Final liftoff for space shuttle Atlantis
U. COLORADO (US)—The launch today from Kennedy Space Center is expected to be the last one for space shuttle Atlantis, marking the end of a career that includes 32 space missions—covering more than 115 million miles. (more…)

Einstein validated on cosmic scale
PRINCETON / UC BERKELEY (US)—An analysis of more than 70,000 galaxies demonstrates that the universe—at least up to a distance of 3.5 billion light years from Earth—plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity. (more…)

Caterpillars ‘lost’ in space without gravity
U. KANSAS (US)—A recent trip into low-Earth orbit has shown just how much monarch butterflies depend on gravity. (more…)

NASA launching tools to forecast solar activity
U. COLORADO (US)—An instrument package set for launch by NASA on Feb. 10 is expected to give scientists a better understanding of the sun’s impact on space weather. (more…)

Simulated galaxies resemble real ones
WASHINGTON (US)—Using millions of hours on supercomputers, researchers have run simulations of galaxy formation and produced dwarf galaxies very much like those observed today by satellites and large telescopes around the world. (more…)

Early galaxies as never seen before
U. COLORADO (US)—The Herschel Space Observatory has provided one of the most detailed views yet of space up to 12 billion years back in time. The images reveal thousands of newly discovered galaxies in their early stages of formation, says astrophysicist Jason Glenn. (more…)

Putting a lander on Earth’s ‘evil twin’
U. COLORADO (US)—What would it take to land a spacecraft on Venus? NASA has asked a research team at the University of Colorado at Boulder to help answer that question with a detailed, one-year concept study to examine the planet’s surface, climate, and atmosphere—and to predict its ultimate fate in the solar system. (more…)

Space Station to host hatching butterflies
U. COLORADO (US)—When NASA’s space shuttle Atlantis launches for the International Space Station on Nov. 16 it will carry a butterfly experiment that will be monitored by thousands of K-12 students across the nation. The public, too, can view images and keep tabs on the project at http://bioedonline.org and www.monarchwatch.org/space. (more…)

Race ends in dead heat; Einstein wins
STANFORD (US)—Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA’s orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish may stoke the fires of debate among physicists over Einstein’s special theory of relativity because one of the photons possessed a million times more energy than the other.

Playing hide and seek with exoplanets
U. COLORADO (US)—A precise “laser ruler” is being developed to look for Earth-like planets around other stars. The device will measure tiny changes in infrared light caused by the gravitational wobble of small, cool stars as they are tugged back and forth by their rocky planets. (more…)

Cassini reshapes view of solar system
JOHNS HOPKINS (US)—It turns out that the solar system may look more like a basketball than a comet. Images from one of the sensors on NASA’s Cassini spacecraft suggest that the heliosphere—the region of our sun’s influence—may not have the comet-like shape predicted by existing models. (more…)

Model suggests it’s raining rocks on exoplanet
WASHINGTON-ST. LOUIS (US)—An exoplanet discovered last February by the COROT space telescope is close enough to its star that its “day-face” is hot enough to melt rock. Theoretical models suggest the planet has a gaseous-rock atmosphere and boiling oceans on its surface. (more…)

Messenger makes final Mercury flyby
U. COLORADO (US)—NASA’s Messenger spacecraft will zip by Mercury for the third and final time today, September 29, cruising within 142 miles of the planet’s surface at more than 100,000 mph. Messenger will take high-resolution color images of the surface terrain before making a clever gravity-assist maneuver that will steer it into orbit around the rocky planet beginning in March 2011.

Crystals to grow in low gravity on Space Station
IOWA STATE (US)—An experiment to study crystal growth patterns in a microgravity environment that is on its way to the International Space Station may have important implications for developing new materials. (more…)

Twinkle, twinkle: Early stars came in pairs
This computer-simulated image shows the formation of two high density regions (yellow) in the early universe. The cores are expected to evolve into a binary—or ‘twin’—star system. (Courtesy: Ralf Kaehler, Matthew Turk, and Tom Abel)

Photos capture debris from galactic collisions
Above, a deep optical image of Arp 220, located 250 million light years away in the constellation Serpens. New tidal debris is seen as the southern extension. Below, a new image of the Antennae galaxies in the constellation Corvus, 65 million light years from Earth, shows new tidal debris at the northern tip.
