Japanese research develops holograms you can touch (via Switched)
According to the NTDTV report researchers at Japan’s Tokyo University have managed to concoct holograms that not only react to touch, but that also create the sensation of touch, itself. Apparently, and not surprisingly, an integral part of the system is Nintendo’s Wiimote technology, which senses user input.
Ultrasonic waves are what create the sensory impression.
The Main Sequence
A Hertzsprung-Russell diagram plots the actual brightness (or absolute magnitude) of a star against its color index (represented as B-V). The main sequence is visible as a prominent diagonal band that runs from the upper left to the lower right. This plot shows 22,000 stars from the Hipparcos Catalogue together with 1,000 low-luminosity stars (red and white dwarfs) from the Gliese Catalogue of Nearby Stars. /via Wikipedia
Enceladus, one of Saturn’s 62 known moons, spews plumes of water ice.
At least four distinct plumes of water ice spew out from the south polar region of Saturn’s moon Enceladus in this dramatically illuminated image.
Light reflected off Saturn is illuminating the surface of the moon while the sun, almost directly behind Enceladus, is backlighting the plumes. See PIA11688 to learn more about Enceladus and its plumes.
This view looks toward the Saturn-facing side of Enceladus (504 kilometers, or 313 miles across). North is up.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 25, 2009. The view was obtained at a distance of approximately 617,000 kilometers (383,000 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 174 degrees. Image scale is 4 kilometers (2 miles) per pixel.
