Insets at lower right show one epoch of Webb observations, while the inset at left shows a Webb image of the central supernova remnant released in 2023. "Even as a star dies, its light endures ...
The supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole, based on current stellar evolution models. The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy. [3] By 22 May 2023, SN 2023ixf had brightened to about ...
Boom.In the colossal Pinwheel galaxy, 25 million light-years away, a star has just exploded and is even visible through small telescopes. The supernova-hunting astronomer Koichi Itagaki discovered ...
SN 2021aefx was observed in multiband by the Precision Observations for Infant Supernovae Explosions (POISE) a day after discovery. The photometry was obtained on the 1 m Swope Telescope at the Las Campanas Observatory. Observations were acquired twice per night in order to look for small scale fluctuations in the light curve.
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
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.
It is a type of stellar explosion that ejects material with an unusually high kinetic energy, an order of magnitude higher than most supernovae, with a luminosity at least 10 times greater. Hypernovae release such intense gamma rays that they often appear similar to a type Ic supernova , but with unusually broad spectral lines indicating an ...
The supernova was a Type Ic supernova, similar to SN 1998bw, the first supernova linked to a GRB. Lightning detectors in India and Germany picked up signs that the Earth's ionosphere was perturbed for several hours by the burst, though only mildly, [ 37 ] [ 17 ] [ 4 ] as well as an enormous influx of electrically charged particles, [ 38 ...
