Despite our fascination with screams, science knows relatively little about them.
Harold Gouzoules is one of the few scientists researching human screams. He collects them and analyzes their tone, pitch, and frequency to try and uncover the hidden patterns and complexities carried in one of the most intense human sounds.
Have you ever watched a scary movie where a crazed killer chases a person in an old, abandoned house during a thunderstorm? If you have, then you know how certain kinds of weather can add suspense and thrills to a horror movie. Thunderstorms can be loud and can produce the flickering lighting that adds to a scary movie. Some of the classic movies just had to include stormy weather. Follow the links inside for my picks of favorite scary weather scenes in horror movies.
Check out this beautiful new 6-minute short film from Daniel Lowe, called Night Visions: Astro La Palma. Daniel shot the film during a great adventure on the island of La Palma in the Canary Islands, Spain. Thanks for sharing, Daniel!
Justin Ng in Singapore, who recently contributed a photo to EarthSky’s Today’s Image series, contacted us again this week with a wonderful time-lapse video of Comet ISON, this year’s most-watched comet. Justin used a telescope and special camera to capture this view of the comet, which is not yet visible to the eye, but which many hope will become visible before this year ends. He acquired the time-lapse over 69 minutes on October 27, 2013.
The sun was active on Friday! NASA’s Solar Dynamics Observatory recorded a powerful an X1 flare on the sun early on Friday, and then again about 7 hours later. X-flares are the most powerful solar flares. The first flare peaked on October 25, 2013 at 0801 UTC (3:01 a.m. CDT in the U.S.). The second X-class solar flare, an X2, peaked at 1503 UTC (10:03 a.m. CDT). And this might not be the end of the flare activity. We’ll keep you updated.

Burning approach mixing practical philosophy and knowledge leads to near doubling of lizards and improves habitat.
In the spring of 2010, NASA’s Solar Dynamics Observatory, or SDO, provided its first views of the sun. Since then the spacecraft has had virtually unbroken coverage of our star, capturing one image every 12 seconds in 10 different wavelengths.
This video is a time-lapse sequence of SDO observations that spans three years in the life of the sun.
