What statements describe elliptical galaxies?

They typically contain very little gas and dust. Elliptical galaxies are galaxies where you will find little or no gas and dust. The galaxies that are numerous in number are the elliptical galaxies.

What best describes an elliptical galaxy?

An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the four main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, along with spiral and lenticular galaxies.

What is an elliptical galaxy described as?

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 characteristics of elliptical galaxies?

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.

Is life possible in elliptical galaxy?

Hear this out loudPauseBased 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'.

Frequently Asked Questions

What do elliptical galaxies tend to be?

Hear this out loudPauseUnlike 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.

Which galaxy could have life?

Hear this out loudPauseLarge spiral galaxies are one galaxy type that researchers think may be good for developing life. Our own planet is the only known example of life arising in such a galaxy, but spirals pack relatively high amounts of the heavy elements needed to form rocky planets.

What class are the most circular of the elliptical galaxies?

E0 Classification and characteristics Under this organization, elliptical galaxies are classified by how stretched out they are. Galaxies classified as E0 appear to be almost perfect circles (remember, a circle is an ellipse), while those listed as E7 seem much longer than they are wide.

Which of the following statements describes the orbits of stars within most elliptical galaxies?

Which of the following statements describes the orbits of stars within most elliptical galaxies? They move in random directions with respect to the galaxy itself.

Why do spiral galaxies generally appear bluer than elliptical galaxies?

So the answer to your question is: The reason spiral galaxies are not red is that they keep forming new stars, the most luminous of which are blue. And the reason elliptical galaxies are not blue is that they're unable to form new stars, so only the red ones are left.

Why are spiral galaxies brighter than elliptical galaxies?

Spiral galaxies are bright in appearance due to the active formation of stars. As such, spiral galaxies are considered much younger than elliptical galaxies. Due to the active formation of stars, scientists believe spiral galaxies represent nearly 60% of all galaxies in the universe.

How does the coloring of spiral galaxies compare to the coloring on elliptical galaxies?

We've seen that elliptical galaxies are much redder than spiral galaxies. They also typically have much less neutral hydrogen gas.

Which is redder a spiral galaxy or an elliptical galaxy?

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.

Why are spiral galaxies bluer?

Stars are forming in the spiral arms so there are many more high mass, hot, blue stars. Almost all the stars of the disk are in the arms of the galaxy and their light makes it appear blue.

What describes 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.

Which statements describe elliptical galaxies?

They typically contain very little gas and dust. Elliptical galaxies are galaxies where little or no gas and dust can be seen or found. The elliptical galaxies are the most commonly found galaxies.

How are elliptical galaxies characterized?

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.

How do you identify an elliptical galaxy?

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.

What is the definition of elliptical space?

The definition of an elliptical orbit is an oval-shaped path, like a slightly elongated circle. This is due to the gravitational interactions among the Sun, planets, and other celestial bodies that move in elliptical paths. All planets in our solar system have an elliptical orbit such as the orbit of Mars seen here.

Why are high mass star supernovas rare in elliptical galaxies near us?

Why are high-mass star supernovas rare in elliptical galaxies near us? High-mass stars have all died out in these galaxies. Could the Sun turn into a white dwarf supernova? No, it couldn't, because it doesn't have a binary companion.

Are supernovas more likely to be seen in spiral galaxies or elliptical galaxies?

In spirals, the rates of all supernova types are correlated with galaxy color: the bluer the galaxy—and, by inference, the higher the star formation rate within the last billion years—the higher the supernova rate. Elliptical galaxies produce only SNe Ia, at a lower rate than spirals.

What is the most likely reason for the formation of extremely large elliptical galaxies?

Current thinking amongst astronomers is that most elliptical galaxies formed from the collisions and subsequent mergers of spiral galaxies.

FAQ

What type of stars are 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.
Why are high mass stars rare?
One reason for this is that massive stars are relatively rare — lower-mass stars are more common than higher-mass stars, Schneider said. Another reason is that massive stars have much shorter lives than lower-mass stars do, he added — because massive stars burn hot, they go through fuel quickly and die young.
What is the characteristic of a 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. An elliptical galaxy is one that was created when other galaxies collided.
Which of the following best describes an elliptical galaxy?
An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image.
What best describe elliptical galaxies?
Four classes are used to classify galaxies: spiral; barred spiral; elliptical and irregular. 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 elliptical galaxies classified by?
Under this organization, elliptical galaxies are classified by how stretched out they are. Galaxies classified as E0 appear to be almost perfect circles (remember, a circle is an ellipse), while those listed as E7 seem much longer than they are wide.

Toomre & Toomre (1972) suggested that elliptical galaxies can form from major mergers of massive disc galaxies.
What is the hypothesis of the galaxy formation?
Galaxy formation is hypothesized to occur from structure formation theories, as a result of tiny quantum fluctuations in the aftermath of the Big Bang.
What is one likely way for elliptical galaxies to form?
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.

Which phrase accurately describes an elliptical galaxy?

Why is a dense cloud more likely to produce an elliptical? Hear this out loudPauseWhy is a dense cloud more likely to produce an elliptical galaxy than a spiral galaxy? The higher gas density forms stars more efficiently, so all the gas is converted into stars before a disk can form.
What is the main theory on how elliptical galaxies are made? Hear this out loudPauseElliptical 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.
Are elliptical galaxies more dense? Hear this out loudPauseThe results are pretty clear: in high-density environments, early-type (elliptical) galaxies grow more common. in low-density environments, late-type (spiral) galaxies are more common.
What is the difference between spiral and elliptical 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.
What is the major difference between an elliptical galaxy and a spiral galaxy quizlet? The major difference between spiral and elliptical galaxies is that elliptical galaxies lack a significant disk component, although both types have the halo component.
What is the difference between elliptical and irregular galaxies? As their name suggests, elliptical galaxies are round or oval, with stars distributed fairly uniformly throughout. They have a bulge and halo, like spiral galaxies, but don't have the flat disk of stars. The stars in ellipticals tend to be older. Irregular galaxies have no identifiable shape or structure to them.
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.
How do elliptical galaxies get so large? Giant elliptical galaxies are generally thought to be the result of galaxy mergers. Ordinary elliptical galaxies may also form in this manner, or may have formed from the gravitational collapse of an interstellar gas cloud.
What do elliptical galaxies evolve into? Originally, Edwin Hubble hypothesized that elliptical galaxies evolved into spiral galaxies, which was later discovered to be false, although the accretion of gas and smaller galaxies may build a disk around a pre-existing ellipsoidal structure.
When galaxies merge to form larger galaxies? Mergers. If colliding galaxies don't have enough momentum to move past each other, they can merge to form a single larger galaxy. A merged galaxy can look very different from the two that created it. For example, if a spiral and elliptical merge, the result could be an irregular galaxy.
What do elliptical galaxies tend to be larger and have? A likely outcome of the collision of two spiral galaxies of similar size is an elliptical galaxy. In general, elliptical galaxies grow to larger sizes than their spiral counterparts and have lower gas content. With the gas-starved blunted SFR the ellipticals are primarily composed of older, less massive stars.
How do galaxies get bigger? Galaxies, like the pennies, don't expand, rather it's the space between the pennies that's expanding. Objects held together by gravity or other forces, including individual galaxies, individual stars and planets, and even ourselves, are not expanding.
Which phrase accurately describes an elliptical galaxy Which phrases accurately describe an elliptical galaxy? a) may be spiral-shaped. b) has no recognizable shape. c) has no new stars being formed.
High density clouds produce elliptical galaxies why If cloud had little or no angular momentum, then its gas might not collapse into a disk at all, leading to formation of elliptical galaxy. If cloud has higher 
What causes the dark band seen in galaxy H? Brighter regions indicate denser concentrations of stars. Darker regions across the Galactic Plane correspond to dense clouds of interstellar gas and dust that absorb starlight.
Why are elliptical galaxies 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. The existing stars inside an elliptical galaxy tend to be older, giving off more red light than younger stars.
  • Does elliptical galaxy have dark matter?
    • In conclusion, elliptical galaxies could have dark matter halos similar in mass and extent to those in spiral galaxies (Danziger, 1997), but the evidence is not so clear and it cannot even be completely rejected that they possess no dark halo at all.
  • Why does the disk of a spiral galaxy appear dark when viewed edge on?
    • In a spiral galaxy, dust is concentrated in the plane of the disk. When seen edge on, light from the stars must reach us by traveling through the disk, and the dust in the plane of the galaxy absorbs the starlight within the galaxy, making it appear darker.
  • What is the dark band in the Milky Way?
    • In astronomy, the Great Rift (sometimes called the Dark Rift or less commonly the Dark River) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure (extinguish) the center and most radial sectors of the Milky Way galaxy from Earth's perspective.
  • What would the night sky look like on a planet in the galactic center?
    • If you lived in the center of the Milky Way, you would look up at a sky thick with stars, up to 1 million times denser than we're used to seeing. The closest star to our sun is about four light-years away; in the center of the galaxy, stars are only 0.4–0.04 light-years apart.
  • What would the night sky look like outside the galaxy?
    • You would not see any stars, as all the stars we see on our sky are from our galaxy. You might be able to see some Active Galactic Nuclea, which are far away galaxies that look like stars (point sources), and are extremely luminous, so we are able to see them even though they are really far away.
  • What does the galaxy look like at night?
    • From Earth at certain times of year, the Milky Way is visible overhead in the night sky from dark locations (you can't see the Milky Way from under bright city lights). It looks like a giant swath of milky haze in the sky, which is where it gets the name.
  • Would life still be possible in elliptical galaxy?
    • Indeed, each giant elliptical that is at least twice as big as the Milky Way and has a tenth of its supernova rate could potentially host 10,000 times as many habitable (Earth-like) planets.
  • How many stars are in a giant elliptical galaxy?
    • They contain tens of millions of stars. The largest ones can contain over a trillion (1,000,000,000,000)! Some ellipticals can be very dim and some very bright.
  • Do elliptical galaxies have a lot of stars?
    • 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.
  • Are giant elliptical galaxies rare?
    • The largest and rarest of these, called giant ellipticals, are about 300,000 light-years across. Astronomers theorize that these are formed by the mergers of smaller galaxies. Much more common are dwarf ellipticals, which are only a few thousand light-years wide.
  • How do giant ellipticals get so big?
    • Giant elliptical galaxies are generally thought to be the result of galaxy mergers. Ordinary elliptical galaxies may also form in this manner, or may have formed from the gravitational collapse of an interstellar gas cloud.
  • How big can giant elliptical galaxies be?
    • 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 do elliptical galaxies look like?
    • Four classes are used to classify galaxies: spiral; barred spiral; elliptical and irregular. Elliptical galaxies have a smooth ellipsoidal or spherical appearance, and they have far less structure than spiral galaxies do.
  • Does elliptical galaxies look like a egg in its shape?
    • Lenticular galaxies also have a clearly-defined disk, though they have more in common with elliptical galaxies than spiral galaxies do. Elliptical galaxies earn their name by having a three-dimensional ellipsoid shape, i.e. they look egg-like from any direction.
  • What color is an elliptical galaxy?
    • Yellow-red Elliptical galaxies are ellipsoidal in shape, contain no spiral arms, contain little interstellar gas or dust, and are found mostly in rich clusters of galaxies. Elliptical galaxies appear typically yellow-red, as opposed to spirals which have spiral arms that appear quite blue.
  • What does elliptical look like?
    • With little to no impact. Another great reason the elliptical works so well is because you can change your movement pattern from cycling to stepping to cross country skiing to climbing. You have the
