To boldly go where only Astrophysicians have gone before. What I find interesting (and can roughly understand) in Astronomy & Space exploration these days.
New images from the far side of the moon have been acquired from video cameras on NASA's moon spacecraft mission called the Gravity Recovery And Interior Laboratory (GRAIL).

Astronomers said Wednesday that each of the 100 billion stars in the Milky Way probably has at least one companion planet, adding credence to the notion that planets are as common in the cosmos as grains of sand on the beach.
Wow! This is big and science goes fats. Back in 1994, we weren't sure there weren't any other solar system and now, just 15+ years later, we seem to have evidence there are billion others.
"To estimate the number of other worlds, Dr. Cassan and his colleagues studied 100 million stars between 3,000 and 25,000 light-years from Earth with gravitational microlensing."
And they apparently found most of them had at least one or two planets - most of them of course unsuitable for carbon-based life.
I see...
You are right.
Mark Lamm suggest this article to me and I scooped it automatically. I didn't see the complete url.
Anyway, I think that it is not so serious.
Thank you olivierc :-)
Early in December, astronomers confirmed the existence of the first known world beyond the Solar System that exists in a cozy, habitable zone around its sun-like star.It’s too soon to say whether the planet, called Kepler-22b, has a rocky, watery or gassy surface. Nevertheless, NASA used some artistic license to render the planet (below), casting it in a green-blue with wispy white clouds.Astrobiologist Abel Mendez of the University of Puerto Rico at Arecibo, who is developing new software to render scientifically accurate images of exoplanets, said NASA’s illustration misses the mark.“I think that the NASA image got the color right,” Mendez said, “but I don’t expect clouds like that. It probably will be more featureless like Uranus or Neptune and not so good for a press release.”To Mendez, it’s more than an artistic quibble. Since the Kepler telescope launched in March 2009, the space-based observatory has pinpointed a whopping 2,326 exoplanet candidates, and that number is growing by about 70 planets a month.It’s an untenable situation for space artists, whose renderings often lack the accuracy informed by current planet formation theories. More importantly, said Mendez, databases of scientifically informed portrayals of unseen exoplanets — including animations — could help make sense of direct future observations...
Nice!"A beautiful and mesmerizing series of time-lapse videos taken by astronaut Ron Garan during his last weeks aboard the International Space Station"
According to this article by The Register, NASA’s Kepler mission "has spotted the first possibility" for an habitable exoplanet. But I'm a bit confused as this is also what was reported back a few months ago here.
The good news is that the search for our new home seems to be making progress.
Imagine if every time you went for on a trip, you had to carry all the fuel required to get you to your destination and back - even if that trip was to a place far, far away, like say Mars.
Project would only be the cost of a North Sea Oil complex: $15B. And would be ready by 2020. Realistic? Optimistic?
"During the 520-day fake mission to the Red Planet, nerves were sometimes frayed."
But, in spite of that finding, the mission - which attempted at replicating the conditions of a real Mars mission by confining a team of 6 would-be astronauts in a replica spaceship - was otherwise a success.
Jealousy was triggered by uneven work distribution or unbalanced reception of messages from loved ones.
As I discovered through Google+ thanks to David D. Stanton, Ron Garan is an astronaut who started using Google+ while he was living in space on the ISS.
He took pretty amazing pictures of earth that are on his profile.
I encourage you to click through and discover them: I love this social media + space combo.
"The circular patterns within the cosmic microwave background suggest that space and time did not come into being at the Big Bang but that our universe in fact continually cycles through a series of of "aeons," according to University of Oxford theoretical physicist Roger Penrose."
Interesting theory: this would mean the Big Bang would keep repeating itself overtime.
Advances in technology have lead to the discovery of new planets outside of our Solar System, and now even new moons in our own backyard.
These moons are apparently distant from Jupiter and very tiny (1 km...). Question is whether they've been captured or formed at the same time of the giant planet.
"Engineers at NASA's Goddard Space Flight Center are working on a harpoon gun that can spear the heart of the comet, collect a sample of subsurface dirt in its tip and reel it back into the hovering craft."
Could help understand the role of comets in bringing key ingredients for life to appear on earth.
"Finding that contradicts Einstein's theory of special relativity is repeated with fine-tuned procedures and equipment."
But the search for errors is not over yet...
When I heard of the results on the first experiment, I didn't even publish them, thinking it was a joke or an error. Exciting to see how this will be explained in the next few years.
Just heard Brian Greene this afternoon on NPR: fascinating speaker. Very clear.
Made me want to look further and I discovered this great TED talk he gave explaining how string theory works and could be the unifying theory Einstein was looking for. In very clear terms.
The "fifth planet" is a hypothesized giant world that was flung out of our solar system 4 billion years ago.
Some recent simulations on how the Solar System was formed have indeed shown highly unlikely results when assuming 4 giant planets only (Jupiter, Saturn, Uranus and Neptune). But a much better outcome with a 5th planet.
Now, where is it? Somewhere wandering in the dark cold space within the Galaxy...
