The "Cat's Eye" nebula like you've never seen it before....

A novel Antarctic telescope with 16-m diameter mirrors would far outperform the Hubble Space Telescope, and could be built at a tiny fraction of its cost, says a scientist from the Anglo-Australian Observatory in Sydney.

For the first time, scientists have peered at the stars using the newly installed telescope aboard NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA), the largest airborne observatory in the world.

A stunning image released this week by the Gemini Observatory captures the graceful interactions of a galactic ballet, on a stage some 300 million light years away, that might better be described as a contortionist's dance.

Scientists who conducted the preliminary assessment of the Genesis canister are encouraged by what they see. They believe it may be possible to achieve the most important portions of their science objectives.

A nearby galaxy cluster is facing an intergalactic headwind as it is pulled by an underlying superstructure of dark matter, according to new evidence from NASA's Chandra X-ray Observatory.

Here's the latest advaisory, straight from NOAA...

Astronomers have announced the first discovery of a new class of planets beyond our solar system about 10 to 20 times the size of Earth - far smaller than any previously detected. The planets make up a new class of Neptune-sized extrasolar planets.

Only days after Guinness World Records certified the prior flight of NASA's X-43A hypersonic technology demonstrator aircraft as a world speed record, a full-scale dress rehearsal for the last and even faster flight of the small unpiloted research aircraft is tentatively scheduled to occur on Tuesday, Sept. 7 from NASA's Dryden Flight Research Center.

Spend a photo-virtual Summer at Kitt Peak

In a dramatic ending that marks a beginning in scientific research, NASA's Genesis spacecraft is set to swing by Earth and jettison a sample return capsule filled with particles of the Sun that may ultimately tell us more about the genesis of our solar system.

Photo by MODIS (Moderate Resolution Imaging Spectroradiometer) MODIS is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites.

Aug. 28 Ceremony at Black Rock Mesa for $18 Million Observatory

A team of planet-hunters will announce their discovery of a new class of planets beyond our solar system at a NASA Science Update at 1 p.m. EDT on Tuesday, August 31. Their discovery represents a significant and much-anticipated advance in the hunt for extra-solar planets.
