Earth has a big beautiful Moon, while Venus, its 'sister planet', doesn't. Why is that? Did it ever have one? If it did, new research shows it was never going to last very long.

More good news for NASA's Nancy Grace Roman Space Telescope. The telescope's first mid-course correction was extremely efficient, using only 10% of the fuel allotted for it. This efficiency, coupled with other factors, means the powerful space telescope will likely have an additional ~12 years of observing time.

Astronomers used 8 years of observations to create a 3D image of a very young, very massive binary star as it forms. The image shows that the disks in the system are all misaligned. Those misalignments, together with the orbit, are clues to the system's chaotic history.

Our Sun is the very reason life exists on our small, blue planet. It provides solar radiation that warms the planet and ignites the intricate biochemical processes like photosynthesis producing oxygen for life to breathe. However, while the Sun is known for giving life, it can also potentially take it away with its solar flares, geomagnetic storms, and solar radiation storms, all of which are referred to as space weather. But how can space weather be forecasted so industries can better prepare and protect their assets, including Earth infrastructure, satellites, and even human safety?

Bezos said we should move heavy industry to the Moon. Musk says we'll have sustainable lunar cities. We know there's ancient water ice in craters on the Moon's poles, but there's not enough water to support a city.

A new study led by researchers from Caltech demonstrates the effectiveness of Fast Radio Bursts (FRBs) as a tool for measuring cosmological distances and the clustering of matter.

Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has been focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That creates a huge “synchronicity” problem - what if there aren’t any alien civilizations broadcasting radio signals now, but there were a billion years ago? The Milky Way is around 13 billion years old - hoping that we exist at the same time as an alien civilization that happens to be actively messaging is a huge leap of faith. But, according to a new paper available in pre-print on arXiv and submitted to the International Journal of Astrobiology by Lewis J Pinault, as associated researcher at the SETI Institute, and his co-authors, we could take a completely alternative approach to trying to find alien civilizations - by looking for evidence of them in lunar dirt.
