During the awards ceremony for the Hyperloop Pod Competition, Elon Musk commented on the possibility of Hyperloop on Mars

A massive rogue planet has been discovered in the Beta Pictoris moving group.

The discovery of gravitational waves generated by the collision of two massive black holes could revolutionize our understanding of the universe.

On Feb. 6th a bus driver in India was reportedly struck and killed by a falling meteorite. Did this really happen? Almost certainly not. We look at the details.

In the third and final article in our gravitational wave guide, we explain what kinds of events can generate these powerful ripples in spacetime.

The discovery of hundreds of galaxies, hidden from view behind the Milky Way, help shed light on the nature of The Great Attractor.

Time to brush up on your gravitational wave basics, if you haven't done so! In Gravitational waves and how they distort space, I had a look at what gravitational waves do. Now, on to the next step: How can we measure what they do? How do gravitational wave detectors such as LIGO work?

Astrophysicists using the Kepler Spacecraft have discovered the largest rocky planet yet: BD+20594b is 16 times as massive as Earth.

Also known as NGC 7089, Messier 2 is a large globular star cluster located in the constellation Aquarius, 33,000 light years from Earth.
