New observations show a star that blew up in two separate bursts, confirming a long-suspected cosmic phenomenon called a ...

Astronomers have discovered a giant, 500-light-year-wide cavity between two star-forming regions in the constellations Perseus and Taurus. An ancient supernova could be the culprit.

The most recent nearby supernova, SN 1987A, was in the Large Magellanic Cloud. The Milky Way’s youngest known supernova is called G1.9+0.3.

The Milky Way's youngest known supernova remnant is a radio source called G1.9+0.3. The remnant, which lies 27,700 light-years away, is only about 140 years old.

Placing the Milky Way’s uniqueness, or lack thereof, in a broader context is crucial because, for decades, scientists have used it as a model to understand how galaxies form and evolve.

Astronomers have discovered a strange new object in our Milky Way galaxy. The celestial object is emitting X-rays around the same time it's shooting out radio waves.

In roughly 4 billion years, our home Milky Way galaxy may collide with the neighboring Andromeda galaxy. We are approaching Andromeda at roughly 250,000 miles per hour, and scientists have ...

The LMC supernova wreckage MC SNR J0519–6902 as seen by the ATCA (Image credit: Alsaberi et al/arXiv 2025) Cosmic vampire blows its top. White dwarfs are the stellar corpses that are created ...

Researchers have used machine learning to dramatically speed up the processing time when simulating galaxy evolution coupled with supernova explosion. This approach could help us understand the ...

Milky Way will be visible in May, over Memorial Day weekend, across US: When to see our galaxy Billions of stars comprising the Milky Way, our home galaxy, should appear especially vibrant till ...

A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, it could hinge on the flip of a cosmic coin.

Astronomers thought the Milky Way was doomed to crash into Andromeda. Now they're not so sure. by Ruby Wright, Alexander Rawlings, The Conversation ...
