This photo was taken by NASA’s LDCM satellite as it floated over the Indonesia’s Paluweh volcano on April 29, 2013.
The LDCM is NASA’s eighth satellite in the Landsat series, a program is designed to send satellites around Earth to gather images of natural and human impacts on our planet. Landsat is a collaboration with the United States Geological Survey (USGS).
The satellite also has a thermal infrared sensor that can measure changes and differences in heat typically not visible to human eyes. The bright white dot indicates a hot spot surrounded by colder, darker ash clouds, writes NASA.
