In a slow moving universe, asteroids give us a rare chance to see things moving in real time. We have such a chance coming right up on the evening of Tuesday, January 18, when 1.1-kilometer asteroid (7482) 1994 PC1 passes ...
Object 90377 Sedna—a distant trans-Neptunian object known best for its highly elliptical, 11,390-year long orbit—is currently on its way toward perihelion (its closest approach to the sun) in 2076. After that, Sedna will ...
Astronomers have managed to link the properties of the inner planets of our solar system with our cosmic history: with the emergence of ring structures in the swirling disk of gas and dust in which these planets were formed. ...
Just two weeks after launching from Vandenberg Space Force Base in California, NASA's Double Asteroid Redirection Test (DART) spacecraft has opened its "eye" and returned its first images from space—a major operational ...
Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of researchers led by the ...
Launching in August 2022 and arriving at the asteroid belt in 2026, NASA's Psyche spacecraft will orbit a world we can barely pinpoint from Earth and have never visited.
A massive asteroid will whiz past the Earth on Saturday, but hold any thoughts of disaster movies.
Dozens of space-based telescopes operate near Earth and provide incredible images of the universe. But imagine a telescope far away in the outer solar system, 10 or even 100 times farther from the sun than Earth. The ability ...
From Mercury to the depths of the distant Kuiper Belt, there aren't many unexplored corners of the solar system out there. One class of object, however, remains to be visited: the transitional Centaurs out beyond the orbit ...
Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the Earth and moon are thought to be products of this type ...
