Scientists have used artificial intelligence to spot small, newly formed craters on Mars for the first time.
Why it matters: This use of AI could cut down on the time scientists spend combing through images of the Red Planet's surface taken by orbiters to find interesting features worthy of study.
Three scientists are sharing the Nobel Prize in physics this year for their work on the supermassive black hole at the center of the Milky Way.
Why it matters: The laureates — Roger Penrose, Reinhard Genzel and Andrea Ghez — have created a more full theoretical and observational view of the inner workings of our galaxy.
China has chosen a new class of 18 astronauts, another step along its methodical path to explore space in the coming decades.

Three scientists — Harvey J. Alter, Michael Houghton and Charles M. Rice — have won the Nobel Prize for their discovery of the Hepatitis C virus, a blood-borne liver disease that infects millions every year.
Why it matters: Before the scientists' discovery, many liver problems went unexplained. "The discovery of Hepatitis C virus revealed the cause of the remaining cases of chronic hepatitis and made possible blood tests and new medicines that have saved millions of lives," the Nobel Prize committee said.
