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…
Researchers using supercomputer simulations have exposed a very violent and critical relationship between interstellar gas and dark matter when galaxies are…
Professor Robert Cernik and colleagues from The School of Materials have built a prototype colour 3D X-ray system that allows material at each point of an…
An early present for astronomers, the cloud suggests that hot gas from many star-forming regions leaks into the interstellar medium. The Orion nebula is the…
The HRSC took these pictures on 25 June 2006 in orbit 3155, with a ground resolution of approximately 16 m/pixel. Noctis Labyrinthus lies at approximately 6.5°…
The automatic deployment of these metallic blue 'wings' and the activation of the on-board navigation systems will transform the 20-tonne Automated Transfer…
The Venus Express space mission was launched in November 2005 and entered in planetary orbit in April 2006. Since then it has been regularly sending data and…
The systems are around the young stars UX Tau A and LkCa 15, located in the Taurus star formation region just 450 light years away. Using a telescope that…
“We are seeing this object in the early stages of stellar birth,” said U. of I. astronomy professor Leslie Looney, the lead author of a paper accepted for…

This month in Physics World, Eric Linder and Saul Perlmutter, both at the University of California at Berkeley, reveal how little we know about dark energy and…
In the new Hubble image we can also see a smattering of bright pink regions decorating the spiral arms. These are huge, relatively short-lived, clouds of…
On that date the planet will be in line with the Earth and Sun and from the ground will appear to be opposite the Sun in the sky (at opposition).This year Mars…
The ground-layer adaptive optics system, or GLAS, works with a high-tech pulsed laser. The laser beam is projected from a small telescope mounted behind the…
Because a high Q factor indicates a capacity for stable vibrations, the nanowires might be used as oscillators in nano-electromechanical systems for future…
