Suspicions that shooting stars come from comet dust, transformed into fiery streaks as they hit Earth's atmosphere, have been bolstered by Europe's Rosetta space mission, scientists reported Monday.
On Nov. 12, 2014, the European Space Agency's Rosetta mission made history when its Philae lander touched down on the surface of comet 67P/Churyumov-Gerasimenko. While this exciting technical achievement gained lots of headlines, ...
Yale University astronomers have identified the first "changing look" quasar, a gleaming object in deep space that appears to have its own dimmer switch.
The dying moments of an asteroid's magnetic field have been successfully captured by researchers, in a study that offers a tantalising glimpse of what may happen to the Earth's magnetic core billions of years from now.
(Phys.org)—Thinking small has enabled an international team of scientists to gain new insight into the evolution of planetary building blocks in the early solar system.
NASA's Kepler Space Telescope, despite being hobbled by the loss of critical guidance systems, has discovered a star with three planets only slightly larger than Earth. The outermost planet orbits in the "Goldilocks" zone, ...
A British-built probe which vanished 11 years ago has been found on the surface of Mars, scientists said on Friday, solving an enduring mystery of space exploration.
Two teams of astronomers led by researchers at the University of Cambridge have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - extremely luminous ...
A study by astrophysicists at the University of Toronto suggests that exoplanets - planets outside our solar system - are more likely to have liquid water and be more habitable than we thought.
Asteroids may be a byproduct of planet formation rather than planetary building blocks, according to a recent paper in Nature.
