(PhysOrg.com) -- A German radar satellite TanDEM-X was launched on June 21 by the German Aerospace Center (DLR) to join an identical satellite, TerraSAR-X, which was launched in 2007. The two satellites will fly in formation ...
Microscopy techniques that incorporate mid-infrared (IR) illumination holds tremendous promise across a range of biomedical and industrial applications due to its unique biochemical specificity. However, the method is primarily ...
(Phys.org) —ESO's Very Large Telescope Interferometer has gathered the most detailed observations ever of the dust around the huge black hole at the centre of an active galaxy. Rather than finding all of the dust in a doughnut-shaped ...
