Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

NASA plans to launch a new orbiter called Mars Reconnaissance Orbiter (MRO) on Aug. 10 as the next step in its ambitious Mars exploration program. MRO will return more data about the red planet than all previous Mars missions combined, according to the U.S. space agency. More than 40 University of Arizona researchers, family members and friends leave for NASA’s Kennedy Space Center in Florida next week to cheer the launch. The soon-to-fly orbiter payload includes UA’s High
VLT Enables Most Accurate Distance Measurement to Spiral Galaxy NGC 300
An international team of astronomers from Chile, Europe and North America [1] is announcing the most accurate distance yet measured to a galaxy beyond our Milky Way’s close neighbours. The distance was determined using the brightness variation of a type of stars known as “Cepheid variables”.
The team used the ISAAC near-infrared camera and spectrometer on ESO’s 8.2-m VLT Antu telescope to ob
Quantum dots programmed to glow in presence of enzyme activity
Researchers from Rice University’s Center for Biological and Environmental Nanotechnology (CBEN) have developed a “smart” beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases. Altered expression of particular proteases is a common hallmark of cancer, atherosclerosis, and many other diseases.

The latest close flyby of Saturn’s icy moon Enceladus by NASA’s Cassini spacecraft confirms that the moon has a significant, extended and dynamic atmosphere. The flyby, which took place on 14th July 2005, was Cassini’s lowest altitude flyby of any object to date, a mere 173 kilometres (108 miles) above the surface of Enceladus.
The 500 km diameter moon Enceladus is a very bright icy moon at a distance of 4 Saturn radii away from Saturn. It has long been associated with the formation of
