Life is complicated, and not just in a philosophical sense. But one simple thing we know about life is that it requires energy, and to get that energy it needs certain fundamental elements. A new paper in preprint on arXiv from Giovanni Covone and Donato Giovannelli from the University of Naples discusses how we might use that constraint to narrow our search for stars and planets that could potentially harbor life. To put it simply, if it doesn’t have many of the constituent parts of the “building blocks” of life, then life probably doesn't exist there.

Deep in the constellation Scorpius, about 3,400 light years from Earth, a spectacular cosmic butterfly is revealing fundamental secrets about how worlds like our own came to exist. Using the James Webb Space Telescope, astronomers have peered into the heart of the Butterfly Nebula and discovered clues that could transform our understanding of rocky planet formation.

The planet TRAPPIST-1e lies in its star’s Goldilocks zone, where water remains liquid – and an analysis suggests it might have a nitrogen-rich atmosphere like Earth’s
