European scientists at EPFL labs have designed an ultra-compact motor - dubbed MicroThrust - that will allow small satellites to journey beyond Earth's orbit using just a tenth of a liter of fuel.
Amazon founder Jeff Bezos says he's found the five engines from the Apollo 11 spacecraft, deep beneath the Atlantic, and plans to bring at least one to the surface.
Astronomers have long searched for habitable exoplanets orbiting red dwarf stars (M dwarfs), which are considered the most common type of star in the Milky Way galaxy.
US scientists have come up with new evidence that the key ingredients for life were brought to our planet by comets, billions of years ago.
Scottish engineers have come up with a new way of dealing with asteroids that threaten the Earth - firing lasers at them from a swarm of small satellites flying in formation.
We've got Jupiter to thank for the spectacular meteor showers associated with Halley's comet, says an Armagh Observatory astronomer.
Runaway planets could be hurtling through space at up to 30 million miles an hour, torn from their suns by a black hole.
Europe's launched its heaviest-ever cargo to the International Space Station, carrying food, water, air and fuel, as well as experiments and spares.
A unique, previously unseen landform could potentially provide scientists with a window into the geological history of Mars.
Scientists studying images of the giant asteroid Vesta are working to explain the existence of a number of bright spots.
Astronomers have discovered a weird rectangular galaxy within a group of 250 galaxies some 70 million light years away.
The MESSENGER spacecraft recently completed its study of the planet Mercury which it orbited for one Earth-year.
Any life on the 'super-Earth' Gliese 581-d is unlikely to make it off the planet and onto others within its solar system.
X-ray and ultraviolet observations from NASA's Swift satellite have given new infoprmation about the origins of Type Ia supernovae.
A team of US scientists has managed to formulate the first complete global geologic map of Io, the innermost of Jupiter's largest moons.
A bombardment of cosmic rays on the moon's surface could be creating complex carbon chains similar to those that form the foundations of biological life.
Some orbits are apparently more popular than others in young solar systems emerging around baby stars - which often results in "planet pileups" and "planet deserts."
The first docking of a commercial spaceship with the International Space Station could take place as early as next May.
The early Earth flipped back and forth between a hydrocarbon-free atmosphere and a hydrocarbon-rich one similar to that of Saturn's moon, Titan.
Messier 9 can best be described as a globular cluster, a roughly spherical swarm of stars that lies approximately 25,000 light-years from Earth.
