NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole.

In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph(150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.

NASA’s Cassini spacecraft observes Storm on Saturn devour itself

NASA - National Aeronautics and Space AdministrationPasadena, CA – Call it a Saturnian version of the Ouroboros, the mythical serpent that bites its own tail. In a new paper that provides the most detail yet about the life and death of a monstrous thunder-and-lightning storm on Saturn, scientists from NASA’s Cassini mission describe how the massive storm churned around the planet until it encountered its own tail and sputtered out.

It is the first time scientists have observed a storm consume itself in this way anywhere in the solar system.

This set of images from NASA's Cassini mission shows the evolution of a massive thunder-and-lightning storm that circled all the way around Saturn and fizzled when it ran into its own tail. The storm was first detected on Dec. 5th, 2010. That month, it developed a head of bright clouds quickly moving west and spawned a much slower-drifting clockwise-spinning vortex.

NASA’s AIM researchers discover Meteor Smoke in the makeup of Noctilucent Clouds

 

Written by  Dr. Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Anyone who’s ever seen a noctilucent cloud or “NLC” would agree: They look alien. The electric-blue ripples and pale tendrils of NLCs reaching across the night sky resemble something from another world.

Researchers say that’s not far off. A key ingredient for the mysterious clouds comes from outer space.

“We’ve detected bits of ‘meteor smoke’ imbedded in noctilucent clouds,” reports James Russell of Hampton University, principal investigator of NASA’s AIM mission to study the phenomenon. “This discovery supports the theory that meteor dust is the nucleating agent around which NLCs form.”
