Astronomy Reader Bundle includes twelve (12) books
In What is Astronomy?, young readers learn Astronomy is the study of stars and other objects in space. Ancient peoples studied the sky, named stars and groups of stars, and created calendars. Astronomers use telescopes, including space telescopes, and other tools to study faraway objects.
A black hole is an object in space with such massive gravity that no light can escape or bounce off it—it can’t be observed directly. Nearby materials and objects are pulled into it. A black hole can result from a supernova. Most galaxies have a black hole at the center.
In Constellations, young readers learn a constellation is a group of stars that forms a shape and has been given a name. Different constellations can be seen from different locations on Earth. Some can be used for navigation. Several constellations are illustrated.
In Earth in Space, young readers learn Earth is a planet - an object in space that has its own gravity, is spherical, and moves around a sun. The combination of Earth’s tilt on its axis and its orbit around the Sun creates the seasons. Rotation on the axis causes day and night.
Exploding Stars: A star is an object in space that makes its own light & heat energy. Stars are born in clouds of gas and dust and die when they run out of fuel. A big star ends its life in an explosion called a supernova that scatters atoms throughout the universe.
Galaxies: A galaxy is a huge group of stars, planets, gas, comets, asteroids, and other objects in space. Our Sun and Earth are part of the Milky Way Galaxy. Telescopes are used to study galaxies. Spiral, elliptical, and irregular galaxies are described.
In Nebulae, young readers learn a nebula is a huge cloud of gas and dust that swirls to make beautiful cosmic art. Some nebulae are areas in space where new stars are formed. Some nebulae are formed when a dying star explodes and turns into gas and dust.
In Our Solar System, young readers learn a solar system contains a star and the planets and other objects that orbit it. Our solar system has 8 planets (including Earth) moons, asteroids, and comets organized into an inner and outer solar system with the Asteroid Belt in between.
In Planets, young readers learn a planet is an object in space that orbits a star, is spherical, and is big enough to have its own gravity. Earth is one of 8 planets that orbit the Sun. There are two different types of planets. Terrestrial planets are Earth-like, and Jovian planets are Jupiter-like.
A star is an object in space that emits heat and light energy when hydrogen atoms combine to make helium. Stars are different sizes and give out different amounts of light. Several significant stars are described.
In The Moon, young readers learn the Moon is spherical, much smaller than Earth, made of rocks and minerals, has little air, has ice but no liquid water, and has gravity. It reflects light from the Sun and looks different from day to day. The surface has craters and lava flows.
The Sun is a star, an object in space that makes its own light and heat energy when helium and hydrogen atoms undergo nuclear reactions. The Sun’s energy makes life possible on Earth by providing warmth and light for plants to use to make food.
