Amidst the coronavirus pandemic, which basically put Earth on hold, experts are focused on the skies. An enormous star explosion could be the biggest one ever seen.
The star explosion known as SN2016aps, which occurred in a galaxy about 3.6 billion light-years from Earth, seems to reportedly be the brightest supernova ever seen, according to the latest reports.
“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 stated.
Nicholl continued and said, “In a typical supernova, the radiation is less than 1 percent of the total energy. But in SN2016aps, we found the radiation was five times the explosive energy of a normal-sized supernova. This is the most light we have ever seen emitted by a supernova.”
NBC News revealed that this is so strange and extreme at the same time that Nicholl and colleagues reportedly believe that this may be a pulsational pair-instability supernova – two massive stars merge before the system explodes.
This kind of events is hypothesized, but it’s been revealed that astronomers have never confirmed their existence “observationally.”
The explosion was discovered in 2016
This one mentioned above was reportedly discovered back in 2016 by the Panoramic Survey Telescope and Rapid Response System in Hawaii.
Experts have been tracking this event for two years with NASA’s Hubble Telescope and more instruments.
Such observations turned out to be really helpful as they allowed researchers to analyze the explosion and characterize it and the way in which it might have happened.
It’s also important to note the fact that before the explosion, doomed enormous stars will experience some extremely violent pulsations.
NBC News cited Nicholl once more who said, “If the supernova gets the timing right, it can catch up to this shell and release a huge amount of energy in the collision.”
He concluded by saying that this is the most massive explosion.
