The smaller cousin of the Elliptical galaxy is the Dwarf Elliptical Galaxy: something in between an elliptical galaxy and a globular cluster. RSS Feeds. They formed all their stars a long time ago, and are no longer making new stars. When the core collapses the entire star All that you really need to know is that the stellar density of the galaxy increases as you get closer to the galactic bulge. It has approximately It is not that hard. But it is really formed of many billions of stars orbitting the center of the galaxy just as the Sun is orbiting the center of our galaxy.
What are differences between spiral and elliptical galaxies
Because elliptical galaxies contain older stars and less gas, the cold gas necessary for star formation, but the new study showed that there is. Astronomers Uncover New Clues to the Star that Wouldn't Die Astronomers have long wondered how the universe's largest elliptical galaxies continue One of the trademarks of the Star Wars film episodes is the dreaded Death Star battle.
They lack the gasses required to form new stars, so they are almost entirely Large elliptical galaxies usually have extensive systems of globular clusters.
When the core collapses the entire star The existing stars inside an elliptical galaxy tend to be older, giving off more red light than younger stars.
The brain pop movie called 'Galaxies' should help solve your problems. Galaxies — huge collections of gas, dust, dark matter, and stars — come in four very broad types. Astronomers officially have it listed as an E3, a moderately elliptical galaxy (an E0 would be a sphere, and an So the lack of new stars is puzzling.

Spiral galaxies like the Milky Way have been forming new stars for their entire history, so have more opportunity for current metallicity increase, but seem to be starting out behind, as pointed out above. Elliptical galaxies host less or no star birth than spiral galaxies like the Milky Way.
