A star is a massive ball of plasma (very hot gas) held together by gravity. It radiates energy because of the nuclear reactions inside it.?A constellation is a group of stars, usually in a recognizable shape or pattern. Together, the stars look like a picture.
- The star that is closest to the Earth is the sun.
- A Star is a gigantic, glowing ball of plasma.
- Stars are first formed as clouds of dust and gas.
- Stars give off a tremendous amount of energy in the form of light and heat.
- Most stars are between 1 billion and 10 billion years old.
- Stars that have really strong gravity grow smaller over time and eventually turn into black holes.
- The hottest stars give off a bluish light while the cooler stars give off a reddish light.
- Stars seem to twinkle because their light travels through the earth’s atmosphere and the turbulence in the atmosphere affects the way stars are seen.
- All the stars that make up the Milky Way Galaxy revolve around the center of the galaxy once every 200 million years or so.
- The oldest star that has been discovered is HE 1523-0901, which is an estimated 13.2 billion years old.
- A constellation is a group of stars that form imaginary outlines.
- Constellations can also represent patterns that depict animals or gods, and sometimes mythological people and creatures.
- There are 88 modern constellations.
- Constellations have changed immensely since their inception.
- Constellations vary in size and shape and some are more popular than others.
- Twelve constellations correlate to the twelve astrological signs:
Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, and Capricorn.
- Constellations are given a point in the celestial coordinate system.
- The word “constellation” comes from a Latin word meaning “set of stars”.
- Although constellations seem close together from far away, many of them are actually very far away from each other and their observer.
- Since stars travel through their own orbits in space, the outlines of constellations can change, too.
- The earliest pieces of evidence for constellations dates back to 3000 BC where inscribed stones and clay tablets were dug up in Mesopotamia (near modern-day Iraq).
- The Babylonians were the first civilization to recognize patterns in the sky and use them in predictions. They even created star catalogues.
- The Greeks adopted the Babylonian system in the 4th century BC.
- Ancient China was a long tradition of observing the sky and studying the systems of constellations.
- Constellations can be divided into two regions – the northern and southern sky; these both have different origins, though.
- Northern hemisphere constellations are deep-rooted in Ancient Greece.
- Southern Hemisphere constellations are more modern inventions and have become substitutes for some ancient constellations.
