Magnetic Filament Creates Sun's Canyon of Fire

Is the sun finally waking up? After a stretch of relatively quiet solar activity, the sun unleashed an enormous burst of solar material late last month. The 200,000-mile-long (322,000 kilometer) magnetic filament ripped through the sun's atmosphere, leaving behind what looks like a gaping canyon of fire.

The scorching canyon traces the path where magnetic fields held the filament aloft before the eruption. Researchers at NASA's Goddard Space Flight Center in Greenbelt, Md., stitched together two days of data from the Solar Dynamics Observatory to create a short video of the immense solar phenomenon.

Happy Halloween! Lion cubs Sango and Sabi at the Denver Zoo celebrated the spooky holiday by playing around with a festive pumpkin. The precocious cubs pounced on the pumpkin in the primary yard of the zoo's Predator Ridge exhibit.

Sango is a 1-year-old male who arrived from the Ellen Trout Zoo in Lufkin, Tex., in July. The lion cub spent the past few months in mandatory quarantine, away from the eyes of the public. This week, Sango made his debut at the zoo, joining his mate, Sabi, in Predator Ridge. [Related - Boo at the Zoo: Animals Get Their Spook On]
