Caltech researchers have identified a novel chemical reaction that could explain the formation of the building blocks of DNA and RNA, the molecules that encode all of life’s functions. The work is an important step toward understanding how life may have emerged...
Debris is still raining down on Earth more than 100 million years after the giant cosmic explosion that created it. A study published this week in Nature Astronomy by an international team reached this conclusion using measurements of rare isotopes within a...
A team of astronomers, led by Brooke Kotten of the University of Michigan, has shown that TOI-5882—a sunlike star located some 1,300 light-years away—has likely eaten one of its planets. Go to Source
Saturn’s largest moon, Titan, is a unique environment in our solar system. It is the only moon (or body beyond Earth) to have a dense, nitrogen-rich atmosphere, and its methane cycle is very similar to Earth’s hydrological cycle, in which solid and liquid...
