The Hand of God: A small, dense object only 12 miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years Its colours stretching across the inky blackness of outer space this curiously shaped galaxy has been sighted 25 million light years away.
Its technical name from Nasa researchers is NGC 463 but others have likened it to the Cosmic Herring or The Whale Galaxy.
In this gorgeous colour image, the galaxy's yellowish core, dark dust clouds, bright blue star clusters, and red star forming regions glow brightly. It is also known to have spouted a halo of hot gas at one point.
Nasa scientists have released this stunning picture of the aptly titled Whale Galaxy. They were amazed by the galaxy's likeness to the mammal
The galaxy, which is similar in size to our own Milky Way, was found near the northern constellation Canes Venatici.
Scientists said its slightly distorted wedge shape and bright clusters made it fairly easy to find.
Using high-powered telescopes, they also found a companion galaxy, off the lower edge of the picture - the hockey stick-shaped, scientific name NGC 4656.
Nasa scientists said the distortions and mingling trails of gas and dust detected at other wavelengths suggested that these two galaxies as well as the one to the top right have had close encounters with each other millions of years ago.
