Astronomers have spotted a star around 160,000 light years away that appears to have exploded twice in the first ever evidence of a "double supernova". A supernova is a powerful stellar explosion that ...

The ESO's Very Large Telescope points at the exact position of the supernova remnant SNR 0509-67.5, or "the expanding shells of a star that detonated twice," located in the Large Magellanic Cloud, a ...

"This tangible evidence of a double detonation not only contributes towards solving a long-standing mystery, but also offers a visual spectacle." When you purchase through links on our site, we may ...

A pair of rare, compact white dwarf stars that are set to collide in about 23 billion years have been spotted by researchers at the University of Warwick. After converging, the binary star system will ...

A long-forgotten star has shared a final, spectacular secret. Hidden in its dusty remains, astronomers have found clues showing it exploded not once, but twice. The finding comes from SNR 0509-67.5, a ...

A strange flash in a distant galaxy first looked like a familiar kind of stellar wreckage, the radioactive afterglow of ...

A strange double flash in a distant galaxy may be the first glimpse of a “superkilonova,” a cosmic one‑two punch that fuses two of the most violent stellar deaths known. Astronomers watched a massive ...

Stellar explosions are messy affairs, so two consecutive supernovas in the same galaxy are bound to leave a mark. That's the story behind a dramatic new Hubble Space Telescope image of a galaxy called ...

Supernova 2007ck (left) is a Type II event, and Supernova 2007co (right) is a Type Ia event. The image is a combination of red, green, and blue pictures taken on June 9 and 12 by the ...

In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring ...

Generally speaking, once a star explodes, that’s pretty much it. It’s done. But there are exceptions. In the 1870s, the star Eta Carina underwent a massive and violent outburst, releasing so much ...
