The European Space Agency says one of its research satellites that had run out of fuel caused no known damage after re-entering the Earth's atmosphere.
NASA technologists working to advance a pioneering technology that promises to detect tiny perturbations in the curvature of space-time now want to apply the same technique to map variations in Earth's gravity field.
(Phys.org) —The effects of gravity are relevant when building houses or flying airplanes, but biologists have generally accepted that the average cell is too small for gravity to play a role in how it is built or behaves. ...
A satellite monitoring Earth's gravity field since 2009 will run out of fuel "in the coming days" and eventually crash, with little risk to humans, the European Space Agency said Friday.
ESA astronaut Jean-François Clervoy and ESA astronaut instructor Hervé Stevenin slipped into the roles of Neil Armstrong and Buzz Aldrin last week for an underwater simulation of the historic mission to the Moon.
A joint Australian-German research team led by Curtin University's Dr Christian Hirt has created the highest-resolution maps of Earth's gravity field to date—showing gravitational variations up to 40 percent larger than ...
The current theory of star formation has a problem: it cannot make big stars.
