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…
Their article, published in Astronomy & Astrophysics, reports the discovery of a jet of molecular hydrogen arising from a forming high-mass star located in the…
In a standard scanning tunneling microscope (STM) topographic image of the surface of a cuprate semiconductor (left) atoms are arranged neatly in a crystal…
A massive project to generate an all-color map of the galaxies in a small area of sky, utilizing four satellite telescopes and four ground-based telescopes, is…

The European Molecular Biology Laboratory (EMBL) has developed a new computational tool that makes images obtained with cutting-edge microscopes even sharper….
Like our body every cell has a skeleton that provides it with a shape, confers rigidity and protects its fragile inner workings. The cytoskeleton is built of…
But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more stable methods are needed. The…
What to do? Focus on the noise patterns. Building on earlier work by other groups, physicists at the National Institute of Standards and Technology (NIST) have…
Silver would be a natural choice for nanoscale and microscale electrical contacts because of its high conductivity, but it has one notorious drawback. In an…
For astronomers, mapping the distribution of the mass in the Universe from its light component is a considerable challenge. It is an exercise as complicated as…

“The new view from the STEREO spacecraft will greatly improve our ability to forecast the arrival time of severe space weather,” said Dr Russell Howard of the…
The co-ordinated observational campaign of Jupiter using Rosetta and New Horizons began this week. Jupiter remains a fascinating world of scientific mystery….
In preparation for New Horizon's approach of Jupiter, Chandra took 5-hour exposures of Jupiter on February 8, 10, and 24th. In this new composite image, data…
