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 ...
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 and Explanation: Because galaxy collision takes a very long time, elliptical galaxies are very...
Why are elliptical galaxies red? Why is dark matter essential to galaxy formation? Where did light pollution start? How does the planetary nebula shine? Does the moon cause light pollution? Why is Jupiter a planet? Why is Jupiter no longer a planet?
Elliptical orbits are the result of multiple forces acting upon a body in motion. When the Earth soon comes closer to Mars than in 60K years they will interact and the result will be measureable. , though we will feel nothing. Telescopes show that all gala...
Any two particles attract one another, as do any two galaxies. Of course, at large enough distances, the attraction becomes so small as to be effectively zero. Given how important gravity is to describing how all matter interacts, the colloquial English definitions of gravity (ac...
Not only might we be on the cusp of the great leap of life becoming multi-planetary, we may be on the cusp of a bunch of other great leaps as well. There are other signs pointing to this being an extraordinarily unusual time to be alive: For 99.8% of human history, the world ...

How did the Comet Hale-Bopp get its name? What is the purpose of the Oort cloud? 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 are large astronomical bodies such as planets and stars round? Why does Venus have no moons? Why do all gas planets have rings? Why are binary stars useful to astronomers? Why do galaxies spiral? Why does an elliptical galaxy look like one giant star?
Why was Kepler able to deduce the elliptical orbits of planets from Tycho's data, while so many other earlier astronomers and learned men had missed it? Why will Polaris not always be the North Star? What is the purpose of planetary science?
