These swirling hydrogen clouds are given their stunning colors by the intense ultraviolet radiation emanating from the newborn stars within. And that massive star right in the middle is so radiant that it's changing the shape of this nebula. This is the nebula NGC 2467, located some 13,000 light-years from Earth. First discovered in the nineteenth century, the nebula lies within the constellation Puppis in the southern hemisphere. The image you see up top (click on it to see the ultra high-res version) was assembled from images taken by the Hubble Telescope back in 2004. Three different color filters were used to bring out the full majesty of the nebula. Still, NGC 2467 isn't just beautiful - it's also a working lesson in astrophysics. The new stars shine more brightly than they ever will again, emitting so much radiation that the surrounding clouds of hydrogen gas begin to erode. In particular, the huge, bright star in the upper center of the image is responsible for most of the radiation emanating from the nebula. It's clearing away massive amounts of the surrounding cloud, and this processes pushes the denser regions of the nebula elsewhere. Although some of the new stars are shining through, many more are still hidden behind the clouds, just waiting to make their first appearance to Earth astronomers. http://spacetelescope.org/videos/heic1012a/

Imagine a magnetically-bound tube of hot gas, 12,000-miles long and a hundred miles wide, moving at 30,000 miles per hour: That’s what you’re looking at in the picture above, in the highest-resolution image to date of solar phenomena known as spicules. Tens of thousands of spicules are active at any given moment, created through a complex interaction of sound waves and magnetic fields, shooting upwards and outwards before falling back into the sun minutes later. They compose the chronosphere, an atmospheric layer that surrounds the sun and is as thick as the Earth’s diameter. Most of our own atmosphere is compressed into a layer about seven miles deep. It’s sometimes easy — for me, anyways — to forget that the sun is 93 million miles away, and that Earthly life exists through the coincidental good fortune of our planetary rock’s location, neither too far nor too close to that ball of gas. This photograph, taken by the Swedish 1-m Solar Telescope, a good reminder.

In this zoom sequence we start with the spectacular vista of the central regions of the Milky Way galaxy. We then close in on a fuzzy ball of stars, the globular cluster Messier 107, also known as NGC 6171. It lies about 21,000 light-years away in the constellation of Ophiuchus. The final close up view was created from exposures taken through blue, green and near-infrared filters, using the Wide Field Imager (WFI) on the MPG/ESO 2.2-meter telescope at La Silla Observatory, Chile.

Watch an entire hemisphere of the sun explode
In this ultraviolet light video taken by NASA, you can watch a phenomenon that scientists didn't believe could exist until a few months ago. An entire hemisphere of the sun explodes, one region igniting another. What does this discovery mean? It turns out that the sun doesn't just spurt out gouts of gas in isolated spots. In fact, our star's magnetic field brings many regions of Sol's surface into direct relationships with each other, so areas separated by millions of miles can literally spark each other up. The results are called "sympathetic flares." lowresfilmpie: hiresfilmpie: http://science.nasa.gov/media/medial...disruption.mov http://science.nasa.gov/science-news...lobaleruption/

The 51st entry in Charles Messier's famous catalog is perhaps the original spiral nebula--a large galaxy with a well defined spiral structure also cataloged as NGC 5194. Over 60,000 light-years across, M51's spiral arms and dust lanes clearly sweep in front of its companion galaxy, NGC 5195. Image data from the Hubble's Advanced Camera for Surveys was reprocessed to produce this alternative portrait of the well-known interacting galaxy pair. The processing sharpened details and enhanced color and contrast in otherwise faint areas, bringing out dust lanes and extended streams that cross the small companion, along with features in the surroundings and core of M51 itself. The pair are about 31 million light-years distant. Not far on the sky from the handle of the Big Dipper, they officially lie within the boundaries of the small constellation Canes Venatici.

The star Zeta Ophiuchi is twenty times the size of our Sun and flying blind through space. Its runaway path has taken it through a huge clump of space dust, creating this beautiful bow-shaped "wake" of gas and dust. Zeta Ophiuchi was once the companion of another, even bigger star, but its partner went supernova. This ejected Zeta Ophiuchi from its orbit, shooting it off into open space like a humongous bullet. It is now hurtling through space at 54,000 miles per hour, and the latest part of its cosmic odyssey has taken it through this dust cloud. WISE, NASA's infrared telescope, snapped this amazing image of Zeta Ophiuchi and its "bow shock." NASA experts explain what's going on here: As the star tears through space, its powerful winds push gas and dust out of its way and into what is called a bow shock. The material in the bow shock is so compressed that it glows with infrared light that WISE can see. The effect is similar to what happens when a boat speeds through water, pushing a wave in front of it. This bow shock is completely hidden in visible light. Infrared images like this one from WISE are therefore important for shedding new light on the region.

dat mag je zelf opzoeken , maar ik post het er voortaan wel even bij.
