DELTA (8) corvi 5 A double star with components of unequal magnitudes, 3rd and 9th, divisible with small telescopes.

NGC 4038 and NGC 4039 (THE ANTENNAE) 5 S

3 A remarkable pair of interacting galaxies. A major "traffic accident" is happening, 65 million light-years away, as the galaxies NGC 4038 and 4039 collide with each other. At 10th magnitude, the galaxies are too faint to see with small telescopes, but photographs reveal their true structure. Stretching away from them on either side are two antenna-like arcs, consisting of plumes of gas and millions of stars that have been flung into intergalactic space as a result of this collision.

the antennae

As the galaxies NGC 4038 and NGC 4039 sweep past each other, gravity draws out long streams of stars and gas, seen extending like the antennae of an insect, hence the object's popular name.

These include the closest star to the Sun, the brightest globular cluster, and a peculiar galaxy.
