k = 0.01720209895 A3/2S-1/2D-1. In 1939 the International Astronomical Union adopted the above value as a defining constant in astronomy. The value of the astronomical unit is derived from it, and is no longer defined by the actual orbit of the Earth. In modern ephemerides, the mean orbital axis of...
Title: A Unique Star in the Outer Halo of the Milky Way Authors: David K. Lai, Constance M. Rockosi, Michael Bolte, Jennifer A. Johnson, Timothy C. Beers, Young Sun Lee, Carlos Allende Prieto, Brian Yanny As part of a program to measure abundance ratios in stars beyond 15 kpc from the Galactic center,...
The Enriched Xenon Observatory is an experiment in particle physics aiming to detect "neutrino-less double beta decay" using large amounts of xenon isotopically enriched in the isotope 136. A 200-kg detector using liquid Xe is currently being installed at the Waste Isolation Pilot P...
Expedition 313 - New Jersey Shallow Shelf The New Jersey Shallow Shelf Expedition will be implemented in 2009. The offshore phase of the expedition will start in May, further details will be announced as soon as possible. This IODP expedition receives additional financial support from the Intern...
For the past 24 years, once a month, 300 pairs of eyes in the far-flung town of Vangani turn star-struck. It happens on Saturdays around new moon nights. As the sun sets, registration queues line up at counters set up in the grounds of a private bungalow. Mats are spread on the ground, and families settl...
A Mauna Kea telescope will be taken down from its near-summit home within the next decade, ending more than 30 years of astronomical observations. Read more The Caltech Submillimeter Observatory (CSO) is a cutting-edge facilit...
"The Lady of the Lake" is such a romantic name that mud boots would spoil the Arthurian image, but it can't be helped. In search of such mystery and beauty, I travelled to Lake Drummond in Suffolk, 30 minutes west of my house, and also to Mountain Lake near Blacksburg, some five hours farther...
Satellites and spent rocket stages could soon deploy "sails" to guide them back to Earth much faster than they would otherwise fall out of the sky. With space becoming ever more crowded, there is a need to remove redundant objects that could pose a collision threat to operational mission...
What happened in the first trillionth of a trillionth of a trillionth of a second after the Big Bang? Super-sensitive microwave detectors, built at the National Institute of Standards and Technology (NIST), may soon help scientists find out. The new sensors, described today at the American Physi...

In its first set of biological experiments, the Indian Space Research Organisation (ISRO) will send bacteria cells into space - and bring them back - in the second Space Capsule Recovery Experiment (SRE-2) scheduled for launch this year-end. Two life science experiments, using E.coli and photos...
ISRO developed new satellite RISAT After the success of Chandrayaan- 1, Indian Space Research Organisation (ISRO ) has developed a new satellite, Radar Imaging Satellite (RISAT) that can capture images through the clouds which will enable space-based applications in such scenarios as managin...
