OBJECT DESCRIPTION AND IMAGE SESSION
Although NGC 2997 seems to be face on, is in fact tilted by about 45º. This galaxy has a small nucleus surrounded by a chain of hot giants clouds of ionized hydrogen and also by prominent dark lanes which are also visible in the image. It is the brightest galaxy of Antila and it has a mass equivalent to 100 billons times our Sun. NGC 2997 is speeding away from our Milky way at about 1100 kilometres per second.
This galaxy has a very low surface brightness and is surrounded by bright stars and a relative populated star background.
