Astronomers studying the site of a supernova seen 843 years ago have captured an image of the strange filaments left behind by the stellar explosion.
This includes the most distant spectroscopically confirmed supernova at a redshift of 3.6, indicating its explosion occurred when the universe was merely 1.8 billion years old. These findings [42] offer crucial insights into the early universe's stellar evolution and the frequency of supernovae during its formative years.
Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision; Solar flares are a minor type of stellar explosion [1] Tidal disruption event, the pulling apart of a star by tidal forces
While a supernova is the explosive death of a massive star, a nova refers to the sudden, brief explosion from a collapsed star known as a white dwarf. T Coronae Borealis, otherwise known as the ...
NASA artist's impression of the explosion of SN 2006gy, a superluminous supernova. A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. [1]
The explosion, observed on March 7, was the second brightest gamma-ray burst ever witnessed by telescopes in more than 50 years of observations, over one million times brighter than the entire ...
SN 2006gy was an extremely energetic supernova, also referred to as a hypernova, [4] that was discovered on September 18, 2006. It was first observed by Robert Quimby and P. Mondol, [2] [5] and then studied by several teams of astronomers using facilities that included the Chandra, Lick, and Keck Observatories.
Astronomers have found evidence that a neutron star exists at the centre of the only exploding star – supernova – visible to the naked eye in the last 400 years, solving a 30-year-old mystery.
