Starspots: Revving up the variability of solar-like stars

In cosmic comparison, the Sun is a bore. While the brightness of some other stars with similar characteristics fluctuates strongly, the Sun's variations are much more moderate. Scientists from the Max Planck Institute for ...

Cosmic X-rays reveal a distinct signature of black holes

An international team of astrophysicists has found distinctive signatures of black hole event horizons, unmistakably separating them from neutron stars, which are objects comparable to black holes in mass and size but confined ...

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, ...

Ten things we've learned about the sun from NASA's SDO this decade

In February 2020, NASA's Solar Dynamics Observatory—SDO—is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the sun, studying how the sun creates solar activity and drives ...

A sphere of colour
