Between 50 and 100 kilometers (30–60 miles) above the Earth's surface lies a largely unstudied stretch of the atmosphere, ...

Design could help to probe the ‘ignorosphere’, a layer of ultra-thin air that has largely escaped exploration by balloons, ...

For decades, scientists puzzled over why Uranus seemed colder than expected. Now, an international research team led by the University of Houston has solved the mystery: Uranus emits more heat than it ...

A physics phenomenon discovered 150 years ago allows tiny objects to levitate using just sunlight – and now it could enable swarms of sensors to explore part of Earth’s long-neglected upper atmosphere ...

An artist's impression of Sedna, with a hypothetical moon near it and the Sun, like a bright star, in the background (Image: NASA/JPL-Caltech). These comets are much faster at completing this orbit ...
