Possibly, the reason we're seeing this energetic activity at varying wavelengths - X-ray, infrared and radio - is that their properties are changing over time. In fact, such flares have been detected in the past through both X-ray and infrared observations of Sagittarius A*, but this is the first time anyone has discovered them through radio telescope data - and with a "very strong indication" at that. The study scientists think their newly located hot spot, according to the European Southern Observatory, is associated with bursts, or flares, of X-ray energy emitted from the Milky Way's center.

"We think we're looking at a hot bubble of gas zipping around Sagittarius A* on an orbit similar in size to that of the planet Mercury, but making a full loop in just around 70 minutes," Maciek Wielgus, of the Max Planck Institute for Radio Astronomy in Germany and lead author of the study published in Astronomy & Astrophysics, said in a statement. This spot, they say, seems to be dimming and brightening while traveling clockwise around Sgr A*. And last month, a crew working with a powerful radio telescope called the Atacama Large Millimeter/submillimeter Array Observatory gleaned some novel clues.Īfter checking out ALMA data recorded in tandem with EHT observations of Sgr A*, during the black hole's monumental imaging procedure, the team spotted what it calls a "hot spot" flitting around the abyss. There was far more to learn from Sgr A*.įrom Earth's vantage point, about 27,000 light-years away from this black hole, astronomers have been vigilantly watching and studying the void in an attempt to decode how, exactly, the Milky Way's ferocious engine works. This marked the first time we ever laid eyes on her majesty - a tremendous moment in its own right - but scientists weren't done yet. It was a mind-bending portrait of Sagittarius A*, the mighty black hole anchoring our galaxy, its gravitational pull silently brushing every star, planet and asteroid within.

The next step for the researchers is to explore such events further to understand whether this actually happens more regularly and whether astronomers simply have not been looking at TDEs late enough in their life cycle. “It’s as if this black hole has started abruptly burping out a bunch of material from the star it ate years ago,” explained Cendes.Īlso, the outflow of material from TDEs usually travels at around 10 per cent the speed of light while in this example, it was going as fast as 50 per cent the speed of light, adding more questions to the mystery. But this usually happens almost immediately after the TDE, not years later. Some of this spaghettified materially gets flung back into space sometimes. Then, the elongated material spirals around the black hole, gets heated up, and creates a flash that can be detected by us millions of light years away.īut black holes are messy eaters. When a star comes close to a black hole, the gravitational forces will stretch or “spaghettify” the star, according to the Centre for Astrophysics. It is known that TDEs emit light when they occur.
