SPACE — There are many hidden mysteries in the universe. One of them is quasars.
Quasars were first discovered 60 years ago. Even though it was discovered 6 decades ago, this object is still a mystery until now.
Quasars are the brightest and most powerful objects in the universe. Now, new research suggests how quasars can form.

According to recent research published in the journal Monthly Notices of the Royal Astronomical Society, quasars can form when galaxies collide. As the brightest objects in the universe, quasars can be a trillion times brighter than the Sun.
Scientists led by the Universities of Sheffield and Hertfordshire analyzed data from the Isaac Newton Telescope in La Palma. They found what they described as the “presence of distorted structures” in galaxies containing quasars.
Clive Tadhunter, scientist at the University of Sheffield’s Department of Physics and Astronomy, said quasars are one of the most extreme phenomena in the Universe.
When galaxies collide, the gas produced is pushed towards the black hole. These events release tremendous energy in the form of radiation, producing the characteristic brilliance of quasars.
Scientists compared observations of 48 quasars and their host galaxies with images of more than 100 non-quasar galaxies.
The team concluded that galaxies that harbor quasars are roughly three times more likely to interact or collide with other galaxies.
Dr Jonny Pierce, postdoctoral research fellow at the University of Hertfordshire, said quasars were one of the objects that scientists around the world wanted to study further. The James Webb Space Telescope was able to study the earliest galaxies in the Universe.
The Webb telescope is able to detect light from even the most distant quasars, which were emitted nearly 13 billion years ago.
“Quasars play a key role in our understanding of the history of the universe, and possibly the future of the Milky Way,” said Pierce. BelfastTelegraph.
