Scientists have captured a beam of plasma ejected from a black hole at near the speed of light during a galactic collision.
The “monster” black hole is located at the center galaxy RAD12 and its giant plasma beam bombarded neighboring galaxy RAD12-B. The two are located about a billion light years from Earth and are in the process of merging. This is the first time a jet plane has emerged from one galaxy and collided with another. Space reported on October 16.
Aerojets, composed of ionized gases and electrons, are often observed in pairs and moving in opposite directions at speeds close to the speed of light. What makes RAD12’s case unique is that its black hole appears to only eject a jet of plasma toward RAD12-B. This strange phenomenon still remains a mystery to scientists.
The research team believes that decoding this mystery will help us better understand the process of star formation in the universe. galactic merger eventbecause we know that jet streams chase cold air and create waves “building blocks” for the birth of new stars.

Observe collision between RAD12 and RAD12-Bastronomers used the giant GMRT radio telescope in India combined with data from many other telescopes, such as the MeerKAT radio telescope – a combination of 64 antennas – in South Africa’s Meerkat National Park.
According to Ananda Hota, leader of the research team and assistant professor in the Department of Atomic Energy at the University of Mumbai in India, the cone-shaped jet ejected from the black hole at the center of RAD12 extends up to 440,000 light years, longer than its host. galaxy, and moved far enough to collide with the neighboring galaxy GMRT.
Hota noted that this discovery also benefited from great contribution from thousands of students and citizen scientists across India. Details of the study were published in the journal Monthly notices of the Royal Astronomical Society: letters.
