M29 Open Cluster in Cygnus
No galaxies or nebulae to see here. This is just an open cluster of stars, happily named M29 and sitting up there in the constellation of Cygnus.
This open cluster consists of thirty stars, the brightest of which form a "stubby dipper", giving the cluster a boxy appearance. It is about 6,000 light years away and is only 11 light years across but the five brightest stars are all giants giving the cluster the luminosity of 160,000 times that of our sun.
Watch out. This cluster is approaching us at 28 km/sec. You'd better duck when it gets here. Wear sunglasses and a high factor sunblock.
