SpaceX's Dragon spacecraft left for the International Space Station with 5000 pounds of NASA cargo on Friday.
Scientists at NASA's Solar Dynamics Observatory (SDO) have developed a new way of probing the inner depths of the Sun by collecting data from the star's atmosphere, learning there's more to the solar surface than meets the eye.
Using the Kepler Space Telescope, astronomers made a landmark discovery: the first Earth-sized planet within the habitable zone of a star, where water could exist in liquid form.
While much of the US East coast was covered by clouds during the total lunar eclipse early Tuesday morning, the skies were unobstructed in Arizona where the National Science Foundation's National Optical Astronomy Observatory is located, providing for some excellent views of the so-called "blood moon", as well as information on the particles in the atmosphere.
About a year ago, NASA's Cassini spacecraft, which has been orbiting Saturn since 2004, took a series of images of the planet's outermost rings, documenting an unusual protuberance along the outer ring rim. Now, astronomers report that the disturbance may be the result of a newly forming Saturnian moon.
The first total lunar eclipse of the year occurred early Tuesday, treating skywatchers across the Americas to an amazing spectacle: the Earth's shadow falling across the moon, casting it in an eerie orange hue.
Years of research by the University of Basque Country Planetary Sciences Group have revealed intriguing clues about the planet's seasonal weather patterns and rotational period, according to a release from the school.
A new study shows an asteroid impact many times more powerful than the one that killed the dinosaurs probably hit the Earth about 3.2 billion years ago - a cataclysmic event that changed the world's tectonic activity, created a vast array of geological features, and contributed to a shift in evolutionary patterns.
A rare cosmic opportunity allowed astronomers to detect what may be the first signs of an exomoon - a satellite orbiting an as-of-now unknown planet beyond our solar system.
NASA's Hubble Space Telescope may be aging, but it regularly delivers images of astronomical wonders, and now its operators have come up with a novel new trick to get the telescope to measure stars at a distance up to 10 times farther than previously possible.
New research shows that Gusev Crater on Mars might have held a lake in the past.
A curious streak of light that appears to be emitted from the surface of Mars has caused a world of speculation, with some claiming it's a sign of life on Mars, and others suggesting the flare is merely a photographic glitch on one of NASA's Curiosity Mars rover's cameras.
Astronomers have measured rate of expansion of early Universe using 140,000 distant quasars. According to the research team, the current measurement of expansion is the best-ever with a precision of two percent.
Astronomers have their telescopes trained on a small gas cloud in the center of the Milky Way that's about to become the next meal of the supermassive black hole in the galaxy's core.
