Mars

Join us this week as we talk with scientists about the Perseverance rover and what we will discover about life on Mars from its exploration.

Thiophenes are compounds of carbon, hydrogen, and sulfur. Their molecules contain a ring of four carbon atoms and one sulfur atom. They are found in coal, crude oil, in fossils of microscopic life, and bacterial mats.

It might sound odd, but scientists think Mars is going to have a ring around it in tens of millions of years. They're predicting that one of Mars' moons, Phobos, is going to break apart, and its particles are going to make a ring around Mars.

Although the Mars rovers Spirit and Opportunity found geological evidence that ancient Mars had standing liquid water a long time ago, scientists are now talking about water on Mars again.
