On July 5th the SOlar and Heliospheric Observatory (SOHO) captured video of a comet, known as a sungrazer, in route to collide with our star. SOHO is equipped with an occluding coronograph that blocks direct sunlight and reveals the corona, but also prevents direct study of the terminal impact of sungrazers. But on July 6th, with the help of the Solar Dynamics Observatory (SDO), astronomers were able to observe the comet (slyt) streaking in front of the surface of the sun for the first time in history. It likely disintegrated before impact due to extreme heat and radiation.

This  may just be the most peaceful, beautiful 5-1/2 minutes of your entire day: An audio slideshow look at some of the winning images, guided by one of the judges, of the Royal Observatory in Greenwich's 2010 Astronomy Photographer of the Year competition. Interested in "giving it a go"? Here are some guides to photographing different aspects of the night sky.

"Workmanlike" astronomy: The Vatican Observatory, among the oldest astronomical centers in the world, brings a team of Jesuits to the papal summer residence. Its scientists play a large part in the church's efforts to reconcile faith with reason. [Previously.] [more inside]

The Sphinx Observatory atop the Jungfraujoch in the Swiss alps is one of the most amazing man-made objects I've ever seen. A UNESCO world-heritage site, it holds the distinction of being the highest (in altitude) structure in all of Europe. Approachable by a train that runs inside the mountain (via a tunnel dug between 1896 & 1926 at the cost of a small fortune, not to mention many lives), the Observatory rests atop a glacier which has been hollowed out to feature a year round gallery of never-melting ice scultptures (glacial ice is spectacularly pretty), and an elevator up to the research station.

The GTC (Great Telescope Canaries) sees first light today. Apart from the sheer size (10.4 m) of its mirror and from the science it will deliver, the GTC is remarkable by its location at the Roque de los Muchachos Observatory 2426 m high at the rim of the Caldera de Taburiente in the island of La Palma. La Palma is also, for a number of reasons, also interesting for geologists. In that regard, it made headlines a couple of years back due to a paper about the risk of a collapse of the island which could cause a devastating tsunami. Oh, and it's also a really nice place for a holiday.

The Super-K is a neutrino observatory in Japan; it is 1000 meters underground, contains a lake of 50,000 tons of pure water & every inch of the the 41 meter high walls are lined with over 11,000 photomultiplier tubes. It is also one of the most amazing man made objects I've ever seen images of. Super high res photos available here. More photos of the construction & recent restoration. Via.

Have you ever wondered what a solar eclipse would look like from space? The STEREO (Solar TErrestrial RElations Observatory) has just sent back its view (awe-inspiring video included). It has also sent back some gorgeous pictures of our sun (and the McNaught Comet). For more media, check out the other galleries (including some 3D images). For more about the project, see NASA's STEREO homepage. Be sure to also stop by the Johns Hopkins University STEREO Page, where you can download a mission guide (pdf), view animations, watch a video of the launch, or even make your own papercraft STEREO model (pdf). You can also learn more in six minute segments with their series of short educational videos.

The Thirteen Towers of Chankillo in Peru may be the Western Hemisphere's oldest known full-service solar observatory, showing evidence of early, sophisticated Sun cults, according to archaeoastronomy professor Clive Ruggles. The 2,300-year-old complex featured 13 towers running north to south along a ridge and spread across 980 feet to form a toothed horizon that spans the solar arc. Last year, another ancient observatory was discovered in Peru by Robert Benfer. The Temple of the Fox is 4,200 years old, making it 1,900 years older than the Chankillo site, but wasn't a complete calendar.

NASA's Chandra X-Ray Observatory recently detected [reg required] the largest explosion ever detected in the universe: an eruption releasing the energy of hundreds of millions of gamma ray bursts. Just to put it in perspective, a single GRB releases enough radiation to wipe out just about everything human beings would require for survival in a 1000 light year radius. (The Milky Way spans ~100,000 light years, while the United Federation of Planets spans about 8,000). Arthur C. Clarke has gone so far as suggesting that GRBs might be one of the reasons for Extra-Terrestrial silence: Gamma Ray Bursts are so large and inescapable, a single one would wipe out even an enormous galactic empire. Makes killer asteroids seem downright quaint.

Firefighters defend $120 million telescope. Obviously forest fires and telescopes (qtvr) don't mix.
