'conservative' habitable zone around the star, and a 51 per cent chance that it falls within the broader 'optimistic' habitable zone.

'The planet has about a 50–50 chance of falling beyond the habitable zone entirely,' the experts cautioned. 

To confirm whether or not the planet is habitable, the researchers will now conduct follow–up observations – although they admit this is going to be 'tricky'. 

'The planet's orbital distance, so similar to Earth's, means such transits happen far less often than for planets in tighter orbits around their stars (it's a big reason why exoplanets with Earth–like orbits are so hard to detect in the first place),' NASA explained. 

'With luck, confirmation could come from further observation by the successor to Kepler/K2, NASA's TESS (the Transiting Exoplanet Survey Satellite), the still–functioning workhorse for planetary detection, or from the European Space Agency's CHEOPS (CHaracterising ExOPlanets Satellite).

'Otherwise, gathering further data on planet HD 137010 b might have to wait for the next generation of space telescopes.'

KEY DISCOVERIES IN HUMANITY'S SEARCH FOR ALIEN LIFE

Discovery of pulsars

British astronomer Dame Jocelyn Bell Burnell was the first person to discover a pulsar in 1967 when she spotted a radio pulsar.

Since then other types of pulsars that emit X-rays and gamma rays have also been spotted.

Pulsars are essentially rotating, highly magnetised neutron stars but when they were first discovered it was believed they could have come from aliens.

'Wow!' radio signal

In 1977, an astronomer looking for alien life in the night sky above Ohio spotted a radio signal so powerful that he excitedly wrote 'Wow!' next to his data.

In 1977, an astronomer looking for alien life in the night sky above Ohio spotted a radio signal so powerful that he excitedly wrote 'Wow!' next to his data

The 72-second blast, spotted by Dr Jerry Ehman through a radio telescope, came from Sagittarius but matched no known celestial object.

Conspiracy theorists have since claimed that the 'Wow! signal', which was 30 times stronger than background radiation, was a message from intelligent extraterrestrials.

Fossilised Martian microbes

In 1996 Nasa and the White House made the explosive announcement that the rock contained traces of Martian bugs.

The meteorite, catalogued as Allen Hills (ALH) 84001, crashed onto the frozen wastes of Antarctica 13,000 years ago and was recovered in 1984. 

Photographs were released showing elongated segmented objects that appeared strikingly lifelike.

However, the excitement did not last long. Other scientists questioned whether the meteorite samples were contaminated. 

They also argued that heat generated when the rock was blasted into space may have created mineral structures that could be mistaken for microfossils. 

Behaviour of Tabby's Star in 2005 

The star, otherwise known as KIC 8462852, is located 1,400 light years away and has baffled astronomers since being discovered in 2015.

It dims at a much faster rate than other stars, which some experts have suggested is a sign of aliens harnessing the energy of a star.

Recent studies have 'eliminated the possibility of an alien megastructure', and instead, suggests that a ring of dust could be causing the strange signals.

Exoplanets in the Goldilocks zone in 2017 

In February 2017 astronomers announced they had spotted a star system with planets that could support life just 39 light years away.

Seven Earth-like planets were discovered orbiting nearby dwarf star 'Trappist-1', and all of them could have water at their surface, one of the key components of life.

Three of the planets have such good conditions, that scientists say life may have already evolved on them. 

Researchers claim that they will know whether or not there is life on any of the planets within a decade, and said: 'This is just the beginning.'

On January 27, 2026, the Bulletin of Atomic Scientists moved the symbolic Doomsday Clock forward once again, now just 85 seconds before midnight, the closest humanity has come in nearly eight decades and for anyone paying attention, the message is hard to miss: something is off. 

The latest update pointed to an expanding set of destabilizing forces — from nuclear stockpiles and accelerating climate breakdown to disruptive AI capabilities and advances in synthetic biology. Taken together, these technologies and geopolitical tensions form what the group calls a high risk landscape with almost no guardrails. 

“Every second counts and we are running out of time,” warned Alexandra Bell, the organization’s president. 

The Doomsday Clock was created in 1947, at a moment when nuclear brinkmanship between two superpowers kept the world permanently on edge. Today, the picture is far more complex. 

Multiple nations, corporations, and private labs are racing into fields once reserved for classified programs and black budget research. Technologies that barely existed a decade ago are now capable of destabilizing entire systems without a sound. 

Until 2020, the clock had never surpassed the two-minute mark. Now, only seconds remain. 

Daniel Holz, chair of the Bulletin’s Science and Security Board, noted that last year’s warnings produced not cooperation, but secrecy and escalation: “The opposite has happened.” 

Whether we actually cross the threshold is beside the point. The message in 2026 is unmistakable: the window is closing, and those who know aren’t waiting for public consensus. 

The only question now is whether this countdown remains symbolic or serves as advance notice before midnight arrives for real.

Created in 1945 by Manhattan Project Scientists, the 'Doomsday Clock' is a constant reminder of impending global catastrophe. In 2026, the clock ticked closer to midnight than ever before.
