Hundreds of scientists and Mars-exploration enthusiasts will convene just north of Los Angeles later this week to present, discuss and deliberate the future landing site for NASA's next Red Planet rover – Mars 2020.

NASA's Voyager 2 probe, currently on a journey toward interstellar space, has detected an increase in cosmic rays that originate outside our solar system.

Cassini's Grand Finale orbits pay off: Final dives tell the story of the previously unexplored region between Saturn and its rings

Astronomers have uncovered tantalizing evidence of what could be the first discovery of a moon orbiting a planet outside our solar system.

Engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, this week commanded the agency's Curiosity rover to switch to its second computer. The switch will enable engineers to do a detailed diagnosis of a technical issue that has prevented the rover's active computer from storing science and some key engineering data since Sept. 15.

A team of researchers have found a distant Kuiper Belt Object with an orbit that supports the theory of a distant, undiscovered large planet on the far edge of our solar system.

OSIRIS-REx searched the area around Bennu (circled in green) for any signs of dust plumes, which could present a hazard to the spacecraft, For now, the coast is clear.

NASA recently submitted to Congress a plan to revitalize and add direction to NASA’s enduring purpose.

NASA still hasn't heard from the Opportunity rover, but at least we can see it again. A new image produced by HiRISE, a high-resolution camera aboard NASA's Mars Reconnaissance Orbiter (MRO), shows a small object on the slopes of the Red Planet's Perseverance Valley. That object is Opportunity.

NASA's Cassini spacecraft has detected dust storms on Saturn's largest moon, making Titan the third Solar System body where such storms have been observed.

Just over a month into its mission, Parker Solar Probe has returned first-light data from each of its four instrument suites. These early observations – while not yet examples of the key science observations Parker Solar Probe will take closer to the Sun – show that each of the instruments is working well.

During NASA's Cassini mission's final distant encounter with Saturn's giant moon Titan, the spacecraft captured the enigmatic moon's north polar landscape of lakes and seas, which are filled with liquid methane and ethane.
