Satellite Imagery to Predict Disasters
David Arnold/Bristol University
This image of a volcano in Ecuador is part of an effort from an international team of space agencies within the Committee on Earth Observation Satellites
that's using satellite data to study and predict natural disasters. Radar satellites can provide information about the horizontal movement of terrain, temperature of the ground, and changes in ash clouds around volcanic craters.
Chance Of Rain
This satellite image of an Indian village called Mawsynram captures an aerial view of the wettest place on earth, according to NASA
. Thanks to annual monsoons, the village experiences an average rainfall of about 467 inches per year.
A team of scientists engineered beating human hearts by transplanting stem cells to donor hearts, allowing them to mature in a bioreactor (pictured here) for two weeks, and then giving them a shock of electricity. This is the closest scientists have come to growing complete transplantable hearts in a lab.
Luck of the Irish
NASA shared this photo
of Ireland under the green glow of an aurora in honor of St. Patrick's Day.
South Africa from Satellite
NASA also released this satellite image
of South Africa. The Sally Ride EarthKAM aboard the International Space Station took the photo as part of the EarthKAM program
, which allows students to request images of specific locations on Earth.
