Astronomers discover the largest explosion in deep space
Astronomers have recently discovered the largest explosion ever detected in deep space, known as AT2021lwx. This explosion was ten times more luminous than any supernova or exploding star, and lasted for three years, while supernovas only last for a few months. The initial detection of the explosion occurred in 2020 through the Zwicky Transient Facility in California, which was subsequently followed by its detection through the Asteroid Terrestrial-impact Last Alert System in Hawaii.
Telescopes located approximately 8 billion light-years away from Earth are currently detecting this event. The Monthly Notices of the Royal Astronomical Society published a study indicating that the brightness of this occurrence was three times greater than that of tidal disruption events. Tidal disruption events occur when a star plunges into a supermassive black hole.
According to astronomers, it is speculated that a gigantic gas or dust cloud, possibly thousands of times larger than our sun, was disrupted by a supermassive black hole in space. It is hypothesized that the cloud deviated from its regular orbit and was pulled toward the black hole. The black hole then consumed fragments of the hydrogen cloud, leading to shockwaves that propagated through the remaining parts of the cloud and the swirling mass of matter orbiting around the black hole.
The AT2021lwx event surpasses gamma-ray burst GRB 221009A, which was detected in 2020 and is one of the brightest cosmic explosions ever recorded in space. According to the research team and astronomers, the brightness of the event was so immense that it was equivalent to 100 times the brightness of all the stars present in the Milky Way galaxy, which is estimated to contain around 100 billion stars.
Dr. Philip Wiseman, the lead author of the study, said that the team discovered the event accidentally while searching for a type of supernova using their search algorithm. The team was initially puzzled by what could have caused such an incredibly bright phenomenon. There was no scientific literature that could explain something that bright and long-lasting. According to Wiseman, most supernovae and tidal disruption events fade away after a few months, making the object’s brightness for over two years exceptionally rare. Wiseman is also a research fellow at the University of Southampton in England.
Dr. Matt Nicholl, a co-author of the study, suggested that it is improbable to encounter such a massive star, so it is more likely that a much larger cloud of gas is responsible for the event. Researchers have observed that many massive black holes are surrounded by gas and dust, and they are still trying to determine why this particular black hole started feeding so rapidly and unexpectedly. Quasars, or supermassive black holes that constantly consume gas at high velocities, are the only space objects that could compete with AT2021lwx.
According to Professor Mark Sullivan, another co-author of the study and a professor at the University of Southampton, the sudden appearance of AT2021lwx with the brightness of the brightest things in the universe, which is unparalleled, is unprecedented, as no detection of AT2021lwx was observed over the past ten years.
This discovery is significant as it provides new insight into the formation and evolution of galaxies. The event suggests that supermassive black holes can have a significant impact on the evolution of galaxies by disrupting the gas and dust clouds around them, and thereby affecting the growth of stars.
The study also highlights the importance of ongoing research and the development of new technologies to detect such events in deep space. The discovery of AT2021lwx provides astronomers with a unique opportunity to study the properties of black holes and the effects of their interactions with surrounding matter.
