The UAE’s first interplanetary mission could help solve the mystery of what happened to the Martian atmosphere.

Harvard Astronomer Avi Loeb thinks the astronomical research community needs to get with the program and refocus its efforts on finding and identifying intelligent life in the cosmos.

Researchers said Wednesday they had observed water vapour escaping high up in the thin atmosphere of Mars, offering tantalising new clues as to whether the Red Planet could have once hosted life.

NASA’s rover must plow through Mars’ atmosphere at supersonic speeds, deploy a parachute to slow itself, then fly to safety with a jetpack.

A Chinese spacecraft appears poised to enter orbit around Mars, one day after an orbiter from the United Arab Emirates did so and about a week ahead of an American attempt to put down another spacecraft on the surface of the red planet.

The UAE’s orbiter reaches Mars on Tuesday, followed less than 24 hours later by China’s orbiter-rover combo. NASA’s Perseverance rover is due to land on February 18.

Recalibrated Betelgeuse’s mass, radius, and distance. Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020 (Figure 1), which has prompted speculation that Betelgeuse may be about to explode.
