Vela Pulsar (PSR 0833-45)
 |
X-ray emission nebula surrounding the Vela Pulsar

A pulsar associated with the Vela
Supernova Remnant and lying at a distance of about 815 light-years in
the constellation Vela. It is one of the youngest
pulsars known and one of the few that has been detected at visible wavelengths.
The lengthening of its short period of 89 milliseconds by 10.7 nanoseconds
per day gives a maximum age of some 11,000 years. In 1977, nine years of
its discovery, it was seen to be flashing at visible wavelengths and thus
became the second optical pulsar on record, after the Crab
Pulsar. It is also one of the strongest radio pulsars, the strongest gamma-ray
source in the sky, and a powerful X-ray source
associated with Vela X-2.
