That the universe is expanding has been known for almost a century, but its exact rate of expansion remains one of cosmology's most hotly debated questions. A team from the Technical University of Munich (TUM), Ludwig Maximilians University (LMU) and the Max Planck Institutes for Astrophysics (MPA) and for Extraterrestrial Physics (MPE) has now imaged and modelled an exceptionally rare supernova

In Earth history, a few episodes stand out for their extreme cold, when geologic evidence indicates that ice covered the planet from pole to pole during so-called Snowball Earth events. These episodes represent some of the coldest conditions the planet has ever experienced, with the entire surface essentially below the freezing point of water. Scientists link the onset and end of these global gl

Small satellites have become attractive for space missions because they offer low cost and flexibility, but their growth has been limited by the lack of compact, efficient propulsion systems that work well in the vacuum of space. In orbit, spacecraft can only change their motion through reaction force, and traditional chemical rockets produce thrust by burning fuel to generate high temperature g
