New analysis of Hayabusa2 data of the asteroid Ryugu reveals much of the surface reflects and scatters light in ways that are consistent with studies of carbonaceous chondrite meteorites in the lab.

A rock retrieved from a near-Earth asteroid is crawling with microbial life, scientists have discovered. But the bacteria on its surface almost certainly came from Earth. The sample is part of a ...

SwRI scientists reviewed spectral data of sample material taken from near-Earth asteroids Ryugu and Bennu (pictured above) and compared them with spectral data of main belt asteroid Polana from the ...
