There's been plenty of talk about crewed missions to Mars happening in the next few decades. So when exactly will humans set foot on Mars?

Located in the direction of Sagittarius, approximately 10,000 light years from Earth, is the beautiful Small Sagittarius Star Cloud (aka. Messier 24)

Developed near the turn of the century, CubeSat technology has made space exploration and orbital research a lot more accessible.

In about 4 billion years, the Milky Way and Andromeda galaxies will collide. Known as a galactic merger, this process is actually quite common in our Universe.

During the early Space Race, both the American and Soviet space programs conducted tests flights using animals. In the Soviet's case, this include the famous "space dogs".

NASA's newest planetary probe, the OSIRIS-REx asteroid sampling spacecraft, is merrily snapping its 'First-Light' images following the successful power up and health check of all of the probes science instruments, barely three weeks after a stunning sunset launch from the Florida Space Coast - as it is outbound to asteroid Bennu.

This year's Nobel Prize in physics is expected to be be conferred on the three scientists who invented the process that led to the discovery of gravitational waves, but not the scientist who made it possible.

When it comes to space helmets, there's one rule: you keep your helmet on. But there might be a couple of places in the Solar System where you can take your helmet off, just for a few moments, and not die instantly.

Radiocarbon dating (aka. carbon dating) measures the half-life of carbon-14, which occurs naturally in our atmosphere, to determine the age of organic matter.

Some of the questions Elon Musk fielded at his recent presentation were truly embarrassing. But he handled it well.

KENNEDY SPACE CENTER VISITOR COMPLEX, FL - Sending humans on a 'Journey to Mars' and developing strategies and hardware to accomplish the daunting task of getting 'Humans to Mars' is NASA's agency wide goal and the goal of many space enthusiasts - including Apollo 11 moonwalker Buzz Aldrin.

Elon Musk announced the new Interplanetary Transport Ship on Monday. That night, Scott Manley recreated the spacecraft and booster in Kerbal Space Program.
