- Among the most brilliant and most rare objects in the night sky, a comet is a small, frozen mass of dust and gas revolving around the sun.. These soaring beacons with their beautiful tails come from the outer realms of the Solar System.
- A collection of stars, gas, and dust bound together by gravity. The smallest galaxies may contain only a few hundred thousand stars, while the largest galaxies have thousands of billions of stars. The Milky Way galaxy contains our solar system.
- Our Universe is so vast that we can’t possibly categorize it all, explore the uncategorized!
- A nebula is a cloud of gas and dust in space. Some nebulas are regions where new stars are being formed, while others are the remains of dead or dying stars. Nebulas come in many different shapes and sizes. There are four main types of nebulas: Planetary nebulas, Reflection nebulas, Emission nebulas, and Absorption nebulas. The word nebula comes from the Latin word for cloud.
- The sky, also known as the celestial dome, commonly refers to everything that lies a certain distance above the surface of Earth, including the atmosphere and the rest of outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling.
- A solar system consists of a star and all the objects orbiting it as well as all the material in that system. Our Solar System includes the Sun together with the eight planets and their moons as well as all other celestial bodies that orbit the sun.
- From rockets to observatory’s, explore the technology that powers space exploration.
- A star is a huge sphere of very hot, glowing gas. Stars produce their own light and energy by a process called nuclear fusion. Fusion happens when lighter elements are forced to become heavier elements. When this happens, a tremendous amount of energy is created causing the star to heat up and shine. Stars come in a variety of sizes and colors. Our Sun is an average sized yellowish star. Stars which are smaller than our Sun are reddish and larger stars are blue.
- These are just APOD’s I have yet to assign a category to, this will not be included in the final design.
- Explore APOD’s as moving pictures!
