Researchers find space radiation is increasingly more hazardous

It might sound like something from a science fiction plot – astronauts traveling into deep space being bombarded by cosmic rays – but radiation exposure is science fact. As future missions look to travel back to the moon ...

Three NASA satellites recreate solar eruption in 3-D

The more solar observatories, the merrier: Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the Sun—an effort made possible only by combining data from ...

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 ...

Swarm trio becomes a quartet

With the aim of making the best possible use of existing satellites, ESA and Canada have made a deal that turns Swarm into a four-satellite mission to shed even more light on space weather and features such as the aurora ...

Monitoring solar activity

Living near a star is risky business, and positioning a spacecraft near the sun is a very good way to observe rapidly changing solar activity and deliver early warning of possibly harmful space weather. ESA is now looking ...
