Webb reveals a bridge of stars linking two nearby dwarf galaxies, offering a look at how gravity reshapes galaxies and sparks ...

An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion ...

Measuring the energy of hot gas within a remote group of galaxies reinforces the importance of giant black holes in forming ...

Using data from the James Webb Space Telescope, astronomers traced how Milky Way–like galaxies formed and changed over time.

Look up at the night sky and it is easy to believe that stars and galaxies are where the universe keeps almost all of its ...

The scorching cloud of gas threaded between clusters of galaxies is five times hotter than current models predict, ...

Gas cloud collisions during galaxy mergers compress interstellar material, triggering new star formation, as observed in interacting systems studied by NASA and reported by Universe Today.

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

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.

Across the observable universe, galaxies advertise themselves in radio waves for familiar reasons-magnetic fields, cosmic ...

Images taken using the Hubble Space Telescope have given astronomers clues about the formation and growth of the first galaxies, suggesting that early star formation happened in violent bursts. A team ...
