By travelling to the outer solar system, the two Voyager spacecraft allowed us to see amazing details of far-distant planets and moons.
Giant planet ejected from the solar system
(PhysOrg.com) -- Just as an expert chess player sacrifices a piece to protect the queen, the solar system may have given up a giant planet and spared the Earth, according to an article recently published in ...
Coming to a solar system near you… super-Earth!
It is our general understanding of solar system composition that planets fall into two categories: gas giants like Jupiter, Saturn, Neptune and Uranus and rocky bodies that support some type of atmosphere ...
'Trojan' asteroids in far reaches of solar system more common than previously thought
University of British Columbia astronomers have discovered the first Trojan asteroid sharing the orbit of Uranus, and believe 2011 QF99 is part of a larger-than-expected population of transient objects temporarily ...

(PhysOrg.com) -- As NASA's Voyager 2 spacecraft made the only close approach to date of our mysterious seventh planet Uranus 25 years ago, Project Scientist Ed Stone and the Voyager team gathered at NASA's ...
Mission to mysterious Uranus
Scientists want to send an orbiter and probe to the ice giant planet Uranus, but do the resources exist to support such an ambitious project?
A eulogy to Herschel
(Phys.org)—With its 2160 litres of liquid helium about to run out, the Herschel Space Observatory will, by the end of March, become just another piece of space junk.
Cassini spies the ice-giant planet Uranus
(Phys.org) —NASA's Cassini spacecraft has captured its first-ever image of the pale blue ice-giant planet Uranus in the distance beyond Saturn's rings.
Uranus auroras glimpsed from Earth
(Phys.org) -- For the first time, scientists have captured images of auroras above the giant ice planet Uranus, finding further evidence of just how peculiar a world that distant planet is. Detected by means ...
Series of bumps sent Uranus into its sideways spin
(PhysOrg.com) -- Uranuss highly tilted axis makes it something of an oddball in our Solar System. The accepted wisdom is that Uranus was knocked on its side by a single large impact, but new research ...
Research model suggests moons of some planets developed from rings
Asteroid Juno Grabs the Spotlight
(PhysOrg.com) -- Toward the end of September, the sun will turn a spotlight on the asteroid Juno, giving that bulky lump of rock a rare featured cameo in the night sky. Those who get out to a dark, unpolluted ...
