Erneuerbare Energien sind Energieformen, die das Erdsystem erzeugt und die mit der Dynamik des Systems in engem Zusammenhang stehen. Die Thermodynamik begrenzt dabei die Erzeugungsraten von Energie und damit die mögliche Nutzung als erneuerbare Energie.
The global estimate shows that – except for solar and wind power – the natural generation
Am MPIE entwickelte Eisenaluminid-Legierungen stellen eine kostengünstige und nachhaltige Alternative zu hochlegierten Stählen und Ni-Basislegierungen dar, vor allem wenn es um den Einsatz bei hohen Temperaturen in korrosiven Umgebungen geht.

Bis heute haben Astronomen mehr als 500 ‚Exoplaneten‘ gefunden, also Planeten, die um andere Sterne kreisen. Darunter gibt es eine Gruppe besonders großer Planeten, deren Bahn um ihren Stern sehr eng ist, die so genannten ‚heißen Jupiter‘.

Weekly death countscan be used to calculate how many more people are currently dying during the Covid-19 pandemic than would be expected according to trends in recent years. Internationally, there are clear differences: While in England the death counts in March and April were almost twice as high as in the previous five years, and in Sweden significantly more people died than in the comparable months of the previous years, the increase in Germany is moderate. However, all three countries seem to be past the peak of the curve.

How is it possible that HD 62623, a hot super-giant star on the verge of death, is surrounded by a disc, generally only associated with infant stars? Using long-baseline stellar interferometry at ESO’s VLT interferometer, a team led by Florentin Millour from Observatoire de la Côte d’Azur and Anthony Meilland from Max Planck Institute for Radio Astronomy could generate for the first time a three-dimensional high angular and high spectral resolution image of this star and its closest environment. They conclude that a solar-mass companion star is the key to this mystery. To attain their goal, the researchers adapted an imaging technique from radio astronomy which uses interferometric datasets.
supergiant stars are very bright stars, so bright, that they push their strong wind

In the light of the coronavirus pandemic, the National Academy of Sciences Leopoldina calls for a shift towards sustainable forms of economy, more European and international cooperation, and a strengthening of services of general interest and common goods that will make our societies more resilient to future crises. Among the authors of the statement are Jürgen Renn, Max Planck Institute for the History of Science, and Robert Schlögl, Fritz Haber Institute of the Max Planck Society and Max Planck Institute for Chemical Energy Conversion, supported by Christoph Rosol as coordinator of the Anthropocene Research Group at the Max Planck Institute for the History of Science.
