Supernova 1987A: & # 39; blob & # 39; hides the long-awaited remnant before the starburst

Image copyright NASA / ESA / R.Kirshner et al. Caption This image of the Hubble Space Telescope shows Supernova 1987A in the large Magellanic Cloud Scientists believe they have finally tracked down the dead remnant of Supernova 1987A – one of their favorite starbursts. Astronomers knew that the object had to exist, but always had difficulty determining its location because …

NASA watched a wild supernova, but what she discovered was even stranger

While observing a large supernova in the "Fireworks" galaxy, researchers inadvertently took pictures of a short, bright spot in the same galaxy that is not from the supernova. This spot was not visible at the first observation of NASA NuSTAR, but was spied just over a week later during a follow-up by the Chandra X-ray Observatory of the Space Agency. …

Supernova remnants found in Antarctica could be 20 million years old

A star collapses at death, spitting space dust into a huge cloud of elements that make for very nice Hubble telescope photos. The "explosion", called supernova, leads either to a black hole or to a small, dense star, which no longer generates heat. A supernova also shoots space dust that wanders through the universe and occasionally comes in contact with …

This tremendous supernova was unlike anything seen before

Astronomers have observed a supernova that has never been seen before, and it could be a strong indication of a major type of star death that would have shaped early galaxies. The SN2016iet supernova does not fit with the classification schemes that scientists use today for supernovae. It looks like a "paired instability supernova" that would occur under the heaviest …

This is the most brutal supernova in history

Great Boom Scientists believe that they have witnessed the explosion of the most massive star ever detonated into a supernova Years of analysis and follow-up to understand what they had seen [CNN] , This is because SN2016 was completely at odds with the scientists' understanding of how supernovae should behave. Misfire The gigantic supernova lasted longer and gave off more …

A massive star completely destroyed by a supernova puzzles scientists

Supersupernova SN2016iet has released a tremendous amount of energy when it exploded, and it took a long time for it to fade. This and other details let astronomers suspect that this is a rare example of a pair instability supernova. When massive stars explode, they usually leave something – either a dense nucleus called a neutron star or a black …

Scientists were stunned after discovering the record-breaking supernova BGR

Scientists handle the lifecycle of various stars quite well. They know the kinds of stars that are likely to die in fiery supernova explosions, and they know that not all supernova are created equal. Nevertheless, space holds many unresolved secrets, and a new study published in The Astrophysical Journal shows that scientists had questioned their understanding of the supernova after …

A massive star completely destroyed by a supernova puzzles scientists

Supernova 2016iet is an example of one of the most extreme types of stellar explosions, though it has some strange features. (Source: Gemini Observatory / NSF / AURA / Illustration by Joy Pollard) In November 2016, the sharp-eyed Gaia spacecraft discovered a supernova that exploded several billion light-years from Earth. The astronomers followed with more telescopes and quickly realized that …
