What are the causes of reflection nebulae?
Reflection nebulae are some of the most hauntingly beautiful sights in space.They are caused by some massive hot young stars being close to, or embedded inside, a gas cloud.
Blue is typically dust scattering, though it can also be highly excited oxygen or hydrogen.More items…•.
What is the reflection nebula made of?
A reflection nebula is a cloud of gas and dust which does not create its own light, but instead shines by reflecting the light from nearby stars. The brightest reflection nebulae are places where new stars are being formed. Here the gas and dust is thick and shines by the light of new, bright stars.
How do emission and reflection nebulae differ?
An emission nebula is a cloud of ionized gas. The most common source for ionizations are high energy photons emitted from a nearby star. … Reflection Nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars.
What causes a dark nebula?
The dark nebulae are clumps or clouds that become opaque because of their internal dust grains. The form of such dark clouds is very irregular: they have no clearly defined outer boundaries and sometimes take on convoluted serpentine shapes.
What does a reflection nebula look like?
Reflection nebula. A reflection nebula is a cloud of interstellar gas and dust that reflects the light from other stars. … Reflection nebulae mostly appear to have a blue colour. This is because particles in the nebula scatter (or reflect) blue light more efficiently than they scatter red light.
What is inside a planetary nebula?
A planetary nebula, abbreviated as PN or plural PNe, is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. … All planetary nebulae form at the end of the life of a star of intermediate mass, about 1-8 solar masses.
