While orbiting the sun, NASA's STEREO-A spacecraft has taken a look back at Earth, to also find Mars and Pluto in shot.
New images confirm the presence of a dark vortex on Neptune. Though similar features were seen during the Voyager 2 flyby of NASA
A modeling paper published this week in Geophysical Research Letters offers a simple but fascinating explanation: partial freezing within a subsurface, liquid water ocean.
Earth has a new dance partner, a quasi-moon named 2016 H03.
Using the upgraded Very Large Array, astronomers have produced a detailed radio map of the upper 100 kilometers of Jupiter
Two large meteorites hitting the planet millions of years apart triggered a pair of mega-tsunamis. These gigantic waves forever scarred the Martian landscape and yielded evidence of cold, salty oceans conducive to sustaining life.
A small water jet on the icy moon spews its fiercest eruptions when the moon is farthest from the planet, but overall gas output hardly increases.
NASA's MESSENGER mission has unveiled the first global digital elevation model (DEM) of Mercury, revealing in stunning detail the topography across the entire innermost planet and paving the way for scientists to fully characterize Mercury's geologic history.
The Sun is capable of producing monstrous eruptions or "superflares" that can not only break down radio communication and power supplies, but also affect the Earth's ability to support life.
NASA gets all the glory when it comes to Martian exploration, but two other space agencies are now hoping to change that. Early next week, the European Space Agency and Roscosmos are launching the first phase of their joint ExoMars mission, a major new scientific effort with an badass goal: discovering signs of life on the Red Planet.
Earlier this month, the White House's Office of Science and Technology assembled a strange gathering: scientists, artists, engineers, and policy-makers, for a workshop designed to imagine how humanity could settle the solar system.
Astronomers have found the largest known solar system, linking together a star and what was thought to be a free-floating 'lonely planet' in orbit some 1 trillion (1 million million) kilometres away from its sun.
Curiosity is busy poking and prodding the Bagnold Dunes, learning some new tricks in the first-ever interplanetary fieldwork on a sand dune. And of course it looks absolutely stunning while doing it in this latest sand dune selfie.
For decades, Alan Stern talked about how important it was to send a spacecraft to Pluto. Those speeches, given to any audience willing to lend an ear, helped build up support for a mission to what was once classified the ninth planet, maintain support once NASA agreed to fly a mission after previous efforts foundered, and to retain interest once New Horizons was on its long cruise to Pluto.
Scientists are developing a mission concept that would send a probe flying through the plume created by the 100-odd geysers erupting from the south polar region of Saturn
