Essentially, FRBs are bright bursts of radio waves (radio waves can be produced by astronomical objects with changing magnetic fields) whose durations lie in the millisecond-scale, because of which it is difficult to detect them and determine their position in the sky.<\/p>\n\n\n\n
The source of the FRB detected in April in the Milky Way is a very powerful magnetic neutron star, referred to as a magnetar, called SGR 1935+2154 or SGR 1935, which is located in the constellation Vulpecula and is estimated to be between 14,000-41,000 light-years away.<\/p>\n\n\n\n
Before April this year, scientists did not have any evidence to show that FRBs could be blasted out of a magnetar. Therefore, the observation is especially significant.<\/p>\n\n\n\n
As per NASA, a magnetar is a neutron star, \u201cthe crushed, city-size remains of a star many times more massive than our Sun.\u201d<\/p>\n\n\n\n
The magnetic field of such a star is very powerful, which can be over 10 trillion times stronger than a refrigerator magnet and up to a thousand times stronger than a typical neutron star\u2019s.<\/p>\n\n\n\n
Neutron stars are formed when the core of a massive star undergoes gravitational collapse when it reaches the end of its life.<\/p>\n","protected":false},"excerpt":{"rendered":"
NASA has reported that on April 28, it observed a mix of X-ray and radio signals never observed before in the Milky Way. Significantly, the flare-up it observed included the first fast radio burst (FRB) seen within the galaxy.
