POPSAwesome research/ Homework resource I only found this the other day and mostly I'm clipping it for my own uses; however, it's a great resource and I thought I'd share. The site itself has pretty cool info too. 'Hope you guys like the clip.

POPSCould Jupiter wreck the solar system?
"So what's the likelihood Mercury could crash into the Earth? If it did, the asteroid that most likely wiped out the dinosaurs will seem like a drop in the ocean compared with a planet 4880 km in diameter slamming into us. There will be very little left after this wrecking ball impact. But here's the kicker: There is only a 1% chance that these gravitational instabilities of the inner Solar System are likely to cause any kind of chaos before the Sun turns into a Red Giant and swallows Mercury, Venus, Earth and Mars in 7 billion years time. So, no need to look out for death-wish Mercury quite yet… there's a very low chance that any of this will happen. But some good news for Mars; the researchers have also found that if the chaos does ensue, the Red Planet may be flung out of the Solar System, possibly escaping our expanding Sun. So, let's get those Mars colonies started! Well, within the next few billions of years anyhow…" Good stuff for the next science-fiction movie :-)

POPSBio-Earth: Are Planets Living Super-Organisms? He believes that expanding the study of life sciences to the core of our world and the depths of outer space will help us find distant relatives of our own Earth -- planets that could also sustain life. To explain why contintental plates drift on the surface of the Earth's molten mantle, Maruyama argues that continents actually have life cycles. Old, cold plates on continental fringes sink to “plate graveyards” deep in the Earth’s mantle, and then rise again, creating volcanoes fueled by three-dimensional convection movements deep below the surface.

POPS50 Billion Suns! -The Biggest Single Object in the Universe Based on this self-regulating maximum rate, scientists at the Harvard-Smithsonian Center for Astrophysics, Massachusetts, and the European Southern Observatory, Chile, have calculated an upper limit for these mega-mammoth masses. Fifty billion suns, that's 100 000 000 000 000 000 000 000 000 000 000 000 000 000 kg, otherwise known as "ridiculously stupidly big" and triple the size of the largest observed black hole, OJ 287.

POPSIs a 'Dark Force' Pushing the Universe Apart? Astronomers now recognize that the eventual fate of the universe is inextricably tied to the presence of dark energy and dark matter.The current standard model for cosmology describes a universe that is 70 percent dark energy, 25 percent dark matter, and only 5 percent normal matter.

POPSA Test of the Copernican Principle Disproving the Copernican Principle would amount to a a Copernican revolution on its own account :-) Also, certain aspects of general relativity would need a profound review. Fortunately it seems Copernicus was right after all. Or was he?
