Astronomers have discovered an unknown galaxy at the edge of the universe that is forming stars at a rate of hundreds to thousands times faster compared to the Milky Way.
By the use of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers were able to capture images of the massive galaxy dubbed SDP.81, which is about 11.7 billion light-years away from our planet and is located in the Hydra constellation.
By using gravitational lens, researchers from the University of Tokyo and the“National Astronomical Observatory of Japan (NAOJ)”, were able to magnify the image and saw what appeared to be an image shaped like a ring, said the research team.
Researchers found that the monstrous galaxy called SDP.81 is forming stars at an amazing speed many times faster than the Milky Way.
The new galaxy is an example of an Einstein ring. According to Einstein’s theory of General Relativity, a massive object bends time and space. The light that travels through a curved time and spaces bends to follow the curve, which means that the massive object works like a cosmic lens.
It’s a rare case in which a distant galaxy and Earth lines up perfectly, making the image look like a circle of light, known as the Einstein ring.
The clouds spotted in SDP.81 are about the same size as that of the other galaxy, that includes the Milky Way.
This is the first time astronomers were able to reveal and understand the inner structure of a galaxy located so far away.
The model found also indicates the existence of a “supermassive black hole”, more massive by 300 million times than the Sun.
