Violent Sunspot Group AR 1302 Unleashes a Flare  Image Credit: jp-BrahicExplanation: One of the most active sunspot groups in years is currently crossing the Sun. AR 1302 first came around the Sun's edge last week and is so large it can be seen without a telescope. Coronal Mass Ejections from AR 1302 have already caused strong geomagnetic storms including notable aurora activity around both of Earth's poles. Pictured above, plasma was left magnetically hanging above the Sun's ... Full Story

Milky Way Over Switzerland Credit: Stephane Vetter (Nuits sacrees) Explanation: What's visible in the night sky during this time of year? To help illustrate the answer, a beautiful land, cloud, and skyscape was captured earlier this month over Neuchâtel, Switzerland. Visible in the foreground were the snow covered cliffs of the amphitheater shaped Creux du Van, as well as distant trees, and town-lit clouds. Visible in the night sky (at midnight) were galaxies including ... Full Story

Mammatus Clouds Over Olympic Valley Credit & License: Matt Saal (Wikipedia) Explanation: What's happened to these clouds? Normal cloud bottoms are flat because moist warm air that rises and cools will condense into water droplets at a very specific temperature, which usually corresponds to a very specific height. After water droplets form that air becomes an opaque cloud. Under some conditions, however, cloud pockets can develop that contain large droplets of ... Full Story

De Martin Explanation: The North America Nebula can do what most North Americans cannot -- form stars. Precisely where in the nebula these stars are forming has been mostly obscured by some of the nebula's thick dust that is opaque to visible light. However, a new view of theNorth America Nebula ...
