...however, as Rudnick readily acknowledges. The uncertainty comes from the fact that his discovery is circumstantial. What he and his colleagues actually found was that there's a surprising scarcity of radio galaxies - galaxies that put out unusual amounts of radio energy - in a part of the sky marked by the constellation Eridanus. That seemed odd, since radio galaxies tend to be spread about pretty evenly. Then they took a look at an entirely different set of data: microwaves emitted shortly after the Big Bang, as seen by the WMAP (or, NASA's Wilkinson Microwave Anisotopy Probe) satellite. There...
That could hardly be a coincidence, Rudnick thought, and the simplest solution was a great void in space. That would explain why there weren't many radio galaxies in that part of the sky. And microwaves crossing a huge void would lose some of their energy, in a complex process involving the reduced gravity inside. The exciting part is that the void is so huge that current theory simply can't explain it - and astronomers just love this kind of challenge...
...world's oldest rock star is coming to Houston. Starting Aug. 31, the 3.18 million-year-old hominid skeleton known as Lucy (so dubbed because researchers were blaring the Beatles' Lucy in the Sky with Diamonds the night of her discovery) will headline the Houston Museum of Natural Science's (HMNS) new exhibit, "Lucy's Legacy: The Hidden Treasures of Ethiopia" - only her third public appearance in nearly 30 years, and the kick-off to a planned six-year nationwide tour. But while HMNS curators celebrate Lucy's arrival, some famed paleontologists are grumbling that the rare opportunity simply...
...eyes. As I explored Canal Street, I saw three monstrous pipes on the edge of the road and heard the deep rumble from the pumping station. I recalled that New Orleans is 20 feet (6 meters) or so below sea level. As I looked up at the clear sunny sky, I realized that New Orleans was a disaster waiting to happen. If it took that amount of pumping on a sunny day to keep the city dry, what would happen when the ?water overflowed the levees? I love this city and think the Federal Government should pay to relocate...
...spend your time looking at a mural. There are over 2,500 murals throughout the city--more than in any other place in the world. On South 47th Street, a lush mural shows a row-house scene in the foreground with Van Gogh's Starry Night--inspired sky as a backdrop. Gigantic, stunning portraits of Dr. J and Malcolm X grace other buildings. Prince Charles visited the mural on 40th and Pennsgrove in January to see the outsize rendering of a girl reading a book that has a brilliant column of butterflies streaming...
