A ninth planet? Astronomer Rob Cockcroft has heard it all before.
A student-built experiment aboard NASA's Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has been integrated onto the spacecraft.
Asteroid 2003 SD220 safely flew past Earth on Dec. 24 at a distance of 6.8 million miles (11 million kilometers). Scientists at NASA's Jet Propulsion Laboratory in Pasadena, California, have generated the highest-resolution ...
Planet Earth could be at higher risk of a space rock impact than widely thought, according to astronomers who suggested Tuesday keeping a closer eye on distant giant comets.
Asteroid 1998 WT24 safely flew past Earth on Dec. 11 at a distance of about 2.6 million miles (4.2 million kilometers, 11 lunar distances). During its flyby, NASA scientists used the 230-foot (70-meter) DSS-14 antenna at ...
After a comet for Halloween, another Earthly holiday will be marked by a visit from a celestial body—this time a large asteroid zipping past on Christmas Eve, astronomers said Thursday.
Michael Daly, a York University researcher, is the lead scientist on a laser altimeter that will map the surface and create a 3D model of the asteroid Bennu during a NASA mission launching in 2016.
The final approach to an asteroid has been practised for ESA's proposed Asteroid Impact Mission using a real spacecraft camera mounted on a robot arm.
A Japanese space probe launched last year passed by Earth on Thursday to harness the planet's gravitational pull to propel it toward a far away asteroid in its quest to study the origin of the solar system, authorities said.
Was it a catastrophic collision in the star's asteroid belt? A giant impact that disrupted a nearby planet? A dusty cloud of rock and debris? A family of comets breaking apart? Or was it alien megastructures built to harvest ...
