Fixing space-physics mistake enhances satellite safety

Correcting 50-year-old errors in the math used to understand how electromagnetic waves scatter electrons trapped in Earth's magnetic fields will lead to better protection for technology in space.

Tracking near-Earth cosmic explosions

When massive stars or other stellar objects explode in the Earth's cosmic neighborhood, ejected debris can also reach our solar system. Traces of such events are found on Earth or the moon and can be detected using accelerator ...

Large effect of Solar activity on Earth's energy budget

This is the result of a new study by researchers from DTU Space at the Technical University of Denmark (DTU) and of The Hebrew University of Jerusalem, who have traced the consequences of eruptions on the Sun on clouds and ...

Stellar explosion in Earth's proximity

When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova—a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned ...
