Shuttle launch schedule of 2009 has reached to a new corner point today as Atlantis is scheduled for launch today at 2PM EST. Atlantis is set to launch at 2:01 p.m. EDT on a mission to upgrade the world's most famous telescope.

Two of our Galaxy's most massive stars have been scrutinised in an impressive view by the NASA/ESA Hubble Space Telescope. They have, until recently, been shrouded in mystery, but the new image shows them in greater detail than ever before.

The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern.

NASA scientists and a space shuttle astronaut today outlined details of a challenging mission that will repair and upgrade the Hubble Space Telescope in 2008.

A significant milestone for the Hubble Space Telescope successor, the James Webb Space Telescope (JWST), is on course to be reached before Christmas with the testing of the verification model of the Mid-InfraRed Instrument (MIRI) at the Rutherford Appleton Laboratory in Oxfordshire.

Bill Dillon, an avid amateur astronomer and past president of the American Association of Variable Star Observers (AAVSO) with many years of extensive hands-on experience, created a new first for amateur astronomy.

The NASA/ESA Hubble Space Telescope has probed the bright core of Comet 17P/Holmes which, to the delight of sky watchers, mysteriously brightened by nearly a million-fold in a 24-hour period beginning October 23, 2007.

New images taken with NASA’s Hubble Space Telescope – part of a research project led by UC Riverside’s Gabriela Canalizo – have revealed the wild side of an elliptical galaxy, nearly two billion light-years away, that previously had been considered mild-mannered.

Nearly 12.5 million light-years away, in the dwarf galaxy NGC 4449, stellar fireworks on display have been captured by the Hubble Space Telescope.

Hundreds of thousands of vibrant blue and red stars are visible in this new image of galaxy NGC 4449 taken by the NASA/ESA Hubble Space Telescope. Hot bluish white clusters of massive stars are scattered throughout the galaxy, interspersed with numerous dustier reddish regions of current star formation. Massive dark clouds of gas and dust are silhouetted against the flaming starlight.

The NASA/ESA Hubble Space Telescope has delivered an unrivalled snapshot of the nearby barred spiral galaxy NGC 1672. This remarkable image provides a high definition view of the galaxy's large bar, its fields of star-forming clouds and dark bands of interstellar dust.
