The Milky Way

I love to read about Milky way, so I think this is an interesting info.

On Clear nights, far from town when there in so moon, a faint, hazy white  band can be seen stretching right acroos the sky. This band is called the Milky way. Through binoculars, it is clear that the milky way consists of countless starts - indeed, it is a vast cluster of over 100 billion stars. The milky way appears to us as a narrow band because we are looking at it edge on. If we could look down on it, we would see that it looks like a giant catherine wheel, with a dense bulge at its centre containing mostly older stars.

Hubble 3D Blasts Off Again

Hubble 3D will open in additional IMAX theaters on Aug. 20, and will play for a special limited time engagement. The film, which debuted on March 19, initially launched in 55 domestic and 15 international IMAX locations to rave reviews from critics and audiences alike.

Narrated by award-winning actor Leonardo DiCaprio, the film documents the STS-125 shuttle mission to upgrade the Hubble Space Telescope. The film is a joint venture between NASA, the IMAX Corporation and Warner Bros. Pictures.

"Thanks to our wonderful partners at Warner Bros. and NASA, Hubble 3D offered us the opportunity to take audiences on an astounding, immersive journey -- from the thundering launch into space to witness first-hand the astronauts' mastery at performing 'brain surgery' on Hubble, all the way to the outer edges of our universe in groundbreaking flythroughs," said producer/director Toni Myers. "We are gratified that the film was so well received during its initial launch, and we are very excited that more people will have the opportunity to learn about Hubble’s amazing discoveries."

The IMAX 3-D cameras launched aboard space shuttle Atlantis on May 11, 2009, during the STS-125 mission to repair the Hubble Space Telescope. Astronauts documented the mission's five spacewalks to repair and upgrade Hubble and the IMAX footage was combined with breathtaking detailed images of distant galaxies from Hubble.

Atlantis' crew--Commander Scott Altman, pilot Gregory C. Johnson and Mission Specialists Andrew Feustel, Michael Good, John Grunsfeld, Mike Massimino and Megan McArthur--were the fifth shuttle crew to fly to the telescope. Their predecessors have replaced and repaired failed and faulty components and added new and improved cameras and scientific equipment, and the STS-125 crew will be no different.

The IMAX team trained Atlantis' crew at NASA's Johnson Space Center in Houston to operate the cameras. One was mounted outside the crew cabin in the shuttle's cargo bay to capture IMAX 3-D images of the historic final servicing mission. The commander and pilot will double as filmmakers as two teams of spacewalking astronauts -- working in tandem with the shuttle's robotic arm -- perform some of the most challenging work ever undertaken in space as they replace and refurbish many of the telescope's precision instruments.

"This is star travel," said Myers. "You"re right out there, moving in space. The Hubble Telescope has amassed a monumental amount of data from the distant reaches of the cosmos, the birth of solar systems and ultra deep field galaxies beyond our own. That data has been turned into three-dimensional flights to transport audiences to the edge of the observable universe in a way most people have never even imagined."

Through the world's most immersive cinematic experience, Hubble 3D will give audiences a front row seat as the story unfolds. It will reveal the cosmos as never before, allowing viewers of all ages to explore the grandeur of the nebulae and galaxies, the birth and death of stars, and some of the greatest mysteries of our celestial surroundings, all in IMAX 3-D.

IMAX's longstanding partnership with NASA has enabled millions of people to travel into space through a series of award-winning IMAX films. The IMAX 3-D camera made its first voyage into space in 2001 for the production of Space Station 3D.

Big Bang!

1. At first, the entire universe was a hot ball tinier than an atom and much hotter than any start. This swelled much, much faster than the speed of light, growing to the size of a galaxy in just in a tiny fraction of a second.

2. As the universe expanded, it began to cool and tiny particles of energy and matter each of them much smaller than atoms-began to form a thick, soup-like material.

3. After about three minutes, gravity started to pull the particles together. Atoms joined together to make gases such as hydrogen and helium, and thick soup began to clear and thin out by the end of the third minute, the matter that surrounds us today had been created.

What is the beginning for all??

By measuring the age of meteorites (rocks that fall to earth from space), scientists have worked out that the Solar system is about 4.6 billion years old. When it began to form, it was a  whirling mass of stardust and gases, but as it spun around quickly, gravity began to pull it tighter together. Eventually, the dense centre formed the Sun and dust further out gathered into lumps, which became the planets.
