Full-color displays normally require separate red, green and blue light emitters. A team from the University of Osaka and Ritsumeikan University has demonstrated another approach: a single light-emitting layer that produces several colors when electrically powered at room temperature. The study...
A spacecraft meant to push NASA’s Swift Observatory to a higher orbit malfunctioned and started tumbling several days ago. Engineers think it can still succeed.
Our DNA is under constant threat. Chemicals, radiation and the everyday errors of cell division all damage it, and if left unrepaired, this can lead to diseases such as cancer. Cells invest heavily in finding and fixing these errors.
In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Because of their small sizes and locations, these satellites have been difficult to study from Earth. Now, using NASA's James Webb Space Telescope ...
On July 30, 1610, the famous astronomer Galileo Galilei became the first to observe rings around the planet Saturn. Here's why it matters centuries later.
Researchers used NASA satellite imagery, along with ground observations, to track changes in the diets of penguins on Antarctica's Danger Islands.
