    Modern-day scientific Magellans and Columbus's, exploring the uncharted seas at the fringes of the Periodic Table of the Elements, have landed on one long-sought island - the fabled Island of Stability, home of a new genre of superheavy chemical elements sought for more than three decades. In a presentation at the 235th national meeting of the American Chemical Society, one of the captains of these expeditions into the unknown, described how researchers now are eying other islands on the more-distant fringes of the periodic table. "Now that it has been shown that the 'island of stability' of superheavy elements exists,...

    Scientists Find Another Huge Mini-World in Outer Solar System The most distant object ever seen orbiting the Sun is nearly as large as Pluto, expanding astronomers notions of how the solar system formed and what resides in its outskirts. The round world is currently three times farther away than Pluto from the Sun, a distance that expands even further on its 10,000-year orbit. It sits in a part of the solar system that some astronomers had thought empty. It is redder and brighter than anything astronomers have seen in the outer solar system, and scientists don't know why. The object...

It's know'n so many things that ain't so." -- A favorite quote of Richard A. Muller, by 19th century humorist Josh Billings.When you think big, as Richard A. Muller does, you're bound to create ideas now and then that are so compelling you just can't let go of them -- ideas so outlandish that mainstream scientists are equally eager to dismiss them.Muller, a physicist at University of California at Berkeley, has had...

Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2002 August 2 Comet 57P Falls to Pieces Credit: Y. Fernández, S. Sheppard, D. Jewitt (University of Hawai`i) Explanation: Comet 57P has fallen to pieces, at least 19 of them. Orbiting the Sun every 5.9 years or so this faint comet - also christened Comet 57P/du Toit-Neujmin-Delporte for its three 1941 co-discoverers - is simply 57th on the list of comets known to be periodic, beginning with Comet...
