NASA Image. Stunningly beautiful and damn cool.

'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.

Goodness, gracious. Great ball of fire.

Update: In this Wikipedia article, there is a great chronicle of the recent solar events.

This incredible NASA image came juuuust too late for my prior post about the current uptick of solar activity. Dag-namit.

On August 1, 2010, almost the entire Earth-facing side of the sun erupted in a tumult of activity. This image from the Solar Dynamics Observatory of the news-making solar event on August 1 shows the C3-class solar flare (white area on upper left), a solar tsunami (wave-like structure, upper right), multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a coronal mass ejection and more.

This multi-wavelength extreme ultraviolet snapshot from the Solar Dynamics Observatory shows the sun’s northern hemisphere in mid-eruption. Different colors in the image represent different gas temperatures. Earth’s magnetic field is still reverberating from the solar flare impact on August 3, 2010, which sparked aurorae as far south as Wisconsin and Iowa in the United States. Analysts believe a second solar flare is following behind the first flare and could re-energize the fading geomagnetic storm and spark a new round of Northern Lights.

This terrifies me.

NASA Mars rover "Curiosity"

"Mars rover Curiosity, the centerpiece of NASA's Mars Science Laboratory mission, is coming together for extensive testing prior to its late 2011 launch. This image taken June 29, 2010, shows the rover with the mobility system -- wheels and suspension -- in place after installation on June 28 and 29. Spacecraft engineers and technicians are assembling and testing the rover in a large cleanroom at NASA's Jet Propulsion Laboratory, Pasadena, Calif. Curiosity's six-wheel mobility system, with a rocker-bogie suspension system, resembles the systems on earlier, smaller Mars rovers, but for Curiosity, the wheels will also serve as landing gear. Each wheel is half a meter (20 inches) in diameter." Image by NASA.
