From Astronomy Picture Of The Day; April 3, 2013: Comet PANSTARRS and the Andromeda Galaxy Pavel Smilyk Currently, comet PANSTARRS is passing nearly in front of the galaxy Andromeda. Coincidentally, both comet and galaxy appear now to be just about the same angular size. In physical size, even though Comet PANSTARRS is currently the largest object in the Solar System with a tail spanning about 15 times the diameter of the Sun, it is still about 70 billion times smaller than the Andromeda galaxy (M31). The above image was taken a few days ago near Syktyvkar, Russia. As C/2011 L4 (PANSTARRS) on the lower left recedes from the Sun and dims, it is returning to the northerly direction whence it came. When the comet will return is currently unknown, although humans may have merged with computers by then

Comet PANSTARRS and the Andromeda Galaxy 
Pavel Smilyk

Currently, comet PANSTARRS is passing nearly in front of the galaxy Andromeda. Coincidentally, both comet and galaxy appear now to be just about the same angular size. In physical size, even though Comet PANSTARRS is currently the largest object in the Solar System with a tail spanning about 15 times the diameter of the Sun, it is still about 70 billion times smaller than the Andromeda galaxy (M31). The above image was taken a few days ago near Syktyvkar, Russia. As C/2011 L4 (PANSTARRS) on the lower left recedes from the Sun and dims, it is returning to the northerly direction whence it came.

astronomy-picture-of-the-day: What’s lighting up nebula IRAS 05437+2502? No one is sure. Particularly enigmatic is the bright upside-down V that defines the upper edge of this floating mountain of interstellar dust, visible near the image center. In general, this ghost-like nebula involves a small star forming region filled with dark dust that was first noted in images taken by the IRAS satellite in infrared light in 1983. Shown above is a spectacular, recently released image from the Hubble Space Telescope that, although showing many new details, has not uncovered a clear cause of the bright sharp arc. One hypothesis holds that the glowing arc was created by a massive star that somehow attained a high velocity and has now left the nebula. Small, faint IRAS 05437+2502 spans only 1/18th of a full moon toward the constellation of the Bull (Taurus).

Note that they are compressed and split up due to Tumblr’s size restrictions, and the divided animations may not line up properly at first… just give them time to load and perhaps refresh your browser—or better yet, visit Metsavianio’s blog for the animations in all their (7MB of) glory!] via PetaPixel: Parallax 3D images use two photos captured from slightly different vantage point to create the appearance of depth. In astrophotography, however, the distance between human cameras and distance objects are so great that real parallax generally cannot be achieved. Finnish astrophotographer J-P Metsavainio has developed a brilliant experimental technique that overcomes this (kinda): he converts astrophotographs into 3D volumetric models, and then uses those models to create dazzling 3D animations of nebulae. Metsavainio tells us that his technique is a mixture of science and art. He first gathers specific information about the nebula in his photo prior to doing the 3D conversion. More important is the distance information of known stars, which allows him to place them at correct relative distances from one another in his resulting model. Metsavainio on how the 3D conversion is done: After the first step [gathering the info about the stars], the nebula layer of the image get splitted to an elemets by it’s structure. Then a 3d-mesh is made by the brightness of the nebula. This can be done since the gas in the nebula emits a light of it own and the thickness of the nebula can be estimated by the amount of light. Then I split the star image to a separate layers by the star brightness and the color index. If there are stars with a known distance, like ones coursing the emission of the nebulosity, I separate them to a different layers, all the steps are done “semi automatic”. At the final step all the image information, nebula and stars, are projected to complex 3D-suffaces and some tweaking can be done three dimensionally. Rest of the work is traditional animation work.
