1 WORDS IN CONTEXT DAY 1 (Page 1 of 4) galaxy A galaxy is a collection of stars, gas, and dust. We live in the Milky Way galaxy. One galaxy may contain billions of stars. solar system A solar system revolves around one or two stars, not billions of stars, as in a galaxy. Our solar system includes the Sun and all the bodies within its gravitational pull. There are eight known planets in our solar system. supernova A supernova is an exploding star. A supernova is a star, not a planet. A supernova is a relatively old star.

2 WORDS IN CONTEXT DAY 1 (Page 2 of 4) telescope A telescope magnifies whatever it is pointed at, similar to binoculars but much stronger. A telescope makes distant objects appear closer and larger. It was thrilling to see Saturn through a telescope. light-year A light-year is the distance that light travels in one year, which is nearly six trillion miles. A light-year is the unit of measure used to calculate the distance from Earth to stars in space. A light-year is not a unit of time. black hole A black hole is likely formed by the collapse of a giant star. A black hole is not really a hole but rather a region of space from which no matter or radiation can escape. If the Sun were compressed to a tiny size, it would become a black hole because the greater the mass in a space, the stronger its gravitational pull.

3 WORDS IN CONTEXT DAY 1 (Page 3 of 4) star A star gives off light, but a planet does not. The star closest to Earth is the Sun. A star in the night sky seems to twinkle, but it has a steady light. astronomer An astronomer is a scientist who studies planets, stars, galaxies, and other objects in space. You would expect an astronomer to use a telescope. She wants to be an astronomer someday, so she is taking many science classes in college. orbit (verb) To orbit is to revolve around another object along a path. Mercury, Venus, Earth, and several other planets orbit the Sun. Jupiter's moons orbit, or travel around, Jupiter.

4 WORDS IN CONTEXT DAY 1 (Page 4 of 4) cluster A cluster is a group of similar objects, such as flowers or rocks. A group of stars is often referred to as a cluster. A star cluster may look like one fuzzy star from far away, but it's actually thousands of stars in a group. deep space Deep space is located beyond the Sun and all the celestial bodies that orbit it. When you look at constellations in the night sky, you're looking into deep space. Deep space, or outer space, contains stars, planets, and moons. big bang theory According to the big bang theory, the universe began about 15 billion years ago. The "bang" in the big bang theory is a huge explosion believed by many to have created time, space, matter, and energy. According to the big bang theory, the universe has continued to expand outward ever since the original explosion.
