Usa, the interferometer LIGO has detected an unusual gravitational wave from a source not known
the WASHINGTON - A mysterious "ripple" in the fabric of space-time has been detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States. It happened last Tuesday when an unusual and unexpected gravitational wave has hit the Ground and seemed to be coming from somewhere near the red supergiant in the constellation Orion, the star Betelgeuse. At the moment scientists can not say with certainty what has caused this gravitational wave, or if it is 100 per 100 of a gravitational wave is authentic, and this is because of its unusual nature. There is also the possibility that it is a "false positive". So far the waves detected by LIGO have all been linked to significant events such as the collision of two black holes or the merger of neutron stars, but this is a "new wave".

This type of "explosion", according to the scientists, it may be connected to phenomena such as a supernova or gamma-ray bursts. The hypothesis that this could be linked to a possible explosion of a supernova has led some astronomers to think if they were about to witness the death of the supergiant red Betelguese. The star has about eight million years and it is expected that in the next 100 thousand years to become a supernova. Recently the star has behaved in a strange way, becoming much more weak compared to when I started the observations modern.
The astronomer Andy Howell said that it is unlikely that Betelgeuse might explode. According to the expert, there was a significant increase in the detection of neutrinos, something that you would expect to see if a star becomes a supernova.

astronomers have already rotated their telescopes in the area of the sky where they were detected gravitational waves in the hope of discovering the true cause. According to Jessie Christiansen, a scientist at Nasa, even some of the larger telescopes they will change their study objective. The exact location has not yet been identified because of the unusual nature and the unexpected explosion, but LIGO expects to find more details in the coming days or in the next few weeks. At the time LIGO describes this most recent recognition as "gravitational waves crashing in the night". Scientists say that there is not a model that would help to confirm if it is a supernova, so it could even be something different.
