The Universe is always surprising us with how little we know about... the Universe. It's continuously presenting us with stuff we never imagined, or even thought possible. The search for extrasolar planets is a great example. Since we started, astronomers have turned up over a thousand

Supermassive Black Holes: 10 Astounding Facts
Find out what astronomers have been learning when they look deep into the core of giant galaxies. In nearly every one, they are turning up supermassive black holes that are tearing space to shreds, blasting away at their environments, and raging against the relentless force of gravity that

In this video, Fermilab's Dr. Don Lincoln describes the principle of supersymmetry in an easy-to-understand way. A theory is supersymmetric if it treats forces and matter on an equal footing. While supersymmetry is an unproven idea, it is popular with particle physics researchers as a po

Fermilab's Dr. Don Lincoln explains some of the reasons that physicists are so interested in supersymmetry. Supersymmetry can explain the low mass of the Higgs boson, provide a source of dark matter, and make it more likely that the known subatomic forces are really different facets of a

Super Earths: 10 Major Discoveries
A Super Earth is a planet smaller than Neptune, but larger than Earth. There are no Super Earths in our solar system. But they may be the most common type of planet in our galaxy, according to data from the Kepler Space Telescope. Some have rock or ice cores wrapped in hydrogen and helium

AWESOME SUPERCONDUCTOR LEVITATION!!!
A quantum levitator it's a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics. The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of fo
