Unravelling Coronal Mass Ejections from Our Solar System’s Origin

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…

Scientists Measure Extreme Bubble Temperatures, Surpassing Sun

Using a technique employed by astronomers to determine stellar surface temperatures, chemists at the University of Illinois at Urbana-Champaign have measured the temperature inside a single, acoustically driven collapsing bubble. Their results seem out of this world.

“When bubbles in a liquid get compressed, the insides get hot – very hot,” said Ken Suslick, the Marvin T. Schmidt Professor of Chemistry at Illinois and a researcher at the Beckman Institute for Advanced Science a

Quantum Computers: Easier to Build Than Expected

A full-scale quantum computer could produce reliable results even if its components performed no better than today’s best first-generation prototypes, according to a paper in the March 3 issue in the journal Nature* by a scientist at the Commerce Department’s National Institute of Standards and Technology (NIST).

In theory, such a quantum computer could be used to break commonly used encryption codes, to improve optimization of complex systems such as airline schedules, and to s

Chandra Explores Jupiter’s High-Voltage Auroras Insights

Scientists have obtained new insight into the unique power source for many of Jupiter’s auroras, the most spectacular and active auroras in the Solar System. Extended monitoring of the giant planet with NASA’s Chandra X-ray Observatory detected the presence of highly charged particles crashing into the atmosphere above its poles.

X-ray spectra measured by Chandra showed that the auroral activity was produced by ions of oxygen and other elements that were stripped of most

Astronomers Discover Most Distant Galaxy Cluster Yet

An international team of astronomers using the world’s largest X-ray and optical telescopes have spotted the most distant massive object ever detected, a cluster of galaxies 9 billion light years distant from Earth.

The cluster of galaxies is so far away that the light detected by the team is much older than the Earth itself. The galaxy cluster, if it is even still there, would be at least 11 billion years old now. “By capturing this ancient, 9-billion-year-old light, we

Saturn’s A Ring has oxygen, but not life

Data from the Cassini-Huygens satellite showing oxygen ions in the atmosphere around Saturn’s rings suggests once again that molecular oxygen alone isn’t a reliable indicator of whether a planet can support life.

That and other data are outlined in two papers in the Feb. 25 issue of the journal Science co-authored by University of Michigan engineering professors Tamas Gombosi, J. Hunter Waite and Kenneth Hansen; and T.E. Cravens from the University of Kansas. The papers b

Seeing the invisible – first dark galaxy discovered?

A British-led team of astronomers have discovered an object that appears to be an invisible galaxy made almost entirely of dark matter – the first ever detected. A dark galaxy is an area in the universe containing a large amount of mass that rotates like a galaxy, but contains no stars. Without any stars to give light, it could only be found using radio telescopes. It was first seen with the University of Manchester’s Lovell Telescope in Cheshire, and the sighting was confirmed with the Areci
