I spent a little while looking at today’s images from NASA’s Terra and Aqua satellites with their amazing MODIS imager that sends back true colour images from an altitude of around 700 km. Here are a few things I spotted in just a short period of browsing this evening. Click any image for a much larger view. Here is a view of just some Sahara sand blowing north into Greece

Before you say, that’s cool and move on, think about that for a second. WE CAN MEASURE WINDS FROM SPACE! We can also measure temperatures,  humidity, the amount of dust in the air, and even how stressed the plants in a drought are. Oh, and NASA did it all (and went to the Moon and Mars, and launched 100 space shuttles), all on less money than we spent on the

You heard about the big X4.9 solar flare at 00:50 GMT Monday I suspect. Phil Plait at Bad Astronomy is always the go to person on that, but NASA has a video out of the fare in different wavelengths that is pretty cool. The sunspot that produced the flare is rotating slowly around, and will be facing Earth in a few days. If it erupts again then we may be

2013 4th Warmest Year On Global Record

NOAA calculated that 2013 was the 4th warmest year on record globally, and NASA using a slightly different method ranked it 7th. In both cases, the ten warmest years on record have all been since 1998. With the bitter cold in the Eastern U.S. today, this is a perfect time to illustrate the difference between climate and weather. Climate change doesn’t mean it never  gets cold and snowy. It does

Ice-penetrating radar and drilling have led to some surprises in Greenland during the last few years.  The continent is bowl-shaped, it has a massive canyon running down its middle, and it contains a large aquifer of liquid water beneath the ice. NASA’s ice-penetrating radar is interpreted to show that the bedrock of the island is
