When this happens, often there is a <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/spaceplace.nasa.gov\/supernova\/en\/\">tremendous explosion known as a supernova<\/a>.<\/p>\n<p>The fact that the black hole in VFTS 243 system is in a circular orbit with the star is strong evidence that there was no supernova explosion, which otherwise might have <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/doi.org\/10.1093\/mnras\/stz2335\">kicked the black hole<\/a> out of the system \u2013 or at the very least disrupted the orbit. Instead, it appears that the progenitor star <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/doi.org\/10.3847\/0004-637X\/821\/1\/38\">collapsed directly<\/a> to form the black hole sans explosion.<\/p>\n<p>The massive star in the VFTS 243 system will live for only another 5 million years \u2013 a blink of an eye in astronomical timescales. The death of the star should result in the formation of another black hole, transforming the VFTS 243 system into a black hole binary.<\/p>\n<p>To date, astronomers have detected nearly 100 events where binary black holes merge and <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/theconversation.com\/gravitational-waves-discovered-top-scientists-respond-53956\">produced ripples in space-time<\/a>. But how these binary black hole systems form is still unknown, which is why VFTS 243 and similar yet-to-be-discovered systems are so vital to future research. Perhaps nature has a sense of humor \u2013 for black holes are the darkest objects in existence and emit no light, yet they illuminate our fundamental understanding of the universe.<!-- Below is The Conversation's page counter tag.
