Comment |
North at about 4:00
o'clock., the image is rotated 135° clockwise.
IC 405 (also known as
the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an
emission/reflection nebula in the constellation Auriga, about 1,500
light-years from Earth. The rippling dust and gas lanes surround the
star AE Aurigae and give the impression that the star is aflame...
hence the nebula's popular name.
The star, AE Aurigae, creates the red glow by energizing the
nebula's hydrogen. The blush areas are created by dust that scatters
and reflects the stars blue light.
