Study: 3-D movies aren't that special

Science Focus

original post »


In theory, three-dimensional video heightens the emotional impact of a movie scene — imagine if that guy from My Bloody Valentine appeared to be swinging his pickaxe straight at you, or if The Polar Express swooped out of the screen and just narrowly avoided running over your popcorn.

Pretty exciting, huh? Perhaps, but psychologists — who are a bit more even-tempered about the latest technology and a bit less interested in your wallet, compared with movie producers — say otherwise in a recent study.

Though movie makers might well take note, Daniel Bride, Sheila Crowell, and...

MIT researchers take cheetah robot out for a run without a leash

Science Focus

original post »

MIT researchers have released a video of a robot they're calling "cheetah" making its way across campus. An earlier robot that was also called cheetah was part of a DARPA/Boston Dynamics (now owned by Google) collaboration that was notable for its speed. The MIT version is notable for ditching the tethers that supplied power to it—it goes for runs using on-board battery power and control logic.

Cheetah is only able to move at up to 10 mph, but its developers expect that they'll be able to get it to eventually travel at up to 30 miles an hour. For now, cheetah's biggest accomplishment is being able to move without any wires, which are normally used to supply power, and in some cases command-and-control, to more sophisticated robots.

The MIT group has also been working on the mechanics of the robot's stride, trying to have it exert more force each time it strikes the ground. The result is that it's been able to move across less rigid surfaces, like grass, which is why it's able to be taken out onto the MIT campus. Additionally, they've developed a routine that allows the robot to take a hop, which will let it bound over obstacles.

Initialled Dumbbell Nebula Constellation Vulpecula Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: awesome astronomy images, inspirational, dmbblneb, vulpecula constellation, intense ultraviolet radiation, european southern observatory, messier 27 ngc 6853, heavens, monograms, initialled, eso, vista, initials, monogrammed, monogram

Galaxies, Stars and Nebulae series A great photo from deep space featuring the Dumbbell Nebula - also known as Messier 27 or NGC 6853. It's a typical planetary nebula and is located in the constellation Vulpecula (The Fox).

The distance is rather uncertain, but is believed to be around 1,200 light-years. It was first described by the French astronomer and comet hunter Charles Messier who found it in 1764 and included it as no. 27 in his famous list of extended sky objects.

Despite its class, the Dumbbell Nebula has nothing to do with planets. It consists of very rarefied gas that has been ejected from the hot central star (well visible on this photo), now in one of the last evolutionary stages. The gas atoms in the nebula are excited (heated) by the intense ultraviolet radiation from this star and emit strongly at specific wavelengths.

This image is the beautiful by-product of a technical test of some FORS1 narrow-band optical interference filters. They only allow light in a small wavelength range to pass and are used to isolate emissions from particular atoms and ions.

In this three-colour composite, a short exposure was first made through a wide-band filter registering blue light from the nebula. It was then combined with exposures through two interference filters in the light of double-ionized oxygen atoms and atomic hydrogen. They were colour-coded as “blue”, “green” and “red”, respectively, and then combined to produce this picture that shows the structure of the nebula in “approximately true” colours.

A Launch and a Landing

more »
Taken from an Atlantic beach, Cape Canaveral, planet Earth, four identically framed digital images are combined in this night skyscape. Slightly shifted short star trails dot the sky, but the exposure times were adjusted to follow the flight of a Falcon 9 rocket. The September 21 launch delivered a Dragon X capsule filled with supplies to the International Space Station. Above the bright flare seen just after launch, the rocket's first stage firing trails upward from the left. After separation, the second stage burn begins near center with the vehicle climbing toward low Earth orbit. At the horizon, the flare near center records the re-ignition and controlled descent of the Falcon 9's first stage to a soft splashdown off the coast.

Glowing Stellar Nurseries RCW120 Room Stickers

Here's a great wall decal featuring a beautiful image from deep space


tagged with: nebulae, gstlnrsr, breathtaking astronomy images, star nurseries, star clusters, ionised gas clouds, galaxies and stars, starfield rcw120, european southern observatory, star forming regions, eso, vista

Galaxies, Stars and Nebulae series A fantastic astronomy picture featuring a colour composite image of RCW120.

It reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps where new stars are then formed.

The 870-micron submillimetre-wavelength data were taken with the LABOCA camera on the 12-m Atacama Pathfinder Experiment (APEX) telescope. Here, the submillimetre emission is shown as the blue clouds surrounding the reddish glow of the ionised gas (shown with data from the SuperCosmos H-alpha survey). The image also contains data from the Second Generation Digitized Sky Survey (I-band shown in blue, R-band shown in red).

NGC 602 bright stars Cover For The iPad Mini

Here's a great iPad case from Zazzle featuring a Hubble-related design. Maybe you'd like to see your name on it? Click to personalize and see what it's like!


tagged with: nasa, space, astronomy, shuttle, hubble, bright, star, starry, blue, nebula

NGC 602 is a young, bright open cluster of stars located in the Small Magellanic Cloud (SMC), a satellite galaxy to the Milky Way. Radiation and shock waves from the stars have pushed away much of the lighter surrounding gas and dust that compose the nebula known as N90, and this in turn has triggered new star formation in the ridges (or "elephant trunks") of the nebula.

Monogram - Eagle Nebula, Pillars of Creation Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: breathtaking astronomy images, eglneb, young stars clusters, star forming nebulae, messier 16 ngc 6611, pillars of creation, inspirational, eagle nebula, monograms, initialled, heavens, eso, european southern observatory, vista, initials, monogrammed, monogram

Galaxies, Stars and Nebulae series A breathtaking outer space picture showing a spectacular three-colour composite mosaic image of the Eagle Nebula (Messier 16, or NGC 6611). It's based on images obtained with the Wide-Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory.

At the centre, the so-called “Pillars of Creation” can be seen and this wide-field image shows not only the central pillars, but also several others in the same star-forming region, as well as a huge number of stars in front of, in, or behind the Eagle Nebula.

The cluster of bright stars to the upper right is NGC 6611, home to the massive and hot stars that illuminate the pillars. The “Spire” - another large pillar - is in the middle left of the image.

tagged with: nebulae, hubble chandra images, cats eye nebula, dying star, red giant evolution, outer space, galaxy stars, tcenebnch, deep space astronomy, eye of god, stellar evolution, nasa

Galaxies, Stars and Nebulae series A gorgeous design featuring a composite image of the Cat's Eye nebula from NASA's Chandra X-ray Observatory and the Hubble Space Telescope.
This famous nebula represents a phase of stellar evolution after a star like our Sun runs out of fuel. In this phase, a star becomes an expanding red giant and sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures.

Stellar Nursery R136 in the Tarantula Nebula iPad Cases

Here's a great iPad case from Zazzle featuring a Hubble-related design. Maybe you'd like to see your name on it? Click to personalize and see what it's like!


tagged with: astronomy, stellar nursery, massive stars, star cluster, tarantula nebula, hubble, galaxy stars, cosmological, 30 doradus nebula, hrbstslr dorneblmc, large magellanic cloud, r136, amazing hubble images, nebulae

Galaxies, Stars and Nebulae series Hundreds of brilliant blue stars wreathed by warm, glowing clouds in appear in this the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus (or Tarantula) Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way.
There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years. The image, taken in ultraviolet, visible, and red light by Hubble's Wide Field Camera 3, spans about 100 light-years.
The movement of the LMC around the Milky Way may have triggered the massive cluster's formation in several ways. The gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have compressed gas in the LMC. Also, the pressure resulting from the LMC plowing through the Milky Way's halo may have compressed gas in the satellite. The cluster is a rare, nearby example of the many super star clusters that formed in the distant, early universe, when star birth and galaxy interactions were more frequent.
The LMC is located 170,000 light-years away and is a member of the Local Group of Galaxies, which also includes the Milky Way. The Hubble observations were taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen.

Turning the Moon into a cosmic ray detector

more »

Scientists are to turn the Moon into a giant particle detector to help understand the origin of Ultra-High-Energy (UHE) cosmic rays -- the most energetic particles in the Universe. The origin of UHE cosmic rays is one of the great mysteries in astrophysics. Nobody knows where these extremely rare cosmic rays come from or how they get their enormous energies. Physicists detect them on Earth at a rate of less than one particle per square kilometer per century.
