The video ranks the biggest cosmic threats to humanity, from rogue planets and black holes to supernovas, gamma ray bursts, ...

Why is the Andromeda Galaxy moving toward us while other neighboring galaxies are speeding away? For decades, such galactic movements have puzzled astronomers. Now, computer simulations by Ewoud Wempe ...

More recent work, however, casts doubt on the certainty that the two galaxies will clash, eventually forming a single, ...

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a ...

As a galactic archaeologist, my job is to reconstruct the past of our galaxy – and read the signs of its future.

A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring ...

A newly confirmed dwarf galaxy orbiting Andromeda contains so few stars that automated detection pipelines ignored it entirely — and that invisibility may be precisely what makes it scientifically ...

Published in the Monthly Notices of the Royal Astronomical Society, the study analyses, using simulations, how galaxy collisions can completely or partially destroy stellar discs. Together with ...

No matter the time or vantage point, from a pre-Neolithic cave to a post-lockdown London high-rise, the predictability of the night sky has always been humanity's symbol of permanence and reassuring ...
