description IC 2631 Overview
IC 2631 is a reflection nebula located in the southern constellation of Chamaeleon, situated within the larger Chamaeleon star-forming complex. The nebula's bluish appearance is created by starlight scattering off surrounding interstellar dust, primarily illuminated by the young stellar object HD 97300. As the brightest reflection nebula in this specific region, it is a frequent subject of study for astronomers investigating early stellar evolution and the properties of cosmic dust. It is primarily observed via astrophotography due to its faint nature.
help IC 2631 FAQ
What kind of nebula is IC 2631?
IC 2631 is a reflection nebula, meaning its visible light is scattered starlight rather than light produced mainly by glowing ionized gas. The scattered blue light comes from dust surrounding a young star.
Which star illuminates IC 2631?
The nebula is illuminated primarily by the young star HD 97300. The European Southern Observatory describes dust around HD 97300 scattering its light like headlights in fog.
Where is IC 2631 located?
It lies in the southern constellation Chamaeleon within the Chamaeleon star-forming complex. The region contains gas, dust, and young stars that are still forming.
Why does IC 2631 look blue in photographs?
Small dust grains scatter shorter blue wavelengths efficiently, producing the nebula's bluish appearance. ESO released a widely circulated image of the region in 2016 using observations from the La Silla Observatory.
