TRUCKING THE WORLD'S LARGEST TELESCOPE MIRROR

When the Hale Telescope's 5-meter (200-inch) mirror was trucked to its final
destination atop Palomar Mountain in November 1947, it inched its way over a
winding, 258-kilometer (160-mile) route at an average speed of 15 km (9.3
miles) per hour. The two-day affair shut down roads and enthralled a nation
eager for news about the construction of the world's largest telescope.

Perhaps we've become jaded. More than a half-century later, astronomers last

monolithic telescope mirror. But no one seemed to notice....

Voyager 1, which is now about three times farther from the Sun than Neptune and
Pluto are, has sent back evidence that it may have reached the "termination
shock" in the solar wind. This is the first sign of the thin solar wind piling
up against the even thinner interstellar gas beyond. "Voyager is beginning to
explore the final frontier of the solar system," said Edward Stone, project

REFINING THE COSMIC RECIPE

Astronomers have just confirmed -- and refined -- their ever-sharper grand
picture of the universe we live in. Using three-dimensional positions of
205,443 galaxies, an international team led by Max Tegmark (University of
Pennsylvania) has reanalyzed the age, composition, and future of the cosmos. As
a side result, they also discovered the largest structure yet found anywhere.

Tegmark and his colleagues based their analysis on an early look at the second
data release from the ongoing Sloan Digital Sky Survey (SDSS)....
