SN 1604, also known as Kepler's Supernova, Kepler's Nova or Kepler's Star, was a Type Ia supernova [1] [2] that occurred in the Milky Way, in the constellation Ophiuchus. Appearing in 1604, it is the most recent supernova in the Milky Way galaxy to have been unquestionably observed by the naked eye , [ 3 ] occurring no farther than 6 ...
It occurred approximately 51.4 kiloparsecs (168,000 light-years) from Earth and was the closest observed supernova since Kepler's Supernova in 1604. Light and neutrinos from the explosion reached Earth on February 23, 1987 and was designated "SN 1987A" as the first supernova discovered that year.
You don't know when a supernova is going to go off, and Kepler's vigilance allowed us to be a witness as the explosion began." The star observed was a particularly massive one, estimated to be 500 ...
First observed in September 2006, the supernova SN 2006gy, which occurred in a galaxy called NGC 1260 (240 million light-years away), is the largest and, until confirmation of luminosity of SN 2005ap in October 2007, the most luminous supernova ever observed. The explosion was at least 100 times more luminous than any previously observed ...
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.
A supernova is the final, fiery explosion that can destroy a dying star. It can briefly outshine entire galaxies, writes Space.com , and radiate more energy than our sun will produce in its entire ...
The last supernova directly observed in the Milky Way was Kepler's Supernova in 1604, appearing not long after Tycho's Supernova in 1572, both of which were visible to the naked eye. The remnants of more recent supernovae have been found, and observations of supernovae in other galaxies suggest they occur in the Milky Way on average about three ...
1572 – Tycho Brahe discovers a supernova in the constellation Cassiopeia. 1604 – Johannes Kepler's supernova, SN 1604, in Serpens is observed. 1862 – Alvan Graham Clark observes Sirius B. 1866 – William Huggins studies the spectrum of a nova and discovers that it is surrounded by a cloud of hydrogen.
