It sounds astonishing, incredible, that New Horizons goes so far away

About 100 amino acids were found in the Murchison meteorit, fallen in 1969, in Australia. Among those amino acids, it seems that about 20 exist in cells. The Murchison meteorit derives from traces of asteroids, present at the time of the birth of the solar system 4,55 billion years ago. I know that ...

R* = the average rate of star formation per year in our galaxy f p = the fraction of those stars that have planets n e = the average number of planets that can potentially support life per star that has planets f ℓ = the fraction of the above that actually go on to develop life at some point f i = ...

As we still didn't find out at least another one habitable planet, we should learn to love each others more than what we do. "We stand together, taken away on the same planet, as the crew of a same ship" (Saint-Exupéry). I am sure it is possible, but i wonder how long the road is. Maybe we...

I love all the new pictures, especially : the poppies in the moonlight, the huge full moon beyond pine's branches, and Milky Way over Balanced Rock!!!
A lot of wonderful pictures

Hello

Here is a sunset at Cooper Pedy, an Australian town, called the “opal capital of the world”, in the Outback (cf. http://www.cooberpedy.sa.gov.au/site/page.cfm?u=191 ). The population was less than 2,000 people over there, in 2006.

Thanks for looking,
Best regards,

Céline

It is great, your picture Stéphane is so wonderful !!!
Félicitations for making the milky way so clear and magic over the Creux du Van
Have a very nice day,

Céline

Hello

Here are two pictures i have taken near Bernex, in the Alpes, in France.
Thanks for looking, have a very nice day !!!

Hey :) Clouds are reflecting lights, so light pollution is annoying for astronomers in cities, like Paris. The sky is almost orange in Paris, all the time. In 1667, when the Observatory of Paris was built, it was in the countryside, but the city of Paris has expanded, thus now the Observatory belong...

Hello,

I love "Starry Night over Mt Kilimandjaro" by Kwon and O Chul !

Here are two pictures.
Have a very nice day!

Yes Stephane,the Creux du Van is a sacred place! I regret i didn't go there, since i have seen your wonderful picture! The Creux du Van seems to be at about 100 km "à vol d'oiseau" from Geneva, where i have gone a few years ago. Maybe i could go, over there, one day:D The California Nebula...

Hi

With delay, there is a picture i have posted in November. It is a skyview i have taken in Madrid, at sunset, in September 2010.
Have a very nice day,

Hello :) I LOVE the wonderful picture called " Milky Way other The Creux du Van in Switzerland " from Stephane Vetter!!! :D :D :D The " M1 Animation (4 years)" from Martin Fiedler is so impressing! He needed so much patience!! I put two pictures here. In the Outback, at the very ...

Particles (including molecules) much smaller than 0.5 microns will be Rayleigh scatterers that are much more effective in scattering blue light than red light. (It is the same reason that the sky is blue.) (...) The cracks on Europa indicate that the overlying ice sheet may be thin enough to penetr...

I love this picture, it is wonderful !!!
Such a great, great image, which makes me dreaming
David Kaplan is a gifted artist!

Hello :) Here is a colorful drawing, published in the newspaper "Le Parisien", on Sunday 15th May 1910. At this time, the Halley cometa appeared in the sky, thus parisians went out to see it, at night, on the roofs of the city. The Halley cometa aroused everybody's curiosity. I hope you en...

Hello :) In initial flybys, Cassini's instruments detected carbon, hydrogen, oxygen, nitrogen, and various hydrocarbons in the plume gasses. But there were none of the elements of salt that ocean water should contain. Why do ocean water should contain salt? "Where's the heat coming from on this...

Hello :) Can there be life? http://www.youtube.com/watch?v=3C84cYlHzn4 Thank you!!! Very interesting :) It is great to be able to get the dimensions of Europa, with enough accuracy, in order to determine how tides, below the icy surface of this satellite, can change the form of Europa! It might be s...

Hello :) Hello everyone, I am the author of this picture (...) There is a famous painting called "Vädersoltavlan" depicting an intricate halo over Stockholm in 1535. It is also the oldest known representation of Stockholm. My photograph is not from the same spot and not exactly in the same...

Hello :) This is such a great, wonderful picture! In the other image http://www.nasaimages.org/luna/servlet/detail/NVA2~14~14~25039~124507:cryobot-hydrobot it seems there is water below ice on Europa. I hope hydrorobots will find out very interesting life forms over there. The spacecraft Galileo was...

Hello

I post my pictures here.

You are right, the Helix nebula does look like something out of Yellowstone, and I know what you are referring to: The Grand Prismatic Spring . If I believed in psychics (and I don't), I would think you are one because I was working last week on a draft for a painting of "The Grand Prismatic S...
