Saturn Moons photographed by Cassini
Enceladus is geographically active moon of Saturn. Its graphical structure varies frequently due to immense gravitational pull of Saturn. This stunning image was taken on Oct 5, 2008 by Cassini spacecraft.
Cassini spacecraft's view of Saturn's moon Janus. This moon is 179km across.

1200 ExoPlanets found
Exoplanets are those planets that reside outside our solar system. That belong to other stars. A NASA telescope has registered(found) 1200 planets inside our Milky Way. Out of these, 54 planets reside in the Habitable Zone. This data is collected by keplers telescope in just four months of work. 200 systems are multi-planet system.
Kepler telescope located about 2000 light years from earth. When a planet orbits a star, it passes from front side of star and then back side of star. When planet passes from front of star, light of star dims slightly. Brightness of star increases when planet is at backside of star. By measuring the difference between the brightness, we can know the presence of planet around a star. Kepler is sampling 156,000 stars like the sun. It take a long time to get the full data about a planet. Because, complete information is available only after 1 or 2 revolutions around the star. Earth like planets take 365 days for one revolution. Therefore Kepler telescope continue the examine the planets for more data. Kepler has only studied the 1/400th of the sky. It also take more time to measure planets away from stars. From all this info, we can say life ought to be very common in the universe.Birth of solar system - educating video
Science videos are very cool! we learn a lot by watching. If you like it, please post your thoughts.
Black Hole eating a Star
Power of a Black Hole is evident from this video. Just awesome, Check out!
Black hole is the most interesting object in the universe. It is very small in size compared to stars, yet the star is completely compressed and is completely swallowed by it. If any suggestion or query then feel free to comment. Can you tell how long would it take a black hole to completely absorb a average star?
Eye Of Mankind -- Hubble
Hubble telescope is 559 Km above from the surface of earth. It is orbiting around the the planet completing one revolution in 97 minutes. Telescopes on the surface of earth have limited visibility due to the atmosphere, hence solution to this problem was to send the telescope outside the atmosphere. Here are some images of the thing that provided us incredible images of other worlds throughout the universe.
Amazing wonder of science is running at 8 km per second, such a high pace and still its able to focus to distant object. Images provided by hubble can be seen at following links:

Not Just NINE Planets
Our solar system consists of lot more stuff than just Nine planets. I use the word our solar system!! yes there are lots of solar systems as well as planets in the Universe. Nine planets are the known to a lot of people, but they ignore the presence of other stuff like comets, asteroids, moons, dwarf planets.
If we take a look just about 4 billion years ago, when planets were just born, comets play an important role in helping to make Earth suitable to sustain life. Asteroids also occupy an important place in the history of Earth. I don't think other 8 planets had any major role in sustaining the life on Earth of course Jupiter is an exception. Jupiter is saving earth from outer space dangers by its strong gravitational pull.
There is no way to miss our Life giver The Sun. Which is the big boss of Solar System, but just a small part of Galaxy we live in Milky Way. It's the center of attraction for every object that exists in this planetary system(Solar system). Our Sun is almost 5 billion years older. And equal ammount of time is remaining in the life of our Sun.
Here are some Shots of Non-Planet objects of solar system.
