Space Shadows

Have you ever held your hand up In front of a bright light to make shadow pictures on the wall The Sun and Moon can cast shadows on the Earth just like the light and your hand cast shadow pictures on the wall. Sometimes the Moon passes between the Earth and the Sun in just the right place to cast a shadow on the Earth. The sky darkens. The air becomes cooler. It seems like the middle of the night. This is called a solar eclipse. Write solar eclipse on the picture which best shows one. The Moon...

Sunsational Puzzle

If we could travel from the Sun's core, or center, to the surface we would be at the photosphere, which is the surface part of the Sun seen from Earth. Flashes of light seen by scientists on the surface of the Sun are called flares, and dark patches are called sunspots. Sometimes eruptions of gas. called prominences, can also be seen during a solar eclipse. Just above the Sun's surface is a layer of bright gases called the chromosphere. The corona, the region beyond the chromosphere, consists...

Moons Faces

As the Moon orbits the Earth, we often see different amounts of the Moon's lighted part. Sometimes it looks like a circle, half-circle, or thin curved sliver. These different shapes are the Moon's phases. Cut out the Moon's phases (as seen from Earth) at the bottom of this page. Glue them next to the Moon phase as seen from space. Label the pictures using the words in the Word Bank. Use a science book to help you.

Cancer the Crab

Cancer (KAN-sir) is one of the faintest constellations of the zodiac. If it weren't for its membership in the zodiac, few people would have heard of it. It has no bright stars. Cancer is midway between the major constellations Leo and Gemini. It is in the early evening sky from February through May. In Greek mythology. Cancer was a crab that was sent to bite Hercules.

Earths Nearest Neighbor

Although the Moon looks round, it is slightly egg-shaped and is much smaller than Earth. It is a little more than one-fourth the size of Earth. The Moon does not have an atmosphere to protect it, so it can get as cold as -200 F at night or as hot as the boiling point of water during the dayl While planets in the solar system orbit the Sun, moons travel around the planets. Our Moon orbits Earth 27.3 days, nearly a month. Look at the chart below to find out how many moons each of the planets in...

Star Search

On a clear dark night, you can look up in the sky and see about 2,000 stars without the help of a telescope. But unless you know which stars form constellations, all you will be seeing are stars. Carefully poke holes in the Constellation Patterns sheet on page 239, using a sharp pencil. Then, tonight, when it is dark, hold a flashlight behind the paper to make the constellations appear. Below are star charts to further help you recognize the constellations. To use the charts, turn them until...

Fascinating Facts About Mercury

Mercury is the planet nearest to the Sun. It is the second smallest planet in our solar system. No planet experiences more radical temperature changes than Mercury. The temperature can rise to 800 F during the day and drop to -275 F at night. Mercury is a world without an atmosphere. It has no air or life of any kind. It is also covered with thousands of ancient craters. Because it is so near the Sun, Mercury can actually have two sunrises in a single day A solar day on Mercury, from sunrise to...

Leaning Into Summer

Why isn't it summer all year long The seasons change because the Earth is tilted like the Leaning Tower of Pisa. As the Earth orbits the Sun, It stays tilting in the same direction in space. Let's look at the seasons in the Northern Hemisphere. When the North Pole is tilting toward the Sun, the days become warmer and longer. It is summer. Six months later, the North Pole tilts away from the Sun. The days become cooler and shorter. It is winter. Directions Label the Northern Hemisphere's seasons...

Fast Fall

Do heavy objects fall faster than light objects Background Gravity is a force, or type of energy, that pulls all objects toward Earth.

It Is at its best spot for viewing in the early summer, when It is in the southern sky. Libra is a set of balance scales that work by balancing two pans hanging from a lever, like the scales of justice seen on court buildings. The Sumerians may have originally called these stars scales because the Sun was In front of these stars on the first day of autumn, when...

Beyond Our Solar System

Astronomers know that much lies beyond our solar system. In fact, in the drawing on this page our solar system is just a tiny speck in a larger group of objects in space. This larger group is called the Milky Way galaxy. The Milky Way is made up of all the stars you can see in the night sky and many more beyond those. II also contains large clouds made of gas and dust. But that's not all Beyond our Milky Way. astronomers have seen millions of other galaxies. Each of these has billions of stars....
