What a newly discovered gas bridge between galaxies tells us about the cosmic cycle of matter
New radio astronomy results reveal how galaxies exchange gas with the intergalactic medium – the raw material for stars and ...
Astronomers have been watching this galaxy pair, NGC 4532 and DDO 137, for years and discovered a "gas bridge" over 185,000 light years long.
Using the James Webb Space Telescope (JWST), scientists found that many galaxies started as thick discs before forming the thin discs we see now. This discovery helps answer a long-standing mystery ...
Dark matter plays a crucial role in galaxy formation by acting as a gravitational “glue” that helps pull gas together to form ...
