Sharpless 2-115 is an emission nebula just North and West of Deneb, in the constellation Cygnus. It displays a chaotic morphology of gas emissions and dark nebulae. In the relatively high-resolution image presented here, pillars and Bok globules can be readily identified. Adjacent to Sh2-115 is a ro...

The Lion Nebula (Sh2-132) and two bonus planetary nebulae Sharpless 132 (Sh2-132) goes by the common name of the Lion Nebula and it straddles the boundary of the constellations Cepheus and Lacerta. It is primarily an emission nebula with several embedded small dark nebulae and is estimated to be at ...

Heckathorn-Fesen-Gull 1 (HFG1, PK136+05) is a very old (~100,000 year old) and extremely faint planetary nebula in the constellation Cassiopeia. It was discovered in deep OIII images by Heckathorn, Fesen, and Gull in 1982 using the emission line survey of Parker et al (1979). The central star is a b...

Abell 78: A planetary nebula with 'born-again' progenitor star Copyright: Luca Marinelli Location: Schenectady, NY Abell 78 (PK 081-14.1, PN G 081.2-14.9) is a planetary nebula in the constellation Cygnus discovered in 1966 by George Abell. It spans 1.4 light years in diameter and is located roughl...

WR134 is a variable Wolf-Rayet star of type WN located roughly 6,000 light years from us. Its surface temperature approaches 63,000K and it is 400,000 times as luminous of the Sun. In the image, WR134 is the bright white star in the center of the oxygen bubble. WR134 is surrounded by a faint expandi...

The chaotic filamentary structure of the Cygnus Loop or Veil Nebula, a supernova remnant in the constellation Cygnus (SH2-103, SNR G074.0-08.6), is in full display in Pickering's Triangle (NGC 6979). The bubble of expanding glowing gas is what is left of a powerful explosion of a progenitor star est...

CTB 1 (Abell 85, SNR G116.9+0.1) is a faint supernova remnant in the constellation Cassiopeia. It was originally cataloged by George Abell as a planetary nebula as Abell 85 but was identified by van der Bergh, Marscher and Terzian in 1972 as a supernova remnant based on its appearance in the optical...
