The black auroras

Most people have heard of auroras - more commonly known as the Northern and Southern Lights. Less familiar are phenomena known as black auroras, dark patches which often subdivide the glowing curtains of red and green light. A recent paper studies the phenomena of these black auroras.

By analysing data collected from ESA’s Cluster satellites for almost 15 years the scientists cast light on the physical processes taking place in auroral nurseries and the secrets of how the dark "cavities" in between the shimmering auroras are created. Associate Professor Tomas Karlsson, Space and Plasma Physics gives an example of the importance of the findings.

"For example, GPS signals can be modified by changes in electron content in the ionosphere, so that their navigational and timing accuracy are significantly reduced. Improved modelling of the ionosphere is necessary to make the necessary corrections."

The force of innovation

Associate Professor Luigi Vanfretti will participate in the upcoming so called “Bubble Session” on innovation organized by Tieto on March 16.

Bubble Sessions are dynamic think-tank events for discussing and exploring ideas at the intersection of business and technology. On the 16th of March, a video of the discussion on the force of innovation in a digitalised world led will be published, supported before and after by blogs, films, insights and other articles.

KTH technology in NASA mission

After a decade of planning and engineering, NASA is in its last weeks of preparation to launch the Magnetospheric Multiscale, or MMS, mission. MMS is scheduled to fly into orbit on board a United Launch Alliance Atlas V rocket at 10:44 pm on March 12, 2015.  The four MMS spacescraft are equipped with instruments designed by KTH scientists Professor Göran Marklund and his team at Space and Plasma Physics.
