This artist\u2019s impression is based on the aftermath of a supernova explosion as seen by two teams of astronomers with both ESO\u2019s Very Large Telescope (VLT) and ESO\u2019s New Technology Telescope (NTT). The supernova observed, SN 2022jli, occurred when a massive star died in a fiery explosion, leaving behind a compact object \u2014 a neutron star or a black hole. This dying star, however, had a companion which was able to survive this violent event. The periodic interactions between the compact object and its companion left periodic signals in the data, which revealed that the supernova explosion had indeed resulted in a compact object.<\/figcaption><\/figure>\n

Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the Universe \u2014 black holes and neutron stars. With the help of the European Southern Observatory\u2019s Very Large Telescope (ESO\u2019s VLT) and ESO\u2019s New Technology Telescope (NTT), two teams were able to observe the aftermath of a supernova explosion in a nearby galaxy, finding evidence for the mysterious compact object it left behind.<\/p>\n

When massive stars reach the end of their lives, they collapse under their own gravity so rapidly that a violent explosion known as a supernova ensues. Astronomers believe that, after all the excitement of the explosion, what is left is the ultra-dense core, or compact remnant, of the star. Depending on how massive the star is, the compact remnant will be either a neutron star \u2014 an object so dense that a teaspoon of its material would weigh around a trillion kilograms here on Earth \u2014 or a black hole \u2014 an object from which nothing, not even light, can escape.<\/p>\n
