Blasting off into space has just gotten a little bit pricier--and by "a little bit," we mean a lot. NASA has just signed a new deal that will keep American astronauts flying on Russian spacecraft through 2017, but at a cost of $70.7 million per seat.
A new image of the space-based X-ray observatory Chandra shows the enormous cloud of hot gas resulting from the epic collision of two large, colliding galaxies. This unusually large reservoir of gas contains as much mass as 10 billion Suns, spans about 300,000 light years, and radiates at a temperat...
A small space rock slammed into one of the ISS's solar panels and created a bullet-sized hole.
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.
