But the telescope does have various filters that can be applied to let in only a specific wavelength range, or color, of light.

Spectacular Photos From The Revamped Hubble Space Telescope, Images - Spectacular New Photos From the Hubble Telescope, Astronauts' Choice: Hubble Telescope's Best Cosmic Views, Pictures from space! The most recent visit was in May 2009, when astronauts performed five tricky spacewalks to add a new camera, spectrograph, and make unprecedented repairs and upgrades that left Hubble more powerful than ever before. The Hubble Space Telescope launched in April 1990 and has been visited by NASA astronauts multiple times for vital repairs, maintenance and upgrades. And if you have a news tip, correction or comment, let us know at: community@space.com. New York, Hubble's CCD cameras don't measure the color of the incoming light directly. Hubble doesn't use color film (or any film at all) to create its images. What happens at the center of a black hole? The nearly 20-year-old Hubble Space Telescope has taken many iconic images of the cosmos and is even the star of a new 3D IMAX movie that gives viewers a chance to fly through those snapshots. But does Hubble show us what the universe really looks like? But the telescope does have various filters that can be applied to let in only a specific wavelength range, or color, of light. You will receive a verification email shortly. Scientists can then combine the images, assigning blue light to the data that came in through the blue filter, for example, red light to the data read through the red filter and green light to the green filter, to create a comprehensive color image.

NASA scientists hope those upgrades will add at least five more years of life to the aging Hubble Space Telescope. When Hubble beams down images, astronomers have to make many adjustments, such as adding color and patching multiple photos together, to that raw data before the space observatory's images are released to the public. © For example, Hubble photographed the Cat's Eye Nebula through three narrow wavelengths of red light that correspond to radiation from hydrogen atoms, oxygen atoms, and nitrogen ions (nitrogen atoms with one electron removed).

For some Hubble photos, such as the galaxy ESO 510-G13 for example, the end result is a close approximation of the colors people would see with their own eyes were they to visit the distant sight in a spacecraft. The observatory will often take photos of the same object through multiple filters. "Creating color images out of the original black-and-white exposures is equal parts art and science," NASA said. It takes a telescope, letting light build up in its CCD over time, to see the rich hues in Hubble photos. Space is part of Future US Inc, an international media group and leading digital publisher. [Spectacular Photos From The Revamped Hubble Space Telescope]. On This Day in Space: Oct. 27, 1961: NASA launches 1st Saturn rocket test flight. Instead, it operates much like a digital camera, using what's called a CCD (charge-coupled device) to record incoming photons of light.

Hubble can detect light throughout the visible spectrum, plus ultraviolet and infrared light which is invisible to human eyes. "We often use color as a tool, whether it is to enhance an object's detail or to visualize what ordinarily could never be seen by the human eye," NASA officials explain on the agency's Hubble Web site.

In real life, those wavelengths of light would be hard to distinguish for humans. [Most Amazing Hubble Discoveries ]. Though even these photos are an enhanced version, since most celestial objects, such as nebulas, emit colors that are too faint for human eyes to make out. In that case, they assigned red, blue and green colors to the filters and combined them to highlight the subtle differences. Join our Space Forums to keep talking space on the latest missions, night sky and more! Three thousand light-years away, a dying star throws off shells of glowing gas in this image from the Hubble Space Telescope of the Cat's Eye Nebula. And for other Hubble images, scientists assign colors to the filters that don't correspond to what that light would look like to human eyes. They do this when using light from infrared and ultraviolet filters, since those wavelength ranges have no natural colors, or when combining light from slightly different shades of the same color.
