Giant Tornadoes Seen Erupting From the Sun
from National Geographic News
The sun produces giant tornado-like jets that stretch thousands of miles into space, new satellite data shows. The solar tornadoes typically last about ten minutes and occur near the sun's poles.
"These solar tornadoes are almost a thousand times faster than a terrestrial tornado and are very big," said Spiros Patsourakos, a researcher at George Mason University.
Scientists have known since the 1990s that jets of gas wider than North America were erupting from the sun's poles, but it is only now that they discovered these jets are rotating. That's because a new pair of NASA satellites called STEREO allowed the features to be observed from two directions at once, revealing their three-dimensional structures.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
