When the Hubble Space Telescope (HST) was launched 1990,
even HST's team of astronomers couldn't imagine the spectacular views and discoveries that
HST would give us, including the birth of stars billions of years ago.
A space shuttle mission
in February, 2009 will upgrade HST to be 90 times more powerful, giving
us views of more distant galaxies than ever.
In 2013,
HST will be replaced by the
James Webb Space Telescope, with a
mirror size of 21 feet compared to HST's 2.5 feet!
What is a Light Year? -
Distances to stars/galaxies are measured
to in light years, or how far light travels in a year at 186,000 miles
per second. For a perspective of distances,
