What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
Why doesn't the Horsehead Nebula glow like other nebulae?
Horsehead Nebula doesn't glow like other nebulae because it is older than other nebulae and was probably a lot smaller. In addition, Horsehead Nebula is farther away from the Earth than other nebulae, so it may seem that it doesn't glow as bright as other nebulae. No, this isn't right! The horsehead nebula doesn't glow for one reason - it isn't illuminated by any stars whose energy is enough to make the gas shine. That's the only difference between a 'bright' diffuse nebula (like M42) and a 'dark' one like the Horsehead or the Coalsack. M42 (the Orion nebula) is bright because there are several hot, energetic stars embedded inside it, and which cause it to 'shine'.
Why do emission nebulae appear red when they surround blue stars?
The color of emission nebulae is a result of the predominate gas or gasses in that nebulae. Different gasses glow in different colors. Blue, as the color of the star, indicates how hot the star is.
What makes Aurora borealis glow?
Energy coming from the sun.
What is the iridescent coat on the retina that makes animal's eyes glow green at night?
Tapetum lucidum

What are the glowing clouds in space?
The glowing clouds that you see in pictures from space are called emission nebulas. A emission nebula is a cloud of hot, glowing cloud of gas and dust in space. These nebulas absorb the light of nearby stars and reach very high temperatures. The high temperature causes them to glow. Emission nebulas are often found in regions of space where new stars are forming.

What color will an interstellar gas cloud composed of hydrogen glow?
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).
What makes watch face glow?
hi how you get back your face glow
How do you use bioluminescence in a sentence?
"Bioluminescence is the biochemical emission of light by living organisms such as glow-worms and deep-sea fish..."
Why do yellow highlighters tend to have a glow?
This is because it contains phosphor, a chemical that makes things glow. Take note: All elements glow but only phosphor is in the visible range.Phosphorus is the chemical element that has the symbol P and atomic number 15.Phosphorus compounds are used in explosives, nerve agents, friction matches, fireworks, pesticides, toothpastes, and detergents.Phosphorus doesn't actually glow, it converts light into heat. All elements have this effect, but phosphorus' light emission is in the visible range.
Which of the following processes depend on spontaneous radioactive decay?
the process of bone-scan imaging, using radiometric dating, radium paint that makes watch dials glow in the dark using carbon-14 to determine fossil ages
Who makes a quality glow in the dark clock?
GE makes some excellent glow-in-the-dark clock, which go well in children's rooms.
Why are some nebula's hard to see?
"although some nebulas glow or reflect starlight, others absorb light and so are too dark to see."
