New Tide Gauge Measures Sea Level Change Using GPS Signals
2014-05-21 03:13:57

Robert Cumming, Chalmers University of Technology A new way of measuring sea level using satellite navigation system signals, for instance GPS, has been implemented by scientists at Chalmers University of Technology in Sweden. Sea level and its variation can easily be monitored using existing coastal GPS stations, the scientists have shown. ​Measuring sea level is an increasingly important part of climate research, and a rising mean sea level is one of the most tangible consequences...

[ Watch the Video: Zooming In On Active Galaxy NGC 1433 ] Brett Smith for redOrbit.com - Your Universe Online New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in the high-altitude Atacama Desert of Chile have revealed new details about the powerful molecular-gas jets that stream out of supermassive black holes, according to two new studies published on Wednesday in the journal Astronomy & Astrophysics. The two studies describe the unique behaviors and...

Taking Temperature Of Universe In Past Reveals Cooling Trend
2013-01-23 12:51:18

Lee Rannals for redOrbit.com — Your Universe Online Astronomers using the CSIRO radio telescope have discovered that the Universe's temperature has cooled down, which falls right in line with the Big Bang theory. An international team of astronomers from Sweden, France, Germany and Australia used the CSIRO Australia Telescope Compact Array near Narrabi to measure how warm the Universe was when it was half its current age. "This is the most precise measurement ever made of how...

Molecules of hydrogen peroxide have been found for the first time in interstellar space. The discovery gives clues about the chemical link between two molecules critical for life: water and oxygen. On Earth, hydrogen peroxide plays a key role in the chemistry of water and ozone in our planet's atmosphere, and is familiar for its use as a disinfectant or to bleach hair blonde. Now it has been detected in space by astronomers using the ESO-operated APEX telescope in Chile. An international team...

The Atacama Pathfinder Experiment (APEX) project celebrates the inauguration of its outstanding 12-m telescope, located on the 5100m high Chajnantor plateau in the Atacama Desert (Chile). The APEX telescope, designed to work at sub-millimetre wavelengths, in the 0.2 to 1.5 mm range, passed successfully its Science Verification phase in July, and since then is performing regular science observations. This new front-line facility provides access to the "Cold Universe" with unprecedented...
