Tropical Storm Norma is the newest addition to the tropical cyclones in the Eastern Pacific and NASA's Terra satellite caught it after it developed.

New climate risk classification created to account for potential 'existential' threats
A new study evaluating models of future climate scenarios has led to the creation of the new risk categories “catastrophic” and “unknown” to characterize the range of threats posed by rapid global warming. Researchers propose that unknown risks imply existential threats to the survival of humanity.
These categories describe two low-probability but statistically significant scenarios that could play out by century’s end, in a new study by Veerabhadran Ramanathan, a distinguished professor of climate and atmospheric sciences at Scripps Institution of Oceanography at the University of California San Diego, and his former Scripps graduate student Yangyang Xu, now an assistant professor at Texas A&M University.
NASA-NOAA Satellite Spots 2 Tails of Hurricane Max
NASA-NOAA's Suomi NPP satellite captured an image of the latest tropical cyclone in the Eastern Pacific on Sept. 13 along the southwestern coast of Mexico. After Max formed as a tropical storm, it appeared to have two "tails." Max strengthened into a hurricane on Sept. 14.
Max formed as a depression on Sept. 13 around 11 a.m. EDT. It was the sixteenth tropical depression of the Eastern Pacific Ocean hurricane season. By 5 p.m. EDT it had strengthened into a tropical storm.
NASA Sees Typhoon Doksuri in the South China Sea
Typhoon Doksuri appeared well-rounded and organized on satellite imagery as it moved through the north central South China Sea toward Vietnam.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible light image of Typhoon Doksuri on Sept. 14, 2017 at 1:48 a.m. EDT (0548 UTC).Although Doksuri's eye was obscured by high clouds, the center was evident by the powerful thunderstorms that surrounded it. Doksuri's western quadrant had already spread over the east coast of Vietnam as it moved toward that country.
Investigating a big dam concrete problem
When the Mactaquac Dam opened in New Brunswick, Canada, in 1968, it was expected to have a service life of 100 years, but a chemical reaction occurring within the concrete used to build the dam has drastically shortened that timeline.
Biologist reaches into electric eel tank, comes out with equation to measure shocks
The shock from a young electric eel feels like accidentally touching a horse fence. A big one is more like getting tasered — by nine of those devices at once.
