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

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 ...

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 ...

LOFAR’s LoTSS-DR3 survey maps 13.7 million radio sources, revealing black hole jets, supernovas, galaxy clusters and new details about magnetic fields in the Milky Way and beyond ...

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 ...

New data confirm that the titanic collisions of galaxies ignite the most powerful active galactic nuclei. Active galactic nuclei (AGN) are phases in which supermassive black holes at the centre of ...

Astronomers have identified the most powerful and distant microwave laser, or maser, ever observed, originating from two ...

What happens when two rare ring galaxies collide? They form an infinity symbol—or the face of a cosmic owl, depending on how you look at it. The James Webb Space Telescope has helped two international ...

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 ...
