Satellite-hunters find four new moons of the planet Saturn

An international team of eight "satellite hunters," astronomers who pluck tiny specks of light out of the distant solar system, has discovered four new outer moons of Saturn orbiting at least 15 million kilometers from the surface of the giant planet.

Insect flight obeys aerodynamic rules, Cornell physicist proves

The computer-modeling accomplishment - which is expected to aid the future design of tiny insect-like flying machines and should dispel the longstanding myth that "bumblebees cannot fly.

'Great show-off' black hole -microquasar GRS 1915+105 - is producing massive shock waves, Cornell astronomer reports

ATLANTA -- Something really shocking is going on in a microquasar, or black hole, dubbed "Old Faithful," some 40,000 light years from Earth. It seems to be behaving like a giant particle collider, with massive shock waves generating eruptions every 45 to 90 minutes. This is the second time that Old Faithful, the first known microquasar in our galaxy, the Milky Way, has been observed to be acting strangely. Two years ago astronomers presented evidence, from X-ray and infrared observations, that the microquasar is sending out jets of hot gas at close to regular half-hour intervals.

It's the 25th anniversary of Earth's first attempt to phone E.T.

Twenty-five years ago next week, humanity sent its first and only deliberate radio message to extraterrestrials. Nobody has called back yet, but that's OK -- we weren't really expecting an answer. (November 12, 1999)

Gold finds our deep hot biosphere teeming with life - and controversy

In a new book, The Deep Hot Biosphere, Cornell professor emeritus of astronomy Thomas Gold argues that subterranean bacteria started the whole evolutionary process, and that there's no looming energy shortage because oil reserves are far greater than predicted.

Galileo finds Jupiter's rings formed by dust blasted off small moons

Jupiter's intricate, swirling ring system is formed by dust kicked up as interplanetary meteoroids smash into the giant planet's four, small inner moons, according to scientists studying data from NASA's Galileo spacecraft. Images sent by Galileo also reveal that the outermost ring is actually two rings, one embedded within the other.

It might wobble and stagger, but Cornell's headless robot is providing insights into how humans walk

It doesn't have a brain or a heart, and its walk is a little like the scarecrow's, but a little headless, armless, trunkless two-legged robot, developed at Cornell University, can walk, wobble, hobble, limp, stride and stagger. But it can't stand still in any position without falling over. (April 7, 1998)

Smallest guitar, about the size of a human blood cell, illustrates new technology for nano-sized electromechanical devices

The world's smallest guitar -- carved out of crystalline silicon and no larger than a single cell -- has been made at Cornell University to demonstrate a new technology that could have a variety of uses in fiber optics, displays, sensors and electronics.
