NGC 6142 (also MCG 6-36-41, UGC 10366 and PGC 57984) is a magnitude +13.8 spiral galaxy located 470 million light-years away in the constellation Corona Borealis. The galaxy was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflector at Winds...
NGC 2298 (also ESO 366-SC22 and GCL 11) is a magnitude +9.3 globular star cluster located 35200 light-years away in the constellation Puppis. In 2003 it was discovered that NGC 2298 may have come from the Canis Major Dwarf galaxy. NGC 1851, Messier 79, NGC 1851 and NGC 2808 may have a similar origin. Th...
The M4.5V flare star AF Psc as seen in K2 engineering data We present the light curve of the little studied flare star AF Psc (M4.5V) obtained using engineering data from the K2 mission. Data were obtained in Long Cadence mode giving an effective exposure of 29 min and nearly 9 d of coverage. A clear modu...

Title: The Serpens Molecular Cloud Authors: C. Eiroa, A.A. Djupvik, M.M. Casali The Serpens cloud has received considerable attention in the last years, in particular the small region known as the Serpens cloud core where a plethora of star formation related phenomena are found. This review summ...
The 13 - 30 metre wide asteroid 2014 KF46 will make a close pass (1.6 lunar distances, 0.0041 AU), travelling at 17.08 km/second, to the Earth-Moon system on the 29th May 2014 @ 00:24 UT ±00:01. See more The Lunar Distance (LD), the distance between Earth and the Moon, equals 384,401 km, (or 0.00256 AU)...
Asteroid (951) Gaspra is an S-type asteroid that orbits very close to the inner edge of the main asteroid belt. Gaspra was the first asteroid ever to be closely approached when it was visited by the Galileo spacecraft, which flew by on its way to Jupiter on 29 October 1991. Read more [video=http://ww...
