False Comet Cluster
(Preview)
The False Comet is a group of two star clusters next to a string of brighter stars in the tail of the constellation Scorpius. The collection spans some 2 degrees of sky and looks like a small comet with a curved tail pointing northward into the Milky Way. [url=http://www.oneminuteastronomer.com/OM...

Coronet cluster
(Preview)
While perhaps not quite as well known as its star-formation cousin Orion, the Corona Australis region (containing, at its heart, the Coronet cluster) is one of the nearest and most active regions of ongoing star formation. At only about 420 light-years away, the Coronet is over three times closer t...

HO Delphini
(Preview)
The SU UMa-type dwarf nova Ho Del, is brightening again from a recent superoutburst (magnitude 15) . Outbursts of HO Del are relatively rare, with the shortest time periods of superoutbursts being about 740 days. The dwarf nova has a superhump period of 0.06453(6) days. Position(2000): 20h 36m 55s...

70 Ophiuchi
(Preview)
The nearby star 70 Ophiuchi is one of the best-known and widely studied binary star systems. It's found in an odd V-shaped collection of five stars called Poniatowski's Bull. This strange little asterism is easy to see with the naked eye from suburban skies; if you're in the city, try your finderscop...
