Filming the Sun in 3d

US space agency Nasa has launched two spacecraft that are expected to make the first 3D movies of the Sun.

The Stereo mission will study violent eruptions from our parent star known as coronal mass ejections (CMEs). The eruptions create huge clouds of energetic particles that can trigger magnetic storms, disrupting power grids and air and satellite communications.


The mission is expected to help researchers forecast magnetic storms - the worst aspects of “space weather”.

“Coronal mass ejections are a main thrust of solar physics today,” said Mike Kaiser, the Stereo project scientist at the US space agency’s (Nasa) Goddard Space Flight Center. “With Stereo, we want to understand how CMEs get started and how they move through the Solar System.”

Japan launches satellite to study the Sun

A satellite designed to collect vital information about the Sun’s magnetic field successfully took off from Japan’s Uchinoura Space Centre early on Saturday local time. The Solar-B mission will attempt to understand how the field triggers solar flares and coronal mass ejections, which can cause communications blackouts on Earth. Data from the mission could even be used to predict when these massive explosions occur.
