In 1572, Danish astronomer Tycho Brahe noticed something puzzling in the night sky: a bright, new (in Latin, nova) star that faded as quickly as it appeared. Until Brahe discovered the disappearing star (which we know today was a supernova, and not a new star but rather a dying star)...
It is a close double to an 11.9 mag star Newer ones to look for are: SN 2024aecx is a Type Ic ENE of the center of the relatively bright & large galaxy NGC 3521 in Leo. While Bright Supernova page lists it as 14.1 based on an image report from 12/21, this appears erroneously ...
The new discoveries, based on data from the James Webb Space Telescope, provide a glimpse of the early universe.
Four hundred years ago this week, a previously unseen star suddenly appeared in the night sky. It was brighter than all other stars, and many people noticed it beginning Oct. 9, 1604.
The most dramatic supernova was observed in the year 1006. It appeared in May as a brilliant point of light visible during the daytime, perhaps 100 times brighter than the planet Venus. It was bright enough to cast shadows on the ground during the night and was recorded with awe and fear...
Super-luminous supernovae are the brightest explosions in the Universe. In just a few months, a super-luminous supernova can release as much energy as our Sun will in its entire lifespan. And at its peak, it can be as bright as an entire galaxy. ...
It isn't getting as bright as I anticipated so it is either a somewhat under-luminous Type Ia, partially obscured by dust (less likely based on its galactic position), or the distance is about 1.8x what I had seen stated for the galaxy. The redshift would have made it a lotbrighterth...
History Five times in the last millennium, a new star suddenly appeared in the sky. Initially very bright, it progressively declined to finally disappear after a few months or a few years. The first star, in 1006, was the brightest one, even visible during daytime. It was followed in 1054...
With his colleagues from Stony Brook University, the University of Ohio, and the Max Planck Institute for Astrophysics, Page conducted a theoretical study about SN 1987A's brightness. Their conclusion, the neutron star is particularly bright because it's so young. As heexplained: ...
(e.g.Kashiyama et al., 2013; Abbott et al., 2016a), it will become possible to capture the SN shock exploding through the progenitor star, which is known as a“SN shock break-out”. As such an event occurs within minutes to hours, they have only ever been detected ...
