Solar Eclipse on Mars
This sort of eclipse, where the nearer body doesn’t quite cover the sun, is called an annular eclipse, after the Latin word for “ring-shaped”.
These sort of annular astronomical coincidences happen on Earth, too, since our distance from the moon changes throughout each body’s elliptical orbit. Beautiful stuff:
Curiosity is becoming quite the skywatcher. Last month it aimed its camera up and captured Mars’ two moons in one shot!
have we surrendered the moon to alien invaders?
NASA has finally answered a long-standing question: all but one of the six American flags on the Moon are still standing up. Everyone is now proudly talking about it. The only problem is that they aren’t American flags anymore. They are all white.
So America f*ck yeah, right? Not quite. While the $5.50 nylon flags are still waving on the windless orb, they are not flags of the United States of America anymore. All Moon and material experts have no doubt about it: the flags are now completely white. If you leave a flag on Earth for 43 years, it would be almost completely faded. On the Moon, with no atmospheric protection whatsoever, that process happens a lot faster. The stars and stripes disappeared from our Moon flags quite some time ago.
NASA astronaut Don Pettit recently uploaded a gallery of photos to the Johnson Space Center’s Flickr page. Pettit on how he captured these amazing images:
“My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, the ‘stack’ them using imaging software, thus producing the longer exposure.”
Ed note: Here are the Hubble Space Telescope’s finest photos.
