Geoengineering versus a volcano

Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun's radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new ...

Discovering trailing components of a coronal mass ejection

Using Green Bank Observatory in West Virginia, PSI Associate Research Scientist Elizabeth A. Jensen's team observed radio signals from the MESSENGER spacecraft and discovered that solar eruptions known to cause communication ...

SDO reveals how magnetic cage on the Sun stopped solar eruption

A dramatic magnetic power struggle at the Sun's surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights the role of the Sun's magnetic landscape, or topology, in the development ...

Toward a better prediction of solar eruptions

A single phenomenon may underlie all solar eruptions, according to researchers from the CNRS, École Polytechnique, CEA and INRIA in an article featured on the cover of the February 8 issue of Nature. They have identified ...

Tracking a solar eruption through the solar system

Ten spacecraft, from ESA's Venus Express to NASA's Voyager-2, felt the effect of a solar eruption as it washed through the solar system while three other satellites watched, providing a unique perspective on this space weather ...
