The field for NASA's next New Frontiers mission is narrowing. Officials announced the two finalists for a new robotic explorer mission—one that would send a spacecraft to bring samples of the comet 67P/Churyumov-Gerasimenko ...
For many years some astronomers, working under the assumption that the Star of Bethlehem was in fact an actual celestial object, have suggested possible astrophysical explanations.
A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current position, before migrating to ...
A new study led by a University of Bristol earth scientist has shown that recently reported unexpected behaviour on Titan, the largest moon of Saturn, is due to its unique atmospheric chemistry.
The discovery of a planet with a highly elliptical orbit around an ancient star could help us understand more about how planetary systems form and evolve over time.
As a young scientist, Tony del Genio of NASA's Goddard Institute for Space Studies in New York City met Clyde Tombaugh, the discoverer of Pluto.
Space may seem empty, but it's actually a dynamic place populated with near-invisible matter, and dominated by forces, in particular those created by magnetic fields. Magnetospheres—the magnetic fields around most planets—exist ...
The space race between the USA and Russia started with a beep from the Sputnik satellite exactly 60 years ago (October 4, 1957) and ended with a handshake in space just 18 years later. The handshake was the start of many ...
A group of scientists from Queen's University Belfast and the Max Planck Institute for solar system Research in Germany have turned exoplanet-hunting on its head, in a study that instead looks at how an alien observer might ...
Ten spacecraft, from ESA's Venus Express to NASA's Voyager-2, felt the effect of a solar eruption as it washed through the solar system while three other satellites watched, providing a unique perspective on this space weather ...
