PSR B1919+21 is a pulsar with a period of 1.3373 seconds [4] and a pulse width of 0.04 seconds. Discovered by Jocelyn Bell Burnell on 28 November 1967, it is the first discovered radio pulsar. [ 5 ] The power and regularity of the signals were briefly thought to resemble an extraterrestrial beacon , leading the source to be nicknamed LGM ...
PSR B1257+12, previously designated PSR 1257+12, alternatively designated PSR J1300+1240, [6] is a millisecond pulsar, 2,300 light-years (710 parsecs) from the Sun, in the constellation Virgo, rotating at about 161 times per second (faster than the blade of a blender). [1]
The convention that arose for designating pulsars was that of using the letters PSR (Pulsating Source of Radio) followed by the pulsar's right ascension and degrees of declination. The modern convention prefixes the older numbers with a B meaning the coordinates are for the 1950.0 epoch. All new pulsars have a J indicating 2000.0 coordinates ...
Collectively, the RTGs supply each Voyager spacecraft with 470 watts at launch. [7] [8] MHW-RTGs were used on the Lincoln Experimental Satellites 8 and 9. Subsequent US spacecraft used the GPHS-RTG, which used similar SiGe thermoelectric devices but a different packaging of the fuel. The MMRTG is a newer RTG type, used on the Curiosity rover.
X-ray pulsar-based navigation and timing (XNAV) or simply pulsar navigation is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a vehicle, such as a spacecraft in deep space. A vehicle using XNAV would compare received X-ray signals with a database of known pulsar frequencies ...
PSR B1257+12 C, alternatively designated PSR B1257+12 d and also named Phobetor, is a super-Earth exoplanet orbiting the pulsar Lich approximately 2,315 light-years (710 parsecs; 22 quadrillion kilometres) away from Earth in the constellation of Virgo.
