a giant elliptical can contain how many stars
arms, a bulge at its center, and a halo. Spiral galaxies have a variety of shapes and are. classified according to the size of the bulge and the tightness and appearance of the. arms. The spiral arms, which wrap around the bulge, contain numerous young blue. stars and lots of gas and dust. Stars in the bulge tend to be older and redder. What size is a Giant Elliptical Galaxy? _____ How many stars are in a Giant Elliptical Galaxy? _____ Step 11: Click on the button. Step 12: Select “Irregular Slide” for the next activity. Go ahead and start the game they have for introducing you to irregular galaxies. Step 13: Select the button, and take a look at some Irregular Most common type, most of these are dwarf galaxies (too small and too dim to be easily seen). Shaped like large, 3-dimensional ellipses (football shaped). Giant elliptical galaxies can be over 9 million light-years across and contain trillions of stars.. Dwarf elliptical galaxies- only about 3,000 light-years across and contain fewer than a million stars. Most contain little gas and dust and cannot make new stars. Irregular galaxies can take many different shapes and contain 100 million to 10 billion stars, Less common than elliptical or spiral. a. Larger than Dwarf ellipticals but smaller than spiral galaxies. a galaxy that does not have a regular shape, typically smaller than other types or galaxies, generally have bright, young stars and lots of gas and dust to form new stars. Name: _______________________________________________________________. Background: How Are Galaxies Classified? What Do They Look Like? Edwin Hubble classified galaxies into four major types: spiral, barred spiral, elliptical, and irregular. arms. The spiral arms, which wrap around the bulge, contain numerous young blue stars and lots of gas and dust. Stars in the bulge tend to be older and redder. Yellow stars like our Sun are found throughout the disk of a spiral galaxy. These galaxies rotate somewhat like a hurricane or a whirlpool. Here are directions to getting started on the Galaxies Galore Activity! Step 1: Go to the URL http://amazing-space.stsci.edu/resources/explorations/galaxies-galore/index.html Step 2: Select “Galaxies Galore” Step 3: Select “Spiral Shapes” Step 4: Go ahead and play the game. See if you can match the spiral galaxy Larger galaxies can have more: Andromeda Galaxy, for instance, may have as many as 500. Some giant elliptical galaxies (particularly those at the centers of galaxy clusters) such as M87, have as many as 13,000 globular clusters. smooth, ball-shaped appearance. Ellipticals contain old stars, and possess little gas or dust. They are classified by the shape of the ball, which can range from round to oval (baseball-shaped to football-shaped). The smallest elliptical galaxies (called dwarf ellipticals) are probably the most common type of galaxy in the nearby universe. In contrast to spirals, the stars in ellipticals do not revolve around the center in an Globular cluster. The Messier 80 globular cluster in the constellation Scorpius is located about 30,000 light-years from the Sun and contains hundreds of thousands of stars. A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers. The name of this category of star cluster is derived from the Latin globulus—a small sphere. A globular cluster is sometimes known more simply as a globular. Globular clusters are found in the halo of a galaxy and contain considerably more ... Thus the age of a single population cluster can be measured by looking for the stars that are just beginning to enter the giant star stage. This forms a knee in the HR diagram, bending to the upper right from the main-sequence line.
Giant elliptical galaxies contains trillions of stars.
