Fly-through Mars’ Grander Canyon

Using images taken from the High-Resolution Stereo Camera aboard ESA’s Mars Express, this fly-through was created. It is located in the northernmost part of Valles Marineris.

The mystery of the missing waves on Titan

Saturn’s giant moon Titan is dotted with hydrocarbon lakes and seas that bear an uncanny resemblance to bodies of water on Earth. Strangely, though, Titan’s lakes and seas have no waves.

Take a picture of Saturn

Take a picture of Saturn in the sky tonight. You could capture a view like this one. Recorded just last month looking toward the south, planet Earth and ruins of the ancient temple of Athena at Assos, Turkey are in the foreground. The Moon rises at the far left of the frame and Saturn is the bright “star” at the upper right, near Virgo’s alpha star Spica (picture with labels). If you do take a picture of Saturn or wave at Saturn and take a picture, you can share it online and submit it to the Saturn Mosaic Project. Why take a picture tonight? Because the Cassini spacecraft will be orbiting Saturn and taking a picture of you.

Thailand before and after flooding

In this true-colour satellite image, we see flooding in Ayutthaya and Pathum Thani Provinces in Central Thailand (right), compared to before the flooding (left).
The Chao Phraya River forms at the confluence of smaller rivers in central Thailand, and flows southward to the Gulf of Thailand. En route to the sea, the river passes through Ayutthaya. First established in the fourteenth century, Ayutthaya lies north of Thailand’s capital city of Bangkok, and the floods plaguing Thailand in October 2011 did not spare this historic city.

Giant sinkholes and road collapses (23 pictures)

A sinkhole, also known as a sink-hole, sink, swallow hole, shakehole, swallet or doline, is a natural depression or hole in the Earth’s surface which may have various causes. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes in sandstone. Others are formed as a result of the collapse of old mine workings close to the surface.
