Explore universe with microsoft's free world wide telescope.You too can be an astronomer.Evenn 6 years old can explore and walk into space.















Microsoft's world wide telescope 2008 was one of the greatest tools for astronomers and students. Exploring space is no longer hard by the microsoft's world wide telescope. microsoft's world wide telescope is built in partnership between Microsft and Next Media Research. It's a long time dream about space exploration by astronomers. Finally microsoft made it.
























One of the superstars, Microsoft stepping into its journey towards sky. Even 6 years old boy or girl can explore and share with others . It was attracted by many people around the world wich may make a way for many scientists to blossom in the future. This program help to learn more about star and solar system. Microsoft is taking people a fun way to learn. Moicrosoft is presenting worldwidetelescope absolutely free to public. It contains all type of astronomical data, community to share, on time technical support, real time update and more.

























You can feel the real sky gifited by microsoft. You can even create new collections of your own. Microsoft is also enabling your computer as a virtual telescope and you can also explore universe by web enabled browser with the help of silverlight. ASCOM platform 2008 (v5.0) is required to control the astronomy device which connects to computer.



Microsoft world wide telescope are quick to download and easy to install.



You can download microsft's world wide telescope here.



Requirements:

Microsoft .Net Framework 2.0



ASCOM platform 2008 (v5.0) required to connect telescope.



DiretX 9 or more



For Mac X OS (or) For the web client Microsoft Silverlight 2.0 is required.



Galileo Galilei (1564 - 1642) (Inventor of world's first telescope)




Galileo Galilie born on 15th feb 1564 at Pisa, Tuscany in Italy. On 4th century he invented the first in the world. The magnifying power of Galileo's telescope is about 40. On 1613 Galileo observed dark spots that appear on the sun's surface. His known for copernican observational astronomer. Even though we invent many telescope galileo galilei is the father of telescope and space exploration. He spent his last days as blind. He died on 8 january 1642.

Journey to the sun.What is inside the sun?Finally scientists got the sun's sample














Do you believe it is possible to reach sun? The outer most part of the sun raises to several million degrees.


Parts of the sun:



1. core : The inner center layer.

2. Radiative zone : The second layer next to core.

3. Convection zone : The third layer next to aiative zone.

4. Subsurface's flows : The fourth layer next to convection zone.

5. photosphere : The outer surface of the sun.

6. chromosphere : Outer coating of the photosphere.

7. corona : The outer most part of the sun.


Temperature :

The inner center layer of the sun is called core. It is about 15.6 billion k ie, 20 million degrees. The outer most surface of the sun is photosphere. It is about 5800k. The outer most part of the sun is called corona. The temperature of the corona ms to several million degrees.




Journey to the sun:
On August 8th 2001 NASA launched genesis probe to collect the sample of the sun. It is impossible to take sample from the sun because the probe will melt if it reaches before several million miles away from the sun due to a high. How they did it? The genesis probe is designed by several foils like gold, etc to collect the electrons from the sun. Genesis collected particles from the sun's solar wind before several miles away.




After 3 years of genesis launched it collected samples for 884 days. It returns home on 8th Sept 2004. The genesis probe entered the earth totally out of control. It crashed into the earth with the speed of 11.04 kilometers per seconds. Finally genesis hits the surface of the earth and opened. Scientists thought it is the saddest mission ever before.










Luckily, the collected samples are safely inside the gold foil with some impurities. Research on the collected samples by genesis contains atoms and ions. According to the research made by the Johnson's space center, most of the sun is made up of hydrogen. They not only found hydrogen. Among them they also found SI, O, C, N, Mg, Fe among billions of collected solar samples.
Our body is created of Co2 which originates from the star.



Einstein's Formula (E=mc2) :


Four (4) hydrogen (H) nuclei fuse to form a single helium (He) nucleus. Helium (He) is lighter than four (4) hydrogen (H) nuclei. The missing material which is responsible for the losses of weight is converted under Einstein's formula E = mc2 . A pure glowing energy is given out. It is called photons.


Each and every sun beam is full of photon. The second layer of the sun is called radiative zone. The photons are bounded around by a particle of hot hydrogen gas called plasma. The outer surface of the sun is called photosphere where photons are emitted. These photons travel about 93 million miles journey to earth in just 8 minutes and reach earth as sunshine.
