Black widow pulsar distance from earth
WebCredit: NASA/CXC/M.Weiss. Black Widow Pulsar (B1957+20) is a binary pulsar, discovered in 1988, in which a pulsar, with a pulse period of 1.6 milliseconds, is in an eclipsing orbit with a normal stellar companion. The signal from the pulsar is delayed, causing the period to lengthen, a few minutes before eclipse and for about 20 min after … The Black Widow Pulsar (PSR B1957+20) is an eclipsing binary millisecond pulsar in the Milky Way. Discovered in 1988, it is located roughly 6,500 light-years (2,000 parsecs) away from Earth. It orbits with a brown dwarf or Super-Jupiter companion with a period of 9.2 hours with an eclipse duration of approximately 20 minutes. When it was discovered, it was the first such pulsa…
