Density waves (they cause the spiral arms in disc galaxies).
jesus waves
Stars and galaxies emit a broad range of electromagnetic waves including visible light, ultraviolet light, X-rays, and radio waves. The specific wavelengths and intensities of these emissions depend on the temperature, composition, and activity of the celestial object.
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
All stars and galaxies are in the universe.
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
shifted to longer wavelengths, indicating that the galaxies were moving away from us. This observation led to the development of the theory of the expanding universe.
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
Five different light waves produced in the universe that we can't see include infrared radiation, ultraviolet light, X-rays, gamma rays, and radio waves. Infrared radiation is often associated with heat, while ultraviolet light can cause sunburn. X-rays and gamma rays are high-energy waves used in medical imaging and produced by cosmic events, respectively. Radio waves are used for communication and are emitted by various celestial objects, including stars and galaxies.
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
Stars and Galaxies are related because a galaxy is a system of billions of stars, gases, and dust.
Spiral arms in galaxies are believed to be caused by density waves, which are fluctuations in the density of stars and gas within the galactic disk. As stars and gas move through these waves, they become compressed, leading to the formation of new stars, which enhances the visibility of the spiral structure. Additionally, gravitational interactions with other galaxies and internal dynamics can influence the formation and maintenance of these arms. The combination of these factors results in the characteristic spiral patterns observed in many galaxies.
Bigger galaxies. And stars.
