science news 19.02.2020

Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary in italics in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without italics if I have any.

Scientists pioneer new way to study exoplanets
A team of scientists using the Low Frequency Array radio telescope in the Netherlands has observed radio waves that carry the distinct signatures of aurorae, caused by the interaction between a star's magnetic field and a planet in orbit around it.

First research results on the 'spectacular meteorite fall' of Flensburg
A fireball in the sky, accompanied by a bang, amazed hundreds of eyewitnesses in northern Germany in mid-September last year. The reason for the spectacle was a meteoroid entering the Earth's atmosphere and partially burning up. Planetologists at Münster University have been studying a part of the meteorite. They found out that the meteorite contains minerals that formed under the presence of water on small planetesimals in the early history of our solar system.

A real global player: Previously unrecognised bacteria as a key group in marine sediments
From the shoreline to the deep sea, one group of bacteria is particularly widespread in our planet's seabed: The so-called Woeseiales, which may be feeding on the protein remnants of dead cells. Researchers from the Max Planck Institute for Marine Microbiology in Bremen and the Royal Netherlands Institute for Sea Research NIOZ now describe the distribution, diversity and lifestyle of these bacteria in The ISME Journal.
