The Eastern Veil Nebula

The Eastern Veil nebula (also known as Caldwell 33) is a cloud of heated and ionized gas and dust in the constellation of Cygnus and is located at around 1470 light-years from Earth. It is part of the Cygnus Loop which is a faint supernova remnant that exploded aproximately 7000 years ago. From the moment the source star exploded and until now, the Cygnus Loop supernova remnant expanded to a diameter of roughly 3° on the sky (that almost 6 full moons). The red hues in this […]

The Cygnus Loop

The Cygnus Loop (radio source W78, or Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across. Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range. Radio, infrared, and X-ray images reveal the complete loop.
