10 NASA wallpaper images of Galactic 'Fossil'

NASA's Roman Space Telescope captured this image of Galactic 'fossils', which are ancient stars that provide clues about how galaxies formed and evolved.

This image shows two simulated galaxies in the early stages of a collision that will  throw many stars from both galaxies into wide orbits, creating a faint stellar halo around the larger galaxy.

The Antennae galaxies, also known as NGC 4038 and NGC 4039, located in the Corvus constellation, are a pair of spiral galaxies that are colliding and fusing together.

NASA's Hubble Space Telescope captured this stunning image of giant elliptical galaxy NGC 1316 which is about 60 million light-years away in the constellation Fornax.

The Centaurus A, also known as NGC 5128, is a galaxy in the constellation of Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta, Australia.

The NGC 5866 is a lenticular galaxy in the constellation Draco. It lies in the Northern constellation Draco, at a distance of 44 million light-years away from the Earth.

NASA's this image shows the intersecting pair of galaxies knows as Arp-Madore 2339-661. The two intersecting galaxies are NGC 7733 and NGC 7734.

The peculiar spiral galaxy ESO 415-19, which lies around 450 million light-years away, stretches lazily across this image from the NASA/ESA Hubble Space Telescope.

This image also shows head-on collision between two galaxies. The interacting galaxy duo is collectively called Arp 143.

This image of Messier 82, also known as NGC 3034, Cigar Galaxy or M82, is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major.
