Rolling Boulders on the Moon
The influence of gravity is not uniform on the moon, and this has some cool results such as these rolling boulders. Granted, it isn’t direct, but still. Gravity acts on the lunar surface over time, changing the landscape: elevation, slope, craters and peaks. Boulders on the moon are very sensitive to inertia, and thus it is very easy for them to just keep moving.

Massive X-Ray Burst From Black Hole
The Chandra X-Ray Space Observatory has picked up something quite extraordinary: from the center of the spiral galaxy, M83, a massive outburst of X-ray radiation has been detected.
It is thought that this is due to the increase in intake of matter from the black hole’s companion star which is theorised to be a red giant which is more than 50 million years old.
