![]() ![]() ![]() There are now other telescopes in orbit, like the Herschel Space Observatory and the Kepler Spacecraft, which was specially made for finding Earth-like planets around other stars. Hubble will be replaced by the James Webb Space Telescope which will be located even further from Earth. It took the first picture of a planet outside our solar system, and was able to find what type of atmosphere other planets might have.Before the Hubble, scientists only knew it was between 10 and 20 billion years old. It was able to help settle the age of the universe at about 13.7 billion years.In 2004, Hubble looked back several billion years to the first galaxies in the Hubble Ultra Deep Field.It found there were actually many galaxies even there, but very faint and very far away. Early on, in 1994, Hubble stared at what was thought to be an empty area of space for ten days.Sombrero Galaxy in infrared light (Hubble Space Telescope and Spitzer Space Telescope) The astronauts had to think of a creative way to get around the problem. When an astronaut opened one of the doors on Hubble to install a new camera, the door would not close. NASA science games, articles and activities for kids. The astronauts had to install some small mirrors to correct the light from the big mirror. RepairĪnother space shuttle was soon sent up to repair the space telescope. Still, this was enough to cause the images to be blurred. It was only wrong by 2.2 microns (1/50th as thick as a piece of paper). They found a problem with the telescope's mirror. Telescopes in space can take better pictures than telescopes on Earth, but for some reason, the pictures were not better than the pictures taken on Earth. When the HST took its first pictures, astronomers were happy to see the images, but they were not as sharp and as crisp as expected. Improvement in Hubble images after SM1 Problems It was repaired in 1993 due to problems in the picture quality. The Hubble itself is the size of a large school bus, but still small enough to fit inside the cargo bay of a Space Shuttle. This speed creates difficulty in scheduling observations. If you were going this speed on Earth, you would be able to get from New York to San Francisco in 10 minutes. Like other things in low Earth orbit it travels at 5 miles (10 km) per second. It is 600 km in space and was launched on April 24, 1990. It was made by both NASA and the ESA working together. The telescope can take pictures of things so far away it would be nearly impossible to see them from anywhere else. What Is the Hubble Space Telescope The Hubble Space Telescope is a large telescope in space. ![]() The main mirror is 94.5 inches (2.4 meters) across. Named after the astronomer Edwin Hubble, the Hubble Space Telescope can observe 24 hours a day. The atmosphere blurs starlight before it reaches Earth. See the fact file below for more information about the Hubble. Being above the atmosphere means it can see the sky more clearly than a telescope on the ground. Named after the astronomer Edwin Hubble, the Hubble Space Telescope can observe 24 hours a day. The Hubble Space Telescope (HST) is the first big optical space observatory telescope. One of the most famous images taken by the Hubble telescope: the "Pillars of Creation" in the Eagle nebula ![]()
