A Previously Unseen Chemical Reaction Has Been Detected on Mars

Posted by in categories: chemistry, particle physics, space

The giant Martian sandstorm of 2018 wasn’t just a wild ride — it also gave us a previously undetected gas in the planet’s atmosphere. For the first time, the ExoMars orbiter sampled traces of hydrogen chloride, composed of a hydrogen and a chlorine atom.

This gas presents Mars scientists with a new mystery to solve: how it got there.

“We’ve discovered hydrogen chloride for the first time on Mars,” said physicist Kevin Olsen of the University of Oxford in the UK.

Study of Supergiant Star Betelgeuse Unveils the Cause of Its Pulsations – Not at All Close to Exploding

Posted by in category: space

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.
