Galaxy Facts

The largest galaxies have nearly billion stars. There are an estimated   billion stars in the milky way, our galaxy. If you tried to count all the stars in just our galaxy at a rat of one star per second, it would take you about 3000 years.

Looking Inside the Sun
The Sun is our nearest star. It is a huge, luminous ball of gas like all the other stars. It consists mostly of hydrogen, and helium with tiny amounts of other elements. The Corona is the outer shell of the Sun’s atmosphere. It is extremely hot with temperatures reaching up to 2 million degrees. In the radiation zone, the energy is transported outwards by radiation. It covers about 70% of the Sun’...

Space examination or the Space missions is the disclosure and examination of space by system for space mechanics. Physical examination of space is administered both by human spaceflights and by robotic shuttle. While the observation of articles in space, rumoured to be Astro science, starts before reliable recorded history, it was the development of unbelievable and similarly profit...
Other Solar Systems
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 ...

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.
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.

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...
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...

Galileo Galilei is ordinarily...
Atomic Discovery
Atomic theory is a theory of the nature of matter, which states that matter is composed of discrete units called atoms, as opposed to the obsolete notion that matter could be divided into any arbitrarily small quantity. The Atoms are subdivided into Nucleus. The Nucleus is formed with thousands of Nucleons. The Nucleons are again subdivided into Quarks. No matter how these are discovered, these di...
Fun Facts About the Space Shuttle
Finding out the length of an orbit is a very tedious task. Unless one have flown aboard the space shuttle or have seen it in person, it can be difficult to mentally visualize the size of the vehicle. Here, we measure the orbiter against a familiar object, a school bus. The weight of Orbiter would weight around 178000 pounds. The heaviest African Elephant weighs 13200 pounds. It would take appro...

The plaques demonstrate the bare figures of a human male and female as well as a few images that are composed to give informative da...
