Narrowband imaging of the gamma Cygni nebula IC 1318

The Gamma Cygni nebula (IC 1318) consists of the various patches which can be seen surrounding the bright (V = 2.20) star Gamma Cygni (Sadr). Gamma Cygni is actually not part of this nebula, it is a foreground star located half way between us and the nebula. We are looking deep into the Orion Arm of our Galaxy dn24743-1_300 in this direction and the nebula is more than 3000 light years from us.

Update: A water plume has been observed at Europa (via New Scientist), and an argon-containing hydride ion found in the Crab Nebula, the first time that a noble gas molecule has been detected in space (via Physics World).

  1. I was suggested this blog by my cousin. I’m not sure whether this

    You’re amazing! Thanks!
