A flat plane of dark matter beyond the Local Group may explain why nearby galaxies move away from us instead of falling ...

We live in a dark, dark, world. The post Our Entire Galaxy Appears to Be Embedded in a Colossal Sheet of Dark Matter appeared ...

Astronomers have uncovered evidence that the Milky Way is not drifting through space alone but is embedded in a vast, flat structure of dark matter stretching tens of millions of light-years. The ...

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.

Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from ...

The latest data release from the Sloan Digital Sky Survey (SDSS) includes observations revealing the internal structure and composition of nearly 5,000 nearby galaxies observed during the first three ...

NGC 300 is a small galaxy in a relatively isolated region of the universe. About 6 million light-years from Earth, it is one of the Milky Way's closer neighbors. A team of astronomers led by ...

A group of galaxies in our cosmic backyard has given astronomers clues about how stars form. A thorough survey using the NASA/ESA Hubble Space Telescope has observed around 14 million stars in 69 ...

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 ...

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, ...

Observations of a galaxy from an early period of the Universe’s history reveal a bar-shaped structure and gas dynamics thought not to have been possible at that time. In broad brushstrokes, galaxies ...

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 ...
