“BBC News has an article detailing NASA’s replacement for the much-loved Hubble telescope. The $4.5 billion telescope will be placed in orbit 1.5 million km from Earth and will be almost three times the size of the Hubble. It is set to launch in 2013. They also plan to service the Hubble in 2008.”

(Dec 23, 2005) NASA’s Hubble Space Telescope has helped discover new rings and two small moons orbiting Uranus. The largest ring is twice the size of the planet’s previously known rings, and went undiscovered until now because they’re so far away from the planet. Scientists think that particles in these rings are slowly spiraling away from Uranus, so there must be some source constantly replenishing them with new material.

JohnnyNapalm writes “The Aggie Daily News is reporting today that the first mirrors have been cast for the world’s largest telescope. The result of cooperation from some of the foremost institutions in education and science in the nation, the Giant Magellan Telescope stands to operate at a resolution 10 times larger than the Hubble. The project, set to be constructed in Chile, is slated for completion in 2016.”
