March 21 (UPI) -- Scientists have discovered some of the building blocks of life in samples recovered from the Ryugu asteroid. The discovery lends credence to the idea that many of the important chemicals that formed life on Earth came from outer space, researchers say.

 

The sample was collected by the Japanese Space Agency's Hayabusa2 spacecraft in 2018 and returned to Earth in 2020.

 

The samples are the oldest scientists have been able to study in a lab, as they predate the full formation of Earth and offer clues into the kinds of chemicals that were being seeded onto the planet in its primordial phase.

This is interesting.  I wonder if it means that the building blocks of life actually exist on other planets and accidentally ended up here?  Where did the asteroid actually originate?
