Happy birthday to childofchaos!
Hello to new reader vash137!
Mostly shoulder/upper back tightness, mostly from spending a lot of time in the car - I'm used to stretching and shifting position all day. But we only have about an hour in the car today, and none at all tomorrow. And I am tired,m and will likely nap today.
Orphan's Tales Roadshow
If you are in or near New York, you should come out for this. It's a one-of-a-kind interstitial-arts spectacle, and tonight is The Last Show. Period. So come for story, song, art. Be amazed. South Street Seaport Museum's Melville Gallery - 213 Water St, Manhattan - New York, NY 10038, 7-10pm.
The car adapter thingie does not fit in Cat's car's cigarette lighter. Argh. So I have had scant minutes of writing time. Which is driving me crazy. Will have some time at rosefox's today.
* I love all of the stuff they're selling to support Steven Brust, but I really must have this.
* haikujaguar reviews the Kindle, and I kinda want one now.
* gwynraven is selling shiny things!
* Read my husband yendi for all of the great secret Amazon.com deals! He posts new finds almost daily. Some really great stuff. Also read him for Teh Funny.
Scientists analysing data gathered by the Cassini spacecraft have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen and methane). The observation has now been verified on 16 different encounters and findings will be published in Geophysical Research Letters on November 28.
Professor Andrew Coates, researcher at UCL’s Mullard Space Science Laboratory and lead author of the paper, says: “Cassini’s electron spectrometer has enabled us to detect negative ions which have 10,000 times the mass of hydrogen. Additional rings of carbon can build up on these ions, forming molecules called polycyclic aromatic hydrocarbons, which may act as a basis for the earliest forms of life.
“Their existence poses questions about the processes involved in atmospheric chemistry and aerosol formation and we now think it most likely that these negative ions form in the upper atmosphere before moving closer to the surface, where they probably form the mist which shrouds the planet and which has hidden its secrets from us in the past. It was this mist which stopped the Voyager mission from examining Titan more closely in 1980 and was one of the reasons that Cassini was launched.”
The new paper builds on work published in Science (May 11) where the team found smaller tholins, up to 8,000 times the mass of hydrogen, forming away from the surface of Titan.
Dr Hunter Waite of the South West Research Institute in Texas and author of the earlier study, said: “Tholins are very large, complex, organic molecules thought to include chemical precursors to life. Understanding how they form could provide valuable insight into the origin of life in the solar system."
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL.
Getting to rosefox's, showering, writing and editing til we need to haul crap over for the show.
