August's total solar eclipse won’t be the last time the moon cloaks the sun’s light. From now to 2040, for example, skywatchers around the globe can witness 15 such events.
Their predicted paths aren’t random scribbles. Solar eclipses occur in what’s called a Saros cycle — a period that lasts about 18 years, 11 days and eight hours, and is governed by the moon’s orbit. (Lunar eclipses...

The Science Life
Only a lucky few have watched a solar eclipse from above the Earth. Angela Des Jardins wants to bring that view to everyone.
On August 21, Des Jardins, an astrophysicist at Montana State University in Bozeman, will help broadcast the first livestream of a total solar eclipse from the edge of space. She and more than 50 groups across the United States will launch high-altitude balloons to...
In July of 1972, NASA launched the first Landsat satellite into orbit around Earth. Since then, the spacecraft and its successors have transformed our understanding of Antarctica (and the rest of the planet, too). In the first year following the launch, Landsat’s images of the faraway continent showed “uncharted mountain ranges, vast ice movements and errors in maps as little as two...07/26/2017 - 13:15 Earth, Science & Society

In “Hominid roots may go back to Europe” (SN: 6/24/17, p. 9), Bruce Bower reported that the teeth of Graecopithecus, a chimp-sized primate that lived in southeastern Europe 7 million years ago, suggest it was a member of the human evolutionary family.
