Antimatter spewing from 'afterlife' object detected

Legendary antimatter has filled space from a dead star's escape.

The spectacular sight has just been recorded by NASA's Chandra X-ray Observatory. A pulsar known as PSR J2030 + 4415, about 20km in diameter but carrying "super energy", is fleeing through space at a dizzying speed of about 450km/s.

The pulsing star and its brilliant blue light tail

A pulsar is a rapidly rotating neutron star that emits a huge source of beams of energy, mainly in the form of radio waves. Neutron stars are usually giant stars that have. experienced death twice: once collapsing into a white dwarf after running out of energy, and then again collapsing into a neutron star.

Neutron stars are small but extremely dense and powerful, pulsars are very powerful forms of neutron stars. A neutron star weighs between 8-30 times the mass of the sun despite being only a few tens of kilometers in diameter.

This time, the strange pulsar ejected a giant comet-like tail, filled with particles of electron-matter and antimatter positrons.)

"The magnetic field of the pulsar wind is associated with the interstellar magnetic field, the clump spewing matter and antimatter particles. Particles leaking from the stellar wind appear to have been accelerated along the midfield magnetic field lines. stars, reaching one-third the speed of light, produce brilliant X-ray beams," explains astronomer Roger Romani from Stanford University.

The study has just been published in arXiv and has been accepted for publication in The Astrophysical Journal.
