Description

A supernova is an extremely violent explosion of a star many times more massive than our Sun. During this explosion, the star may become as bright as all the other stars in a galaxy combined, and in which a great deal of matter is thrown off into space at high velocity and high energy. The remnant of these massive stars collapse into either a neutron star or a black hole.

Supernova of 386 AD
Description: This composite radio and X-ray image shows G11.2-0.3, the remnant of a supernova observed by Chinese astrologers in 386 A.D. as a "guest star" in the Nan-tou Asterism. The radio data were obtained by scientists studying this supernova remnant with…

Supernova 1993J

Supernova 1986J
Description: SN 1986J in the galaxy NGC 891 is one of the most radio luminous supernovae ever discovered. Indeed, at a distance of about 31 million light-years, it had a peak luminosity at 5 GHz about 8 and 13 times greater than SN 1979c and SN 1993J,…

Supernova 1993J and its Fourier Transform
Description: Supernova 1993J as seen with Very Long Baseline Interferometry. This image is made from observations using a world-wide array of 18 radio telescopes, including the NRAO Very Long Baseline Array, Very Large Array, Green Bank Telescope and antennas of…

Supernova 1993J
Description: SN 1993J was discovered March 28, 1993, by Francisco Garcia Diaz, an amateur astronomer in Lugo, Spain, using a 10-inch Newtonian telescope. Located in M81, a spiral galaxy in the constellation Ursa Major, the distance of this supernova from Earth is…
