The Hubble Telescope has been orbiting Earth for 20 years, transmitting pictures of the universe that stun and amaze. Observation of the most ancient universe ever detected and pictures of asteroids colliding in deep space are a couple of of Hubble’s recent discoveries. The Hubble Telescope’s run of discovery will end in 2014 when it is replace by the James Webb Space Telescope, a larger, much more advanced instrument that will make Hubble’s amazing achievements seem quaint.

Most ancient universe image from Hubble
Hubble Telescope astronomers announced Friday that they’ve seen the oldest object ever found in the universe. According to the NY Times, a galaxy gave off light that took 13.1 billion years to get to Earth. It had been then detected on an image this year from the Hubble. The universe was only 600 million years old at the time it left. Many astronomers have theorized that it had been a really early on universe. They also believe that the Hubble observed it in a form it no longer exists in.
Hubble asteroid crash pictures
The first asteroid collision photos were taken by the Hubble last week. The Christian Science Monitor accounts that the images offer clues about what to expect when asteroids slam together. If an asteroid ever threatens Earth, scientists may be able to devise plans on what to do. 2 asteroids about the size of 10 to 16 feet hit one another going at a speed of 11,200 mph, astronomers estimated. The blast of the 2 rocks hitting each other had been huge. It had been just like a small nuclear blast. The pressure made the debris of the smaller rock which vaporized became like a tail behind the larger rock.
Then there’s the Webb telescope
Four times farther than the moon, at 940,000 miles away from Earth, the Webb Space Telescope can be sent to a stable point as the Hubble Telescope successor. Places in points were the gravity from the Sun and Earth intersect are called Lagrange points. This can be a place where orbit can happen. It is where the Webb Space Telescope will be. From this fixed position, operating at a temperature of absolute zero, its two-story tall mirror can be able to observe the birth of the universe and open a new era of space exploration.
