Astronomers have discovered evidence for the most massive black holes yet identified, an observation that could help write the history of galaxy formation and evolution over the universe's 13.7 billion-year history.
The federal government's annual Arctic report card reinforces the direct and indirect effects that global warming are having on one of the world's most sensitive ecosystems.
Once the Red Sox missed out on the postseason with a memorable collapse, the team's free agents are on their way out, marking a big offseason shakeup.
A Russian space craft loaded with toxic fuel in its tanks and headed for a Mars moon has yet to leave Earth's orbit. Russian engineers say it looks increasingly likely to tumble back to Earth.
A team of astronomers has uncovered a population of dwarf galaxies some 9 billion to 10 billion light-years away that were producing stars at a furious pace.
Astronomers using the Hubble Space Telescope have captured light from the disk of dust and gas feeding a supermassive black hole at the heart of a quasar.
Several studies in the US and overseas have found evidence that fracking and other techniques for injecting fluids into oil and gas formations have triggered small quakes, with varying degrees of certainty.
The asteroid's closest approach will be at 2:28 p.m., AST, on Tuesday. The asteroid will be roughly 203,000 miles from Earth, just inside the moon's orbital distance.
A 300-square-mile portion of the Pine Island Glacier is expected to break off in the next few months, creating a massive Antarctic iceberg. The glacier is contributing the sea-level rise.
Has the Martian climate ever been sufficiently warm to allow water to accumulate on its surface in order for life to emerge?
Is it the end of the world as we know it? A California minister predicts The Rapture begins May 21. Scientists, for their part, consider the sun's "habitable zone" in calculating when Earth will become toast.
Space shuttle Discovery taxied to a stop at Kennedy Space Center just before noon Wednesday, ending a triumphant 13-day mission and 27-year career.
Hawaii's Kilauea volcano saw "quite an exciting development" over the weekend: the lava lake at Pu'u 'O'o drained as fountaining lava burst out of new fissures on Kilauea's eastern flank.
Post-Columbia inspection methods show that foam seen tumbling along Discovery's tiles and apparently hitting twice -- caused only cosmetic damage, say NASA engineers.
Authors say a study that looked at the rise in extreme rain and snowfall in the Northern Hemisphere in the last half of the 20th century is the first to show a link to global warming.
