Graze on over to the SOHO MDI Continuum Latest Image page, then break out your (properly-filtered) equipment for a look. After a couple of very quiet years, the Sun will actually be something other than a blank disk for a while. (Hat tip to David Young of the ASKC, who notes that our PST is "just sitting here in storage" -- members can check it out for 2 weeks at a time. Another reason for locals to join.)
UPDATE: Yikes! OK, the usual instructions are -- poke around a little while you're here; I particularly encourage reading the posts listed under "Important Stuff" in the left sidebar. Feedback is welcomed via the link above; first-time e-mailers will have to batter their way through Spam Arrest.
Like, you know, this guy. But I'm not just any old blogger; on Arcturus, you get to see the needle going in:
-- was the topic of the main presentation at last night's ASKC meeting. Here's presenter Fiske Miles demonstrating the finished product (click on images for full-size [640 × 480] versions):
The materials weren't too expensive -- maybe $7000, of which $4500 was the mirror, which he bought ready to install -- but the tools were something else: a full wood shop of goodies on the order of $20k. Graze on over to FiskeMiles.com for the complete presentation.
Oh, yeah: shortly before the meeting, your humble blogger got arm-twisted into running for a seat on the ASKC board. Elections are at the next meeting, Sat 23 Jun. I'd like to buy about a million dollars' worth of TV ads, so feel free to contact me via the link at the top of the page and send bundles of unmarked twenty-dollar bills. My platform:
Hey, those are at least as realistic as most campaign promises ...
UPDATE: Greensburg is now being described as "destroyed," and FOX 4 Meteorologist Joe Lauria in KC is reporting that the 1000-pound meteorite formerly on display in Greensburg, the world's largest Pallasite, is missing.
Relief information here.
2ND UPDATE: They're not kidding. And see photos 11 and 12 for what's left of the facility that housed the meteorite.
3RD UPDATE: Roxana Hegeman of the AP reports that the meteorite has turned up.
"Amid the rubble, one of the town's most locally famous features was recovered Monday. A museum volunteer searching the site of the town's Big Well museum found a missing 1,000-pound meteorite, one of the largest of its kind. The meteorite, a type called a pallasite, is insured for $1 million."
-- is the subject of my latest offering over on Chicago Boyz. Enjoy!
The latest exoplanet being touted as "Earthlike" is yet another hot Jupiter - though "hot Neptune" might be a better phrase - that has spiraled close enough to its star to have a "surface" temperature in the range that could support liquid water. But Gliese 581 C is dramatically un-Earthlike.
It has five times Earth's mass; it is undoubtedly tidally locked, such that one side always faces its star; and that star is only 1.3% as luminous as the Sun, is substantially less enriched in "metals" (in astrophysicists' parlance, any element heavier than helium), is younger than the Sun, and is variable - thus the designation HO Librae.
What we have here is a planet quite unlike any in the Solar System, orbiting a star equally unlike the Sun, being promoted as a steppingstone to the discovery of extraterrestrial (actually extrasolar) life, in the service of securing funding for, among other things, the Terrestrial Planet Finder. There's nothing wrong with building something like the TPF, though to my mind the funding mechanism is subject to drastic improvement. But the most astonishing discoveries are being forced into a very limited range of narratives to further a limited range of research.
Because what Gliese 581 C lacks is a history remotely resembling Earth's. To quote Timothy Ferris quoting American physicist Thomas Gold (page 338 in the paperback edition), things are as they are because they were as they were. Earth swarms with life, including life recently capable of investigating other solar systems, because it has maintained - with considerable assistance from Jupiter, the Moon, tectonic plate movement, and other influences - a very rough homeostasis for billions of years, punctuated with just enough change, including extinction events of sufficient (but not oversufficient) severity, to drive the development of immense biological variety.
Gliese 581 C has none of this - and equally important, and entirely lost in the employment of this discovery in the "are we alone?" narrative, is that it has its own history, one certainly as astonishing as our own, irrespective of whether it has led to intelligent aliens, or even bacteria.
The most wondrous environments in our Solar System are those least like the planet we live on. It is past time to extend that appreciation to extrasolar planets, and refrain from immediately pigeonholing them as "Earthlike," and therefore worthy of our attention, or "not Earthlike," and therefore to be ignored.
(Readers wishing to find Gliese 581/HO Librae should read the SolStation.com page linked above, then graze over here; it's about magnitude +8.4, so it should be a binocular object.)
The Dark-Sky Site, venue for the upcoming Heart of America Star Party, is seen from an unusual viewpoint in this 1-minute, 44-second video (warning: 4.4 MB) taken, somehow, by ASKCer Dave Fox, who notes "you might want to turn down your speakers for this (it's loud)" and insists that "no planes or anything at the DSS was hurt in the filming of this movie." Play spot-the-facility, and enjoy!
-- was an event whose anniversary we must never forget.
Graze on over to Announcing the Carnival of Space for, er, the announcement of the Carnival of Space.
Read Steven A. Shaw's NYTimes op-ed, Take a Rat to Dinner, for insightful commentary on actual vs perceived risk in food safety. His final sentence ends with "... officials should be prioritizing and educating, rather than making decisions based on which YouTube videos upset people the most." I have deliberately elided it thus by way of pointing out that there's an idea with a few thousand other applications besides inspections of fast-food joints.
As noted in my much earlier installment on this topic, torrents of horrific images will be viewed unedited in the near future by vast numbers of ordinary people, thanks to ubiquitous, commoditized bandwidth. Those images will produce, for perfectly good reasons of evolutionary psychology, visceral responses; and if visceral responses are transmuted directly into political intervention, we'll have a whole different layer of risk to manage. Not only officials, but opinion leaders -- and there will still be opinion leaders, even in the decentralized polity of the blogosphere -- would serve us well by growing up a little bit.
Over to you, Dr Cline.
UPDATE: See also Jack Woodall's Disease Control by Decree for a remarkable, and deadly, mixture of official over- and underreaction taking place in various countries, most but not all of which are, whaddaya know, dictatorships. This is supposedly going to be fixed by the WHO IHR; we shall see.
