Submission + - Voyager 1 Exits Our Solar System (telegraph.co.uk)

eldavojohn writes: The first man-made craft to do so is now entering a 'cosmic purgatory' between solar systems and entering an interstellar space of the Milky Way Galaxy. With much anticipation, Voyager 1 is now 'in a stagnation region in the outermost layer of the bubble around our solar system. Voyager is showing that what is outside is pushing back.' After three decades the spacecraft is still operating and apparently has enough power and fuel to continue to do so until 2020. The first big piece of news? "We've been using the flow of energetic charged particles at Voyager 1 as a kind of wind sock to estimate the solar wind velocity. We've found that the wind speeds are low in this region and gust erratically. For the first time, the wind even blows back at us. We are evidently traveling in completely new territory. Scientists had suggested previously that there might be a stagnation layer, but we weren't sure it existed until now." This process could take months to years to completely leave the outer shell but already scientists are receiving valuable information.

Comment Simple chemistry (Score 1) 695

http://physics.ucsd.edu/do-the-math/2011/08/recipe-for-climate-change/ Most of us should have taken at least a basic chemistry class at one point. It's pretty obvious that the amount of fuel we burn on an annual basis produces a lot of CO2 as a byproduct. It seems rather naive to me to think that adding that much of ANY compound to the atmosphere will have no effect at all.

I tend towards doubting the "science" of the Breathalyzers used also. One of my friend was stopped recently and the cop told him that if he was chewing mint gum, spit it out and wait a bit because it could increase the alcohol reading by up to 0.02%. That's a HUGE margin of error for determining whether or not to give a guy a $6000 fine.

Well in my case they certainly did. The password I had been using was "very secure", or whatever their highest rating of them is called, and somehow they got in to my account to send messages. I saw server bounce messages popping up on emails written in Spanish, so I was fairly certain they weren't coming from me. This was around Jan/Feb though, and from TFA:

The New York Times reported Monday that Google's centralized login system, code-named Gaia, was compromised by hackers in late December.

Comment Re:Underground methane leaking? (Score 4, Informative) 297

There are recent studies showing it may be possible that some of our methane on Earth is being created by the high pressure/temp conditions in the earth's mantle, rather than exclusively by the decay of organic matter. A written article on this, or an NPR segment (about 1/3 of the way into the audio file).

Sharp Rise In Jailing of Online Journalists; Iran May Just Kill Them 233

bckspc writes "The Committee to Protect Journalists has published their annual census of journalists in prison. Of the 136 reporters in prison around the world on December 1, 'At least 68 bloggers, Web-based reporters, and online editors are imprisoned, constituting half of all journalists now in jail.' Print was next with 51 cases. Also, 'Freelancers now make up nearly 45 percent of all journalists jailed worldwide, a dramatic recent increase that reflects the evolution of the global news business.' China, Iran, Cuba, Eritrea, and Burma were the top 5 jailers of journalists." rmdstudio writes, too, with word that after the last few days' protest there, largely organized online, the government of Iran is considering the death penalty for bloggers and webmasters whose reports offend it.
