THE MARS ( "King of the Sacred Grove" ) Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past. It is the next planet beyond Earth. Mars is more than 142 million miles from the Sun. The planet is about half the size of Earth. A day on Mars is 24.6 hours. A year on Mars is 687 Earth days. Mars is known as the Red Planet. It is red because the soil looks like rusty iron. Mars has two small moons. Their names are Phobos (FOE-bohs) and Deimos (DEE-mohs). Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather. It has a very thin atmosphere made of carbon dioxide, nitrogen, and argon. There are signs of ancient floods on Mars, but now water mostly exists in icy dirt and thin clouds. On some Martian hillsides, there is evidence of liquid salty water in the ground.

MIND BLOWING FACTS ABOUT STARS The stars have throughout history been fascinating objects of study. From the ancient Greeks, to the modern day astronomers who continually search the stars for other planets and galaxies. The universe is constantly expanding, and changing, thus every time an astronomer looks into his telescope he may see something there that wasn’t there the day before! In a place full of so much wonder and so many unknowns, it’s no wonder there are tons of facts about stars. Here are 46 fascinating facts about stars: 1. At the most conservative estimate, there are at least 10 billion trillion stars in the universe. 2. Red stars are relatively small and cool, while the hottest burn blue-white. 3. Medieval alchemists studied the North Star, believing it held the secret to perpetual motion. 4. Stars are formed from dense knots contained in large clouds of dust and gas called nebulae. 5. There is enough matter in the Orion Nebula to produce over 10,000 stars. 6. The ancient...

THE SUN (Heart Of Our Solar System) The Sun is a star a vast sphere of luminous gas . Its light is a by-product of gas-fueled nuclear reactions in its core. It shines steadily now, but in about five billion years it will swell up before dying as a cold, dark cinder in space.  The   Sun   is a star which is located at the center of our solar system . It is a yellow dwarf star that gives off different types of   energy   such as   infra-red   energy (heat),   ultraviolet light ,   radio   waves and light. It also gives off a stream of   particles , which reaches Earth as " solar wind " . The source of all this energy is   nuclear fusion . Nuclear fusion is the reaction in the star which turns   hydrogen   into   helium   and makes huge amounts of energy. I NTRODUCTION The Sun is a star like many others in our   Milky Way   galaxy . The Sun is a type of star called a   G-type main-sequence star...
