On 7th of February in 1785 William Herschel dicovered this impressive example of interactive galaxies. NGC 4038+39 are located in the constellation "corvus" and make a beautiful view in a decent telescope, as they are rather brightly shining around 10m4.

The light we see in this image was dispatched by the galaxy some 88 Mio years ago and we see now might have changed significantly meanwhile, as the process of interaction between galaxies is quite huge. Whenever galaxies merge they exchange their supplies of hydfrogen, yielding in massive "star-production".

However, if you want to see the galaxies visually through a telescope, you will have to travel far south. Best spot would be on the southern hemisphere. Andrey Oreshko's remote observatory location is perfectly situated in the Atacama desert, providing excellent conditions to image the socalled "Antenna-galaxies".
