Explore the mysteries of the universe with PSR B1951+32, a unique pulsar nestled within the CTB 80 supernova remnant. Situated approximately 8,150 light-years away in the Cygnus constellation, this star showcases the fascinating interplay of cosmic elements.
The story of CTB 80 began in 1958 when scientists first detected it as a radio source. The structure and strong polarization of CTB 80 led astronomers to propose in 1974 that it is, in fact, a supernova remnant.
The pulsar PSR B1951+32 emerged into the spotlight in 1987 when it was pinpointed as a point-like radio source. Making it even more intriguing, a year later, radio pulses were detected with a regular period of 39.5 seconds.
Delving into the data from CTB 80, researchers estimate its dynamic age to be about 10,000 years. The pulsar's movement is also noteworthy, as it travels at an impressive speed of 240 km/sec. Surrounding the pulsar, astronomers have observed emission lines from ionised hydrogen - a testament to the complex physical processes happening in the cosmos.
A closer look at PSR B1951+32 reveals a bow shock formed by the pulsar's relativistic winds as they collide with material behind the remnant's radiative shock. This cosmic spectacle is a testament to the drama and dynamism of our universe.
Take a journey into the heart of the cosmos with our composite optical image of PSR B1951+32 and its pulsar wind nebula. Captured using small amateur telescopes, the image combines broadband filters (RGB) with narrow band filters focused on the emissions of ionised oxygen ([O III]), ionised hydrogen (Hα), and ionised sulphur ([S II]). The result is a vivid depiction of the bow shock as the pulsar moves away from the explosion centre of the remnant.
