Beauty lies in the eyes of beholder

Incredibly bright isolated star in a nearby galaxy, VFTS 682, is three million times brighter than the Sun and was spotted during a survey of the most brilliant stars in and around the Tarantula Nebula in the Large Magellanic Cloud.

Tiny green crystals, called olivine, thought to be raining down on a developing star. This picture was taken in infrared light by Spitzer and the arrow points to the embryonic star, called HOPS-68.

The olivine crystals are suspected to have been transported into the outer cloud around the developing star, or protostar.

This picturesque group of interacting galaxies is called Arp 273. The larger of the two galaxies, called UGC 1810, has been distorted by the gravitational tidal pull of its smaller neighbour, UGC 1813. The blue lights across the top of the larger galaxy are from clusters of intensely bright and hot young blue stars. Arp 273 lies in the constellation Andromeda and is roughly 300 million light-years away from Earth.

This is the variable star that changed the thinking of modern astronomy. The star, in the Andromeda galaxy, was discovered by Edwin Hubble in 1923 and it proved that there were galaxies beyond our own Milky Way. Previously it was thought that the Milky Way was the sum total of the entire universe and areas like Andromeda were known as spiral nebulae. Hubble's discovery showed that Andromeda was beyond our galaxy, therefore proving there was more than one galaxy in the universe. This image shows the iconic star and was captured by the Hubble Space Telescope, named after the man who made this historic discovery.

"Hoag's Object" galaxy is known to have some rare and inexplicable traits, not the least of which is the "halo" of stars surrounding its core.
