Using NASA’s Hubble Space Telescope, astronomers have solved a longstanding mystery on the type of star, or so-called progenitor, which caused a supernova seen in a nearby galaxy.
The recently discovered strange spinning star appears to be older than the explosion in which it has been born.
The Explosion of Tycho’s Supernova may allow for researching the origin of cosmic gamma rays. super-speedy subatomic particles that crash constantly into Earth’s atmosphere. The Tycho’s supernova is located 10,000 light-years away from the Earth in the constellation Cassiopeia has exploded in November 1572 and remained visible in the sky for about 15 months.
Scientists make assured that there is no possibility that the Betelgeuse star will become a supernova and will explode someday soon.Betelgeuse is one of the brightest stars in the sky that lies some 430 light-years from Earth.
Astronomers have found the first direct evidence that some star explosions are triggered by compact stars called white dwarfs. Scientists studying the youngest type of Ia supernova ever found worked backward to pinpoint its explosion time with unparalleled accuracy.
Using the Fermi Gamma-Ray Space Telescope, astronomers have found that the shattered remains of the 1572 supernova event known as Tycho supernova live on in high-energy gamma rays, providing vital insight into the generation of cosmic rays.
In this new image from NASA’s Wide-field Infrared Survey Explorer (WISE), Puppis A looks less like the remains of a supernova explosion and more like a red rose.
Astronomers have spotted the fastest rotating star yet found, a massive and bright young star located in our neighboring dwarf galax, the Large Magellanic Cloud.
The Christmas sky last year was lit up by an extraordinarily powerful and mysteriously long-lasting explosion in space that scientists now suggest was a comet smacking into a dense star or a peculiar supernova death.
