The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports. The team has shown ...

The James Webb Space Telescope’s first picture released to the public showed off thousands of galaxies. At first glance, the pinpoints of light shining in the blackness of space look like little stars ...

In research published today, Australian scientists have taken a critical step towards understanding why different types of galaxies exist throughout the universe. The research, made possible by ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...

The vastness of space allows for a huge variety of structures to pop up all over the place. Even things we think of as one-and-done objects—like galaxies—come in quite a few shapes and sizes. Follow ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered ...

Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the ...

Edwin Hubble, born November 20, 1889, made seminal observations in 1923 of the Andromeda Galaxy and a Cepheid variable, which significantly broadened the understanding of other galaxies and the ...
