The Antennae
are undergoing a galactic collision. Located in theNGC4038 group with five other galaxies, these two
galaxies are known as the 'Antennae' because the two long tails of stars gas and dust thrown
out of the galaxies as a result of the collision resemble the antennae of an insect The nuclei of the two galaxies are joining to
become one giant galaxy. Most galaxies
probably undergo at least one significant collision in their lifetimes. This is
likely the future of our Milky Way when it collides with the Andromeda galaxy Two supernovae have been discovered in the galaxies: SN 2004GT and SN 2007sn.
A recent study finds that these interacting galaxies are
closer to the Milky Way than previously thought—at 45 million light-years
instead of 65 million light-years.

Background-ul e foarte verde iar galaxiile sunt foarte mov, pentru gustul meu cel putin :) Sunt foarte multe imagini super in arhiva care nu au mai fost niciodata procesate si aratate publicului.
