Because of their age, elliptical galaxies are believed to have older stars and less gas and dust in their insterstellar medium than other types of galaxies, and thus their nebulae are less common. However, nebulae are presumed to exist in almost all galaxies; and some recent observations hint that the central black holes of elliptical galaxies may tend to preserve interstellar gas by preventing it from cooling enough for star formation.
What else can I help you with?
What galaxies are nebulas found?
Nebulas are found in all types of galaxies, including spiral galaxies like the Milky Way, elliptical galaxies, and irregular galaxies. They are regions of dense dust and gas where new stars are formed. The variety of shapes and sizes of nebulas contribute to the diversity of galaxies in the universe.
Which galaxy is bigger a elliptical or irregular?
Elliptical galaxies are typically larger than irregular galaxies. Elliptical galaxies are shaped like ellipsoids and often contain more stars and stellar mass compared to irregular galaxies, which have a more irregular and chaotic shape and structure.
What are some physical characteristics of elliptical galaxies?
Elliptical galaxies are generally round or oval in shape, lacking the distinctive spiral arms seen in spiral galaxies. They typically have a smooth and featureless appearance, with older star populations and little ongoing star formation. Elliptical galaxies also tend to be more massive and contain mainly older stars.
Why some elliptical galaxies are lens shaped where as others are quite spherical?
Very lens-shaped elliptical galaxies have a high amount of reddish stars. Hence both their shape (the "spiral arms" have pulled inward over time) and the color of the stars implies they are very old galaxies. Spherical galaxies - I'm not up enough on that topic, so I will leave that part of the answer to another.
There are more spiral galaxies than elliptical?
the elliptical galaxy has a round or oval shape the spiral galaxy has a hurricane shape The origin of these different shapes would lie in the particular momentum of the constituent stars at the time they first coalesced into a galaxy under their mutual gravitational attraction.
What galaxies are nebulas found?
Nebulas are found in all types of galaxies, including spiral galaxies like the Milky Way, elliptical galaxies, and irregular galaxies. They are regions of dense dust and gas where new stars are formed. The variety of shapes and sizes of nebulas contribute to the diversity of galaxies in the universe.
Is it true that elliptical galaxies are sometimes called dwarf galaxies?
You can have dwarf elliptical galaxies.
Who proved that there are galaxies besides the milky way?
Hubble, in his studies of Nebulas which turned out to be galaxies.
What is three dimensional galaxies that can be shaped like a football that can be shaped like a football?
I think elliptical galaxies are the galaxies you are referring to. Scientist normally describe them as a flatted disk shape. These galaxies contain mainly older stars.
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
What is one way that an elliptical galaxy differs from the other types of galaxies?
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
Are elliptical galaxies very bright and old?
Elliptical galaxies are generally old but not very bright
Do elliptical galaxies have gas and dust?
elliptical galxies
What are football shaped galaxies called?
They are elliptical galaxies.
The types of Galaxies?
Spiral,elliptical,and irregular galaxies
Are there at least 15 billion elliptical galaxies in the universe?
There are at least 15 billion elliptical galaxies in the universe.
