Hubble Space Telescope views detail of star formation.
After being forced to turn back earlier this week because of an air leak, Mike Fincke and Gennady Padalka were able to complete their spacewalk on Wednesday. The two men spent 5 hours, 40 minutes outside the International Space Station, and they were able to install a new circuit breaker which restored power to one of the station's four gyroscopes. They completed the task an hour ahead of schedule, and controllers on the ground confirmed that the gyroscope had power and was functioning properly. This was the 29th spacewalk staged from the station.
New observations of Procyon from MOST, Canada's space telescope, have called long-held assumptions about the star into doubt. Launched a year ago, MOST watched Procyon 8-times a minute, making a total of 250,000 observations over the course of 32 days. It found that the star is completely stable, and doesn't pulsate or vibrate in any way. This challenges 20 years of speculation that Procyon does vibrate, and could reveal insights about its interior - Astronomers will need to find a new candidate.
NASA's Hubble Space Telescope captures this iridescent tapestry of star birth in a neighboring Galaxy in this panoramic view of glowing gas, dark dust clouds, and young, hot stars. The star-forming region, catalogued as N11B, lies in the Large Magellanic Cloud (LMC), located only 160,000 light-years from Earth. With its high resolution, the Hubble Space Telescope is able to view details of star formation in the LMC as easily as ground-based Telescopes are able to observe stellar formation within our own Milky Way galaxy. This new Hubble image zooms in on N11B, which is a small subsection within an area of star formation cataloged as N11. N11 is the second largest star-forming region in the LMC. Within the LMC, N11 is surpassed in size and activity only by the immense Tarantula nebula (also known as 30 Doradus.)
Seven years after it set out from Earth, the Cassini spacecraft finally arrived safely at Saturn. Using its high-gain antenna to protect it from dust particles, the spacecraft crossed the ring plane early Thursday morning at 0203 UT (10:03pm EDT Wednesday). It fired one of its twin main engines for 96 minutes to slow down its velocity, and then pointed at Earth to transmit news of its successful arrival. The spacecraft then took detailed images of Saturn's rings, as Cassini isn't scheduled to ever get this close to them again. Cassini will now begin its 4 year mission to analyze Saturn and its moons.
