Helix Nebula (God’s Eye) By Troy Korb

Helix Nebula Also called God’s Eye, or NGC 7293 It is the closest nebula to Earth It is only about 213 Parsecs (690 Light years) away It is debated on how far away it actually is, somewhere between 450 to 650 to 690 light years It lies with in the Aquarius Constellation

Helix Nebula It is a Planetary Nebula Means it could create planets It is about 287 Arcminutes (5.6 Light Years, or 1.7 Parsecs) across

Structure It is thought to have a complex structure Almost as if It had two disks nearly perpendicular to each other Can not be all that sure because the Hubble only takes 2-D pictures Its color comes mostly from hydrogen (red outer disk) and oxygen (blue outside of inside disk)

Tentacles It seems to have tentacles pointing to the white dwarf star (in the blue and red parts) It is thought to be created by hot stellar wind plowing into colder shells of dust and gas The tentacles are almost comet like They have been observed from Earth for a long time, but never up close
