Mom, maybe you’d better light up a Marlboro
Hey, you. Yes, you. Look look like a real cool dude. Not a square! Squares just don’t understand what it’s like to be in the know and walk loose. That’s why you smoke. And you just don’t smoke any brand of tobacco, you smoke the kind your doctor recommends: Chestermarlbocamel. This three in one blend brings together the spirit of 1950s carte blanche advertising and throat cancer all under one filter. So go ahead, take a drag. You deserve it.

Stunning new pictures of Mars show half-mile wide crater complete with sand dunes

Saturday, August 15, 2009

It is one of the most dramatic images to ever emerge from Mars.

In fact, this extraordinary photograph is so clear that even the sand dunes at the base of the half-mile wide canyon are visible.

Experts even believe that they can see the tracks of a Mars lander on the left-hand corner of the Victoria Crater.

The image, taken by Nasa, shows in vivid detail the canyon which has lain undisturbed for somewhere between 10million and 100million years.

Its peaceful history was only broken when a Nasa rover landed in 2006 and explored the area until August last year, leaving behind its trademark tracks.

The space organisation's Mars Reconnaissance Orbiter beaned down this stunning shot of the 800-metre-wide crater.

The High Resolution Imaging Science Experiment (HiRISE) camera, which took the camera, has been a useful aide in Mars exploration.



Its images helped the Mars Opportunity rover navigate around the edge of the crater, and even take cover when winds kicked up a dust-storm in 2007.

Although the image looks like a 'top-down' shot, it was actually taken at an angle more akin to a passenger looking out of a plane window, allowing NASA to see more of the steep walls of the crater.

Another image from the HiRISE captures a 'dust devil' leaving a trail and casting a shadow.





The whirlwinds form as the ground heats up during the daytime, which warms the air immediately above the surface.

The hot layer of air rises and the cooler air above falls, and a horizontal gust of wind causes the air and any dust to rotate.

Early estimates pin Victoria Crater at somewhere between 10 million and 100 million years old, but the rocks within the depression themselves are likely much older - as in a few billion years in age, researchers said.

Amazing pictures of 'hole in the clouds' from volcano eruption

Thursday, June 25, 2009

A chance recording by astronauts on the International Space Station has captured the moment a volcano explosively erupted, sending massive shockwaves through the atmosphere.

Sarychev Peak, one of the most active volcanoes in the world, had been sitting quietly in the Kuril Island chain near Japan for 20 years, when it suddenly sprang to life on June 12.

Fortuitously, the International Space Station was flying overhead at the time, and managed to capture this spectacular image of the ash-cloud tearing through the atmosphere, sending clouds scattering in its wake in a perfect circle.

The station, which orbits the earth from a height of 220 miles, makes nearly 16 orbits of our planet every 24 hours, and happened to be in the perfect spot to see the dramatic eruption.

The unique images have provided a wealth of new information about the eruption process, and volcanologists are now excitedly poring over the data.

Most unique is the mist-like 'roof' to the cloud, believed to be either steam or condensing water pushed ahead of the advancing cloud of ash. Known as a 'pileus cloud', it lasts just moments, making this a rare snapshot.


Also visible, far below on the hillside, is the thunderous pyroclastic flow of super-heated rock as it cascades down the mountainside. When most people picture volcanoes, they imagine red-hot lava flows. Pyrochastic flows are their deadlier older brother. Appearing at the start of an explosive eruption, they can travel at 130mph, meaning there's nearly no escape for anyone or anything caught in its path.

But the most stunning aspect of the picture is the effect on the clouds: As the ash column punches its way towards the top of the atmosphere, the shockwave causes the clouds to scatter.

An alternative theory, one which these pictures is helping to test, is that as the ash rises, the surrounding air is pushed down, where it warms, and the increased heat causes the clouds to evaporate.

As the ISS continued its orbits over the next days, the astronauts could follow the plume as it drifted away from the island, incidentally causing disruption on nearby flight paths.




The volcano is part of a seismically active cluster of islands running North East from Japan's Hokkaido Island, and up towards Russia's Kamchatka Peninsula.

There are disputes between Russia and Japan over who owns which islands, but Matua Island, where the volcano is located, is generally agreed to be Russian territory. The Japanese call it Matsuwa Island.

The last explosive eruption from Sarychev happened in 1989, with eruptions in 1986, 1976, 1954, and 1946 also producing lava flows.

Ash from the eruptions has been recorded to reach more than 1,500miles from the volcano and commercial airline flights have been disrupted.

The height of the plume was measured at five miles high - a huge distance into the sky, although not enough to worry the astronauts peering down from above.

The International Space Station was first constructed in 1998 and is scheduled to be completed in 2011.
