Where is the NGC 6300 located?

NGC 6300 is located in a starry patch of sky in the southern constellation of Ara (The Altar) which contains a variety of intriguing deep-sky objects. NGC 6300 has beautiful pinwheeling arms connected by a straight bar that cuts through the middle of the galaxy. While it may look like a standard spiral galaxy in visible-light images like this one, it is actually a Seyfert II galaxy. Such galaxies have unusually luminous centres that emit very energetic radiation, meaning that they are often intensely bright in part of the spectrum either side of the visible. NGC 6300 is thought to contain a massive black hole at its heart some 300 000 times more massive than the Sun. This black hole is emitting high energy X-rays as it is fed by the material that is pulled into it. This image of NGC 6300 was taken by the ESO Faint Object Spectrograph and Camera (EFOSC2) on the 3.58-metre New Technology Telescope (NTT). Image: ESO/C. Snodgrass
