Astronomers have detected the first true sugar molecule in the space between stars — a four-carbon compound called erythrulose — and its presence narrows one of origin-of-life research's most ...

Astronomers can use telescopes to find specific molecules in the atmospheres of neighboring planets, in nebulae – clouds of interstellar dust and gas – hundreds or thousands of light-years away, or in ...

The universe is 13.8 billion years old—and like many things that have been around for a while, it’s collected lots of dust. And just one of these dust particles could seed an entire planet. After a ...

This episode features a wide-ranging interview with the astrochemist Ewine van Dishoeck, who is professor emeritus of molecular astrophysics at Leiden Observatory in the Netherlands. In 2018 she was ...

If you were able to catch the last webinar from our Chemical Sciences Roundtable, “Chemistry in 2050– Space” you know that it was out of this world, literally and figuratively. The webinar explored ...
