Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's responsible for the orbits of the planets and their satellites, but there ...

The number of planets that orbit the sun depends on what you mean by “planet,” and that’s not so easy to define ...

In classical (or "Newtonian") mechanics, which describes the motion of macroscopic objects (i.e., things larger than an atom, ...

Astronomers may have found a star racing through our galaxy at an incredible speed—dragging a planet along with it! If ...

When you was at the top and at the lightest, it's like being on a planet with less gravity, like Mercury. But when you was at the bottom on that bouncy part where you felt a bit heavier ...

Canadian astronomers have taken an extraordinary step in understanding how planets are born, using the James Webb Space ...

We commonly experience gravity by being pulled downwards by the Earth. Gravity keeps all of the planets (including Earth) in orbit around the Sun. It also keeps the Moon in orbit around the Earth.

Our research interests have been primarily in understanding the physical processes that control the evolution of terrestrial planets (Earth, Moon, Mars, ...). Modern space exploration has provided ...

Besides quantum theory, general relativity is one of two pillars of modern physics – our working theory of gravity and of the very large, of planets, galaxies and the universe as a whole.

Blue Origin's New Shepard rocket and spacecraft completed its moon-gravity mission, but the capsule appeared to have a slight ...

These unexpected differences challenge current theories of disk evolution and planet formation ... which means gravity truncates the outer parts of the disk, but it is unlikely that the current ...
