NASA has released a series of Earth images entitled Blue Marble Next Generation, which includes maps of the entire earth rendered without clouds in each f the 12 months of the year and resolutions of 2km per pixel. Very nice.

Gutenberg Gem: Half-hours with the Telescope by Richard A. Proctor

September 30, 2005 | Astronomy, Gutenberg Gems | By: Mark VandeWettering

Today’s Gutenberg Gem is a neat little astronomy book, published in 1873 by Richard A. Proctor. It lists a number of half hour tours of the sky, each highlighting either a set of constellations or planets. It’s pretty brief, and certainly better modern guides exist, but it’s still a neat little thing to peruse through, […]

Eggs Stand on End at the Autumnal Equinox

September 22, 2005 | Astronomy | By: Mark VandeWettering

Well, it’s hardly surprising, given that you can (with a little effort) stand them on end pretty much every day of the year. But today’s Astronomy Picture of the Day features Bad Astronomy’s Phil Plait demonstrating that egg stability seems to be unphased by changes in the seasons. Still, today marks the beginning of fall.

Shane Ross on Dynamics, Control & Computation

August 15, 2005 | Astronomy | By: Mark VandeWettering

In a thread on Slashdot on calculating spacecraft trajectories to Mars some helpful individual pointed at Shane Ross’ Dynamics, Control & Computation page. Lots of good information on celestial mechanics.

The Tears of Saint Lawrence

August 11, 2005 | Astronomy | By: Mark VandeWettering

This weekend marks the annual return of the Tears of Saint Lawrence: better known to those of us in the amateur astronomy community as the Perseid Meteor shower. If you haven’t trekked out somewhere dark recently to gaze at the annual shower, try reading Sky and Telescope magazine’s coverage. The sky will be moonless, so […]

Deep Impact, the Movie

Check out this movie of the impactor as viewed from the flyby spacecraft. Cool.

No Dinosaurs Left on Tempel 1

July 4, 2005 | Astronomy | By: Mark VandeWettering

Tonight the Deep Impact space probe impacted Comet Tempel 1. I’m watching the coverage life on NASA TV. We can expect to see a photo from the flyby space craft to be all over the front pages tomorrow. Congratulations to all those rocket scientists. Cool stuff.

Tutorial on Deconvolution

By way of (gasp!) a useful Slashdot comment, here is a tutorial on deconvolution produced by the NRAO. What can I say? I read stuff like this for fun.

Moon-Watching Mars Rover Catches Deimos Crossing the Sun

March 23, 2005 | Astronomy, Science | By: Mark VandeWettering

Space.com reports that the Spirit rover caught these photos of Mars’ moon Deimos crossing the solar disk: in other words, a Martian solar eclipse. Very cool. You can get a version of the loop here as an mpeg or here as an animated gif. Compare these to my crude transit of Mercury that I recorded […]

Porter Garden Telescope

February 17, 2005 | Astronomy, Science | By: Mark VandeWettering

Want to own a tiny bit of telescope making history? Check out the Porter Garden Telescope, which according to an email from the owner will be up for sale shortly. There is one currently on display at the Chabot Science Center as well, in case you don’t have the means to pick one up. It […]

Iron/Nickel Meteorite Found

January 19, 2005 | Astronomy, Science | By: Mark VandeWettering

In itself, meteorites are not uncommon, but what’s pretty cool is that the Mars rover Opportunity managed to land close to a basketball sized one lying on the surface of Mars. You can read more in NASA’s press release. CMU developed a project to find meteorites in Antartica using an autonomous robot that could search […]

Webcam Images From Titan

January 14, 2005 | Astronomy, Science | By: Mark VandeWettering

The ESA/JPL has released the tiny image you see to the right and provided us with some background, but this image is as big as it gets: you can’t seem to find a higher resolution image anywhere online. Sigh. Do they only have a camera phone onboard?

Huygens Down Safe, Pictures To Come Here

January 14, 2005 | Astronomy, Science | By: Mark VandeWettering

The ESA is reporting that the Huygens lander survived it’s descent to Titan, and is transmitting data. According to JPL, the first images should be received around 11:45 PST. Kick ass! As soon as pictures are available, I’ll link ’em up here. Update: In what quite possibly have been the singularly most dull and boring […]
