Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...

In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely ...

Situated around 17,000 light-years from Earth within the Milky Way Galaxy, the supernova remnant is close enough for NASA’s ...

The powerful gravity of a galaxy embedded in a massive cluster of galaxies in this Hubble Space Telescope photo is producing multiple images of a single distant supernova far behind it. Both the ...

Astronomers say they've captured the clearest look yet of a star on the brink of supernova. An international team used NASA’s James Webb Space Telescope to backtrack and find the original star that ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn.

Nasa. LARGE FORMAT. HUBBLE telescope. Here, in the rubble of a supernova explosion, HUBBLE highlights a neutron star pushed out of the center of the nebula. Vintage chromogenic print. Numbering in the ...

The main image at left shows a combined Webb and Hubble view of spiral galaxy NGC 1637, with the region of interest in the top right. The remaining three panels show a detailed view of a red ...
