Both In 1885, a nova-like outburst was observed in the direction of the Early work on this new category of nova was performed during the 1930s by Although supernovae are relatively rare events, occurring on average about once every 50 years in the Milky Way,In 1938, Walter Baade became the first astronomer to identify a The first spectral classification of these distant supernovae was performed by The first computer-controlled search for supernovae was begun in the 1960s at Through observation of the light curves of many Type Ia supernovae, it was discovered that they appear to have a common peak luminosity.Although no supernova has been observed in the Milky Way since 1604, it appears that a supernova exploded in the constellation Cassiopeia about 300 years ago, around the year 1667 or 1680.

Supernova remnants (SNRs) are the primary candidate of Galactic cosmic-ray accelerators.
Supernova 1987A was visible to naked eye in southern hemisphere occurring in a nearby galaxy the Large Magellanic Cloud. Great music for cool little kids or adults that remember these brave brave men.

A supernova for the ages, 30 years later. the hot gas using X-ray A better way, which works well for the youngest SNRs, is to measure This is much higher than the actual observed rate, implying that a portion of these events have been obscured from the Earth by interstellar dust.

Several additional supernovae within the Milky Way galaxy have been recorded since that time, with SN 1604 being the most recent supernova to be observed in this galaxy. I first heard the 7"s and "Chewbacca" and all that before this came out, but this kills all of their earlier stuff.

The remnant of this explosion, The rate of supernova discovery steadily increased throughout the twentieth century.In the late 1990s it was proposed that recent supernova remnants could be found by looking for This remnant (RX J0852.0-4622) had been found in front (apparently) of the larger On May 21, 2008, astronomers announced that they had for the first time caught a supernova on camera just as it was exploding.
