The line that separates stars from brown dwarfs may soon be clearer thanks to new work led by Carnegie's Serge Dieterich. Published by the Astrophysical Journal, his team's findings demonstrate that brown dwarfs can be more massive than…

Scientists at Southwest Research Institute studied an unusual pair of asteroids and discovered that their existence points to an early planetary rearrangement in our solar system.

In the darkest and coldest parts of its polar regions, a team of scientists has directly observed definitive evidence of water ice on the Moon's surface.

NASA's Opportunity rover has been silent since June 10, when a planet-encircling dust storm cut off solar power for the nearly-15-year-old rover.

University of California astronomers, including three from UCLA, have resolved a mystery about the early universe and its first galaxies.

Searching for life in the vast universe is an overwhelming task, but scientists can cross one place off their list.

Scientists from Australia and the United States have helped to solve the mystery underlying Jupiter's colored bands in a new study on the interaction between atmospheres and magnetic fields.

Scientists believe the solar system was formed some 4.6 billion years ago when a cloud of gas and dust collapsed under gravity possibly triggered by a cataclysmic explosion from a nearby massive star or supernova. As this cloud collapsed,…

Forty-four planets in solar systems beyond our own have been discovered in one go, dwarfing the usual number of confirmations from extrasolar surveys, which is typically a dozen or less. The findings will improve existing models of solar…

Listening to electromagnetic waves around the Earth, converted to sound, is almost like listening to singing and chirping birds at dawn with a crackling campfire nearby.
