Mars may be helping to shape the surface of some near-Earth asteroids, according to a new study published in the journal Icarus.
A European Space Agency-led team of astronomers has determined the rapid space weathering seen on asteroid surfaces is most likely caused by the solar wind. The study led by ESA scientist Pierre Vernazza reveals that solar wind ages and reddens asteroid surfaces much more quickly than previously thought -- in less than a million years.
In research that could aid decisions about future asteroids on a collision course with Earth, MIT scientists have for the first time determined the composition of a near-Earth asteroid that has a very slight possibility of someday hitting our planet.
By Andy Sullivan WASHINGTON (Reuters) - Hundreds of U.S. scientists have challenged a recent decision by an international astronomy group to strip Pluto of its planetary status with a petition rejecting its definition of what constitutes a planet.
By Alan Crosby PRAGUE (Reuters) - Pluto was stripped of its status as a planet on Thursday when astronomers from around the world redefined it as a "dwarf planet," leaving just eight major planets in the solar system.
The universe really is expanding - astronomers are proposing to rewrite the textbooks to say that our solar system has 12 planets rather than the nine memorized by generations of schoolchildren.
Astronomers led by an MIT professor have revised the scale used to assess the threat of asteroids and comets colliding with Earth to better communicate those risks with the public.
