Radio 'photograph' of the supernova remnant Cassiopeia A (3C 461),at 6 cm wavelength,taken with the Very Large Array (VLA) radio telescope,New Mexico. Cassiopeia A is the remnant of a catastrophic stellar explosion which occured around 1658 AD. It is probably the youngest supernova remnant in our Galaxy. The ring of radio emission represents a spherically expanding cloud of gas expelled by the explosion. This image shows an area about 6 arcmin square,at a resolution better than 0.35 arcsec.
