A planet is a heavenly figure circling a star or stellar remainder that is monstrous enough to be adjusted by its particular gravity, is not colossal enough to create thermonuclear combination, and has cleared its neighboring area of planetesimals. The term planet is antiquated, with ties to history, science, mythology, and religion. The planets were basically viewed by a considerable number of early societies as heavenly, or as emissaries of divinities.

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...

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...

Deflecting Asteroids
Every object exerts a gravitational pull, including a single spacecraft. Merely by hovering above the asteroid. It could pull the rock off course. The approach could even be tried with the Dawn spacecraft, scheduled to finish its tasks in the asteroid belt by 2015. However, such a strategy would be very slow, requiring years or even decades to alter the path of the asteroid.

Star Map - Southern Hemisphere September to February
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...

Mars World Map
In 1659 Dutch astronomer Christian Huygens, using an early telescope, drew the first sketch of a surface feature on Mars, a dark patch know today as Syrtis Major. More than three centuries later the mars global Surveyor is charting the entire planet. Data beamed from the orbiting surveyor have rendered a detailed and true-color map of this seemingly most Earthlike of planets.

Phases of Venus
Parallel to the Venus Express Mission, ESA has initiated an observing campaign that incorporates a number of professional and amateur observers. Since the cameras onboard Venus Express have only a small field of view, ground based observations can provide important context information on Venus’s dense atmosphere as a whole.

Boltzmann's Theory
The work of the Austrian physical Ludwig Boltzmann suggested an answer to the question: why does time seem to go only in one direction ? Boltzmann suggested that the amount of disorder, or entropy, in the universe increases over time.

Saturn and its Moons
Saturn is the sixth planet from the Sun and the second most expansive 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 mammoth with a middle range something like nine times that of Earth. While one and only one-eighth the mean thickness of Earth, with its more impressive volume Sa...

Exploring the Planets
A planetary spacecraft has basic instruction programmed into its onboard computers at launch. However, most of the details are sent by controllers on Earth at a later stage, because journeys are often several years long. After discovering a problem with the radio transmissions between Cassini and Huygens, mission controllers were able to change their plans.

How the Moon Influences the Earth
Although the moon is much smaller than the Earth, it still has an influence on its bigger companion. Just as the Earth’s gravity pulls on the Moon, the gravity of the Moon pulls on the Earth, stretching it into a slight oval. This distortion barely affects the solid landmasses, but it makes the oceans bulge on either side of the planet, producing the tides on either side of the planet. ...
