Valley fever is a dangerous threat to human health – and cases are on the rise in the arid southwestern United States, as wind from increasing dust storms can transport the fungal spores that cause the disease. Valley fever is caused by the Coccidioides fungus, which grows in dirt and fields and can cause fever, rash and coughing. Using NASA resear

The Grand Canyon stuns visitors with breathtaking views every day. Between November 29 and December 2, 2013, it stunned visitors even more by not being visible. A rare meteorological event filled the canyon with an ocean of clouds. Such events are so rare that National Park Service rangers-who see the canyon every day-wait for years to see the ground-hugging fog.

The 2013 fog event was unusual because of its extent, as shown in the second image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Read more
