They dont rotate very much and look like the bulge of a spiral galaxy. Spiral elliptical and irregular.

Most galaxies are spiral milky way elliptical lenticular and irregular shape.
. With information about the speeds it is possible to calculate the mass of an elliptical galaxy. Spiral Galaxies have a bulge in the center with a spherical halo around it and a thin disk that rotates with spiral arms. Which statement best describes a galaxy.
A low mass galaxy that only has young stars but is making a lot of them. And some galaxies are neither spiral nor elliptical they are irregular. A planet has less mass than a galaxy and more mass than the star it orbits.
The table below shows the distances of three stars from the sun. Cause galaxies to take different shapes. In 1926 Edwin Hubble devised a system to classify galaxies.
As it turns out the biggest and most luminous galaxies come in one of two basic shapes. Classification and characteristics. However the mass of the Sun is completely trivial compared to the mass of the Galaxy.
They contain very little dust or gas and the stars contained here are. The stars and gas in almost all galaxies move much quicker than expected from the luminosity of the galaxies. The mass of the Earth is about 50 times the mass.
Many smaller galaxies in contrast have an irregular shape. Thus for all practical purposes the result about 100 billion times the mass of the Sun is the mass of the Milky Way. Students were asked to make a model of the three stars and to include the sun and Earth in the model.
How do gravity and dark matter shape the galaxies and affect their environment. Elliptical galaxies have almost no gas or dust between starts. The mass of the Galaxy can be determined by measuring the orbital velocities of stars and interstellar matter.
Our Milky Way is a spiral as is the rather close-by Andromeda Galaxy. Both are formed by gravitational forces. Shaped as an ellipse or sphere.
Masses are small and the objects are far apart. Known as the Hubble sequence or the Hubble tuning-fork it organizes galaxies based on their shape. Elliptical galaxies are generally smooth and oval.
As much as 95 of this mass consists of dark matter that emits no electromagnetic radiation and can be detected only because of the gravitational force it exerts on visible stars and interstellar matter. The appropriate answer is C. The total mass of the Galaxy is about 2 10 12 M Sun.
Most galaxies are spiral milky way elliptical lenticular and irregular shape. Transition galaxies combine the features of spiral and elliptical galaxies. Interestingly enough the most and least massive galaxies are ellipticals.
A galaxy with a mix of old and new stars is making some new stars. Of all classes of galaxies elliptical galaxies show the widest range of properties between the dwarf examples and the giant systems with mass ranging from 10 6 to 10 13 solar masses sizes from 1 kpc to 150 kpc in diameter and luminosities 10 6 to 10 12 solar luminosities. Spirals are the most common large-mass galaxies Lenticular galaxyhas a disk like a spiral galaxy but much less dusty gas intermediate between spiral and elliptical Spiral galaxies are often found in groups of galaxies up to a few dozen galaxies.
Elliptical galaxies vary more in shape than spiral galaxies. Perhaps 70 percent of all galaxies are ellipticals but the vast majority are dwarfs. Spiral galaxies are the most common type in the universe.
Has a halo bulge and a disk -elliptical galaxies. The elliptical galaxys mass k velocity dispersion 2 the distance the stars are from the galaxy centerG where k is a factor that depends on the shape of the galaxy and the angle the galaxy is from Earth. Which of the following best describes the black hole status within the Milky Way.
An irregular galaxy is a galaxy that does not have a distinct regular shape unlike a spiral or an elliptical galaxy. Stellar-mass black holes have a solar mass of five to several tens of times the mass of the sun so. A student is taking a multiple choice exam.
Elliptical galaxies have no disk and no arms and very little gas and dust. Plugging numbers into Keplers formula we can calculate the sum of the masses of the Galaxy and the Sun. Which statement best describes how most galaxies generally move.
Which diagram best approximates the shape of the path of Earth as it travels around the sun. Earth is a part of this galaxy. Spiral galaxies range from intermediate to large galaxies with masses in the range of 10 9 to 10 12 solar masses diameters 6 kpc to 100 kpc and luminosities 10 8 to 10 11 solar luminosities.
The central bright region at the core of a galaxy is called the galactic bulge. Which of the following is s major difference between elliptical galaxies and spiral galaxies. On average irregular galaxies have less mass than spirals.
A large weirdly-shaped galaxy that has old stars but is also making lots of new ones. Spirals are large rotating disks of stars and nebulae surrounded by a shell of dark matter. Either they are flatter and have spiral arms like our own Galaxy or they appear to be elliptical blimp- or cigar-shaped.
The first shape to be known was spiral because milky way is a spiral galaxy. More older stars than newer. The first picture shows an elliptical galaxy.
Table 1 summarizes the range of masses and other properties of the various types of galaxies. These galaxies can be round nearly spherical or flattened disks. Which of these best explains why people on Earth cannot see the entire shape of the Milky Way.
Elliptical galaxies are generally smooth and oval. Describe the main distinguishing features of spiral elliptical and irregular galaxies. Spiral galaxies look like pinwheel.
They chose to use a scale of 1 meter.
