Scientists have recorded in space a birth of a pulsar

Ученые зафиксировали в космосе рождение пульсара

It was formed in place of an extinguished supernovae and again lit itSix years ago, the researchers observed the exploding star – a supernova in the spiral galaxy NGC 4790. The supernova, named SN 2012au shone in the constellation Virgo, and then gradually diminished. But recently a group of scientists from Purdue University noticed that a gaseous residues of the explosion broke out again, and it happened without any outside interference.

Sometimes the remains of the gas collide with the gas, rich in hydrogen, and it glows with new strength. But, according to astronomers, in this case there was something more interesting: “fragments” star became a pulsar, a supernova lit like a light bulb.

This happens when large stars explode and the particles have become neutrons. If the resulting neutron star has a magnetic field and rotates fast enough, it can become a pulsar.

“We know that supernova explosions result in this type of rotating neutron stars, but we never witnessed this unique event,” say the researchers.

They emphasize that such super-bright supernovae are considered to be potential sources of gravitational waves and black holes.

Recall, astronomers decided to look for the traces of an ancient collapsed stars, from which once formed our Solar system in meteorites.
