An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea to help reconstruct a slow-motion cosmic collision, one that has been ...

The researchers believe the direct collision occurred a few hundred million years ago and that the two clusters are now ...

The Hubble Space Telescope has discovered evidence that our galaxy experienced a significant collision and merger with a dwarf galaxy 11.8 billion years ago. Mergers between galaxies are one of the ...

Astronomers think that some 10 billion years ago, our Milky Way galaxy collided with another galaxy, which they’ve dubbed the Gaia Sausage. And on July 21, 2026, a team of astronomers at the Royal ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

The Small Magellanic Cloud or the SMC is one of the Milky Way's closest galactic neighbors – a small, gas-rich galaxy visible to the naked eye from the southern hemisphere, bound to our galaxy by ...

The team used a one-of-a-kind instrument on CFHT called SITELLE, which can capture incredibly detailed views of entire galaxies all at once. “Understanding what’s happening during these collisions is ...
