Betelgeuse Supernova , Will Be Clearly Visible From Earth.<br />'Newsweek' reports that a spectacular night sky <br />show might be in store for Earth as our stellar <br />neighbor Betelgeuse nears its end.<br />Approximately 650 light years from Earth, <br />Betelgeuse has been growing increasingly bright, <br />reaching 142% of its normal luminosity in May.<br />Scientists believe this brightening <br />is a sign the star may be <br />preparing to go supernova.<br />When it occurs, the stellar explosion is expected <br />to appear clearly in both the day and nighttime <br />sky, appearing about as bright as a full moon.<br />The red supergiant, which is approximately <br />15 to 20 times larger than our Sun, <br />is located in the Orion constellation.<br />[After the supernova] Betelgeuse <br />would then fade over the next several <br />months but remain visible in <br />the daytime for six to 12 months, Albert Zijlstra, Professor of astrophysics at the <br />University of Manchester, via 'The Conversation'.<br /> At night, you should be <br />able to see it with the naked eye <br />for another one or two years, Albert Zijlstra, Professor of astrophysics at the <br />University of Manchester, via 'The Conversation'.<br />But after that, we would never <br />see it again—Orion would <br />forever lose its red sparkle, Albert Zijlstra, Professor of astrophysics at the <br />University of Manchester, via 'The Conversation'.<br />But after that, we would never <br />see it again—Orion would <br />forever lose its red sparkle, Albert Zijlstra, Professor of astrophysics at the <br />University of Manchester, via 'The Conversation'.<br />'Newsweek' reports that the last supernova that was visible <br />from Earth occurred in 1987, when SN 1987A reached its <br />fiery end in the neighboring Large Magellanic Cloud galaxy.<br />Before that, SN 1604, otherwise known as <br />Kepler's Supernova, occurred in 1604 and was <br />bright enough to be visible during the day
