Who is liable when damage is caused by Global Navigation Satellite System?
Who shall be responsible or liable when damage is caused by Global Navigation Satellite System (GNSS)? Is it fair enough to force a GNSS provider to bear the burden of compensation given GNSS open signals are provided free of charge? And are current international laws adequate to deal with those questions?…

Giant cosmic tsunami wakes up comatose galaxies
Galaxies are often found in clusters, which contain many “red and dead” members that stopped forming stars in the distant past. Now, an international team of astronomers, led by Andra Stroe of Leiden Observatory and David Sobral of Leiden and the University of Lisbon, has discovered that these comatose…

LOFAR pioneers new way to study exoplanet environments
Using the Dutch-led Low Frequency Array (LOFAR) radio telescope, astronomers have discovered unusual radio waves coming from the nearby red dwarf star GJ1151. The radio waves bear the tell-tale signature of aurorae caused by an interaction between a star and its planet. The radio emission from a star-planet…
