Video: New evidence suggests not all space storms can be predicted
The twin STEREO probes that image the sun's activity have caught sight of a burp of ionised gas that blasted into space from our star's surface without warning.
The find confirms suspicions that some solar ejections can occur even though the surface of the sun looks tranquil.
The eruption was a coronal mass ejection (CME) – a bubble of plasma that, if energetic enough and pointed at Earth, could zap satellites, endanger astronauts, and knock out power grids (see Space story alert: 90 seconds from catastrophe).
