In 2006 and 2007, astronomers associated with the supernova heritage survey discovered two of the brightest supernovas ever. Such a large supernova, in fact, astronomers initially did not know what they were or how far we were in them.

"At first, we didn't know what these things were, and it wasn't even clear whether they were supernovae or whether they were in our Milky Way or in a distant Milky Way," wrote scientist Dr. Andrew Howell in a press release. Road.
Howell was the main author of a study published in the Astrophysical Journal by him and a group of researchers who discovered more about the results of these two mysterious supernovae.
They discovered that the two supernovae exploded before the birth of our solar system. They estimated that the time of the explosion was about 10 billion light-years ago. In fact, they are a type of supernova that may no longer be formed, and are an early form of supernova that are almost extinct. They are the relics of those supernovae. "The author wrote in the paper.
They are extinct because the early cosmic environment they formed was completely different from what we now know about the cosmic environment.
"These environments were common in the early universe, when the rate of star formation was higher than the current rate of star formation in the universe, and the metal accumulation did not reach current levels," the researchers wrote in the report.
According to astronomers, these supernovae may mark the formation of neutron stars that spin very fast. The quality of these magnetic planets is the same as the quality of our Sun, but they are very dense and only have the size of a city.
"How could it be that the planet was spinning at a very fast pace," said researcher Donald Carson in the press release, "It will eventually die, and the collapse of the magnet's core may spin up a huge top. That's huge." The rotating energy will be released in an angry magnetic field. "
Astronomers have discovered through ordinary observation that two supernovae like this are very rare, and there is only one such superstar in 10,000 planets. Now scientists have a better understanding of how to measure their light and figure out where they are. Scientists can use this knowledge to learn more about them and understand the early universe.
"We hope to find more such supernovas from ongoing and future surveys." Howell wrote in a press release.
