Comets may be a key source for the building blocks of life, but the only planetary systems where those ingredients could survive impact may be ones with large stars or lots of neighbouring worlds
Scientists suspect that comets may have delivered the key ingredients for life on Earth, and new research outlines how exoplanets could have received these deliveries, too.
Cambridge researchers propose that comets could transport life's building blocks to other planets, especially in ‘peas in a pod’ systems. Their findings suggest that these molecules can survive on planets with closely orbiting neighbors, offering new insights into the search for extraterrestrial lif
Packed “peas in a pod” planetary systems could slow a comet through a game of gravitational pinball to enable a delivery of chemical building blocks for life, Cambridge researchers said.
