Also, I've re-arranged the navigation menu on the web site, and consolidated the (formerly) two pages for the audio and video webcasts into a single page. Let me know if I've broken anything...
...and then Starbuck shows up.
The planet is therefore too compact to be made mostly of hydrogen gas, like Jupiter, the researchers say, but not compact enough to be a rocky 'super Earth', as some had speculated. Instead, they believe it must be made mostly of an exotic form of water.Grinding ice generates Saturn moon's icy plumes
Although the parent star is much cooler than the Sun, the planet orbits 13 times closer to the star than Mercury's orbit around the Sun. That means the surface must be a blazing hot 300° C or more, keeping water in its atmosphere in vapour form.
But the high pressures in the planet's interior would compress the water so much that it would stay solid even at hundreds of degrees Celsius -- the expected temperatures inside the planet. There are a variety of exotic 'hot ice' states possible in such conditions, with names like 'Ice VII' and 'Ice X'.
"Water has more than a dozen solid states, only one of which is our familiar ice," says team member Frederic Pont of Geneva University. "Under very high pressure, water turns into other solid states denser than both ice and liquid water, just as carbon transforms into diamond under extreme pressures."
Saturn's gravity causes ice on its moon Enceladus to grind together, generating the plumes of ice crystals and water vapour seen in recent years by the Cassini spacecraft, new calculations suggest.
The findings suggest that any liquid ocean on the moon may be buried beneath an icy shell several kilometres thick, making it difficult to ever retrieve a liquid sample that could be tested for life.
PS: You know, the image and the embed lined up before I posted it. Hey brad, LJ sure worked a lot better before you stopped giving a shit...
Pay attention to the background.
PS: Thank you, LiveJournal, for completely screwing up the formatting on this post with the complementary fifty pixel border you put around the videos. That's awesome.
I shoot with a Canon EOS 5D. I shoot in the dark a lot. It's a great camera, but it doesn't auto-focus very well in low light, so I usually have a flash attached (Speedlite 580EX) and have the flash set to "emit, no fire". This means that when the camera tries to get a focus lock, the flash unit flashes a dim red light, but when I take the picture, the flash itself doesn't fire. (I don't understand how the on-camera, flashless autofocus works, but it doesn't involve emitting visible light.)
This works reasonably well. But, the flash is bulky and heavy.
Can I get a device that is, like, just the bottom inch of the flash unit? The "focus-light" part, but not the "flash" part? (Will an ST-E2 do this?)
Alternately, what's the smallest/lowest-profile flash I can use for this instead? I'd like something I can just leave attached to the camera without making it be twice as big.
Update: I guessed right, the correct answer is "ST-E2".
This is the proposal that was rejected. Google's board of directors, and a majority of their shareholders, think the following is a bad idea:
- Data that can identify individual users should not be hosted in Internet-restricting countries, where political speech can be treated as a crime by the legal system.
- The company will not engage in pro-active censorship.
- The company will use all legal means to resist demands for censorship. The company will only comply with such demands if required to do so through legally binding procedures.
- Users will be clearly informed when the company has acceded to legally binding government requests to filter or otherwise censor content that the user is trying to access.
- Users should be informed about the company's data retention practices, and the ways in which their data is shared with third parties.
- The company will document all cases where legally binding censorship requests have been complied with, and that information will be publicly available.
