gregladen | November 30, 2012I'm kidding, I'm kidding, NASA did not say that. But I do think people need to take it down a notch with this whole blaming NASA for doing their press conferences wrong. As far as I know, the Curiosity Martian Laboratory Robot recently approached a non nondescript pile of dirt, analyzed the bejesus out of it as a test of the fancy dancy instruments on board, and everything worked. The pile of dirt was not interesting but they did to that pile of dirt what would have required 3,000 feet of laboratory floor space full of expensive equipment and a dozen technicians working for two months back…
gregladen | October 10, 2012This morning, my inbox had a handful of interesting data that are totally unconnected to each other, each interesting in its own right, and together, a veritable potpourri of bloggyness. So, here goes:
First, Don Prothero at Skeptiblog has written one of those posts you want to keep handy next time you need to refer to Noah's Ark. The title of his post is "Ship of Foolishness" but I'm going to catalog it under Noah’s Ark compared to the Titanic. Here's the embedded data comparison:
I gotta get me some of that Gopher Wood.
Ok, I said these different data comparisons were not related to each…

So, you've been around a while, seen all sorts of things, and learned an awful lot about the world, solar system and Universe that we live in. But how well do you know it, really?

To scale and in order, these are the eight planets you know so well. There are the four rocky worlds of our inner solar system: Mercury, Venus, Earth, and Mars, and the four gas giants that dominate the outer solar system: Jupiter, Saturn, Uranus, and…

Back before the telescope was invented, Saturn was known as the Old Man of the Skies. The slowest-moving of the naked-eye planets, it's the only one that would reliably be in nearly the same location, year after year. You can find it all summer, after sunset, by following the "arc" of the handle of the big dipper all the way until you run into the brightest northern-hemisphere star, Arcturus, and then speeding on to the very bright Spica. Saturn is right next door.

If planets are a dime a dozen, moons are less than a penny each. There are at least 139 moons just within our own solar system. Most of these are the property of the gas giant planets beyond Mars. More than just a nice accompaniment to planets, moons may have habitats in which liquid water could ebb and flow - and possibly be a suitable home for life. Planetary physicist Dr. Paul Estrada investigates how moons around gas giants are formed -- an important…
esiegel | January 24, 2010There are plenty of examples in the music world where a cover of a song is strikingly different from the original and still interesting. Take the song You Spin Me Round, which cracked the top 5 all over Europe and North America when Dead or Alive released it. (Click for video.) 15 years later, Dope released a cover of the song in a completely different style, with an incredibly different feel. Take a listen:
It's a pretty good cover. It's interesting to listen to, it's decidedly different from the original, and it's still instantly recognizable. But by time I get to the end of the…
