April is National Poetry Month, and I plan to post one poem per day, every day this month (If you have a favorite poem that you'd like me to share, feel free to email it to me). My poetry suggestions are starting to run dry, which means I can start posting my own favorites (but you've seen many of those already) or you can send me your favorite poems, which I probably haven't read before! Today's poem was suggested by one of the SEED editors, Erin, who writes "I have a poem suggestion for you but don't feel like you have to use it just…
esiegel | March 31, 2008 Those of you who know me know that I'm unhappy living here in Arizona. The landscape and ecosystem of the Sonoran Desert, while beautiful to many, is too dry, rocky, and devoid of life for me to enjoy living here.
After my time here, I've decided that, were it somehow offered to me, I would probably pass on the opportunity to go to Mars. And so I present to you a little game I call "Mars or Arizona," where I will show you some pictures, and you get to guess which ones are pictures of Mars and which ones are pictures of Arizona. Sound easy?
Well let's bring on the pictures, and see if you…
esiegel | March 10, 2008So in a recent column I told you all the problems with having water on Mars in recent history -- namely that the atmosphere is too thin to have supported it. But many of you have (rightly) pointed out to me that there is some evidence that there could have been water on Mars a very long time ago, and that would explain some of the major features on Mars.
But one problem that remained is this: where are the carbonate deposits at the bottoms of these so called streambeds or dried-up lakes? Well, over the weekend I got an interesting email from National Geographic Magazine about Holden Crater on…
esiegel | March 3, 2008People love to speculate that Mars was once a great place for life to form, and claim that there is plenty of evidence that there used to be oceans and rivers there. But this isn't true. People used to claim there were big Canal-like features on Mars, and used this as evidence that Mars was very wet.
It was later realized that these weren't canals, but rather geological features caused by impact craters from astroids. But more recently, people have been claiming that images like the one above are examples of dried-up riverbeds.
But this turns out not to be the case. When we take a closer…
