NASA's STEREO satellite captured the first images ever of a collision between a solar "hurricane", called a coronal mass ejection (CME), and a comet on April 4, 2007. The collision caused the complete detachment of the comet's plasma tail. Comets are icy leftovers from the solar system's formation billions of years ago. They usually hang out in the cold, distant regions of the solar system, but occasionally a gravitational tug from a planet, another comet, or even a nearby star sends them into the inner solar system. Once there, the sun's heat and radiation vaporizes gas and dust from the comet, forming its tail. Comets typically have two tails, one made of dust and a fainter one made of electrically conducting gas, called plasma.For more amazing images of our star, see the Boston Globe.

Mmm ... Ramadan
Personally, I don't have the time for religion -- and I'm putting it politely here. They're all run by stupid old men, more interested in their power trip and as result, tend to fuck the world over rather than doing much good. But I'm not going to start. This post is about Ramadan. When I was young, growing up in Guyana, the best thing about Ramadan was when it was over -- because when it was over, it didn't matter if you were Muslim or not -- you got to eat -- and that's probably the only good thing about religion -- the feasts they produce. I'm salivating here.
Some of the images for the slideshow above was obtained from the Boston Globe, and others just came from random image searches.

Mad about roundabouts
I just came back from Scotland, and encountered roundabouts for the first time. After a few days, I acutally got the hang of them. Could be useful here in North America.
Souce: Picdit.
