| Object type: | Emission Nebula | ||
| Size: | |||
| Magnitude: | 6 | ||
| Constellation: | Perseus | ||
| Distance: | 1,000 light years | ||
| Notes: |
This nebula stretches nearly 2.5 degrees. Hβ radiation from
nearby young energetic O7.5 III giant, Xi Persei excites the surrounding
gases. The shape of the ionized gas clouds resembles the state of California. In
this image, Xi Persei (aka Menkib) is the very bright white star above and
to the right of the OIII coud. |
