Chris LaRocco and Blair Rothstein present: It sure was BIG!! The Hubble Telescope's deepest view of the universe teaches us about the beginning INTRODUCTION We certainly know that our universe exists, however, this knowledge alone has not satisfied mankind's quest for further understanding.

The Drake equation is an equation used to estimate the number of detectable extraterrestrial civilizations in the Milky Way galaxy. It is used in the fields of exobiology and the Search for ExtraTerrestrial Intelligence (SETI). The equation was devised by Frank Drake, Emeritus Professor of Astronomy and Astrophysics at the University of California, Santa Cruz.

Stabilizing a wormhole with exotic matter In principle, a wormhole could be stabilized by threading its throat with `exotic matter'. In the stable wormhole at left, the exotic matter forms a thin spherical shell (which appears in the diagram as a circle, since the embedding diagram is a 2-dimensional representation of the 3-dimensional spatial geometry of the wormhole).

Our Sun is a normal main-sequence G2 star, one of more than 100billion stars in our galaxy. The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest).

Stars are cosmic energy engines that produce heat, light, ultraviolet rays, x-rays, and other forms of radiation. They are composed largely of gas and plasma, a superheated state of matter composed of subatomic particles. Though the most familiar star, our own sun, stands alone, about three of every four stars exist as part of a binary system containing two mutually orbiting stars.

Discover what antimatter is, where it's made, and how it is already part of our lives.

The famous Drake Equation, which proports to estimate the number of communicative civilizations in the Galaxy, was actually the agenda for the world's first SETI meeting in 1961. This plaque now graces the very wall of the room at NRAO Green Bank, WV which once held the blackboard on which the equation was first written.

R. Michael Barnett of the Lawrence Berkeley National Laboratory and Helen Quinn of the Stanford Linear Accelerator Center offer this answer, portions of which are paraphrased from their book The Charm of Strange Quarks: In 1930 Paul Dirac formulated a quantum theory for the motion of electrons in electric and magnetic fields, the first theory that correctly included Einstein's theory of special relativity in this context.

Comets - Overview A comet is an icy body that releases gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.

Short answer: no. If you've read or heard that the star Belelgeuse might explode in a few weeks or a few months - that it will temporarily add a second sun to Earth's sky and somehow also possibly prove the world will end in 2012 (to which we can only say, "huh?") - you might want to find more reliable sources.

Even though there are officially eight planets now, this website has info about the nine original planets and their moons
