Impact Craters

When a Metorite collides with Earth it can form an impact crater – a bowl – shaped hollow in the Earth’s surface. Space rocks have produced in this way throughout Earth’s life, especially when the planet was young, about 4 billion years ago.

Space rocks do not have to hit Earth to have a devastating effect. On june 30, 1908, there was an explosion 3.5 miles up in Earth’s atmosphere, above the unpopulated Tunguska River region of Siberia. It was caused by the disintegration of a small piece of comet or asteroid. The blast uprooted trees in a 12-mile area and was heard up to 600 miles away.

How Far are the Stars
Until 1838, Astronomers had little idea of the true size of the Universe. But in that year, Friedrich Bessel used a technique called the parallax method to make the first successful measurement of the distance to a star. Modern astronomers have many different ways of figuring out how far away an object is, but they all depend ultimately on the parallax method. As the Earth orbits the S...
Exploring the Moon
People have dreamed of exploring the Moon for hundreds of years. The United States and Russia made the dream a reality in the middle of the 20th century. In 1959, Luna 1- the first spacecraft to leave the Earth’s gravity – was launched toward the Moon. A decade of intense space activity followed as Russian and American probes, robots, and crewed craft were sent to investigate and land on the l...

The Birth of a Solar System
Most astronomers believe that all the members of the solar system, from the giant Sun to the smallest asteroid, were born out of a vast, spinning cloud of gas and dust – the solar nebula. The process began 5 billion years ago with the formation of the Sun. The planets and other objects formed from unused material. When the solar system was nearly complete, 500 million years later, just 0....

Polar Star has sufficient body ability to ingest the elevated-controlled ice slamming normal to her operations. The shell plating and cohorted interior uphold structure are created from steel that has particularly great flat-temperature quality. The part of the body outline to slam ice is 1-3/4 creeps (45 mm) thick in the bow and stern areas, and 1-1/4 crawls (32 mm) thick amidships. The frame...
Lunar Eclipses Explained
A eclipse occurs when the Moon passes straight at the rear of the Earth into its umbra (shadow). This will happen only once the sun's rays, Earth, and Celestial satellite are aligned specifically, or extremely closely thus, using the World in the middle. Therefore, the eclipse can only occur the night time of your full-of-the-moon. The sort and also period of a great eclipse depend upon the Mo...
Debris That Hit Space Shuttles
