100 Percent Chance A Milky Way Supernova Will Be Visible From Earth
Supernova HB9 is believed to have been visible on Earth around 3,600 B.C. with a brightness that can be compared to that of the moon. The original stone carvings and the artistic representation which is believed to depict an ancient Supernova that was visible on Earth. Image Credit: Ta...
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...
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...
Keck images, the four nearly identical “copies” of supernova Zwicky can be seen. The multiple images arise due to the warping of space caused by a foreground galaxy, also seen in the center and approximately halfway between the site of the supernova explosion and Earth. Credit...
only originate from supernova ejecta, so both the shell and the optical star definitively reside within the SNR (irrespective of their evolutionary relation or lack thereof) and at the same distance to Earth. The distance to the optical companion is well constrained by Gaia parallax measurements ...
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...
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...
