The cosmic monster in the Sculptor’s Galaxy, also known as NGC 253, emits a tremendous amount of energy. This is similar to the energy of a billion of our suns, and this unusual phenomenon has its own strange explanation, SciTechDaily says.
High-frequency oscillations of a neutron star
The object, marked GRB2001415, was described by a team of scientists in his studies, published in the journal Nature, as a solitary neutron star with a very strong magnetic field. It is a magnetar whose magnetic fields reach a strength of up to 10 .15 gauss, i.e. one digit followed by up to 15 zeros. For comparison, the magnetic fields of our Sun reach about 1 gauss.
In this case, scientists were able for the first time to observe the brightness fluctuations of a neutron star during its most terrifying process. if Describe Live Science, an object 13 million light-years away, can release as much energy as the Sun over 100,000 years in just one tenth of a second (0.1 second).

According to scientists, this phenomenon is caused by instability in the magnetosphere of objects of this type or caused by something similar to earthquakes that we know. It can form in its bark, which is about a kilometer thick and flexible. However, we know how the eruptions themselves arise.
Artificial intelligence and the International Space Station
The object, which provided us with a view of an unusual phenomenon, was monitored automatically and without human intervention thanks to artificial intelligence. The instrument on the International Space Station, the Modular X-ray and Gamma Ray Sensor (MXGS), is responsible for the monitoring.
“Be that as it may, alvin waves, which are well known in the state of the sun and emit energy when they interact, form in the magnetospheres of stars.” Alberto J. explains. Castro Tirado, head of the scientific team responsible for the new study. In addition, neutron stars are relatively mysterious objects in their own right and We are still at the beginning of their observation.

The sensor in charge is part of the larger instrument ASIM (Aerospace Interaction Detector), which is supported by the European Space Agency and the countries Denmark, Norway and Spain, from which a large part of the scientific team also comes. Since such events could not be predicted, the system itself decided when to start monitoring.
They will reveal much more
According to the study, this discovery is key to a better understanding of magnetic stresses around and within neutron stars. At the same time, scientists say that we will understand this phenomenon much better if we constantly study magnetic stars in the surrounding galaxies. how write space, so far we have only been able to identify about 30 magnetospheres from about 3,000 detected neutron stars.
In the end, such an observation can make us understand one of the greatest mysteries that have plagued modern science. they are The fast radio signals constantly flooding the earth, they last only a few milliseconds and are produced by powerful astronomical processes that we don’t yet understand.

Until now It also surprised scientists, the smallest magnetic star that we were able to discover their characteristics. It is estimated to be only about 500 years old and will perform one revolution in just 1.4 seconds. In addition, it produces radio waves and has pulsar-like properties.
