New Study of Supernovae May Absolve Einstein of His Self-Confessed "Biggest Blunder"

Robert Tindol
Based on an ongoing study of exploding stars in the distant universe, astrophysicists have concluded that the effect of the "dark energy" that is speeding up the expansion of the universe is within 10 percent of that of Albert Einstein's celebrated cosmological constant. Cosmologists regard this result as a major step forward in understanding the nature of this mysterious property of the universe.

Watson Lecture: Exploring Einstein's Legacy

Kathy Svitil
November 25 marks the 90th anniversary of Einstein's formulation of his theory of general relativity, which describes gravity as a consequence of the warping of space and time.

Cracks or Cryovolcanoes? Surface Geology Creates Clouds on Titan

Kathy Svitil
Like the little engine that could, geologic activity on the surface of Saturn's moon Titan-maybe outgassing cracks and perhaps icy cryovolcanoes-is belching puffs of methane gas into the atmosphere of the moon, creating clouds.

NASA Grant Will Fund New Research on Mars with the Spirit and Opportunity Rovers

Robert Tindol
When it comes to longevity, the Spirit and Opportunity rovers on Mars are giving some real competition to the pink bunny from those battery advertisements. The two rovers in a couple of months will celebrate their second anniversary on the red planet, even though their original missions were only 90 days.

Interdisciplinary Scientists Propose Paradigm Shift in Robotic Space Exploration

Robert Tindol
Just ask any geologist. If you're studying the history of a planet and the life forms that may have lived on it, the really good places to look are rugged terrains like canyons and other areas where water, igneous activity, wind, and seismic rumblings have left their respective marks. Flat is not so good.

Tenth Planet Has a Moon

Kathy Svitil

The newly discovered 10th planet, 2003 UB313, is looking more and more like one of the solar system's major players. It has the heft of a real planet (latest estimates put it at about 20 percent larger than Pluto), a catchy code name (Xena, after the TV warrior princess), and a Guinness Book-ish record of its own (at about 97 astronomical units-or 9 billion miles from the sun-it is the solar system's farthest detected object). And, astronomers from the California Institute of Technology and their colleagues have now discovered, it has a moon.

Most Distant Explosion in Universe Detected; Smashes Previous Record

Robert Tindol

Scientists using the NASA Swift satellite and several ground-based telescopes, including Palomar Observatory's robotic 60-inch telescope, have detected the most distant explosion yet, a gamma-ray burst from the edge of the visible universe.
