7:56 PM | The Many Resurrections of the Hubble Space Telescope
If you are old enough to remember news stories from 1990 (or if you are a devoted student of astronomy), you'll recall that the Hubble Space Telescope was not always regarded as the technological triumph that NASA is loudly celebrating today, on its 25th anniversary. The orbiting observatory debuted as a king-size disaster: the telescope that couldn't see straight, built with a mirror that was ground perfectly...but perfectly incorrect. The story of how the error was discovered and ultima

4:43 PM | Stalled Hawaiian observatory shows what stalled Indian observatory is losing out on
Hundreds of protesters took to the streets against the construction of the observatory. The mountain’s surroundings that it would occupy were held sacred by the local population. Even after the project had cleared a drawn-out environmental review that ended with a go-ahead from the government, the people expressed their disapproval – first at the ground-breaking […]

Originally posted on International Year of Light Blog:Today we celebrate the 25th anniversary of the launch of the Hubble Space Telescope. Hubble is hardly the first telescope: ever since Galileo, astronomers have used telescopes to study the sources of light from the universe, near and far. Stars, galaxies, nebulae, and planets too far away…

11:00 AM | Giant Leap...
International Space Station - Facts and Figures PageTopics: International Space Station, NASA, Space, Space ExplorationGrowing up in the Apollo era, spaceflight and space exploration were "big deals" that stopped traffic, ensued water cooler conversations and dominated - at least in nerd culture - deep thoughts regarding where we were heading. It wasn't until the Space Shuttle Program that spaceflight became humdrum; routine. We'd pause when Challenger or Columbia tragedies dominated the news […]
