Nasa called the images "a treasure trove of cosmic delights"

Nasa has revealed some new images from its Chandra telescope, and they are incredible.

The images are of galaxies, stars, planetary nebulas and supernova remnants.

They are not photographs, the colourful images have been put together using data from Chandra and other sources.

M82

M82 is a galaxy that is "oriented edge-on to Earth".

Cartwheel Galaxy

This galaxy was discovered in 1941 by Swiss astronomer Fritz Zwicky, who said it was "one of the most complicated structures awaiting its explanation on the basis of stellar dynamics."

And it's huge - 150,000 light years in diameter to be precise!

Helix Nebula

The Helix Nebula, which is in the constellation Aquarius, is actually a star running out of fuel. The same thing could happen to our Sun in five billion years' time.

A nebula is basically an interstellar cloud of dust, hydrogen, helium and other ionized gases.
