Earth-orbiting satellites have spotted the wildfires ripping through Northern California.
As record-high temperatures hit the U.S. West Coast this past week, wildfires began to spread rapidly in a region west of Sacramento, quickly growing to encompass 124,000 acres (50,000 hectares), according to the New York Times. As the fires rage on, they are being monitored by Earth-orbiting satellites and experiments onboard the International Space Station.
On Tuesday (Aug. 18), California Gov. Gavin Newsom declared a state of emergency due to the fires, which have so far forced tens of thousands of evacuations, according to a statement from NASA. One part of Northern California has so many fires caused by lightning from summer storms that the region is now known as the LNU Lightning Complex.
On Wednesday (Aug. 19), NASA's Terra satellite caught sight of billowing smoke clouds spilling off of the California coast. Hot and dry conditions expected to extend across the state throughout the weekend (at least) could support continued fires and even additional wildfire outbreaks, according to the same NASA statement.
In order to fully assess conditions in California as they evolve, NASA uses its Earth Observing System Data and Information System Worldview application. With this system, the agency can analyze the high-resolution images captured by satellites like Terra.

The U.S. National Oceanic and Atmospheric Administration's (NOAA) GOES-17 weather satellite spotted the fires as well. In a GIF shared by NOAA on Twitter, you can see smoke from the fires blowing for hundreds of miles across the Pacific Ocean.
European spacecraft are also watching the fires blaze from space. For example, the Copernicus Sentinel-3 satellite, which is operated by the European Space Agency (ESA) and the European Organization for the Exploitation of Meteorological Satellites, has taken images that show the massive quantities of smoke trailing off the California coast.
As can be seen in the high-resolution image taken by Sentinel-3, the wildfires stretch across the state. In fact, according to the ESA, there are about 40 separate wildfires currently raging throughout California.
