We just captured a unique space event decades ago

Over the past few days, telescopes around the world have been pointing in the direction of the bowArrow constellation. The reason was gamma ray burst (Gamma Ray Burst, or GRB). It is one of the most powerful and brightest cosmic explosions ever. Thanks to the OHMAN Early Warning System, astronomers from around the world were able to analyze the event.

1.9 billion years ago.
The GRB eruption was detected on October 9 and attracted the attention of a large number of researchers. The explosion was detected by NASA’s Gamma Ray Space Telescope, Fermias well as Neil Geirels Swift Observatory The veteran warrior wind space probe.

eruption was Indexed under the name GRB 221009A. Despite the gray name, the event was marked by its relative proximity to us, even though the signal required 1,900 million years to reach our solar system.

A unique event decades ago.
Roberta Pellera explained: “This eruption is much closer to typical GRBs, which is exciting because it allows us to detect many details that would otherwise be too faint to be seen.” In the press release Published by NASA, which led the first communications about this phenomenon.

On the other hand, Bellera also noted that the recent explosion “is among the most energetic and brightest ever, regardless of distance, which makes it doubly exciting.”

cosmic collapse.
The origin of the signal may be due to the collapse of a star and the formation of a Black hole. The end of a star’s life could be a super cosmic event. In the case of more massive stars, the end of their existence as such is in the form of a massive explosion: Supernova explosion or gamma ray burstdepending on factors such as the mass and metallicity of the star.

Also depending on the mass of the remaining stellar core, the death of the star can result in either a neutron star or a black hole. This transit between massive stars and black holes is still full of unknowns.

All eyes are on Sagittarius.
Some unknowns can be solved thanks to GRB 221009A. It is thanks to its ruggedness, proximity and proper operation of communication protocols that it has allowed many monitoring tools to set their sights on it.

Thanks to this, the event also has significance on a technological level, as it serves Implementation of new communication systems between the different tools. The High Power Orbital Monitor Alert Network (OHMAN) is a mechanism that connects two instruments operating on the International Space Station, the NICER X-ray Telescope and the Monitor All-Sky X-ray Imaging (MAXI).

This new connection allows the devices to coordinate without the need for human intervention, so that NICER can act quickly on bursts like those detected by a MAXI device.

10 hours with GRB 221009A.
In addition to the proper functioning of these communication protocols, another factor associated with the strength and proximity of the eruption that plays in favor of astronomers is its duration. The Fermi Large Telescope (LAT) was able to observe the event for 10 hours, while the NICER instrument was able to capture it for three hours.

As usual, we’ll still have to wait for astronomers to evaluate the data from this burst. In the meantime, NASA published Some pictures From the event he captured some of his gadgets.
