Cool. Even if it does look a bit like the MS Explorer icon. Saw the film this weekend. Recommended.

This guy is so geeky he makes Stephen Hawking look butch:
He also posed the idea of disposing of fission reactors before we use them. Make them self-contained and bury them deep, so that we tap the power, and when they get turned off, they are already gone.

"NASA Rover Finds Active and Ancient Organic Chemistry on Mars""NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory's drill." "This temporary increase in methane -- sharply up and then back down -- tells us there must be some relatively localized source," "There are many possible sources, such as interaction of water and rock." www.jpl.nasa.gov/news/news.php?feature=4413

"Voyager 1 Rides 'Tsunami Wave' in Interstellar Space""It turns out that sailing through interstellar space isn't so peaceful." "NASA's Voyager 1 spacecraft — the only object made by humans to reach interstellar space — might still be caught what scientists have described as a cosmic "tsunami wave," a shock wave that first hit the probe in February, according to new research. You can hear the eerie interstellar vibrations in a video, courtesy of NASA." www.youtube.com/watch?v=ZR51v0SR5Dc tinyurl.com/o92tuau"Glaciers on Mars Likely Helped Carve Red Planet's 'Grand Canyon' "www.space.com/28018-mars-glaciers-carved-valles-marineris.html

"Does Alien Life Thrive in Venus' Mysterious Clouds?"
"Personally, I’ve always thought that Venus gets a lot of bad press. — but just above the cloud decks of Venus, you’ll find some of the most “Earth-like” conditions in our entire solar system." "Chemically, there’s definitely some mystery lurking in those beautiful clouds. Certain molecules are found there which shouldn’t be found together. Two in particular, sulfur dioxide (SO2) and hydrogen sulfide (H2S) shouldn’t be found together — when in the same place, they react with each other. The only conclusion is that, somehow, something on Venus must be creating them, otherwise there’d be none for us to see." "Another unexpected chemical in Venus’ atmosphere is known as carbonyl sulfide (OCS). On Earth, carbonyl sulfide is so difficult to create through inorganic processes that it’s been used as an “unambiguous indicator of biological activity“. tinyurl.com/pqtdtft"Between the years 1937 to 1961, six invasions of ultra-rapid gelatine-liquifying bacteria appeared in rain-water at the Norman Lockyer Observatory, Sidmouth [England]. The initial onsets of these "invasions" occurred on average 59 ± 17 days following near-dated geomagnetic storms to Venus inferior conjunctions. The author of the report describing these events came to speculate that the bacteria, which had complete tolerance to highly toxic photographic silver salts and showed strong fluorescence in ultraviolet light, may have originated in the atmosphere of Venus and were transported to earth by the solar wind." "The Venusian atmosphere has been found to be sufficiently out of equilibrium as to require further investigation.[41] Analysis of data from the Venera, Pioneer, and Magellan missions has found the chemicals hydrogen sulfide (H2S) and sulfur dioxide (SO2) together in the upper atmosphere, as well as carbonyl sulfide (OCS). The first two gases react with each other, implying that something must produce them. In addition, carbonyl sulfide is noteworthy for being exceptionally difficult to produce through inorganic means. Furthermore, one of the early Venera probes detected large amounts of chlorine just below the Venusian cloud deck." "It has been proposed that microbes at this level could be soaking up ultraviolet light from the Sun as a source of energy, which could be a possible explanation for dark patches seen on UV images of the planet. Large, non-spherical cloud particles have also been detected in the cloud decks. Their composition is still unknown." en.wikipedia.org/wiki/Atmosphere_of_Venus#Possibility_of_life

"Rogue Star HIP 85605 on Collision Course with our Solar System""according to Bailer-Jones’ calculations, the star will pass by our Solar System at a distance of 0.04 parsecs, which is equivalent to 8,000 times the distance between the Earth and the Sun (8,000 AUs)." "The real concern is the effect that the passage of HIP 85605 could have on the Oort Cloud – the massive cloud of icy planetesimals that surrounds the Solar System. Given that it’s distance is between 20,000 and 50,000 AU from our Sun, HIP 85605 would actually move through the Oort cloud and cause serious disruption." "Many of these planetesimals could be blown off into space, but others could be sent hurtling towards Earth." tinyurl.com/q2lqw9zProxima Centauri is 4.25 light years away. HIP 85605 will come within .124 light year.

About time. Now we can find out who shot it down.
