Frequently Asked Questions

FAQ

What is a space elliptical?

Elliptical galaxies are the most abundant type of galaxies found in the universe but because of their age and dim qualities, they're frequently outshone by younger, brighter collections of stars. Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies.

What is a elliptical galaxy for kids?

Elliptical galaxies range in shape from nearly spherical to very flattened and round or oval. They contain little interstellar matter. Elliptical galaxies are red in color, with their light coming mostly from old stars, especially evolved red giants. Virgo A (M87) is a notable example of an elliptical galaxy.

Are nebulae often found in elliptical galaxies?

Dust and emission nebulae are not conspicuous in elliptical galaxies, but many do contain a small amount of interstellar matter.

What is the difference between elliptical and spiral galaxies?

First, elliptical galaxies are characterized by a spherical or cucumber-like shape, while spiral galaxies have a central disk surrounded by spiral arms. Moreover, elliptical galaxies contain older, dimmer stars, while spiral galaxies are solar nurseries containing younger, brighter stars.

How does the formation of a spiral galaxy differ from an elliptical?

Unlike spirals, elliptical galaxies usually contain little gas and dust and show very little organization or structure. 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.

Why do some galaxies form an elliptical structure rather than a spiral structure?

When two spirals collide, they lose their familiar shape, morphing into the less-structured elliptical galaxies. A supermassive black hole is thought to lie at the center of these ancient galaxies. These gluttonous giants consume gas and dust, and may play a role in the slower growth of elliptical galaxies.

Where are nebulae usually found?

The space between the stars Where are nebulae? Nebulae exist in the space between the stars—also known as interstellar space. The closest known nebula to Earth is called the Helix Nebula. It is the remnant of a dying star—possibly one like the Sun.

Is elliptical the oldest galaxy?

No galaxy is older than any other, since they all formed around the same time. Ellipticals and lenticulars are more 'aged', since they have no gas and their young, blue stars have long died.

What are the ages of 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.

What is the oldest galaxy type?

Generally speaking, ellipticals are the oldest type of galaxy. An elliptical galaxy is thought to be formed by other galaxies colliding, so a spiral

When was the first elliptical galaxy discovered?

The elliptical galaxy M49 was discovered by Charles Messier in 1771. Not only was it the first object discovered in the Virgo Cluster of galaxies, but it was also the first elliptical galaxy detected outside of the Milky Way's Local Group.

Can life exist in an elliptical galaxy?

Based on numbers of stars, supernova rates, and metallicity, a prior study concluded that large elliptical galaxies contain up to 10 000 times more habitable planets than the Milky Way and are thus the 'cradles of life'.

What stars make up a spiral galaxy?

Spiral galaxies are made up of young stars, gas, and dust. You can see the dust in the dark spots of the spiral arms. The gas and dust are used to make new stars, and these baby stars glow very brightly. Astronomers use these facts to determine that spirals are typically young galaxies.

Are elliptical galaxies spiral?

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 are the characteristics of the stars that make up an elliptical galaxy?

An elliptical galaxy has an elliptical shape, very little gas and dust, and is filled with old red stars that have random orbits in multiple planes. The stars in this type of galaxy group into a ball, rather than as disc-like spiral galaxies.

Which 3 things does a spiral galaxy have that an elliptical does not?

Spiral galaxies are characterized by a central bulge of stars surrounded by a flat disk of stars, gas, and dust, while elliptical galaxies are characterized by a more spherical shape with no disk or spiral structure.

What does elliptical look like

What do spiral and elliptical galaxies have in common?	Elliptical, spiral, and irregular galaxies all contain a combination of stars, interstellar dust, planets, and gases. These three types of galaxies are also formed in the same manner through gravitational forces.
What are the properties of an elliptical galaxy?	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 3 facts about elliptical galaxies?	Follow along for some incredible facts about elliptical galaxies. They Are Largely Featureless. They Can Be the Biggest — or The Smallest. They're Harder to Spot Than Spiral Galaxies. They Might Form After a Collision. Yes, They Have Black Holes Too. They Tend to House Old Stars. They're Primarily Found in Clusters.
What are the 4 distinguishing characteristics of elliptical galaxies?	There are four distinguishing characteristics of the ellipticals: (a) they have much more random star motion than orderly rotational motion (star orbits are aligned in a wide range of angles and have a wide range of eccentricities); (b) they have very little dust and gas left between the stars; (c) this means that they
What is found in an elliptical galaxy?	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.
What are 2 facts about the elliptical galaxy?	Elliptical galaxies have a broader range in size than other types of galaxies. The smallest are dwarf elliptical galaxies, which can be less than 10 percent of the size of the Milky Way. But ellipticals can also stretch to more than a million light-years across, and contain more than ten trillion stars.
What are 3 facts about the elliptical galaxy?	More Than Spirals: Facts About Elliptical Galaxies They Are Largely Featureless. They Can Be the Biggest — or The Smallest. They're Harder to Spot Than Spiral Galaxies. They Might Form After a Collision. Yes, They Have Black Holes Too. They Tend to House Old Stars. They're Primarily Found in Clusters.
What machine looks like an elliptical?	The arc trainer The arc trainer was made to be an improved version of the elliptical, and so in some aspects, it's better than the original machine. It has less impact on your muscles and joints, and it's also more suitable for people with disabilities.
Are ellipticals good for losing weight?	Given that the calorie burn associated with an elliptical is higher than that of some other cardio machines like the stationary bike, it can help you lose body fat in a shorter amount of time. This is especially true if you focus on interval work.
What are the disadvantages of elliptical?	Yes, there are some disadvantages of using an elliptical machine for exercise: Lack of variety: Elliptical machines can become repetitive and boring, leading to a lack of motivation to continue using them. Limited muscle activation: Elliptical machines primarily work the lower body, neglecting upper body muscles. Co.
Does elliptical burn belly fat?	So, are ellipticals good for belly fat and fat reduction overall? The answer is a resounding yes. In fact, elliptical machines facilitate a highly accessible and low-impact activity that can be used to burn calories, get in great cardio sessions, and work all of the major muscle groups.
What is better than an elliptical?	If you are an athletic runner who needs to maintain stamina, the treadmill is better than the elliptical. In the end, it depends on your situation. If you can't decide on one or the other, there's no harm in having both.
Why is the elliptical galaxy apparent shape different?	The disc is usually fairly close to being circular in shape. However, because galaxies are randomly oriented relative to our line of sight, we see most of them tilted, giving them a more or less elliptical shape in the sky, somewhere between face-on and edge-on.
Why do different galaxies have different shapes?	Answer: Galaxy collisions is one reason why there are a wide variety of shapes of galaxies. Another reason, which is the most important driver for galaxy shape variety, is that galaxies evolve as gravity turns gas and dust into stars.
What is the difference between the shape of an elliptical spiral and irregular galaxy?	How are elliptical, irregular, and spiral galaxies different? Elliptical galaxies are shaped like spheres or cucumbers and contain old stars. Spiral galaxies have a central disk surrounded by spiraling arms and possess new stars. Irregular galaxies have no distinct shape and have both old and new stars.
Why do elliptical galaxies look like 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.

• How are elliptical galaxies shaped?
  • Elliptical galaxies don't show any structure, but have a smooth ellipsoidal shape, appearing as a large spherical or elliptical ball of stars. Elliptical galaxies can be classified in terms of how long and thin they appear.
• How many elliptical are there
  • Elliptical galaxies are believed to make up approximately 10–15% of galaxies in the Virgo Supercluster, and they are not the dominant type of galaxy in the 
• Are elliptical galaxies classified by how round or flat they appear?
  • Elliptical Galaxies are designated as type E, with a subclassification based on a measure of the ellipticity of their appearance. In Hubble's classification scheme, an E0 galaxy is very round and an E7 galaxy is very elongated.
• How did you determine elliptical galaxies?
  • In the Hubble classification, the roundest galaxies are labelled E0 and the flattest, E7. In the Hubble Classification scheme, elliptical galaxies are allocated a number from 0 to 7 indicating their ellipticity. Unlike spiral galaxies, elliptical galaxies are not supported by rotation.
• How are elliptical galaxies subdivided?
  • Ellipticals are red in colour, and their spectra indicate that their light comes mostly from old stars, especially evolved red giants. Subclasses of elliptical galaxies are defined by their apparent shape, which is of course not necessarily their three-dimensional shape.
• How are spiral and elliptical galaxies classified?
  • Spiral galaxies have an exponential radial brightness profile, although their central regions ("bulge") also follows a deVaucouleur law. Stars are formed in the spiral arms of spiral galaxies (and can be formed in irregulars), while elliptical galaxies tend to only have old, and consequently low mass, stars.
• What constellation are in the galaxy elliptical
  • Elliptical galaxies are typically found in galaxy clusters. ... elliptical galaxies are largely populated by stars that formed within active spiral galaxies.
• Do elliptical galaxies have more gas and dust?
  • 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.
• Which main type of galaxy is known for having little to no available dust & gas?
  • Unlike spirals, elliptical galaxies usually contain little gas and dust and show very little organization or structure. 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.
• Do elliptical galaxies contain more gas dust and young stars than do spiral galaxies?
  • Elliptical galaxies contain mostly older stars. That means they often aren't as bright as spiral galaxies. They also have very little dust and gas. Elliptical galaxies are the largest and most common galaxies observed.
• Which galaxies have more dust?
  • Type c spiral galaxies have the most gas and dust.
• What galaxies have gas and dust?
  • Spiral galaxies are made up of young stars, gas, and dust. You can see the dust in the dark spots of the spiral arms. The gas and dust are used to make new stars, and these baby stars glow very brightly. Astronomers use these facts to determine that spirals are typically young galaxies.
• Are elliptical galaxies spherical?
  • Elliptical galaxies are characterized by several properties that make them distinct from other classes of galaxy. They are spherical or ovoid masses of stars, starved of star-making gases.
• What determines the shape of an elliptical galaxy?
  • An elliptical galaxy — which has a smooth, ellipsoidal or spherical shape — does not have well-defined features, such as arms or disks. Composed of older stars, they typically contain relatively little interstellar gas and dust. Researchers believe an elliptical galaxy could be a result of colliding galaxies.
• What would be the classification of an elliptical galaxy that is nearly spherical in shape?
  • Scientific definitions for elliptical galaxy The most common type of galaxy, ranging in shape from nearly spherical (classified as E0) to greatly elongated (classified as E7). Elliptical galaxies vary greatly in size and include some of the largest and smallest known galaxies.
