Hubble’s best. (From top to bottom, left to right)
This image of a pair of interacting galaxies called Arp 273 was released to celebrate the 21st anniversary of the launch of the NASA/ESA Hubble Space Telescope. The distorted shape of the larger of the two galaxies shows signs of tidal interactions with the smaller of the two. It is thought that the smaller galaxy has actually passed through the larger one.
The tempestuous stellar nursery called the Carina Nebula, located 7,500 light-years away from Earth in the southern constellation Carina.
The staggering aftermath of an encounter between two galaxies, resulting in a ring-shaped galaxy and a long-tailed companion. The collision between the two parent galaxies produced a shockwave effect that first drew matter into the center and then caused it to propagate outwards in a ring.
An image of a small region within a hotbed of star formation M17, also known as the Omega or Swan Nebula, located about 5,500 light-years from Earth in the constellation Sagittarius.
An image of the Eagle Nebula reveals a tall, dense tower of gas being sculpted by ultraviolet light from a group of massive, hot stars.
