An intermittent radio signal from space intrigues astronomers

These signals often originate from rotating neutron stars known as pulsars, and typically emit regular flashes of radio waves.

Astronomers have discovered sporadic explosions Radio signals, called “transient radio signals”, coming from deep space. These signals often originate from rotating neutron stars known as pulsars, and typically emit regular flashes of radio waves.

Recently, a transient radio cycle lasting approximately one hour was discovered, the longest ever recorded. This signal proved strange and emissive Long, bright flashes– Fast and weak heartbeat, and sometimes nothing comes out of it. It is believed that it could be a very unusual neutron star, but other possibilities cannot be ruled out. The research was published in the journal Nature Astronomy.

The origin of the signal remains a mystery

The origin of the remarkably long-period radio signal remains shrouded in mystery, with a slowly rotating neutron star emerging as the prime suspect, although it may be… White dwarf It cannot be disposed of.

White dwarfs, like the remains of stars sungenerally have slow rotation periods, but experts still don't understand how one could emit the observed radio signals.

One theory put forward is that the object in question could be part of a binary system orbiting an unseen star. This mystery challenges long-standing notions about neutron stars and white dwarfs, providing a new area of ​​exploration and discovery in astronomy.
