‚Island Universe‘ in the Coma Cluster

A long-exposure Hubble Space Telescope image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light- years away in the northern constellation Coma Berenices. The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. The high resolution of Hubble’s cameras, paired with considerably long exposures, made it possible to observe these faint details.
This natural-color Hubble image, which combines data obtained in 2006, 2007, and 2009 from the Wide Field Planetary Camera 2 and the Advanced Camera for Surveys, required 28 hours of exposure time.

Wild 2: If You Were There

On Jan. 2, 2004 NASA’s Stardust spacecraft made a close flyby of comet Wild 2 (pronounced „Vilt-2“). Among the equipment the spacecraft carried on board was a navigation camera.that Comet Wild 2 is about 3.1 miles in diameter.

This artist’s concept depicts a view of Wild 2 that shows the faint jets emanating from the comet.

This future aircraft design concept for supersonic flight over land comes from the team led by the Lockheed Martin Corporation.

The team’s simulation shows possibility for achieving overland flight by

dramatically lowering the level of sonic booms through the use of an „inverted-V“ engine-under wing configuration. Other revolutionary technologies help achieve range, payload and environmental goals.

This supersonic cruise concept is among the designs presented in April 2010 to the NASA Aeronautics Research Mission Directorate for its NASA Research Announcement-funded studies into advanced aircraft that could enter service in the 2030-2035 timeframe.
