The new work was less notable for showing that we had found these bases in Ryugu than for solving a previous mystery: earlier studies had failed to detect them there, despite their presence in many other asteroid samples.

1 month agoAliens could be CATAPULTED onto Earth via an asteroid, study claims
We found that life is more likely to survive an asteroid impact, so it's definitely still a real possibility that life on Earth could have come from Mars. Maybe we're Martians! The idea that life could have spread through the solar system or even the universe on rocks is known as the lithopanspermia hypothesis.

1 month ago'Planetary parade' will see SIX planets align in rare spectacle
Chances to see 4 bright planets with your own eyes occur every few years on average, so it's not once in a lifetime. Even so, the planets are best observable just after sunset, so this is one of the most convenient opportunities for several years.

2 months agoScientists Intrigued by Unfamiliar Life Form
It's a plant! It's a fungus! It's... an entirely new type of lifeform hitherto unknown to science? That appears to be the case for a puzzling, spire-shaped organism that lived over 400 million years ago, according to a new study published in the journal Science Advances. After analyzing its internal structures, the authors argue that the mystifying ancient beings known as prototaxites don't belong to any of the existing biological kingdoms.
