As Earthlings, most of us don’t spend a lot of extra time thinking about the gravity on our home planet. Instead, we go about our days only occasionally dropping things or tripping over furniture but ...

The movements of the planets in the Solar System are pretty difficult to get your head around, even before we get started on the dark matter which seems to keep galaxies together and rotating with ...

New research suggests that the planets in the Solar System may be acting as pacifiers for the Sun, subduing its activity. A ...

In our modern world, it is easy to assume that there is not much left to learn about science and our planet. However, this couldn't be further from the truth. In fact, scientists are still making ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets. A team of NASA ...

A new probe in development known as GIRO represents a low-cost step toward unlocking the secrets of the outer planets, all through the invisible pull of gravity. Engineers have designed a compact, ...

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it — very, very carefully. This is ...

The researchers estimate the newfound stars ignited just 2.7 million years ago and will eventually succumb to the black hole's gravity, merging into a single star within a million years. "This ...

The brightest planets in the night sky will shine as the 'planet parade' continues throughout February, plus be on the lookout for the Moon to join the line-up, and for Saturn to 'tag' Mercury in ...
