Solar cycle 25: The sun wakes up

The sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy, with few sunspots, bright flares or massive ejections of magnetized plasma emanating from its surface. ...

Spinning black hole powers jet by magnetic flux

Black holes are at the center of almost all galaxies that have been studied so far. They have an unimaginably large mass and therefore attract matter, gas and even light. But they can also emit matter in the form of plasma ...

Breakthrough method for predicting solar storms

Extensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts ...

New technology promises to revolutionize nanomedicine

Researchers from the Moscow Institute of Physics and Technology and their colleagues from Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry and Prokhorov General Physics Institute of the Russian Academy of Sciences ...

New sunspots potentially herald increased solar activity

On May 29, 2020, a family of sunspots—dark spots that freckle the face of the sun, representing areas of complex magnetic fields—sported the biggest solar flare since October 2017. Although the sunspots are not yet visible ...

Study shows our sun is less active than similar stars

By cosmic standards the sun is extraordinarily monotonous. This is the result of a study presented by researchers from the Max Planck Institute for Solar System Research in the upcoming issue of Science. For the first time, ...
