"We were surprised by the streams of light that were visible near the center of the galaxies, as nothing similar has been ...

Hidden galaxies offering a glimpse into the past could reveal previously unknown secrets of the universe, challenging current models.

Languages: English. Despite appearing "dead"—i.e., forming no new stars—some red galaxies may secretly be alive, quietly birthing small stars under our noses. This is the conclusion of ...

Up until recently, astronomy was reliant entirely on electromagnetic waves. While that changed with the confirmation 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 ...

A new study reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This ...

Dwarf galaxies around the Milky Way, for example, either stopped forming stars billions of years ago, or have only recently begun forming them again after they entered our galaxy's sphere of ...

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 ...

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 like the Milky Way boast more than spirals; they also have feathers, where clumps of new stars are born. Astronomers have been stumped by how these complex structures form, but now a ...
