Why are elliptical galaxies red?Question:Why are elliptical galaxies red?Elliptical Galaxy:Elliptical galaxies have an overall shape resembling smooth, oblong blobs. This shape is believed to occur when smaller galaxies merge, losing their defined structures in the process.Answer...
Why are elliptical galaxies red? Why do gas planets have different colors? Why do planets revolve around the sun? Why are dwarf planets important to astronomy? Why does Jupiter have so many moons? What distinguishes a nebula and a star?
IT has long been knownthat the flattest elliptical galaxies observed are of type E7, corresponding to an axial ratio of 3.33:1 whereas SO and spiral galaxies are seen with axial ratios up to 20:1. We show, using Maclaurin spheroid models, that an initially spherical protogalaxy, composed ...
For example, the younger age of disk galaxies is corroborated by their blue color. Blue stars are generally larger, and they burn faster and hotter (blue light has a higher frequency and is thus more energetic than red light). Meanwhile, elliptical galaxies are filled with older stars — cal...
(home of Sagittarius A*). Right: As a super giant galaxy, M87 is visible to the naked eye from 54 million light years away. But as an elliptical galaxy, it looks like a smudge on the lens. That tiny blue tail is a jet of plasma (one of two) that’s...
From the ISS, only continents and oceans are significant. Farther away, only planets and stars. Farther still, only entire galaxies. The same concept applies when you zoom out on the history of life (which we did once, in this post). To make the daily news, an event can be the ...

Why are there no planets in the asteroid belt? Why is Jupiter an outer planet? Why are elliptical galaxies red? What is Comet ISON? Does Comet Halley have an ion tail? Why does a star become a red giant? How does gravity affect Comet Hale-Bopp?
Why are stars red in the red giant phase? Why is X-ray astronomy done with telescopes in space? What is the purpose of a solar telescope? When is the sun highest in the sky? Why is a star cluster with many colors young? Why are elliptical galaxies red?
Explain why sunsets are red. Why does rotating a Michelson Morley interferometer 90 degrees produce a fringe change? Why are the shells visible around some elliptical galaxies significant? Why does nuclear fusion in the sun only occur near the center?
