The Hubble Space Telescope saw a galaxy that has features of both elliptical and spiral galaxies, puzzling experts.

The star-forming region called Sagittarius B2 contains half of the galactic center's stars, yet only 10% of the gas.

Behind the dusty clouds of the Cigar Galaxy lies a dazzling powerhouse of star formation, where stars are being born ten ...

For several years, the astronomers have been intrigued by the compact and luminous galaxies observed in great number in the remote Universe. They are dwarf by their sizes, and however radiate ten to ...

"To make progress towards a theory of galaxy formation, it is crucial to compare results and codes from different simulations. We have now done this by bringing together competing code groups behind ...

Sometimes, Hubble or other telescopes will capture two or more galaxies that are in the process of merging — called interacting galaxies. These huge collisions can warp one or both of the galaxies, ...

An international team led by the University of Geneva (UNIGE) has identified three ultra-massive galaxies—nearly as massive as the Milky Way—already in place within the first billion years after the ...

This illustration provided by the European Southern Observatory in February 2024, depicts the record-breaking quasar J059-4351, the bright core of a distant galaxy that is powered by a supermassive ...

Metallicity distribution of the first supernovae at 10 million years after the explosion. The supernova ejecta (orange region) has expanded to a radius of 1 kpc and enriched the surrounding gas to ...

"We know these monster black holes exist at the center of galaxies near our Milky Way, but the big surprise now is that they were present at the beginning of the universe." When you purchase through ...

New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.
