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…
The use of near-infrared interferometry allowed the team to resolve a ring-shaped dust distribution (generally called “dust torus”) in the inner region of the…
Observations with NASA's Chandra X-ray Observatory have provided the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas…
Their research allows double ionization events to be observed at the time scale of attoseconds, which are one-billionth of a billionth of a second. The…
Carbon nanotubes and graphene are both made up of carbon and have unique properties. Graphene comprises an atom-thick layer of carbon atoms, while carbon…
It will provide the German and the international community of solar physicists with new and better instrumentation which will enable them to investigate our…
So far, astrophysicists thought that super-massive black holes can only influence their immediate surroundings. A collaboration of scientists at the Heidelberg…
To promote EGNOS, the European GNSS Agency (GSA) is offering a special prize for the most promising idea using the system. The prize is part of this year's…

The findings, published today in a set of Science papers, will help scientists better understand the early solar system and processes that occurred as it…
Earth itself certainly has one of these bow shocks on the sunward side of its magnetic environment, as do most other planets and many stars. A collection of…
Stars are thought to form in interstellar space from dark clouds of gas and dust. Their properties are expected to depend on the conditions of their dusty…
When UCLA's Christopher T. Russell looks at the images of the protoplanet Vesta produced by NASA's Dawn mission, he talks about beauty as much as he talks…
It turns out we've been missing a version of the famous “packing problem,” and its new guise could have implications for cancer treatment, secure wireless…
The scientific results are now being published in a special issue of the European journal “Astronomy & Astrophysics” (Volume 542, May 10) along with reports on…
All large galaxies have a massive black hole at their centre, each millions of times the mass of a single star. For over a decade scientists have been puzzled…
