Within days of the news reports, the university’s Earthquake Research Institute posted a lengthy disclaimer on its Web site, saying the forecast was just the opinion of two of its researchers and noting that the study had a “large margin of error.” Colleagues said the report jumped to conclusions that other earthquake experts didn’t support. “Many seismologists think this kind of study is too simple,” said Naoyuki Kato, a seismologist at the institute. The growing skepticism here about earthquake forecasts is the byproduct of Japan’s long, expensive and fruitless effort to figure out where and when the big ones will strike.
VANCOUVER, British Columbia — In 2011, Japan was one of the most prepared countries in the world for a massive earthquake.
Astronomers using NASA’s Hubble Space Telescope have found a cluster of young, blue stars encircling the first intermediate-mass black hole ever discovered. The presence of the star cluster suggests that the black hole was once at the core of a now-disintegrated dwarf galaxy. The discovery of the black hole and the star cluster has important implications for understanding the evolution of supermassive black holes and galaxies

As the crew of the final space shuttle flight prepares to return home early Thursday morning, ground teams at Mission Control in Houston is preparing to support their entry and landing at Florida’s Kennedy Space Center. Among the teams at Mission Control is the National Weather Service Spaceflight Meteorology Group (SMG), which has provided landing weather support for all 135 shuttle missions.
