The Milky Way's satellite galaxies are less typical than previously thought. Most Milky Way-like galaxies have star-forming satellite galaxies, unlike our own. The Milky Way's unique satellite galaxy ...

When looking up at the sky, you might think galaxies have always looked the way they do today. But a new study from Princeton University and published in the journal, Monthly Notices of the Royal ...

The James Webb Space Telescope may have discovered Population III stars, the universe's first generation of stars. They may tell us more about how galaxies form. When you purchase through links on our ...

A whole universe of hidden galaxies lies just beyond what the eye can see. Thanks to a new generation of space telescopes, astronomers are now revealing these distant, dim worlds—some no bigger than a ...

Understanding the gas from which stars form is a fundamental goal in astrophysics. This is a pressing issue for pristine galaxies — those low in heavy elements, known as metals — whose growth remains ...

The red shade shows the atomic hydrogen gas content of the galaxy, overlaid on the optical image. The atomic gas that is outside the white circle does not contribute significantly to the formation of ...

A surprisingly mature spiral galaxy named Alaknanda has been spotted just 1.5 billion years after the Big Bang—far earlier than astronomers believed such well-structured galaxies could form. With ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...

The Large and Small Magellanic Clouds are irregular dwarf galaxies and satellites of the Milky Way. The LMC is about 163,000 light-years away and the SMC is about 206,000 light-years away, and their ...
