The image was captured by The Event Horizon Telescope Group. Now get this -- it's located 27,000 light-years from planet Earth. Put another way ... as enormous as this hole is ... when you look up in the sky with a naked eye, it looks about as big as a donut on the moon. Wrap your head around that!!!

The hole is at the center of our galaxy and near the constellation Sagittarius. It is, indeed, supermassive. You want your mind blown again ... its mass is equal to 4 million suns!!!

It's being described as "the glue that holds the galaxy together."  As for how black holes are created ... it's when a gravitational pull is so intense nothing -- even light -- can escape.

This image was released days after NASA showed off super clear images of stars ... courtesy of the James Webb Space Telescope.

The $10 billion telescope is just beginning its work, which should unlock some of the mysteries of our universe.
