- The impossible siblings
03-29-2007 · EurekAlert!
Combining precise observations obtained by ESO's Very Large Telescope with those gathered by a network of smaller telescopes, astronomers have described in unprecedented detail the double asteroid Antiope, which is shown to be a pair of rubble-pile chunks of material, of about the same size, whirling around one another in a perpetual pas de deux. The two components are egg-shaped despite their very small sizes.

- Amateurs and professionals combine observations to produce detailed picture of double asteroid
03-29-2007 · EurekAlert!
The main belt asteroid Antiope is among the few binary asteroids discovered in recent years, yet even through the Earth's largest telescopes it appears as merely two bright blobs orbiting one another. By harnessing the power of larger telescopes and the eagerness of amateurs with small instruments, UC Berkeley and Paris Observatory astronomers have constructed a detailed picture of the asteroid doublet: Two rubble piles twirling in a perpetual pas de deux.

- AKARI's view of Large Magellanic Cloud – star formation at work
11-01-2006 · European Space Agency (ESA)
The infrared surveyor AKARI, a Japan Aerospace Exploration Agency (JAXA) mission with ESA participation, is nearing the completion of its first scan of the entire sky. During this phase of the mission, it has supplied the largest wavelength coverage of the Large Magellanic Cloud to date, and provided fascinating new images of this galaxy.

- When washed in sunlight, asteroids hit the spin cycle, Cornell researchers find
03-07-2007 · EurekAlert!
The sun is a cosmic spinmeister. Using the highly sensitive radar telescope at the Cornell University-managed Arecibo Observatory in Puerto Rico and Goldstone antenna in California, Cornell astronomers have confirmed a theory that sunlight and the asteroid's shape determine how an asteroid's rotation evolves. Their research is reported today in Science Express, the online edition of the journal Science.

- Stardust comet dust resembles asteroid materials
01-24-2008 · EurekAlert!
Contrary to expectations for a small icy body, much of the comet dust returned by the Stardust mission formed very close to the young sun and was altered from the solar system's early materials.

- What light from yonder neutron breaks?
12-20-2006 · EurekAlert!
Researchers from the National Institute of Standards and Technology (NIST) and four universities have made the first experimental observation of rare particles of light emitted during the radioactive decay of the neutron, a key building block of matter. This work confirms theoretical predictions of this type of decay of the neutron and sets the stage for a new class of tests of basic theories in particle physics.
