In May 2023, researchers called on amateur astronomers around the world for early data they had collected on the explosion of a nearby red supergiant star. Images a to d show the supernova explosion of SN 2023ixf turn from red to ...
Nearby star-forming regions are clearly seen. c, Hα image of the direct vicinity of SN 2023ixf, as marked in the Liverpool Telescope g-band image, constructed from observations with the integral field unit KCWI. The SN explosion site is embedded in a region of continuing star formation...
During the lifetime of our Milky Way galaxy, there have been something like 100 million supernova explosions, which have enriched the Galaxy with the oxygen we breathe, the iron in our cars, the calcium in our bones and the silicon in the rocks beneath our feet. These exploding stars also...
A supernova is the explosion of a massive star. There are many different types of supernovae, but they can be broadly separated into two main types: thermonuclear runaway or core-collapse. This first type happens in binary star systems where at least one star is a white dwarf, and they'...
We find that the star is completely disrupted by explosive oxygen burning, and this type of explosion as a possible scenario for the Cassiopeia A remnant. This scenario seems to be also applicable to the supernova 1985f according to the recent observations of this object....
Here we present a new event, SN2016aps, offset from the centre of a low-mass galaxy, that radiated ≳5 × 1051 erg, necessitating a hyper-energetic supernova explosion. We find a total (supernova ejecta + CSM) mass likely exceeding 50−100 M⊙, with energy ≳1052...
A Type II supernova occurs when a star, which is at least nine times heavier than the sun, burns almost all of its fuel. The fusion engine in the center of the star begins to stutter, which triggers an internal collapse, followed by a violent explosion of the entire star. ...
[00:26.20]The explosion takes place at the end of a star's life. [00:31.92]The current process for discovering supernovas [00:36.80]usually involves both machines and people. [00:41.44]Telescopes repeatedly collect images of...
The researchers propose a few scenarios that may have affected Fermi’s ability to see gamma rays from the event, like the way the explosion distributed debris and the density of material surrounding the star. Fermi’s observations provide the first opportunity to study conditions right after the...
A supernova explosion is a cataclysmic explosion that marks the violent end of a massive star’s life. During the event, the star releases immense amounts of energy, often outshining the combined light from all the stars in the host galaxy for a very brief period of time. The...
