That eventual explosion explains why astronomers got excited when Betelgeuse started dimming dramatically in 2019. In 1917, George W. Ritchey measured the distance to the Andromeda Galaxy and discovered it lay much farther than had previously been thought. Dr Meredith Joyce from the Australian National University said that the star was still burning helium in its core at the moment "which means it's nowhere near exploding". The bubble is expanding at 4 million mph (2,000 kilometers per second), astronomers said. Save up to 70% off the cover price when you subscribe to Discover magazine. Betelgeuse is far outside that range, with recent studies suggesting it sits roughly 724 light-years away, well outside the danger zone. Spotting such supernovas in advance would be a boon to astronomers, who do not fully understand the death throes of a dying star. While it is normally one of the brightest stars in the sky, Betelgeuse appeared to be dimming in late 2019 - something which scientists thought could mean it was about to imminently explode. Betelgeuse is far outside that range, with recent studies suggesting it sits roughly 724 light-years away, well outside the danger zone. They decided to call this new class of cataclysmic variables super-novae, and postulated that the energy was generated by the gravitational collapse of ordinary stars into neutron stars. This means its brightness changes as it pulses up and down in size. It’s not only wildlife that would be disturbed, either; ironically, astronomers themselves would have a hard time. Two sources were found, the previously discovered Cassiopeia A remnant, and the RX J0852.0-4622 remnant, which had just been discovered overlapping the Vela Supernova Remnant, This remnant (RX J0852.0-4622) had been found in front (apparently) of the larger Vela Supernova Remnant. , The supernova SN 1006 appeared in the southern constellation of Lupus during the year 1006 AD. Even studying Betelgeuse would be a unique challenge. Betelgeuse is one of the largest stars visible to the naked eye, usually the tenth-brightest star in the night sky, occupying the top left position in the constellation Orion. All that is known about this event, mentioned in a footnote to “The Hitchhiker’s Guide to the Galaxy”, by Douglas Adams, is that the only survivor was the father of one of the story’s main characters, Ford Prefect—and that it took place on one of the planets orbiting Betelgeuse. Several additional supernovae within the Milky Way galaxy have been recorded since that time, with SN 1604 being the most recent supernova to be observed in this galaxy.
