Is our Solar system unique in the Universe ? Until recently, astronomers could only guess whether other stars are orbited by planetary systems. Extrasolar planets – those that orbit stars other than the Sun – are difficult to detect, because they are about one – billionth the brightness of their parent stars.
Extrasolar planets can also be detected by watching for a drop in brightness as a planet transits, or passes in front of, its parent star. The changing brightness of the star can be plotted on a graph called a light curve.
Another proposal, called gravitational microlensing, is to watch for sudden brightening as the planet’s gravitational field acts like a lens and magnifies the light from a more distant star.

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...

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....

How to Understand Relativity
Spacetime is CONSTANT (always 100%). Both time and space are maileable – they can change within spacetime, but no matter how big or small one part is, THE TOTAL IS ALWAYS 100% - so TIME TRAVEL IS POSSIBLE, in fact, we’re ALL traveling through time right now !!!!!

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.

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.

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.
