Large, distant comets more common than previously thought

more »
There are about seven times more long-period comets measuring at least 1 kilometer across than previously predicted, suggests new research. The researchers also found that long-period comets are, on average, nearly twice as large as 'Jupiter family' comets, whose orbits are shaped by Jupiter's gravity and have periods of less than 20 years.

Int-Ball Drone Activated on the Space Station

more »

What if you were followed around by a cute floating ball that kept taking your picture? Then you might be an astronaut on today's International Space Station (ISS). Designed by the Japan Aerospace Exploration Agency (JAXA), the JEM Internal Ball Camera -- informally "Int-Ball" -- is a bit larger than a softball, can float and maneuver by itself but also be controlled remotely, can take high resolution images and videos, and is not related to Hello Kitty. Int-Ball was delivered to the ISS in early June and is designed to allow ground-control to increase the monitoring of ISS equipment and activities while decreasing time demands on human astronauts. Int-Ball moves by turning on small internal fans and sees with a camera located between its two dark eyes.
