Without krill, most of the marine animals in Antarctica would disappear. So what are they?

Krill are crustaceans, each about 5 cm long. In addition to their diet of phytoplankton, they have the ability to scrape ice-algae from the underside of ice formations. In turn, they are on the menu for hungry squid, penguins, seals and whales. In short, krill form an integral part of the Antarctic ecosystem.

Together, krill would number in the billions, yet their numbers are decreasing. Why? One reason may be the melting and loss of ice formation due to increased global temperatures. Another reason is humans' greed. Krill oil, high in omega-3 fatty acids, is packaged as health medication to maintain healthy cholesterol. How many krill are worth the lif [ ... ]

Not much of a believer in dwarf planets, but here's a cool schematic of some.

In 2006 the organization responsible for classifying celestial bodies, the International Astronomical Union, decided that a new class of objects was needed. The solar system's erratic ninth planet, Pluto, was assigned to the new “dwarf planet” category along with four other bodies, all tinier than Earth’s moon. Some astronomers expect there may be as many as 50 dwarf planets in the solar system.

Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km). Discovered in 2003, Eris orbits at an average distance of 68 AU (that is, 68 times the Earth’s distance from the sun) and takes 561.4 Earth years to circle the sun. E [ ... ]
