How life on Earth first arose is one of the most profound mysteries of science, and evidence is mounting that the key building blocks may have been delivered to our home planet from space. A new study ...

NASA's OSIRIS-REx mission found ingredients for DNA and RNA on the asteroid Bennu. The discovery shows asteroids could seed planets with the precursors for life. It's also more evidence that life ...

NASA-funded researchers have evidence that some building blocks of DNA, the molecule that carries the genetic instructions for life, found in meteorites were likely created in space. The research ...

A fresh examination of meteorites that landed in the United States, Canada and Australia is bolstering the notion that such objects may have delivered to Earth early in its history chemical ...

A trio of unique meteorites show evidence for fundamental building blocks of life, two of which astronomers had not previously identified in space rocks. In a new paper published Tuesday in the ...

Researchers have moved closer toward this goal by developing a nanopore sequencing platform that, for the first time, can detect the presence of nucleobases, the building blocks of DNA and RNA.

NASA probed an asteroid and found an ancient repository of ingredients for life. The findings, published in two papers in the journals Nature and Nature Astronomy on Wednesday, point to a missing link ...
