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 !
I love the picture Earthrise. Since I first discovered it back to 2007, it has become the central part of my communications; It is featured on my Twitter account, my About.me page, my business cards and on the header of this website.
So when Andrew Revkin from the New York Times tweeted about the “ Nice video assembly of Apollo 8 astronaut audio & photos leading to iconic “EARTHRISE” image “ I just had to click.
To say the least, I wasn’t disappointed as this making of clearly explains how such a beautiful image was created by the Apollo 8 crew. Continue »
What if we could in the same time slow down climate change, increase health and boost agriculture ? Is this too good to be true ? No, as to a NASA scientist we could do just that by focusing on both methane and soot (black carbon).
Out of the 400 ideas that were studied, these 14 were chosen as they have a direct and immediate impact on people’s lives. None of these methods are concerning carbon dioxide, which also have to be tackled in the meantime.
One of the main ways is switching to cleaner burning cookstoves. I have previously tackled this topic here and explained how this could save two million people per year. Continue »
I think this is a record of some sort as I am only publishing today my selection of astrophotographies for February… Anyway, here is my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD).
This month is a bit special as my favorite is a video : ” How big is our Sun compared to other stars? In a dramatic and popular video featured on YouTube, the relative sizes of planets and stars are shown from smallest to largest. “
The video is visible in the full post below. This clearly demonstrates how infinitesimal we are and how our beautiful planet is tiny, thus the need to protect our ability to live on it… Continue »

o CleanTechies : ” According to a new NASA-funded study, Greenland and Antarctic ice sheets are losing mass at a much faster rate than previous model forecasts have predicted. “
” Results suggest that the ice sheets, found only in Antarctica and Greenland, are melting faster than mountain glaciers and ice caps and are poised to become the dominant factor in global sea-level rise. “
For more frightening details about how fast this phenomenon is occurring, I recommend you to read the full article. This shows that, more than ever, we have to act…
With some late – again – I would like to propose you my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). As always, here is my selection of the best pictures of last month. Today’s picture :
Sometimes it looks like the Sun is being viewed through a large lens. In this case, however, there are actually millions of lenses: ice crystals. As water freezes in the upper atmosphere, small, flat, six-sided, ice crystals might be formed.
I am absolutely still amazed at how many splendors can be seen at night (and day). I just hope we may find a way to make our nights darker so more people can see them. 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, here is my selection of the ten best pictures of last month. Today’s picture :
” On Reunion Island, it is known simply as “The Volcano.” To others, it is known as the Piton de la Fournaise, which is French for the Peak of the Furnace. It is one of the most active volcanoes in the world. “
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 »
To the World Meteorological Organization the main greenhouse gases – carbon dioxide, methane and nitrous oxide – keep increasing in the atmosphere, and this despite the efforts and the economic recession. To the WMO :
” The report highlights concerns that global warming may lead to even greater emissions of methane from Arctic areas. To the Bulletin, total radiative forcing of all long-lived greenhouse gases increased by 27.5% from 1990 to 2009.”
Meanwhile, NASA reports 2010 is the hottest year on record so far. It seems that more than ever before, drastic action is needed. Will the call be heard in Cancun ? Continue »
This is time for me to present my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). This month was a bit special as I could only select ten of them.
To the NASA, today’s picture : “Look closely at this surreal nightscape. In the dreamlike scene, star trails arc over an old ship run aground on a beach near Gytheio, Peloponnesus in southern Greece.”
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 »
I love both Impressionism and beautiful astronomy pictures. So, when the NASA features Starry night over the Rhone, by Vincent van Gogh I only can write about it. As the NASA puts it :
How can the majesty of the night sky best be captured in a painting? This was a continual challenge for Vincent van Gogh, a famous painter in the late 1800s who pioneered stirring depictions of star filled skies into several of his works.
Pictured above is van Gogh’s Starry Night Over the Rhone, where the French town of Arles is depicted complete with gas lights reflecting off the Rhone river. Continue »
This is time for me to present my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). This month was a bit special as I could only select eight of them. To the NASA, today’s picture :
Storms on the distant horizon and comet dust raining through the heavens above are combined in this alluring nightscape. (…) the composite of 8 consecutive exposures captures the flash of lightning and a bright Perseid meteor.
This might be my last selection of astrophotographies since I am increasingly aware that this kind of posts isn’t at all in the range of this blog. What do you think ? Continue »
