1. Thanksgiving feast in space!
Three of the six crewmembers aboard the International Space Station are from the United States, but on Thanksgiving, all were welcome to enjoy the feast. On Thursday (Nov. 23), the Expedition 53 crew planned on serving turkey, mashed potatoes, and candied yams!

2. InSight Mars Lander passes big test
The InSight spacecraft recently completed an important "thermal vac" test at the Lockheed Martin Space Systems facility in Littleton, Colorado. InSight is NASA's next Mars lander, and the testing, which was done in preparation of its scheduled May 2018 launch, was intended to simulate the harsh environment of space.

3. Earthly message travels towards life-friendly planet GJ 273b
An announcement on Thursday (Nov. 16) revealed that scientists and artists beamed up a message to a nearby red dwarf star known as Luyten's star. The message sent a month ago was intended for the star's two known planets, one of which might have conditions friendly to life.

4. Light pollution is on the rise
A new study revealed that more and more artificial light is filling Earth's night skies. Researchers came to their findings by using data from Earth-observing weather satellite, Suomi NPP. One of the many consequences of light pollution is the disruption of biological cycles that are triggered by variation of light, such as gene expression and ecosystem functions.

5. NASA reveals local glacier melting threats
NASA has released a free online tool that allows the public to view how sea level rise could adversely affect 293 different port cities. The tool offers regional predictions of how melting glacier ice may impact coastal communities in the near future.

6. Ultra-powerful new space telescope's science targets chosen
The Space Telescope Science Institute, which manages the new James Webb Space Telescope project, announced on Monday (Nov.13) the thirteen selected proposals for its first round of scientific observations. The programs, which include observations of Jupiter and extremely distant galaxies, will kick off when the telescope begins operations in 2019.

7. Sun experiences temporary atmospheric hole
Solar winds rushed out into space when a large opening developed recently in the sun's atmosphere. On Monday (Nov. 20), NASA's Solar Dynamics Observatory released an image of the coronal hole, which is produced by the sun's active magnetic field.

8. Interstellar Asteroid a Space Cigar!
Traveling at high speed from interstellar space, the strange object 'Oumuamua was originally thought to be an ancient comet, but observations revealed it was, in fact, an asteroid from another star system. And now, we know what 'Oumuamua looks like and the story got stranger: the interstellar interloper looks like a strange, elongated cigar and scientists are floored.

9. Titan's polar vortex explained
A new study may have uncovered the mystery behind the cold polar vortex of Saturn's moon, Titan. The largest of Saturn's more than 60 moons, Titan is the only one with a known atmosphere, and it's the atmosphere's unique chemistry that seems to be causing the cold whirling air above Titan's south pole.

10. Major earthquakes may erupt as Earth slows down
Earth experiences periodic changes in its rotation speed, and according to new research presented at the annual meeting of the Geological Society of America, the small slowdown in Earth's rotation may lead to more earthquakes in 2018. As many as 20 earthquakes with a magnitude of 7 or higher may occur along already stressed faultlines over the next four years, according to a geologist.

11. Amazon's Mercury 13 Space Series
A new miniseries is in the works to dramatize the true story of 13 women who underwent the same medical testing as the space age NASA astronauts. Amazon is basing the series on Martha Ackmann's 2003 book, "The Mercury 13: The True Story of Thirteen Women and the Dream of Space Flight" (Random House) and will center on the female pilots that made up the First Lady Astronaut Trainees (FLATs).

12. Streaks on Mars: New Theory
Liquid water may not be under the Martian surface after all, according to a new study. Researchers studied the dark streaks on Mars' hillsides, and now argue that sandy material is lumping together to produce the darker color, rather than the hypothesized underground supply of liquid water.
