Calçada Chemical models developed to help limit the emission of pollutants by car engines are being used to study the atmospheres of hot exoplanets orbiting close to their stars. The results of a collaboration between French astronomers and applied combustion experts will be presented by Dr…

Tropical Cyclone Josie’s deadly flooding rainfall examined with IMERG

Tropical cyclone Josie didn't make landfall in Fiji but its heavy rainfall resulted in deadly flooding. NASA calculated the rainfall that Josie left in its wake as it moved south of Fiji and began weakening. Tropical cyclone Josie moved close to Fiji and its clockwise circulation streamed moisture over Fiji causing flooding that led to the deaths of at least four people. At NASA's Goddard…

NASA sees Tropical Cyclone Iris at Queensland coast

IMAGE: The AIRS instrument aboard NASA's Aqua satellite captured an infrared image of Tropical Cyclone Iris on April 3 at 0323 UTC (April 2 at 11:23 p.m. EDT). Coldest cloud tops... view more  Credit: Credits: NASA JPL/Heidar Thrastarson When NASA's Aqua satellite passed over Tropical Cyclone Iris near the coast of Queensland, Australia it measured cloud top temperatures and found strong storms with the potential for…

Hubble makes the first precise distance measurement to an ancient globular...

Astronomers using NASA's Hubble Space Telescope have for the first time precisely measured the distance to one of the oldest objects in the universe, a collection of stars born shortly after the big bang. This new, refined distance yardstick provides an independent estimate for the age of the universe. The new measurement also will help astronomers improve models of stellar evolution. Star clusters are the…

GPM satellite probes Tropical Cyclone Iris weakening near Australian coast

The Global Precipitation Measurement mission or GPM core satellite analyzed Tropical Cyclone Iris' heavy rainfall as it lingered near the Queensland coast. Iris has since weakened and is moving away from the coast. Tropical Cyclone Iris has taken a long, fluctuating and serpentine trek since the tropical cyclone formed in the Coral Sea northeast of Australia on March 24. For a while Iris weakened and…
