Welcome ! As a young French Marketing professional with a Master's in International Management I have been selecting since January 2007 the latest headlines and best researches on sustainable development, climate change, cleantech and the world energy sector. Sounds great ? Don't hesitate to subscribe now !
This is time for me to present my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). As always, this month was packed with beautiful images. It was difficult to select just ten. To the NASA, today’s picture :
The full fisheye frame shows everything above the horizon, including a lamp-illuminated landscape around the edges, and the zenith of the sky directly overhead. The image, however, may be more than beautiful.
I am absolutely still amazed at how many splendors can be seen at night. I just hope we may find a way to make our nights darker so more people can see them. Continue »
Even if Japan has a sensible energy policy with energy efficiency and low carbon solutions, some of its companies have original ideas. Indeed after space-based solar, some are studying installing panels on the moon.
The Shimizu Corporation is willing to put a 11,000 kilometers (6,800 miles) belt of solar panels to form the Luna Ring. All the energy would be transferred to Earth via microwaves or laser. This would thus require two transformations.
Of course, this project is not for tomorrow or the day after, it is more a vision for 2100 than anything else as the construction would require mining local resources and robots. Continue »
This is time for me to present my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). As always, this month was packed with beautiful images. It was difficult to select just ten. To the NASA, today’s picture :
” An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in the constellation of Orion. The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars.”

Today’s featured image is the supernova remnant E0102-72 captured in X rays. To the NASA : “Identified as E0102-72, the supernova remnant lies about 190,000 light-years away in our neighboring galaxy, the Small Magellanic Cloud.”
This is the occasion to focus a bit on how we can see our Universe in other means than the ordinary means. The Andromeda Galaxy is indeed interesting seen in ultraviolet. Continue »
I like creative ideas and I love everything related to space. Needless to say I am also a strong supporter of solar energies. Yet, I find that investing 14,7 billion euros in space-based solar is preposterous.
All this money will be invested to see if it is feasible to have one GW of power by 2030, when we need hundreds or thousands. I don’t even want to think of the power loss due to the 36,000 km between the plant and the consumers.
I wonder why Japan is putting so much money on such a project. 2 trillion yen could do some huge stuff in efficiency and more down to earth renewables. (Source: Bloomberg)
I wrote in February about how Mankind polluted space near our beautiful planet. I was then quoting the European Space Agency (ESA) which believed that there are 13,200 trackable objects larger than ten centimeters;
Now comes the NASA estimates that there are no less than 19,000 objects larger than ten centimeters in outer space, and between 500,000 and a million objects between one and ten centimeters.
For more on this phenomenon which may complicate even more the space race, please check out the full article on Ecoworldly : 4 Million Pounds of Space Junk Polluting Earth’s Orbit
Mankind polluted Earth’s oceans and atmosphere in an impressive way. According to the European Space Agency (ESA) it also polluted space in such a way that it represents a danger for satellites for the next 10,000 years !
To their website: “Since 1957, more than 4,800 space launches have led to an on-orbit population today of approximately 13,200 trackable objects, with sizes larger than 10 cm.”
Additionally, any object bigger than a centimeter represents an important danger for satellites because of their speed. There are up to 600,000 of them in terrestrial space. Continue »
The Japan Aerospace Exploration Agency (JAXA) launched the world’s first satellite dedicated to tracking global greenhouse gases (GHG) emissions. This will significantly increase our knowledge of their origin.
Dubbed Ibuki the new satellite will collect data in 56,000 locations around the world and most specifically in developing countries, where exact figures are lacking.
Tracking in a first time carbon dioxide emissions, it could also provide more useful data and be used for methane, another important greenhouse gas. Continue »
On December 24th, the famous Earthrise photo turned 40 years old. Andrew Revkin, New York Times’ journalist and blogger at Dot Earth published that day a most interesting note on this event.
Since I use this photo for this very blog I left a comment there. The day after I had the honor of a personal answer from Mr. Revkin himself. On his e-mail he presented me a video of an aurora Borealis seen from space.
This was the occasion for me to read out more on Dot Earth and to discover the videos published on YouTube by Mr. Revkin. Continue »
This is now official, even if there is no life on Mars, there is at least water. This most interesting founding is due to the US NASA and its Mars Phoenix Lander mission.
The mission begun on May 25th and was extended one month until the end of September as the findings are very interesting and the progress are very successful.
This occurs as I am reading the second book of the Martian Trilogy, a great science fiction series by Kim Stanley Robinson. Continue »
