Scientists have now found evidence that our Earth's oceans were created not when asteroids slammed into the planet, but far earlier.
A newly discovered planet apparently won't stick to a schedule. Astronomers have spotted a low-mass, low-density planet that's so inconsistent that automated computer algorithms have trouble picking it up as they search for stellar light curves.
Just in time for Halloween, NASA's Hubble Space Telescope has captured the ghostly glow of stars ejected from ancient galaxies that were ripped apart several billion years ago.
Astronomers may have learned a little bit more about the evolution of our universe. Scientists have found that galaxies may have settled into their current form about two billion years earlier than previously expected.
Scientists are learning more about the mysteries of space by recreating some interesting interactions in the lab. By using high-intensity lasers, scientists have mimicked the cosmic explosions that occur in the depths of space.
Can you imagine flying through space with a laser-powered rocket? It seems like something more about of science fiction than reality, right? Yet a new method for improving the thrust generated by laser-propulsion systems could bring laser-powered rockets closer to reality.
Scientists are learning a bit more about how planets form. Using the Atacama Large Millimeter/submillimeter Array (ALMA), they've detected a streamer of dust and gas flowing from a massive outer disk toward the inner reaches of a binary star system.
The sun's activity is ramping up, and now NASA's Solar Dynamics Observatory (SDO) has captured some of the images of solar flares.
NASA scientists have uncovered a starting new find on Saturn's moon, Titan. They've found an unexpected high-altitude methane ice cloud, similar to exotic clouds formed high above Earth's own poles.
On Thursday, Oct. 23, the moon passed between the Earth and the sun, causing a solar eclipse. Now, scientists have released an image of a "ring of fire" that captures this particular eclipse at its most stunning.
A pulsating star that appears to shine with the energy of 10 million stars may just be one of many in space.
