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…
This is one of several recommendations made in a report published today [13th September 2007] by the UK Space Exploration Working Group [SEWG], an advisory…
The pictures show the moon's yin and yang – a white hemisphere resembling snow, and the other as black as tar. Images returned late Tuesday and early Wednesday…
They determined the spin and orbital periods of the binary star Paloma. They found that the Paloma system has a weird way of rotating that fills the gap…
They appear when particles in the electrically conductive gas (plasma) called the solar wind hit the earth’s atmosphere at an altitude of roughly 100…
The announcement, culminating seven years of research, will be published in the Sept. 13 issue of the journal Nature.The news provides a preliminary picture of…
The object’s minimum mass is only about 7 times the mass of Jupiter. But instead of orbiting a normal star, this low-mass body orbits a rapidly spinning…
Scientists who dream of shrinking computers to the nanoscale look to atomic spin as one possible building block for both processor and memory, yet setting the…
The Microsoft Institute for High Performance Computing at the University will be providing access to the Microsoft Compute Cluster Service through a Globus…
The researchers are developing an automated tool, called ConceptDoppler, to act as a weather report on changes in Internet censorship in China. ConceptDoppler…
University of Arizona astronomers who collaborated in the observations say that neon could show which stars retain their surrounding dust-and-gas disks needed…
In the quest for creating computer chips with ever-smaller feature sizes, chip manufacturers are exploring extreme ultraviolet lithography as the next…
This discovery, published today in Nature, provides a somewhat preliminary picture of what could be the destiny of our Earth once the Sun has exhausted its…
A report, Physics and the Scottish Economy, released today, Thursday, 13 September, by the Institute of Physics in Scotland (IOP), shows that more than £8…
The pictures were taken in orbit 3103 on 10 June 2006 with a ground resolution of approximately 16 metres per pixel. The mouth of Tiu Valles is an estuary-like…
To find out, the European Science Foundation (ESF), European Space Agency (ESA) and the European Space Policy Institute (ESPI) are co-hosting a conference in…
