Tvashtar on Io

The gorgeous plumes of Ionian volcanos rise into the sunlight on this image taken from the New Horizons spacecraft as it sped past Jupiter. The darkside of Io is seen via "Joveglow". Tvashtar and a seemingly asymmetric plume is at top.

More snow shadows

Ken commented on the appearence of snow shadows in a Pennsylvanian forest and made an interesting insight: "the snow can actually be considered a very slow acting photographic medium". Which is honestly so true. I also posted two new snow shadows from today.

The lunar eclipse

Chicago got a mostly cloudy eclipse--we never saw it fully eclipsed and only had glimpses as the Moon left the Earth's shadow. Here's a sample of what it looked like from Ryerson Observatory:

The view at Mars from Rosetta

The ESA's Rosetta spacecraft flew by Mars yesterday on its long mission to reach Comet 67P/Churyumov-Gerasimenko in 2014. As is standard, the spacecraft imaged Mars. What's ultimately so satisfying about this picture is perspective; the wholeness of the experience creating by putting a little of the spacecraft in the image. Look at the rest of the Rosetta images; none of them give you a sense of location as the special image taken by the piggyback Philae lander.

We are also only a day away from a Jupiter fly-by from the New Horizons spacecraft, speeding its way to Pluto as fast as it can, hopefully before the Pluto's atmosphere refreezes onto the surface. See where New Horizons is now.

Lunar Eclipse Saturday

The moon wheels closer to full over the week, moving ever closer to its eclipse on Saturday.

Jupiter ... from Mars

The impressiveness of the Mars Reconaissance Orbiter's instruments continues to amaze me. Geek Counterpoint has a link to a HiRISE image of Jupiter taken from Mars. See Jupiter close-up or a wide-image of Jupiter and its satellites (10MB JPG). The MRO is expected to return 3.25 terabytes of data during its mission.

More on Adult Swim and the Boston Bomb Scare: the local Chicago angle

This unidentified hoax device was found in a Hyde Park establishment where it has been hanging up for over a year, hooked up with wires to local power lines and emitting a buzzing sound. I frightfully asked an employee to turn it on. Click on the link for a short movie (AVI, 12MB).

The idiocy continues to spread

Now that the Adult Swim light board is a known, non-terroristic device, Chicago Police Superintendent Phil Cline has saved! Chicago from mass hysteria:

Speaking at a Navy Pier news conference this morning where he had several of the devices on display, Cline noted the illuminated signs—intended to promote the late-night cable TV cartoon show "Aqua Teen Hunger Force"—could have created "chaos" had they been discovered during this weekend's Super Bowl festivities.

Jumping on a bandwagon, eh?

The Boston bomb scare and hysteria

CNN report on the ad campaign for a Cartoon Network TV show that closed universities, blocked river traffic, and caused mass overreaction. Instead of deciding that we as a society have overreacted and cost ourselves millions of dollars of lost productivity, we'll blame the LED throwies. Again, we fool ourselves to think this way. Bruce Schneier will hopefully say something intelligent about it, although the powers that be certainly won't listen. What are the odds a weird device deserves a massive response? Answer: very, very low.

Google Gapminder

Via Scientific American's blog, a link into Google's Flash application of world statistics, Gapminder, accurately described as "the world's most fantastic and amazing piece of interactive infoporn you have ever laid eyes on." Enjoy the animations and the simple first-level presentation, but explore deeper and see the complexity of the tool. One of the first Flash apps worth it.

Tonight's State of the Union

CNN is reporting that:

President Bush, in Tuesday's State of the Union address, will propose a plan to cut U.S. gasoline consumption by 20 percent while bolstering inventory in the Strategic Petroleum Reserve, Republican sources say.

The president's 10-year plan to cut gasoline use includes tightening fuel economy standards on automakers and producing 35 billion gallons of renewable fuel such as ethanol by 2017, according to sources briefed on the speech.

One official said the moves would be equivalent to taking 26 million vehicles off U.S. roads.

Great, if they actually do it.
Sounds familiar, yes?

Dropping gasoline consumption by 27% for passenger cars would end all imports from the Persian Gulf--entirely removing our need for trillions in defense for our started wars in the region.

Of course, in mid-2001,

Cheney said telling Americans to do more with less is not enough. "Conservation may be a sign of personal virtue, but it is not a sufficient basis for a sound, comprehensive energy policy," he said.

Now, will they finally get CAFE standards to apply to light trucks and SUVs?
And can they avoid giving massive subsidies to companies that don't need them?
Or will they continue to push the hydrogen/fuel cell car, a technology poorly suited for mobile use?

Last year's comments.

Chinese Anti-Satellite test?

Arms Control Wonk is passing a rumor, which Aviation Week and Space Technology will also run a story on January 22nd, that the Chinese launched a missile and successfully destroyed one of their own weather satellites. Destroying a satellite in such a manner should leave a rather dangerous cloud of debris that can affect other satellites in orbit for years.

If you are looking for the orbit data, look for Fengyun 1C instead of FY-1C.

Comet McNaught

Last night it started clearing up right near sunset, and through scattered clouds I was able to see a blazing new comet, C/2006 P1 McNaught, near perihelion. A bright coma and tail was visible golden deep in the murk of the western horizon. It reminded me much of Comet Hale-Bopp, except H-B was that bright and in a dark sky--this one is only 10 degrees from the Sun.
This picture is a view through a six-inch refractor at approximately 40x, taken afocally (aka put the camera up to the eyepiece).

How to find it

New astronomical discovery or hype?

You never know from embargoed press releases--in this case, from the ESA.

The online edition of Nature will publish, on 8 January 2007, a major scientific achievement in astronomy, in which European astronomers have participated, using a space telescope with ESA participation.
