An impressive solar flare is heading toward Earth and could disrupt power grids, GPS and airplane flights....

Physicists investigating the make-up of the universe said on Wednesday they were closing in on the long-sought but elusive Higgs boson they believe was key to turning debris from the Big Bang into stars, planets and finally life.

The tidy Swiss want to clean up space. Swiss scientists said Wednesday they plan to launch a "janitor satellite" specially designed to get rid of space junk, the orbiting debris that can do serious and costly damage to valuable satellites or even manned space ships.

A pair of Earth-size worlds orbiting a dying star may be the fractured remnants of a single Jupiter-like gas giant, a new study says.

After more than two decades of drilling in Antarctica, Russian scientists have reached the surface of a gigantic freshwater lake hidden under miles of ice for some 20 million years — a lake that may hold life from the distant past and clues to the search for life on other planets.

A glimpse beyond our solar system reveals the neighborhood just outside the sun's influence is different and stranger than expected, scientists reported Tuesday....

Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colo., released a study claiming that inconsistencies between satellite observations of Earth's heat and measurements of ocean heating amounted to evidence of "missing energy" in the planet's system.

A huge sunspot unleashed a blob of charged plasma Thursday that space weather watchers predict will blast past the Earth on Sunday. Satellite operators and power companies are keeping a close eye on the incoming cloud, which could distort the Earth’s magnetic field and disrupt radio communications, especially at higher latitudes.

Scientists are confirming a recent and rare invasion from Mars: meteorite chunks from the red planet that fell in Morocco last July. This is only the fifth time scientists have chemically confirmed Martian meteorites that people witnessed falling. The small rock refugees were seen in a fireball in the sky six months ago, but they weren't discovered on the ground in North Africa until the end of December.

The failed Russian space probe Phobos-Grunt fell back to Earth on Sunday, crashing in the southeastern Pacific Ocean off Chile, Russia's state news agency Itar-Tass announced.
