The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

NASA has always strived to solve the intriguing mysteries of space. The organization's Voyager mission, launched in 1977, was also a step in that direction, according to IFL Science. The mission's ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

At the edge of our solar system, NASA’s Voyager 1 spacecraft has detected a stunning “wall of fire,” a boundary where interstellar space begins. This record 90,000°F barrier, uncovered by the Voyager ...

Over the next decade, the fields of planetary science and astrobiology will be driven by key questions that can be categorized into four broad themes: the origins of the solar system, understanding ...

The Oort cloud is traditionally thought of as a vast shell of perhaps trillions of icy objects encasing our solar system, serving as the final boundary between us and the dark reaches of interstellar ...
