NASA Assesses Strategies To 'Turn Off The Heat' In New York City
January 31 — The "heat is on" in New York City, whether it's summer or winter. This is due to a phenomenon called the urban heat island effect that causes air temperatures in New York City and other major cities to be warmer than in neighboring suburbs and rural areas. And, in a big city, warmer air temperatures can impact air quality, public health and the demand for energy. More

NASA Satellite Catches A Hurricane Transforming Itself
January 31 — Hurricanes can completely re-structure themselves inside, and that presents forecasters with great uncertainty when predicting their effects on the general population. More

Converging Satellites Unlock Hurricane Lili's Sudden Demise
January 30 — Using a fleet of NASA and other satellites as well as aircraft and other observations, scientists were able to unlock the secret of Hurricane Lili's unexpected, rapid weakening as she churned toward a Louisiana landfall in 2002. The data from multiple satellites enabled researchers to see dry air move into the storm's low levels, partially explaining why Lili weakened rapidly. More

NASA News Events At The AMS Annual Meeting
January 25 — NASA researchers will present findings and meet with media on a variety of Earth science topics at the American Meteorological Society's (AMS) 86th Annual Meeting. This meeting is Jan. 29--Feb. 3 at the Georgia World Congress Center in Atlanta. More

2005 Was The Warmest Year In A Century
January 24 — The year 2005 may have been the warmest year in a century, according to NASA scientists studying temperature data from around the world. More

NASA To Fly Into Tropical "Portal" To The Stratosphere
January 23 — NASA scientists are leading an airborne field experiment to a warm tropical locale to take a close look at a largely unexplored region of the chilly upper atmosphere. This area is critical to the recovery of the ozone layer and predicting future climate change. More

Space Probes Detect Enormous Natural Particle Accelerator
January 11 — A fleet of NASA and European Space Agency space-weather probes observed an immense jet of electrically charged particles in the solar wind between the Sun and Earth. The jet, at least 200 times as wide as the Earth, was powered by clashing magnetic fields in a process called "magnetic reconnection." More

NASA's Topex/Poseidon Oceanography Mission Ends
January 5 — The joint NASA/Centre National d'Etudes Spatiales TOPEX/Poseidon oceanography satellite ceased operations after nearly 62,000 orbits of Earth. The spacecraft lost its ability to maneuver, bringing to a close a successful 13-year mission. More
