U of M to help NASA 'follow the sun' — in stereo
Like geologists poring over seismograph records to identify the telltale signature of an imminent earthquake, University of Minnesota researchers are poised to probe the sun for a tipoff that a huge eruption of its corona is brewing.   view more (2006-10-19)

First detailed pictures of asteroid reveal bizarre system
The first detailed images of a binary asteroid system reveal a bizarre world where the highest points on the surface are actually the lowest, and the two asteroids dance in each other's gravitational pull.   view more (2006-10-13)

The day LISA Pathfinder hung in the balance
At the core of ESA's LISA Pathfinder mission sit two small hearts. Each is a cube, just 5 centimetres across. Together they will allow LISA Pathfinder to lay the foundations for future space-based measurements that investigate the very core of Einstein's General Relativity.   view more (2006-10-12)

Flies in a spider's web: Galaxy caught in the making
In nature spiders earn our respect by constructing fascinating, well-organised webs in all shapes and sizes. But the beauty masks a cruel, fatal trap. Analogously, the NASA/ESA Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth (at a redshift of 2.2) that is... view more (2006-10-12)

Ultrafast star escapes black hole
Galactic nuclei are the cores of galaxies, groups of thousands to millions of stars that are held together by gravity. As stars in the nucleus are so close together, interactions readily occur.   view more (2006-10-05)

Robot wheelchair may give patients more independence
Engineers at the National Institute of Standards and Technology (NIST) are developing a robotic system that may offer wheelchair-dependent people independent, powered mobility and the ability, depending on patient status, to move to and from beds, chairs and toilets without assistance.   view more (2006-10-02)

Greenland ice sheet still losing mass, says new University of Colorado study
Data gathered by a pair of NASA satellites orbiting Earth show Greenland continued to lose ice mass at a significant rate through April 2006, and that the rate of loss is accelerating, according to a new University of Colorado at Boulder study.   view more (2006-09-21)

Scientists snap images of first brown dwarf in planetary system
Scientists using NASA's Spitzer Space Telescope have discovered and directly imaged a small brown dwarf star, 50 times the mass of Jupiter, orbiting with a planet around a Sun-like star.   view more (2006-09-19)

Paramecia Adapt Their Swimming to Changing Gravitational Force
For many single-celled organisms living in water, the force is always against them. The classic example is the slipper-shaped paramecium, which consistently swims harder going up than going down, just to keep from sinking.   view more (2006-09-19)

General relativity survives gruelling pulsar test — Einstein at least 99.95 percent right
An international research team led by Prof. Michael Kramer of the University of Manchester's Jodrell Bank Observatory, UK, has used three years of observations of the "double pulsar", a unique pair of natural stellar clocks which they discovered in 2003, to prove that Einstein's theory of... view more (2006-09-14)

Spread of plant diseases by insects can be described by equations that model interplanetary gravity
Researchers from Penn State University and the University of Virginia show that the spread of diseases by insects can be described by equations similar to those that describe the force of gravity between planetary objects.   view more (2006-09-05)

Impact landing ends SMART-1 mission to the Moon
ESA PR 31-2006. Early this morning, a small flash illuminated the surface of the Moon as the European Space Agency's SMART-1 spacecraft impacted onto the lunar soil, in the 'Lake of Excellence' region.   view more (2006-09-05)

Cassiopeia A - The colorful aftermath of a violent stellar death
A new image taken with the NASA/ESA Hubble Space Telescope provides a detailed look at the tattered remains of a supernova explosion known as Cassiopeia A (Cas A). It is the youngest known remnant from a supernova explosion in the Milky Way.   view more (2006-08-30)

Low altitude flying with coarse maps - determining the time of SMART-1 impact
What exactly determines the time of the SMART-1 impact? What causes the uncertainty in the impact time?   view more (2006-08-28)

NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter.   view more (2006-08-22)

The IAU draft definition of 'planet' and 'plutons'
The world's astronomers, under the auspices of the International Astronomical Union (IAU), have concluded two years of work defining the difference between "planets" and the smaller "solar system bodies" such as comets and asteroids.   view more (2006-08-16)

Fruit flies aboard space shuttle subjects of UCF, UC Davis study on immunity and space
Fruit flies aboard the Space Shuttle Discovery will help University of Central Florida and University of California, Davis, biologists learn more about how prolonged stays in space could affect human immune systems.   view more (2006-06-28)

U of M study examines kidney stone prevention in astronauts
As the space shuttle Discovery prepares to launch on July 1, researchers at the University of Minnesota have identified a way for astronauts to reduce their risk of developing kidney stones while in space.   view more (2006-06-28)

Big bang in Antarctica — killer crater found under ice
Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs — an impact that they believe caused the biggest mass extinction in Earth's history.   view more (2006-06-02)

Scientists predict how to detect a fourth dimension of space
Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity.   view more (2006-05-26)

Penn State Researchers Look Beyond the Birth of the Universe
According to Einstein's general theory of relativity, the Big Bang represents The Beginning, the grand event at which not only matter but space-time itself was born.   view more (2006-05-15)

Titan's seas are sand
Until a couple of years ago, scientists thought the dark equatorial regions of Titan might be liquid oceans.   view more (2006-05-05)

MIT: Mini satellites rocketing to space station
A Russian rocket launched Monday, April 24, is carrying the first of three small, spherical satellites developed at MIT to the International Space Station - a major step toward building space-based robotic telescopes and other systems.   view more (2006-04-27)

Magellanic gemstones in the southern sky
Hubble has captured the most detailed images to date of the open star clusters NGC 265 and NGC 290 in the Small Magellanic Cloud-two sparkling sets of gemstones in the southern sky.   view more (2006-04-18)

Study finds two supermassive black holes spiraling toward collision
A pair of supermassive black holes in the distant universe are intertwined and spiraling toward a merger that will create a single super-supermassive black hole capable of swallowing billions of stars.   view more (2006-04-06)
