Although it is the closest known satellite galaxy to the center of the Milky Way, pushing the Sagittarius Dwarf Elliptical (SagDEG) into … Being this close, it is rather surprising that the galaxy was only discovered by an international team of professional astronomers in 2003, although it must be stated that this galaxy lies in the galactic plane, and is therefore largely obscured by dust clouds. NGC 2359 - is an emissions nebula - is about 30 light years in size - roughly 15,000 light years away 2 Myths: 1. Nevertheless, based on various properties of the cluster, as well as measurements of the movements of stars within it, M41 is expected to have totally dispersed in another 300 million years or so.

The supposed small galaxy contains a relatively high percentage of red giants, and is thought to contain an estimated one billion stars in all. NGC 1261 is another nearby cluster, but its velocity is different enough from that of the others to make its relation to the system unclear. Although closer to the Earth than the centre of the galaxy itself, the Canis Major Dwarf Galaxy was difficult to detect as it is located behind the plane of the Milky Way, where concentrations of stars, gas and dust are densest. Canis Major may be only the 43rd biggest of the 88 recognized constellations, but it does have the distinction of containing the night sky’s most luminous star, Sirius, a double star situated 8.6 light years away with a visual magnitude of -1.24.

This is closer than the Sagittarius dwarf galaxy, discovered … At only 25,000 light-years away from the Solar System, it is even slightly closer to us than the core of our own galaxy. Nevertheless, our results suggest that the 2MASS M giant overdensity previously claimed to represent the core of a dwarf galaxy in Canis Major (l~240 deg) is an artifact of a dust extinction window opening to the overall density rise to the more significant Argo structure centered at larger longitude (l~290 deg +/-10 deg, b~-4 deg +/-2 deg).
