Could low-altitude reconnection power Jupiter's polar aurorae?

Like Earth, Jupiter's magnetic field channels electrically charged particles into its atmosphere, resulting in the formation of brilliant aurorae near its poles. However, the brightness and variety of Jupiter's auroral emissions ...

Unravelling the knotty problem of the sun's activity

A new approach to analyzing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, ...

Scientists propose source of unexplained solar jets

Nothing seems more familiar than the sun in the sky. But mysterious swirls, jets, and flashes of powerful light that scientists cannot explain occur in the sun's outer atmosphere all the time. Now, researchers at the U.S. ...

Space scientists solve a decades-long gamma-ray burst puzzle

An international team of scientists, led by astrophysicists from the University of Bath in the UK, has measured the magnetic field in a far-off Gamma-Ray Burst, confirming for the first time a decades-long theoretical prediction—that ...
