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.

As substances, heavenly figures have matter (aether) and a shape: it appears that Aristotle did see them as living creatures with a reasonable soul as their shape.

All of the stars in “The size of our world” and all the stars you can see in the sky are only in our own galaxy ! What lies beyond our galaxy? It is a great miracle to know about these facts. The Hubble space telescope kept its camera pointed there for over 4 months, taking in all the light it could.

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.

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.
