Scientists have spotted two bright radio bursts from a magnetar in our galaxy as they approach the discovery of the source of the explosions.
Earlier this month, scientists discovered that radio explosions came from the object - a breakthrough in the search for the source of these mysterious bursts of energy. It is the first time an FRB has been detected coming out of our galaxy, and also the first time such an explosion has been detected at a specific source.
Now scientists say they have found new explosions coming from the same magnetar. This would help us to see if this is the real source of FRBs - and if it is the same procedure could amplify these explosions that we discovered that come from from elsewhere in the universe.
Rapid radio bursts are very small and very powerful bursts of radioactivity sent through universe. Although as short as a fraction of a millisecond, they can send as much energy as the Sun sends out in a matter of days - and they are mostly unpredictable.
Astronomers have been searching for an explanation for the eruptions since 2007, when it was first discovered. Possible origins have included everything from dying stars and black holes to extraterrestrial technology.
This hunt was mostly vague and it is not yet clear what exactly causes it. explosions. But scientists this year discovered that one of the explosions came from inside galaxy and specifically from a magnetar (a neutron star with an incredibly strong magnetic field).
A few days after this finding, the researchers spotted far fewer explosions coming from the same source, which is officially known as SGR1935 + 2154. It seems to have similarities to other recurring rapid radio bursts detected earlier and outside the solar our system.
The researchers hope that the discovery of these explosions, as well as the deeper work to understand how active the source is, can show if they are similar to the source of others. FRB that have come to us from outside our galaxy.
The researchers conclude that the magnetar in our galaxy "creates a fascinating case of some relationship between (at least some) FRBs and magnetars". There are still some key questions, however, and scientists say further monitoring of the object known as SGR1935 + 2154 will yield more απαντήσεις in the future.
The research is described in a new paper published in Nature Astronomy entitled "Detection of two bright radio bursts from magnetar SGR 1935 + 2154".
