NASA's Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn's north pole.
The crucial liquid helium coolant of ESA’s Herschel space observatory ran out today, which means the end of the device that served astronomers for more than three exciting years studying the cool Universe.
Virgin Galactic's SpaceShipTwo rocket blasted off today as it took its first supersonic leap toward outer space.
The "comet of the century" is coming closer, and it could create a strange kind of meteor shower as scientists gear up to observe the phenomenon.
NASA's Cassini spacecraft has recently provided the first direct evidence of small meteors breaking into streams of rubble and bombarding Saturn's rings.
The twin deep-space exploring spacecraft Voyager 1 and 2 continue their travel where nothing from Earth has flown before, and are now on the verge of leaving our Solar System for interstellar space! This data can now be followed live online on the Voyager home page, where a gauge tracks levels of tw...
Want to see Saturn this spring? Now you'll have your chance. In the early hours of Sunday morning (April 28), the ringed planet will reach is opposition, which means that will be exactly opposite the sun in our sky.
Space debris is a growing problem, comparable to littering trash in orbit, because it has the tendency to multiplicate itself exponentially as soon as there are enough objects in space and they collide with each other. The urgent need to tackle this problem was now highlighted by the 6th European Co...
We may have some new answers when it comes to Einstein's gravity theory. A strange stellar pair, which includes a massive neutron star in orbit with a companion white dwarf star, has allowed researchers to put two competing theories of gravity to the test.
Space weather, caused by the extremely energetic dynamics of the enormous fusion fire of our Sun, can have big effects on our technological infrastructure -- mostly on satellites orbiting around Earth, but in extreme cases even on the electrical and electronical infrastructure on the planet's surfac...
Russia, we have a problem. An unmanned Russian cargo spacecraft that launched toward the International Space Station yesterday encountered a serious issue. It failed to deploy an antenna used for navigation.
Galaxies can sometimes churn out stars at a frantic pace, creating a mass of activity known as a starburst. Now, researchers have examined 20 nearby galaxies and have found that these starbursts have a significantly greater effect on their host galaxy than once thought.
