High-Flying Ice Clouds Spotted From Space

Glowing high-altitude ice clouds were spotted over western Asia by the crew of the International Space Station on June 13 during one of their 16 daily orbits of the planet… the photo above shows the wispy filaments shining brightly in the mesosphere above western Iraq and Uzbekistan.

A View From The Top

From the top of the atmosphere, that is! This gorgeous photo, taken from the Space Station on November 24, 2011, looks over our planet’s limb just after orbital sunset. We get a good look at cloud structures, the thin shell of our atmosphere (it’s always surprising how thin it really is), airglow, stars, and what…

The Colors of Titan’s Sky

Made from one of the most recent Cassini images, this is a color-composite showing a backlit Titan with its dense, multi-layered atmosphere scattering sunlight in different colors. Titan’s atmosphere is made up of methane and complex hydrocarbons and is ten times as thick as Earth’s. It is the only moon in our solar system known to have…

A Glow From Above

Many of the recent images and videos I’ve shared here have featured amazing views from the Space Station. At 250 miles up, astronauts aboard the ISS enjoy an unprecedented and privileged view of our world. In addition to having a vantage point from which to view the countries, continents and oceans below, they also get…

Goodnight Moon

Another stunning view from the Space Station, this photo was taken by Expedition 28 astronaut Ron Garan on July 31, 2011 and shows the Moon seeming to sink into the ocean of air that is our life-supporting atmosphere. As the Moon passes behind Earth’s limb it appears to get squished because of light being refracted…

Mars’ Underground Atmosphere

Scientists have spotted an underground reservoir near Mars’ south pole the size of Lake Superior… except that this lake is filled with frozen carbon dioxide – a.k.a. “dry ice”! A recent report by scientists at the Southwest Research Institute in Boulder, CO reveals variations in Mars’ axial tilt can change how much carbon dioxide gets…

A Varying Venusian Vortex

Our neighboring planet Venus really is a world of extremes; searing surface temperatures, crushing air pressure, sulfuric acid clouds…Venus pretty much pushes the envelope on every aspect of rocky-planet existence. And now here’s one more thing that made scientists do a double-take: a shape-shifting vortex swirling around Venus’ south pole! The presence of a cyclonic…

Saturn’s Skyline

A raw image from Cassini taken on January 9, 2011, this minimally-composed image is actually quite fascinating (IMO): it’s a look at the upper levels of Saturn’s atmosphere in methane wavelength! Yes, Saturn is a gas giant and most of its volume is made up of hydrogen and helium, but there are layers of its…

Earthshine

It may look like a science fiction film but it’s very much science reality: a view from the window of the International Space Station, taken on November 7 by astronaut Doug Wheelock, shows external structures lit by a cool blue light reflected off our planet – “Earthshine” – while the bright crescent of dawn blooms…

Saturn’s “Storm Alley”

Dark swirling vortices march along Saturn’s “storm alley” in this section of an image taken by Cassini on May 19, 2008. (It was recently uploaded as a featured image on JPL’s Flickr page.) Storms on Saturn are huge and powerful, with winds blowing many hundreds of miles per hour and often featuring lightning ten thousand…

Sweet Sixteen: Jupiter in Motion

This video, made up of 16 images assembled from Voyager 1 data by astro-artist Björn Jónsson and animated by Ian Regan, shows a time period spanning 16 Jupiter days (about 7 days Earth-time) wherein we can briefly observe the dynamics of the different cloud belts and spinning storms in the gas giant’s swirling atmosphere. Especially prominent is the…

Solving a Martian Mystery

“The Red Planet bleeds. Not blood, but its atmosphere, slowly trickling away to space. The culprit is our sun, which is using its own breath, the solar wind, and its radiation to rob Mars of its air. The crime may have condemned the planet’s surface, once apparently promising for life, to a cold and sterile…
