The Hubble Space Telescope captured a stunning image of galaxy that's hiding a secret.

The spiral galaxy is known as NGC 4651, and although it looks relatively calm and quiet swirling out in deep space, the European Space Agency says it harbors a "violent secret."

"It is believed that this galaxy consumed another smaller galaxy to become the large and beautiful spiral that we observe today," the ESA explains in a blog post with the image.

Pictures this clear are only possibly thanks to the powerful NASA/ESA Hubble Space Telescope, but the cannibal galaxy can be seen with an amateur telescope, too.

"If you have a telescope at home and a star-gazing eye, look out for this glittering carnivorous spiral," the ESA advises.

NASA releasd a beautiful image of the Rosetta Nebula on Thursday.
