Asked in Australia, Great Barrier Reef
Can you see the Great Barrier Reef from space?
Yes, the Great Barrier Reef is visible from low earth orbit. It is reported to be the only living thing visible from space with the unaided eye. It can be seen from the International Space Station and the Space Shuttle. Further out in space, such as from the moon, it is not visible. Imagery from satellites is important in determining the extent of coral bleaching occurring on the reef which is threatening the coral. This can be detected from space imagery to a depth of 10m. Maps made from these images can determine the extent and progression of the bleaching. MODIS (Moderate Resolution Imaging Spectroradiometer) images taken from space keep watch over the location of coral bleaching on the reef. NASA's Terra and Aqua satellites monitor surface temperature and color. Data from these images appears online within three hours of the satellites' orbit passing over the reef. MODIS imagery discovered that river plumes from Queensland were travelling to the outer reef. Without being able to see the reef from space, scientists had not realised the debris from land traveled so far. Space shuttle astronauts have also observed and photographed massive algal blooms on the reef which could impact the health of the reef. The reef also has massive seagrass meadows which have also been visible to the astronauts.
