The Hubble telescope cannot take pictures of Earth because the minimum exposure time is 0.1 seconds, during which time the Earth would move around 700 meters making the image streaked. After enhancement, NASA releases the photographs to the public following a process that takes about six months. When the Hubble telescope transmits data, it is in digital form computers then have to convert this data into black and white photos. You can see what Hubble is observing at any moment via the “live” website, but these images are only used as a guide and usually come from other telescopes. Some pictures from the Hubble telescope are as close to the natural colors as possible, while other images use color to represent different elements, such as heat.Īnd there are no “live” images from Hubble. The Hubble telescope doesn’t possess any color cameras the digital CCD cameras take grayscale images but use filters to isolate various colors. Telescopes on Earth are subject to atmospheric distortions and light blockages this means space is the only place where astronomers can see an actual image of the Universe. The purpose of the Hubble telescope is to give scientists an accurate picture of the Universe. NASA launched the telescope on April 24, 1990, before deploying it into orbit the following day. The Hubble telescope is named after the American astronomer Edwin Hubble, who made several important modern-day astronomical discoveries.
