In 1181, a supernova explosion appeared in the night sky for 185 days. Historical records show that the supernova, which some witnesses said looked like a "temporary star," shined as bright as Saturn in the constellation Cassiopeia.
Scientists using the James Webb Space Telescope (JWST) have made a monumental discovery, finding evidence for a neutron star at the heart of a young supernova remnant.
Not to be outdone by the James Webb Space Telescope and its beautiful new nebula image, the Hubble Space Telescope delivered a pair of fresh new space photos this week.
The largest supernova seen in over a decade just exploded (from the perspective of observers on Earth), and one lucky photographer managed to capture it in a before-and-after sequence of photos.
The James Webb Space Telescope has captured what is known as a Wolf-Rayet star, the brief phase that comes just before it goes supernova. Due to how short the time is that a star is in this phase, it is one of the rarest astronomical observations.
A supernova witnessed by Chinese astronomers in the year 185 A.D. has been captured by the Dark Energy Camera telescope.
Astrophotographer Andrew McCarthy has captured a star that went supernova back in the medieval period.
The most powerful gamma-ray burst ever observed that released 18 teraelectronvolts of energy has been captured by orbiting telescopes.
A team of astronomers used three NASA space telescopes to create a composite image of the remains of a supernova that reveals details about the star's death.
A new image taken by the Hubble Space Telescope showcases a spiral-shaped galaxy that lies around 150 million light-years away. But NASA says not to be fooled: its peaceful state belies a violent past.
Astrophotographer Matt Harbison spent six months in a desert observatory in order to create a massive 700-megapixel 12-panel photo of the Cygnus Loop and Sadr region of space, which includes the remnants of an exploded star.
In celebration of the Hubble Space Telescope's 31st year, NASA astronomers aimed the famed observatory at what is called a "celebrity star," or one that is one of the brightest in our galaxy. This one, named AG Carinae, is wavering on the edge of self-destruction.
NASA has just published a stunning, one-of-a-kind time-lapse captured by the Hubble telescope. The short video shows an exploding star (AKA a supernova) in a galaxy 70-million light-years from Earth—a fireworks show so bright it outshone every other star in its galaxy before fading into oblivion.
Back in February, photographer Jason Guenzel began photographing a particular galaxy in the sky on moonless nights. Then in early May, he captured something unexpected and extremely rare: a star exploding, or the birth of a supernova.
Back on September 20th, 2016, an Argentinian amateur astronomer named Victor Buso was setting up and testing a new camera on his telescope when he captured something that may have never been caught on camera before: the first moments of a supernova.
Astronomers have captured the first photo of a single supernova showing up in four different places of a single image due to a phenomenon known as gravitational lensing. The "lens" in this case was a massive galaxy that is capable of using its gravity to bend and magnify light.
