Image of the irregular dwarf galaxy Sextans A, located at a distance of about 4 million light years from us, towards the edge of the Local Group, captured by the VST (VLT Survey Telescope), an Italian ...

At approximately 100,000 light years in diameter, the Milky Way’s vastness and the broader, ever-changing dynamics of the cosmos defy any attempt to fully understand our home galaxy and its history.

Discover how JWST's groundbreaking observations of the oldest galaxies reveal new insights into early galaxies discovery and transform our understanding of galaxy formation.

A dwarf galaxy 100 million light years away is being stripped of its crucial star-forming gas, and it seems that the cosmic ...

The Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope took this image of NGC 1433, a barred spiral galaxy with a particularly bright core surrounded by double star-forming rings. The ...

A new photograph shared by NASA offers a peek at the breathtaking views seen from the International Space Station (ISS). The image shows off Earth's colorful airglow as well as two nearby galaxies, ...

Scientists used the James Webb Space Telescope to study the unusual star-forming timeline of dwarf galaxy Leo P. Most small galaxies that stopped making new stars in the early universe never resumed ...

For decades, scientists have known that some galaxies reside in dense environments with lots of other galaxies nearby. Others drift through the cosmos essentially alone, with few or no other galaxies ...

See amazing views of the M74, NGC 7496, IC 5332, NGC 1365, and NGC 1433 galaxies captured using the James Webb Space ...

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 ...

The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, ...
