This past summer Canada has been plagued with huge forest fires that have spanned most of the provinces.  British Columbia has been particularly hard hit with large portions of the landscape being decimated by fire.  In these satellite images taken by the NASA'S Aqua satellite, both the natural color and false color burn scars of left by fires can be seen.  In the natural color image it is difficult to make out the burn scars.  The false color easily identifies areas where fire has left a scar showing a brownish-red color. Currently there are 745 wildfires larger than 0.01 hectares and all wildfires of note (active or out) in British Columbia as of today, Sept. 29. (Wildfire link updates daily).  NASA's Aqua satellite collected this natural-color image with the Moderate Resolution Imaging Spectroradiometer, MODIS, instrument on September 27, 2017. 

NASA and NOAA satellite imagery show Hurricane Lee has been on a weakening trend as wind shear is battering the storm. The National Hurricane Center expects Lee to weaken quickly and its remnants to bring gusty winds to Ireland and the United Kingdom over the weekend of Sept. 30 and Oct. 1.

Tropical forests have long been considered one of the world’s most important tools in combating climate change, their fast-growing trees and rich soils sucking millions of tons of carbon out of the atmosphere every year. But a new study says these forests have switched from being carbon sinks to sources of carbon, releasing an estimated 425 million tons of CO2 each year, more than the annual emissions from U.S. cars and trucks combined.

Researchers have observed and characterized a weather process that was not previously known to occur in Antarctica's coastal regions. It turns out that the katabatic winds that blow from the interior to the margins of the continent reduce the amount of precipitation (mainly snowfall) -- which is a key factor in the formation of the ice cap. By forming a very dry layer of air in the first kilometer or so of atmosphere, the winds turn the falling snowflakes during their fall directly from their solid state into water vapor in a process known as sublimation.

When a magnitude 9 earthquake shook the western Pacific Ocean floor and sent a tsunami crashing into Japan in 2011, millions of pieces of debris — from docks and fishing boats to plastic pollution — were swept out to sea. Now, a new studyfinds that nearly 300 species hitchhiked aboard that debris across the Pacific and were scattered along the west coast of North America.

Hurricane Lee began weakening as NASA's Aqua satellite passed overhead and collected temperature information. Satellite data showed that Lee's strongest side was south of its center.

As NASA looks to explore deeper into our solar system, one of the key areas of interest is studying worlds that can help researchers better understand our solar system and the universe around us. One of the next destinations in this knowledge-gathering campaign is a rare world called Psyche, located in the asteroid belt.

NASA and NOAA satellites provided information and imagery to forecasters that showed Hurricane Maria weakened to a tropical storm on Sept. 28.

A NASA-produced map showing areas of eastern Puerto Rico that were likely damaged by Hurricane Maria has been provided to responding agencies, including the Federal Emergency Management Agency (FEMA). The hurricane, a Category 4 storm at landfall on Puerto Rico on Sept. 20, caused widespread damage and numerous casualties on the Caribbean island, an unincorporated U.S. territory with a population of about 3.4 million.

A new study appearing this week in Science reports the discovery of a startling new role of plastic marine debris -- the transport of non-native species in the world's oceans.
