Astronomers have worried about the impact that asteroids could have on Earth ever since a theory was proposed in the 1980s that a giant asteroid likely caused the extinction of the dinosaurs 65 millio...
NASA's Wide-field Infrared Survey Explorer, or WISE, has captured its first look at the starry sky that it will soon begin surveying in infrared light.Launched on Dec. 14, WISE will scan the entire s...
NASA's Kepler space telescope, designed to find Earth-size planets in the habitable zone of sun-like stars, has discovered its first five new exoplanets, or planets beyond our solar system.Kepler's hi...
A moon rock collected during the historic Apollo 11 mission more than 40 years ago will be heading back to space and a new home aboard the International Space Station, sharing quarters with a piece of...
During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. It captured more than one thousand discrete sources of...
NASA's Spitzer Space Telescope has discovered an enormous ring around Saturn -- by far the largest of the giant planet's many rings.The new belt lies at the far reaches of the Saturnian system, with ...
Anyone who has watched videos of the Apollo astronauts moving across the surface of the moon has noticed the unusual loping gait they sometimes adopted and their slow, almost graceful, movements. Now ...
Analysis of Hubble Space Telescope Fine Guidance Sensor Data in TRANS Mode:An Overview。
Cosmological Surveys with the Spitzer Space Telescope
Spectroscopy, photometry and micro-arcsec astrometry Of binaries with the Gaia space mission and with the rave Experiment。
Planetary nebulae results from the infrared space observatory。
The phase-space structure of CDM halos and dark-matter direct detection experiments。
Spectroscopy of stellar Jets, outflows, and Young stellar objects with the infrared space observatory。
Necessary conditions are discussed for the possible generation of large solitary acoustic modes in plasmas with one or more ion species which are hotter than some or all of the electron species. The a...
We compute the density redshift-space power spectrum in the presence of tangled magnetic fields and compare it with existing observations. Our analysis shows that if these magnetic fields originated...
