Zodiacal Light Vs. Milky Way

Posted by Nexus – 23/03/2010

[via APOD]

Ghostly Zodiacal light, featured near the center of this remarkable panorama, is produced as sunlight is scattered by dust in the Solar System’s ecliptic plane.

In the weeks surrounding the March equinox (today at 1732 UT) Zodiacal light is more prominent after sunset in the northern hemisphere, and before sunrise in the south, when the ecliptic makes a steep angle with the horizon.

In the picture, the narrow triangle of Zodiacal light extends above the western horizon and seems to end at the lovely Pleiades star cluster. Arcing above the Pleiades are stars and nebulae along the plane of our Milky Way Galaxy.

The Nearby Milky Way in Cold Dust

What shapes the remarkable dust tapestry of the nearby Milky Way Galaxy? No one knows for sure. The intricate structures, shown above, were resolved in new detail recently in a wide region of the sky imaged in far infrared light by the European Space Agency’s Planck satellite.

The above image is a digital fusion of three infrared colors: two taken at high resolution by Planck, while the other is an older image taken by the now defunct IRAS satellite. At these colors, the sky is dominated by the faint glow of very cold gas within only 500 light years of Earth.

An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in the constellation of Orion.

The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. Of the two reflection nebulas pictured above, the more famous nebula is M78, in the image center, while NGC 2071 can be seen to its lower left.

Mars Over the Allalinhorn

What’s that bright object in the sky? A common question with answers that vary by time and season, the quick answer just after sunset in middle of last month, from the northern hemisphere, was Mars.

The above picturesque panorama, taken during a ski trip from the Alps in Switzerland, shows not only Mars, but much more. Pine trees line the foreground, while numerous slopes leading up to the snow covered Allalinhorn mountain are visible in the distance.

Animation of Giant Iceberg Collision as Seen From Space

Posted by Nexus – 07/03/2010

[via wired.com]

The collision in early February of the 60-mile-long B-9B iceberg with the protruding tongue of the Mertz Glacier in East Antarctica is captured here in a series of satellite radar images.

The crash created a second massive iceberg nearly 50 miles long and 25 miles wide, named C-28. The name means that it’s the 28th glacier since 1976 that has broken off from the quadrant of Antarctica that faces Australia.

Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices.

This sharp, colorful image reveals the galaxy’s bulging central core cut by obscuring dust lanes that lace NGC 4565′s thin galactic plane. An assortment of other galaxies is included in the pretty field of view. Neighboring galaxy NGC 4562 is at the upper right. NGC 4565 itself lies about 40 million light-years distant, spanning some 100,000 light-years.

Street View goes user-generated

Posted by Nexus – 02/03/2010

[via bit-tech.net]

Google has launched its first user-generated version of Street View, which maps geolocated images in a 3D space and allows for virtual walk-throughs with impressive imagery.

As reported over on GigaOM,the new layer allows users to upload two-dimensional photographs and place them within a three-dimensional space – creating a 3D panorama of the area with far higher resolution and quality than that available from the standard Street View service.

The idea isn’t new: back in 2006 Microsoft unveiled its Silverlight-based 2D-to-3D photo manipulation system Photosynth, which works in much the same way: taking images uploaded by individuals and placing them within a collaborative space to create a fully immersive – if slightly herky-jerky – 3D panorama.

A jewel of the southern sky, the Great Carina Nebula, aka NGC 3372, spans over 300 light-years.

Near the upper right of this expansive skyscape, it is much larger than the more northerly Orion Nebula. In fact, the Carina Nebula is one of our galaxy’s largest star-forming regions and home to young, extremely massive stars, including the still enigmatic variable Eta Carinae, a star with well over 100 times the mass of the Sun.
