100 Percent Chance A Milky Way Supernova Will Be Visible From Earth
The Fred Lawrence Whipple Observatory’s 48-inch telescope captured this visible-light image of the Pinwheel galaxy (Messier 101) in June 2023. The location of supernova 2023ixf is circled. The observatory, located on Mount Hopkins in Arizona, is operated by the Center for Astrophysics | Harva...
There won’t be any danger to Earth from some 650 light years away, but the dying star will shine almost as brightly as the moon, visible even during the day for several months. When it finally dims it will become invisible to the naked eye. The hunter, known to humans for a...
the team’s success in identifying and analyzing SN Zwicky is only the beginning. Now still in its construction phase, the new observatory is expected to begin full operations in 2024 and build upon the team’s findings as it takes multiple images of the entire visible sky to se...
SN 2023xxj is a Type IIn on the position of an anonymous (but visible on the DSS2 plates) galaxy in Antlia. Supposedly it reached 16.9 mag on 12/22. However, its redshift is given at 0.097 which should have made it about 2.5 magnitude dimmer. Something looks off, particularly since th...
According to historical records, that supernova, 30 times more distant from Earth than Betelgeuse, remained visible during the day for over three weeks. Montargès expects Betelgeuse to soon return to within its limits. For the next few months, the star won't be visible, as it will get too...
Located some 650light-yearsfromEarth, Betelgeuse, also known as Alpha Orionis, usually ranks as the tenth brighteststarin the night sky. The star, however, is known for its periodic dimming and brightening up, which sometimes makes it climb a bit up or down the ranking. ...
Wide-field image of the Orion Constellation, a prominent constellation located on the celestial equator and visible throughout the world. Betelgeuse is the bright, red star just left of center. It’s fortunate Earth isn’t near a giant star with a heaving, unstable outer atmosphere, because th...
Type Ia supernovae are thought to be potentially the most dangerous if they occur close enough to the Earth. Because these supernovae arise from dim, common white dwarf stars, it is likely that a supernova that can affect the Earth will occur unpredictably and in a star system that is ...
The supernova SN 1987A occurred 160,000 light-years from Earth in the Large Magellanic Cloud. It was first observed on Earth in February 1987, and its brightness peaked in May of that year. It was the first supernova that could be seen with the naked eye since Kepler’s Supernova was...
