Cape Town-The MeerKAT radio telescope outside Carnarvon made another exciting discovery.

In a discovery described by scientists as “very rare,” two giant radio galaxies were discovered by the MIGHTEE survey, one of the facility’s projects.

A radio galaxy is a galaxy with a supermassive black hole in its center.

As the interstellar gas falls towards the black hole, it becomes active, releasing large amounts of energy from this region.

Dr. Jacinta Delhaize, a postdoctoral fellow at the University of Cape Town, is the lead author of this study.

“These are staring at the universe far from the center of the galaxy, where supermassive black holes and stars are located. They are shining, but not the optical light we see. Radio light. Why do we call these radio galaxies? “

Delhaize explains why this discovery is so important.

“The galaxies we found are 93% larger than any other giant we have ever found. They are absolutely huge, 62 times larger than the Milky Way. About 6.5 million from one end to reach. It takes light years. The other end. They are really huge. “
