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…
Greater numbers of ever-smaller components are required to fit on computer chips to meet the ongoing demands of miniaturizing electronic devices. Consequently,…
Produced for the Defense Threat Reduction Agency (DTRA), the Enhanced Mapping and Positioning System (EMAPS) captures a floor-plan-style map of the area…
Scheduled for launch in late 2013, MAVEN will be the first mission devoted to understanding the Martian upper atmosphere. The goal of MAVEN is to determine the…
A once-promising approach for using next-generation, ultra-intense lasers to help deliver commercially viable fusion energy has been brought into serious…
Previously, supernovae were divided into either core-collapse or Type Ia categories. Core-collapse supernovae are the explosion of a star about 10 to 100 times…
The discovery was made in the course of a study of a spectacular star, VY Canis Majoris or VY CMa for short, which is a variable star located in the…
In a breakthrough that could one day yield important clues about the nature of matter itself, a team of Harvard scientists have succeeding in measuring the…
CU-Boulder Professor Michael Shull and Research Associate David Syphers used the Hubble Space Telescope to look at the quasar — the brilliant core of an…
The first image shows the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. The natural-color image shows the…
Engineering a unique two-dimensional sheet of gold nanoantennas, the researchers were able to obtain the strongest signal yet of the photonic spin Hall effect,…
Carbon nanotubes can be used as quantum bits for quantum computers. A study by physicists at the Technische Universitaet Muenchen (TUM) has shown how nanotubes…
The universe according to Planck is expanding a bit more slowly than thought, and at 13.8 billion is 100 million years older than previously estimated. There…
Thanks to a supersensitive space telescope and some sophisticated supercomputing, scientists from the international Planck collaboration have made the closest…
Peptidases are essential for many biological processes and are therefore intensively studied within the research community. Scientists at the University of…
