(Sorry this isn't all scientific) The radiation given off stars illuminates the gas and dust in the galaxy revealing a pattern or shape
the stardust and hot gas that is produced by an internal nuclear fusion process. Thank you for coming to me for an answer. Sincerely, Answers.com
fluorescent lights
Electric current through a filament (thin spiral) of tungsten causes it to heat up enough to glow brightly.
yes actually glow worms have a chemical reaction in their behind and this causes a glow this glow attracts other insects towards the glow worms so that they can eat them
the computer tells it to glow.
Timing is slowed.
Stars glow because they are hotter than the surrounding area. See related question.
To create a model of the Milky Way galaxy, you can start by using a large circular base to represent the galactic disk, and then add smaller foam balls or beads to indicate stars, with denser clusters for star-forming regions. Use a central sphere to represent the supermassive black hole at the galactic core. Optionally, you can add strands of wire or string to represent the galaxy's spiral arms, and paint the entire model to reflect the colors and features of the galaxy. Finally, display it with a light source to mimic the glow of stars.
The Horsehead Nebula is located in the Orion constellation, specifically within the Orion Molecular Cloud Complex. It lies approximately 1,500 light-years away from Earth and is part of the Milky Way galaxy's Orion Arm, which is a minor spiral arm. The nebula is a region of star formation, characterized by its distinctive dark silhouette against the background glow of ionized gas and nearby stars.
The atmosphere of the earth.
Yes, all of those are forms of electromagnetic radiation. The glow from a fireplace is infrared radiation, the energy within a microwave is microwaves, and a foghorn blast is sound waves, which are a type of mechanical wave that consists of both pressure waves and electromagnetic waves in the form of radio waves.
Plankton can impact waves by generating bioluminescence, causing a glowing effect known as "surf illumination." Certain species of plankton, such as dinoflagellates, produce light when disturbed, which can create a sparkling effect in the water as waves crash or boats move through the ocean. This phenomenon is often seen in areas with high concentrations of bioluminescent plankton.
