The space telescope's image of a odd-looking spiral galaxy is, in reality, two distant galaxies overlapping each other.

It challenges what we know about how galaxies form. Picture a galaxy like our own Milky Way: a flat, rotating structure made up of stars, gas and dust, often surrounded by an extensive halo of ...

Galaxies die earlier than expected Date: April 2, 2025 Source: Université de Genève Summary: For a long time, scientists thought that only actively star-forming galaxies should be observed in ...

Developed by Israeli scientist Mordehai Milgrom in the 1980s, MOND postulates that galaxies form and expand much quicker under a stronger force of gravity than the standard model accounts for. The ...

Our new study of the nearby starburst galaxy Haro 11 has shown that strong X-ray-emitting superwinds may be a key mechanism ...

Understanding them helps scientists test how galaxies form, evolve, and gather stars over time. Dwarf galaxies usually have a total stellar mass of less than one billion suns. That’s a fraction ...
