Supermassive Black Holes Could Be Killing Way More Stars Than We Realise

One of the most violent endings in the cosmos is when a star or planet gets destroyed by a black hole. When a star gets too much close to a black hole then it is pulled apart by that black hole and simultaneously it can face a tidal disruption event (TDE). Recently, scientists have discovered that this kind of violent events is more common in the universe than estimated earlier.

Till now, the tidal disruption events were observed in very rare occasions. To be precise, up until now, a major TDE was found on only one occasion when multiple sky surveys were gazing at huge star system. But the star system was destroyed by a huge tidal disruption event. Primarily, scientists thought that it is a very rare event which may occur in a galaxy in every 10,000 to 100,000 years.

But the recent studies have shown that TDE can occur in more frequent manner. A group of scientists from the University of Sheffield has discovered that a TDE is occurring fifteen smaller galaxies in every 10 years of time. Therefore, if this theory is established then the primary theory can be surely withdrawn and at the same time, it can be proved that a TDE can occur 100 times more frequent than previously said.

In 2005, it was observed that these 15 galaxies were colliding with each other but 10 years later the current scenario looks bit surprising. It has been found that the rate of TDE has dramatically increased when there are a couple of galaxies are colliding with each other. Simultaneously, it is also has been noticed that the rate of brightness has increased by a massive amount in these 15 galaxies. Few Scientists also tried to establish other theories but most of them have a weak statement. The event is more likely to happen due to the merging of two galaxies and if it is true then it can be surely said that TDE is a more common event than it was previously thought.
