A scientist using the Solar and Heliospheric Observatory (SOHO) has found a way to forecast solar radiation storms. The new method offers as much as one hour advance warning, giving astronauts time to seek shelter and ground controllers time to safeguard their satellites when a storm is approaching.
“Solar radiation storms are notoriously difficult to predict – they often take … Read the rest of this article

“We have mapped the temperature variations with longitude across the entire surface of a planet that is so far away, its light takes 60 years to reach us,” said Heather Knutson of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., lead author of the paper describing HD 189733b.
The two planets are “hot Jupiters” – sizzling, gas giant planets that … Read the rest of this article
