Clocks are important - and complicated - in Global Navigation Satellite Systems (GNSS) or GPS as most people know it as. I assume butterflies also have a rather sophisticated chronometer...:-)

We are pretty preoccupied with climate change on this planet these days. This week the Climate Week is taking place in New York City, partly preparing for the big Copenhagen meeting in December where we hope to get the replacement of the Kyoto Agreement in place. (I said HOPE).
I always say I do not discriminate against any of the planets including planet Earth. NASA must have the same philosophy. Look at this awesome study of the changing climate of Mars all revealed by laser techniques. :-)
Satan, Saturn is Splendid! (I'm sure I can find more words starting with the letter S...but I won't. :-)) JPL has made a delicate presentation - with music on top - of Saturn and surroundings.
The media will be packed with climate change articles and opinions as we get closer to the Copenhagen meeting in December. I'll be contributing to the discourse, too. This is one fresh article written about the ongoing work by among others the Stockholm Environment Institute.
And seals are not the only species we can expose to thermal imaging - here are some thermal images of my family species taken at La Villette in Paris. :-)
And Nancy shows us how much sharper the new Hubble butterflies are compared to the old ones...almost with the speed of light she does it too!
I've collected a whole bunch of the new Hubble images. I simply couldn't help myself. They are gorgeous. And there is a quasar among the new products. I have an extremely weak spot for quasars. :-)
