How old are irregular galaxies?
Which are older spiral or elliptical galaxies?
When was the first elliptical galaxy discovered?
Can life exist in an elliptical galaxy?
Are the 6 galaxies too old to exist?
#HubbleFriday Elliptical galaxies tend to be full of old stars and exhibit little or no new star formation. Messier 59 bucks this trend somewhat; the galaxy does show signs of star formation, with some newborn stars residing within a disk near the core: https://t.co/GzUYX5DoDY pic.twitter.com/TqTBfneA7R— Hubble (@NASAHubble) May 31, 2019

Where are elliptical galaxies mostly found?
Why are elliptical galaxies older?
How did you determine elliptical galaxies?
- How old are elliptical galaxies?
- Between 7 and 10 billion years old The accepted belief on the mass assembly history of massive elliptical galaxies based on their stellar population leads to an age between 7 and 10 billion years old.
- Who discovered that the Earth is elliptical?
- Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He gave three fundamental laws of planetary motion. He also did important work in optics and geometry.
- What is the ex of the elliptical galaxy?
- Cygnus A - located about 600 million light-years from Earth. This galaxy is an extremely bright radio source in the universe. M87 - a giant elliptical galaxy that is located near the center of the Virgo cluster.
- What created the elliptical galaxies?
- Elliptical Galaxies The stars orbit around the core in random directions and are generally older than those in spiral galaxies since little of the gas needed to form new stars remains. Scientists think elliptical galaxies originate from collisions and mergers with spirals.
- How big is the average elliptical galaxy?
- Elliptical galaxies vary greatly in both size and mass with diameters ranging from 3,000 light years to more than 700,000 light years, and masses from 105 to nearly 1013 solar masses. This range is much broader for this galaxy type than for any other.
- What galaxy contains the oldest stars?
- Elliptical Galaxies Elliptical Galaxies The stars orbit around the core in random directions and are generally older than those in spiral galaxies since little of the gas needed to form new stars remains.
- How are the stars arranged in an elliptical galaxy?
- The stars in an elliptical galaxy are often close together, making the center seem like one giant star. If the Earth were inside an elliptical galaxy, the amount of light coming from the surrounding stars would mean that it would be bright all the time, no day and night.
How old are the stars in an elliptical galaxy
|What is the structure of the elliptical galaxies?
|Elliptical galaxies have a smooth ellipsoidal or spherical appearance, and they have far less structure than spiral galaxies do. Elliptical galaxies are typically found in galaxy clusters.
|What are the stars in the elliptical galaxies?
|In general, the stars in elliptical galaxies are old, red stars. These galaxies look the same from all angles, too. Astronomers used the ages of the red stars in the elliptical galaxies to determine that these galaxies are pretty old. Maybe they were spirals once with gas and dust in spiral arms.
|How are elliptical galaxies held together?
|What is in an elliptical galaxy? An elliptical galaxy is a collection of gas, dust, and stars held together by gravity.
|How are stars arranged?
|Most multiple-star systems are organized in what is called a hierarchical system: the stars in the system can be divided into two smaller groups, each of which traverses a larger orbit around the system's center of mass.
|Are elliptical galaxies made of old stars?
|Instead of spiral arms, elliptical galaxies are just big clumps of stars. There is very little gas and dust. Because there is not much gas and dust, there's not enough material to make new stars. In general, the stars in elliptical galaxies are old, red stars.
|Are elliptical galaxies younger?
|The typical ages of the stellar populations of elliptical and spiral galaxies provide evidence for this theory, because the stars in elliptical galaxies are typically much older and redder than those in spiral galaxies.
- Which galaxy shape has the oldest stars?
- Elliptical Galaxies The stars orbit around the core in random directions and are generally older than those in spiral galaxies since little of the gas needed to form new stars remains.
- What do elliptical galaxies contain?
- Most elliptical galaxies are composed of older, low-mass stars, with a sparse interstellar medium, and they tend to be surrounded by large numbers of globular clusters.
- What is an elliptical galaxy typically composed of?
- Elliptical galaxies have an even, ellipsoidal shape. They typically contain a much greater proportion of older stars than spiral galaxies do. Four classes are used to classify galaxies: spiral; barred spiral; elliptical and irregular.
- What would you see in a elliptical galaxy?
- Elliptical galaxies have shapes that range from completely round to oval. They are less common than spiral galaxies. Unlike spirals, elliptical galaxies usually contain little gas and dust and show very little organization or structure.
- What do normal elliptical galaxies contain?
- In fact, elliptical galaxies contain primarily old, red stars (also known as Population II stars). Elliptical galaxies vary widely in size. Both the largest and the smallest known galaxies are elliptical.
- Where did elliptical galaxies come from
- Current thinking amongst astronomers is that most elliptical galaxies formed from the collisions and subsequent mergers of spiral galaxies. The typical ages of
