||NGC 4038 + NGC 4039, The Antennae,
The Ringtail Galaxy
||Colliding galaxy pair
||12 h 02 min
-18° 30' (Corvus)
||A cosmic embrace 60 million light
years away. Shorter exposures show the brightest features of these
interacting galaxies as a mirrored question mark or a ringtail.
There are two filaments that give the galaxy pair its other popular name.
They emit strongly in radio wavelengths and were
created by the tidal forces of the collision process. These forces also
trigger new star forming regions.
A wider field, showing more of the filaments, can be found here.
