Amazing Space Glossary of Astronomy Terms - Part 1 of 4 (NASA) Asterism: A pattern formed by stars not recognized as one of the official 88 constellations. Examples include the Summer Triangle, the Big Dipper, and the Winter Circle. Barred Spiral Galaxy: A type of spiral galaxy having a linear extension, or 'bar,' made of stars and interstellar matter, passing through its center. Blue Star: A very hot star with a short lifetime. Blue stars exist for a few million years. Sirius (Alpha Canis Majoris) is an example of a blue star. Bulge: A rounded structure in the centers of some galaxies, composed primarily of old stars, and having some gas and dust. The bulge of the Milky Way is about 10,000 light- years across. Colliding Galaxies: When two or more galaxies are close enough, their gravity begins to attract each one toward the other. The attraction increases as the galaxies travel even closer together. These galaxies can collide and possibly merge to form an elliptical galaxy. Compare/Contrast Chart or T-chart: A graphic organizer used to compare two objects or ideas. The objects are listed as headings at the top of two columns. The characteristics being compared are then listed under each heading. The chart’s top, horizontal line and its center vertical line trace out the shape of a 'T.' Constellations: “Pictures” in the sky that ancient astronomers perceived by imagining lines or relations between stars that appear grouped. Often, mythological heroes or creatures were the subjects of the pictures. Creating the constellations in the sky not only provided stories for amusement, but also helped people remember the positions of the stars. Knowing the positions of the stars helped farmers keep track of the seasons and travelers keep track of where they were. Modern astronomers define 88 constellations, which are spread across the entire sky. Part 1 Part 2 Part 3 Part 4 | ||
