Scientists have given the all-clear to Earth from a newly discovered asteroid.
After two months of observations, scientists have almost fully ruled out any threat from the asteroid 2024 YR4, NASA and the European Space Agency said.
Japanese scientists have confirmed a monumental discovery: asteroid Ryugu contains all 5 nucleobases essential for DNA and RNA. By analyzing 5.4 grams of material returned by the Hayabusa2 spacecraft, researchers identified adenine, guanine, cytosine, thymine, and uracil in similar proportions.
