What are the exact sizes of galaxies, and are they bigger than they appear in deep space images? This is what a recent study published in Nature Astronomy hopes to address as an international team of ...

A 3.5-gallon volume of deep space, specifically within the Milky Way's Orion-Cygnus Arm, would contain approximately 4 million neutrinos and about 13,000 gas atoms, predominantly hydrogen and helium.

The galaxy appears to have tentacle-like trails of gas and stars jutting off from one side, likely making it a jellyfish galaxy — a class of galaxies that drip tendrils of star-forming material as ...
