Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

Astronomers have used the LOFAR telescope array to create the largest radio survey of the cosmos, revealing 13.7 million ...

CNN — A new telescope image showcases two entangled galaxies that will eventually merge into one millions of years from now -- and previews the eventual, similar fate of our own Milky Way galaxy. The ...

Three supermassive black holes igniting at once in a single system is one of the most extreme feeding frenzies the universe can stage, and recent observations show that this is happening during a rare ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Last month when scientists announced new ...

Astronomers have used powerful adaptive optics technology at the W. M. Keck Observatory in Hawaii to reveal the precise locations and environments of a pair of supermassive black holes at the center ...

For the first time, astronomers have been able to combine the deepest optical images of the universe, obtained by the Hubble Space Telescope, with equally sharp images in the near-infrared part of the ...

Examples of merging galaxies containing a heavily obscured growing supermassive black hole observed by the Hubble Space Telescope. The top panels show nearby galaxies at ~500 million light-years from ...

When the venerable Hubble Space Telescope made its Deep Fields studies of the early Universe, it discovered something that would puzzle astronomers to this day. When the Universe was just a few ...
