A mammoth star explosion known as SN2016aps, which occurred in a galaxy about 3.6 billion light-years from Earth, is the brightest "We can measure supernovae using two scales: the total energy of the explosion, and the amount of that energy that is emitted as observable light, or radiation," study lead author Matt Nicholl, a lecturer in the School of Physics and Astronomy and the Institute of Gravitational Wave Astronomy at the University of Birmingham in England, said in a statement. "In astronomy, seeing things further away means looking back further and further in time. The original object, called the progenitor, either collapses to a neutron star or black hole, or is completely destroyed. Credits: NASA.

The supernova was photographed by NASA's Near Earth Asteroid Tracking system on Feb. 18. On the right is the star before it exploded. For example, the team determined that much of SN2016aps' brightness probably derived from the interaction between the supernova and a surrounding shell of gas. "We think this is one of the most compelling candidates for this process yet observed, and probably the most massive. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.
"SN2016aps is spectacular in several ways," co-author Edo Berger of Harvard University said in a Scientists detected high levels of hydrogen gas in the explosion, leading them to believe the star formed from two less massive stars merging together, since lower mass stars hold onto hydrogen for longer. A supernova is a powerful and luminous stellar explosion. Get the latest breaking news delivered straight to your inbox.Copyright © 2020 CBS Interactive Inc. All rights reserved. Now we know what to look for. They determined it occurred in a relatively small galaxy "in the middle of nowhere," approximately 4.6 billion light-years from Earth. Scientists weren't even able to see where the star was born until after the The explosion is extremely rare, categorized as a "superluminous" supernova. The images captured the star's appearance just a few weeks after the ancient explosion occurred. This is the most light we have ever seen emitted by a supernova.

"The new study, which was published online today (April 13) in the journal "Finding this extraordinary supernova couldn't have come at a better time," co-author Edo Berger, an astronomy professor at Harvard University, said in the same statement.
"SN2016aps is so odd and so extreme that Nicholl and his colleagues think it may be a "pulsational pair-instability" supernova, in which two big As its name indicates, SN2016aps was discovered in 2016, by the Panoramic Survey Telescope and Rapid Response System in Hawaii. The new space telescope will conduct a wide range of observations, from studying the formation of the universe's first stars and galaxies to hunting for signs of life in the atmospheres of nearby alien planets.For a limited time, you can take out a digital subscription to any of Stay up to date on the coronavirus outbreak by signing up to our newsletter today.Thank you for signing up to Live Science. Shown in orange is the calcium-rich material created in the explosion. They said that the observance of SN2016aps could lead to more discoveries of similar supernovae from a relatively unknown period of cosmic history. NY 10036. Astronomers have spotted a record-breaking supernova — the largest ever observed. "If the supernova gets the timing right, it can catch up to this shell and release a huge amount of energy in the collision," Nicholl said. "One explanation is that two slightly less massive stars of around, say 60 solar masses, had merged before the explosion. "In addition, the researchers calculated that the supernova system harbored between 50 and 100 times the mass of "The gas we detected was mostly hydrogen — but such a massive star would usually have lost all of its hydrogen via stellar winds long before it started pulsating," Nicholl said. The explosion energy of SN2016aps, fueled by the shedding of a massive shell of gas, was ten times that of a normal-sized supernova, making SN2016aps the most massive supernova ever identified. Supernova Explosion Seen In Nearby Galaxy | Video - YouTube "The nature of those first stars is one of the big questions in astronomy," Nicholl said. Future US, Inc. 11 West 42nd Street, 15th Floor, Due to its intense energy output, scientists believe that, at birth, the star had a mass of "at least" 100 times that of our sun. Artist’s interpretation (without labels) of the calcium-rich supernova 2019ehk. You will receive a verification email shortly.There was a problem. Nicholl and his team tracked the event for two years with NASA's These observations allowed the researchers to characterize the explosion and piece together how it may have happened.
