A team of astronomers using NASA’s Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto.
The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system.
“The moons form a series of neatly nested orbits, a bit like Russian dolls,” said team lead Mark Showalter of the SETI Institute in Mountain View, Calif.
The discovery increases the number of known moons orbiting Pluto to five.
The Pluto team is intrigued that such a small planet can have such a complex collection of satellites. The new discovery provides additional clues for unraveling how the Pluto system formed and evolved. The favored theory is that all the moons are relics of a collision between Pluto and another large Kuiper belt object billions of years ago.
The new detection will help scientists navigate NASA’s New Horizons spacecraft through the Pluto system in 2015, when it makes an historic and long-awaited high-speed flyby of the distant world.
Verizon already has 100Gbps (gigabit-per-second) connections over its optical core networks across continents. Now the carrier is bringing that speed to its metro networks, which enterprises tap into for high-speed data connections. The metro networks so far have been limited to 10Gbps or 40Gbps.
Though the carrier doesn’t expect many customers to start ordering 100Gbps connections soon, it is preparing for the future.
Verizon’s 100-gigabit U.S. backbone technology forms the basis of a high-speed, low-latency network for financial trades that was inaugurated between Chicago and New York last month. It can complete a stock trade in as little as 14.5 milliseconds, according to the carrier.
Verizon said it has begun to use the same general architecture for high-speed land-based networks that it already uses for its connections across oceans. That architecture, based on a mesh of cables, gives traffic across its core network more alternate routes to take if one cable breaks. This is a step up from a ring architecture, in which the network recovers by sending bits the other way around the ring if one spot on it is damaged.
Verizon already has mesh networks across the Pacific and across the Atlantic, each with eight alternate paths.
Just a few days ago the Academy Awards for Scientific and Technical Achievements were announced. The 8 awards go to a wide range of professionals in areas such as computer software, high-speed cameras, aerial cameras, and laser film preservation.
In many ways these descriptions are beyond our understanding, but they do, at the very least, bring into your mind the constant innovation in the film business.
These awards will be handed out on February 11, 2012, with the main awards show going on two weeks later.
Invention and integration of micro-voxels in the Mantra software. This work allowed, for the first time, unified and efficient rendering of volumetric effects such as smoke and clouds, together with other computer graphics objects, in a micro-polygon imaging pipeline.

Phantom High-Speed Cameras
Design and engineering of the Phantom family of high-speed cameras for motion picture production. The Phantom family of high-speed digital cameras, including the Phantom Flex and HD Gold, provide imagery at speeds and efficacy surpassing photochemical technology, while seamlessly intercutting with conventional film production.

I love this video from Japan, one of the most popular of 2011. It shows the first ride of a new high-speed rail train. All of these people make faces, dance, moon, and wear special costumes as it goes by.
I wonder if this is how Californians will act when the LA – SF train is built?
