a colorful cloud of gas that glows because it is heated by light from nearby hot stars
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
A nebula. That's composed mostly of hot gasses. Hence, the name. Hot nebula.
ionization potential energy. but remember the atom must be neutral .
Mercury's ionization energy is 24.10
Argon's ionization energy is 39.948
a large elliptical galaxy
Emission Nebula is an ionized gas cloud that shines in various colors. Its ionization is from the high energy proton released by its neighboring star.
The location of the nebula is in many places because the nebula exists in different constellations. A nebula is a cloud of interstellar dust.
The Crab Nebula is a nebula.
Triffid Nebula, Eagle Nebula, Cat's Eye nebula
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
nebula
It all depends on how close stars are to the cloud, and how intense those stars radiate energy. A nebula will glow with a blue colour if it simply reflects starlight (the blue is from the same mechanism our sky is blue, from the scattering of light). This occurs when a nebula is too far from stars, or the stars are too cool to generate enough radiation to ionize the hydrogen. Nebula will glow red if they are close enough to stars to absorb energy - that energy is re-emitted by the nebula as red (from the ionization of the hydrogen, which then glows red).
The Stingray Nebula (Hen 3-1357) is a planetary nebula. (The youngest known).
Within regions of active star formation; near hot stars. The colorful glowing blob is a result of the surrounding gas absorbing ultraviolet photons from the hot stars.
a type of nebula
"The Crab" is a nebula.
