Secrets of Saturns polar light show unveiled by BU-led team of astronomers
Aurora on Saturn behave in ways different from how scientists have thought possible for the last 25 years, according to new research by a team of astronomers led by John Clarke, a professor in BUs Department of Astronomy and in the departments Center for Space Physics. The teams findings have overturned theories about how Saturns magnetosphere behaves and how its aurora are generated. Their results will be published in the February 17 issue of Nature.
In an unusual coordination of two spacecraft, the team was able to gather what proved to be startling data on Saturns aurora. By choreographing the instruments aboard the Saturn-bound Cassini spacecraft and the Hubble Space Telescope circling Earth to look at Saturns southern polar region, Clarke and his team found that the planets aurora, long thought of as a cross between those of Earth and Jupiter, are fundamentally unlike those observed on either of the other two planets. The lights that occasionally paint the sky over Saturn may, in fact, be a phenomenon unique within our solar system.

UNH scientists help provide first-ever views of elusive energy explosion
16.11.2018 | University of New Hampshire
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
