The outermost reaches of our solar system are a strange place—filled with dark and icy bodies with nicknames like Sedna, Biden and The Goblin, each of which span several hundred miles across.
Early this year, the Eduard Toll set a record: laden with liquefied natural gas, the tanker was the first commercial vessel to cross the Arctic in winter without an icebreaker.
A Southwest Research Institute team using internal research funds has made several discoveries that expand the range and value of a future Pluto orbiter mission. The breakthroughs define a fuel-saving orbital tour and demonstrate ...
Carnegie's Scott Sheppard and his colleagues—Northern Arizona University's Chad Trujillo, and the University of Hawaii's David Tholen—are once again redefining our Solar System's edge. They discovered a new extremely distant ...
The solar system was formed from a protoplanetary disk consisting of gas and dust. Since the cumulative mass of all objects beyond Neptune is much smaller than expected and the bodies there mostly have inclined, eccentric ...
Bumper car-like interactions at the edges of our solar system—and not a mysterious ninth planet—may explain the dynamics of strange bodies called "detached objects," according to a new study.
The combined power of three space observatories, including NASA's Hubble Space Telescope, has helped astronomers uncover a moon orbiting the third largest dwarf planet, catalogued as 2007 OR10. The pair resides in the frigid ...
Ever since enthusiasm started growing over the possibility that there could be a ninth major planet orbiting the sun beyond Neptune, astronomers have been busy hunting it. One group is investigating four new moving objects ...
The dynamical properties of these asteroids, observed spectroscopiccally for the first time using the Gran Telescopio CANARIAS, suggest a possible common origin and give a clue to the existence of a planet beyond Pluto, the ...
(Phys.org)—A team of space scientists at the University of Michigan has discovered a dwarf planet that is approximately half the size of Pluto and twice as far from the sun. The sighting was reported by NPR, which interviewed ...
