POPSSolstice Moon Illusion On Wednesday night, June 18th, step outside at sunset and look around. You'll see a giant form rising in the east. At first glance it looks like the full Moon. It has craters and seas and the face of a man, but this "moon" is strangely inflated. It's huge! There's no better time to see it. The full Moon of June 18th is a "solstice moon", coming only two days before the beginning of northern summer. This is significant because the sun and full Moon are like kids on a see-saw; when one is high, the other is low. This week's high solstice sun gives us a low, horizon-hugging Moon and a strong Moon Illusion.

POPSHere Come the Asteroids "The odds that a potentially devastating space rock will hit Earth this century may be as high as one in 10. So why isn’t NASA trying harder to prevent catastrophe?" Guess it sort of puts this whole credit crisis thing in perspective, huh?

POPSMercury delivers the unexpected The first images Images from NASA's MESSENGER, an acronym for MErcury Surface Space Environment, GEochemistry and Ranging spacecraft (They seem determined to come up with smart acronyms) mission toMercury were released this week. and scientists have found it was not the planet they expected (Scientists always seem to be saying things like that) There has been a change in the magnetic field since the Mariner flybys in 1974-75, and they have no idea why. The Suns Magnetic field would no doubt do some churning considering how close Mercury is to it. In 2011 after a few more flybys, MESSENGER would have lost enough speed to slip into orbit around Mercury, and become Mercury's first artificial satellite (first satellite?)

POPSStem cells used to rebuild breasts They extracted stem cells from half the fat, then mixed the cells in with the remaining fat and injected it into the lumpectomy site. The hope is that the stem cells and other "helper cells" will keep the transplanted tissue alive.

POPSDid our Solar System once have another planet? The fiery demise of a fifth rocky planet in our Solar System might have led to a flurry of asteroid impacts that pockmarked the Moon and Earth billions of years ago. The Late Heavy Bombardment (LHB) is a relatively brief period, about 3.9 billion years ago, when wayward space projectiles heavily pelted the Moon and inner planets. Craters on the Moon better match asteroids from the Asteroid Belt, located beyond the orbit of Mars.

POPSSaturn moon looks like a sponge Pumice seems like a better description,. If it looks like a sponge and weighs like a sponge. According to wikki it had a density about half that of water so it should float
