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.
Images taken in infrared and visible light by NASA's Hubble Space Telescope recount a vivid story of the turbulent birthing process of massive stars. The pictures show that powerful radiation and high-speed material unleashed by "hefty" adult stars residing in the hub of the 30 Doradus Nebula are triggering a new burst of star birth in the surrounding suburbs.
