Before the Hubble Space
Telescope, people saw the field of astronomy differently than
they do today. American spacecraft did provide
detailed pictures of Jupiter and Saturn, planets in our own solar system. But deep
space, the place where nebulae and
galaxies
exist, remained mostly colorless -- until the Hubble Space Telescope. It has
provided detailed and often colorful images of once unimaginable objects. Friday
marks 25
years since Hubble left the ground. It was launched on the American space
agency’s Space Shuttle Discovery. The agency, also known as NASA, says the
telescope can no longer be repaired in space. But a new space telescope, the
James Webb Space Telescope, is being built and tested. Plans call for it to be
launched from French Guiana in October of 2018.

The Hubble and the Webb telescopes
have much in
common. Scientists designed both to operate in the
vacuum of
outer
space. In other words, they can work in an environment
without air. Both telescopes use mirrors to collect and redirect light to make
pictures, and radio signals to send these images back to earth. And both are
powered by sunlight. However, NASA officials say the James Webb Space Telescope
is different from Hubble. Matt Greenhouse is a project scientist for the Webb
telescope. “The Webb, as we call it, is the successor to Hubble Space
Telescope, and it is designed to do science that the Hubble can’t do
by virtue
of its design. One of the biggest differences between the
Webb and the Hubble is that the Webb is designed to be an infrared telescope to see
these very primordial objects, these
objects that are among the oldest objects in the universe.”
