A new mathematical study suggests that the abandoned Ascent Stage of the Apollo 11 mission's Eagle Lunar Module, long believed to have crashed on the Moon in 1969, may be circling our largest natural satellite in a stable orbit.

In 2018 astronomers announced the discovery of lakes of liquid water on Mars at the south pole. Sadly, a trio of new papers refutes the claim, with new experiments suggesting that the “water” signal was more likely produced by frozen clay instead.

Black holes are notoriously dark objects, but now astronomers have spotted strange light coming from behind one. The X-ray echoes seem to be the result of the intense gravity of the object warping space and bending the light back around into view.

Controversial physicist Avi Loeb is on the hunt for aliens again. His new Galileo Project aims to track unexplained oddities in the sky, study interstellar objects, and even examine the "possibility" of alien satellites watching us from orbit.

Fifty years ago this week, Apollo 15 lifted off on the first true lunar exploration mission. Using an improved Lunar Module, the ninth crewed Apollo mission featured the first vehicle to drive on the Moon, allowing astronauts to roam farther than ever before.

Are Sir Richard Branson and Jeff Bezos astronauts? Though both billionaires flew to at least the edge of space, they may not qualify for official astronaut wings according to recently revised FAA rules.

NASA's InSight has provided … well, insight, into the inner workings of the Red Planet. By monitoring marsquakes over the past two years, the instrument measured the thickness and composition of Mars’ crust, mantle and core, revealing some surprises.

The ISS is about to receive its third robotic arm, which will be capable of "walking" around the Russian segment of the orbital outpost all by itself. It will do so hand-over-hand thanks to the flexibility afforded by its seven motorized joints.

While the Hubble Space Telescope has provided us with a wealth of data, getting it into orbit was quite expensive. The SuperBIT telescope is an intriguing alternative, as it hangs beneath a balloon instead of being launched by a rocket.

Astronomers have captured the first clear images of a colossal moon-forming debris disk orbiting a distant alien planet. According to the authors of the new study, the disk has enough material to create three satellites the size of Earth’s Moon.

Space is an exceptionally strange place, full of signals and observations that defy our understanding of the universe. In trying to explain these mysteries, sometimes astronomers hypothesize extremely exotic objects that we haven’t yet found.

With Virgin Galactic and Blue Origin having sent their first full passenger flights into space, the Federal Aviation Administration is demonstrating that it's taking space tourism seriously by opening a new center to monitor commercial space launches.
