University of Missouri researchers have uncovered evidence that challenges one of astronomy's most trusted assumptions, a ...

Known as IC 1101, the galaxy’s diameter is estimated to be a whopping 520 kiloparsecs, or nearly 1.7 million light-years, researchers report in a study submitted July 16 to arXiv.org. That’s wider ...

Astronomers have released the largest two-dimensional map of the universe ever created.

Hold on to your telescopes: The DESI Legacy Imaging Surveys team has released the largest-ever 2D color map of the universe. The 5.6-trillion-pixel map contains nearly 4 billion celestial objects, ...

Astronomers just published the largest two-dimensional map of our universe - and it's breathtaking.

The observatory recently began its 10-year survey of the southern sky using the world's largest digital camera.
