Surprisingly, Pluto is able to maintain a gravitational grasp on much of its atmosphere even as ions are being stripped away by the solar wind.
An orbital experiment is about to test to see if objects really fall at same speed in a gravitational field -- or wither some exotic physics may be detected.
It's 'Star Wars Day' (May the Fourth), and we're wondering whether the planets depicted in 'The Force Awakens' were actually that far from reality.
For a long time, scientists have operated on the idea that new planets form around young stars. But it turns out that dying stars may also be able to make baby planets.
As we say goodbye to February, let's take a look back at this month's profound discovery of gravitational waves.
Now the elusive ripples in spacetime have been found, scientists are planning for a rich future for using gravitational wave observatories to unmask the warped side of cosmos.
We now have the ability to listen in on the most violent events in our cosmos. Thank you Einstein!
The merging black holes generated a gravitational wave signal from 1.3 billion light-years away -- but which direction did they come from?
