NASA Sees Typhoon Pakhar Headed for Vietnam Landfall

The first typhoon of the northern hemisphere 2012 typhoon season is headed for landfall in Vietnam. NASA's Aqua and TRMM satellites have been providing forecasters with valuable data on Typhoon Pakhar, that includes rainfall rates, cloud extent and temperature.

High Water along the Isaac River

The Fitzroy River flows through eastern Queensland and empties into the ocean near the city of Rockhampton. One of the Fitzroy's tributaries is the Isaac River, which is itself fed by impermanent rivers to the north. Heavy rains swelled the Isaac River substantially in late March 2012. The Moderate ...

Volcanic Plumbing Exposed

International teams of researchers, led by the University of Leeds, studied the location and behaviour of magma chambers on the Earth's mid-ocean ridge system - a vast chain of volcanoes along which the Earth forms new crust.

NASA's TRMM Satellite Sees Newborn Tropical Storm Pakhar's Heavy Rain

System 96W intensified overnight and became Tropical Storm Pakhar during the morning hours on March 29. NASA's TRMM satellite measured rainfall rates within the storm, and noticed areas of heavy rain west of the center as the storm continued to strengthen.

Data Mining Deep Space

Bahram Mobasher, a professor of physics and astronomy at the University of California, Riverside, has received a two-year $200,000 grant from NASA to compile into a data bank all the imaging observations of galaxy surveys that the Hubble Space Telescope has performed since 2002, when a powerful imag...

Clocking an Accelerating Universe: First Results from BOSS

Some six billion light years ago, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the matter it contained, the universe had been expanding ever more slowly. Then, as matter spread out an...

Much Faster Than a Speeding Bullet, Planets and Stars Escape the Milky Way

Idan Ginsburg, a graduate student in Dartmouth's Department of Physics and Astronomy, studies some of the fastest moving objects in the cosmos. When stars and their orbiting plants wander too close to the supermassive black hole at the center of the Milky Way, their encounter with the black hole's g...

Titanium Paternity Test Fingers Earth as Moon's Sole Parent

A new chemical analysis of lunar material collected by Apollo astronauts in the 1970s conflicts with the widely held theory that a giant collision between Earth and a Mars-sized object gave birth to the moon 4.5 billion years ago.

New Seismic Hazard Assessment for Central America

A new study evaluates the seismic hazards for the entire Central America, including specific assessments for six capital cities, with the greatest hazard expected for Guatemala City and San Salvador, followed by Managua and San JosÃ©, and notably lower in Tegucigalpa and PanamÃ¡ City.

A Star Explodes and Turns Inside Out

A new X-ray study of the remains of an exploded star indicates that the supernova that disrupted the massive star may have turned it inside out in the process. Using very long observations of Cassiopeia A (or Cas A), a team of scientists has mapped the distribution elements in the supernova remnant ...
