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.

Saturn Explained: Inside and Out
Saturn is the sixth planet from the Sun and the second vastest planet in the Earth's planetary group, following Jupiter. Named following the Roman god Saturn, its galactic image (♄) speaks for the god's sickle. Saturn is a gas goliath with a normal span something like nine times that of Earth.[12][13] While a single-eighth the middle thickness of Earth, with its more substantial volume Saturn ...

Radio Astronomy
Radio waves are the same type of waves as light. They have less energy than visible light and so have a longer wavelength, but they travel at the same speed as light. At night our eyes and optical telescopes sees light from stars. But normal stars only produce radio waves very weakly.

Satellites Orbiting Earth
In the connection of spaceflight, a satellite is an item which has been put into space by human endeavour. Such protests are now and again called simulated satellites to recognize them from instinctive satellites for example the Moon.

Moon World Map
The Moon (Latin: luna) is the sole characteristic satellite of the Earth, and the fifth most imposing satellite in the Earth's planetary group. It's the greatest characteristic satellite of a planet in the Earth's planetary group with respect to the span of its primary, having 27% the width and 60% the thickness of Earth, bringing about 1⁄81 its mass. The Moon is the second densest satellite f...

Measuring the Stars
As we cannot yet travel outside the solar system, we have to learn as much as we can about the stars by studying them at a distance. Astronomers can tell the brightness, color, and temperature of a star by analyzing the light it gives out. By splitting starlight into its constituent colors, they can find out what the stars are made of and how fast they are moving. Stars are so far awa...

According to Quantum mechanics, electrons bound to an atom can only have particular values of energy; they are unique to that element. Absorption or emission of a photon of light by the atom occurs when the energy of that photon matches the difference between two of these energy levels. The gravitational pull of any object gets weaker the further you move from the object. Thus, the Moon p...

Star Map - Northern Hemisphere December to May
In winter, constellations and stars are the main attractions because the milky way is faint. These include the brightest constellation, Orion, and the brightest star. Most of the visible stars are in our own local arm of the galaxy, which also contains several star nurseries that can be seen in close – up such as the Orion Nebula.

Understanding Auroras
The gathering storm is formed when the solar wind’s magnetic field is pointing in the opposite direction to that of the Earth, it sets up a chain of events that leads to a substorm and produces a Spectacular Aurora. The Earth’s magnetic shield, or magnetosphere, protects the planet from the solar wind, which usually just passes around the earth.

A Brief History of the Solar System
The process of existence or initiative of life in the Solar System looks very interesting. Life in the solar system is a monomeric nucleotide, pretty much just a simple molecular compound made out of a normal, every-day inorganic material. Life started in the Earth once the things inside it are cooled down a bit. Basically life in the Earth is a replicator, the way it just happened or formed. Life...
