A new study out this month suggests that Jupiter's Trojan asteroids may be more peculiar than previously thought. The Trojan asteroids are rocky objects which orbit the sun just ahead of and just behind the gas giant, in ...
Now just a year and a half from launch, the mission to explore a metal-rich asteroid will soon begin assembling and testing the spacecraft.
Early planetary migration in the solar system has been long established, and there are myriad theories that have been put forward to explain where the planets were coming from. Theories such as the Grand Tack Hypothesis an ...
Physicist Pekka Janhunen with the Finnish Meteorological Institute has developed a novel idea to colonize a place other than the Earth—and it is not the moon or Mars. Instead, Janhunen is suggesting in a paper posted on ...
As the solar system was developing, the giant planets (Jupiter and Saturn) formed very early, and as they grew, they migrated both closer to and further away from the sun to stay in gravitationally stable orbits.
A Southwest Research Institute-led team of scientists has identified a potentially new meteorite parent asteroid by studying a small shard of a meteorite that arrived on Earth a dozen years ago. The composition of a piece ...
Space manifolds form the boundaries of dynamic channels to provide fast transport to the innermost and outermost reaches of the solar system. Such features are an important element in spacecraft navigation and mission design, ...
On Dec. 6 local time (Dec. 5 in the United States), Japanese spacecraft Hayabusa2 dropped a capsule to the ground of the Australian Outback from about 120 miles (or 200 kilometers) above Earth's surface. Inside that capsule ...
In a new paper published in the journal Nature Communications Earth and Environment, researchers at the University of Rochester were able to use magnetism to determine, for the first time, when carbonaceous chondrite asteroids—asteroids ...
