Radio signal coming from our galaxy, scientist surprised

The hidden secrets of our galaxy i.e. ‘Milky Way’ astonish the whole world including scientists. Now scientists have detected a mysterious radio signal emanating from the Milky Way. This signal has surprised the scientists. They say that this signal is probably coming out of a white dwarf pulsar. Pulsar is a rotating neutron star, which emits radiation at regular intervals. It ranges from a few milliseconds to seconds. Researchers have named this mysterious signal as ‘GLEAM-X J162759.5-523504.3’. Jonathan Katz of the University of Washington writes in his research paper about the characteristics of this mysterious signal that since the early days of pulsar astronomy, there has been speculation about a rotating magnetic white star showing pulsar-like activity.

Pulsars spin very fast and angle in such a way that beams of radio waves from the magnetic poles pass over Earth with each rotation. Scientists wonder whether similar behavior can be observed in white dwarf stars. Jonathan Katz has posted his research paper on the preprint server arXiv upload Is done. It is yet to be reviewed.

Where this signal comes from is located about 4,000 light-years away from Earth. Many scientists have studied about this object. These include Australian researchers, who discovered it using a telescope named Murchison Widefield Array located in Western Australia. Data gathered by the telescope between January and March 2018 showed this object pulsating rapidly for about 30 to 60 seconds every 18.18 minutes.

We had told you another news related to stars in the past. When a star explodes, it becomes very bright. This is called supernova. The European Southern Observatory (ESO) captured images of an explosion in the Cartwheel galaxy. This explosion happened in a star. The name of this supernova is SN2021afdx, which has been identified as a Type II supernova. This type of supernova is formed when the fuel of a massive star runs out. This fuel is necessary for the star’s gravity and prevents it from collapsing.
