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.

Interplanetary Travel
The planets are very far away. A spacecraft traveling at 60 mph a typical speed of a car on a highway – would take about 60 years to reach Mars. Fortunately, rockets travel much faster than this. The Voyager spacecraft sped from the Earth at 32000 MPH. But even at this speed, travel to the planets takes a long time. The Future space colonies will have to be self – sufficient, growing t...

Driving Force That Drives Galaxies Apart
The universe is expanding at an ever – increasing rate, with something that astronomers call dark energy appearing to push it apart faster than gravity can pull it together. Type la supernovas are stars that explodes with a predictable brightness. Light from distant supernovas locks dimmer and redder than expected, implying that the universe is expanding. The more distant the star, the fast...

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.

Red Giant Stars Explained
A red monster is an iridescent monster star of level or halfway mass (harshly 0.5–10 sun oriented masses) in a late stage of stellar development. The external environment is swelled and tenuous, making the span monstrous and the surface temperature flat, an as yet undisclosed place from 5,000 K and easier. The manifestation of the red monster is from yellow orange to red, incorporating the unearth...

Neptune is the eighth and most distant planet from the Sun in the Earth's planetary group. It's the fourth-most expansive planet by distance across and the third-most vast by mass. Neptune is 17 times the mass of Earth and is to some degree more enormous than its close-twin Uranus, which is 15 times the mass of Earth but not as dense. On normal, Neptune circles the Sun at a separation of 30...

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....

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.

How Eclipses of the Sun Happen
In its 27 – day Orbit of the Earth, the Moon sometimes passes directly in front of the Sun and we see a solar eclipse. In one of the natural world’s most eerie, beautiful spectacles, the dark circle of the Moon gradually creeps over the Sun. Between two and five solar eclipses are visible from somewhere on the Earth each year. When the Moon is at its farthest from the Earth, it is not ...
