Quakes look and feel different depending on the material their seismic waves pass through. This new video compares marsquakes to moonquakes and quakes here on Earth.

Asteroid 2006 QV89, a space rock that'll pass closest to Earth on September 9, will not strike Earth. Details here, including a recent, fortunate non-detection of the asteroid by ESA and ESO.

India's 2nd moon mission, Chandrayaan-2, successfully carried out its 3rd orbit-raising maneuver on Monday. It will soon enter trans-lunar orbit, with the goal of landing on the moon on September 7.

Astronomers didn't expect to see a thin disk around the supermassive black hole at the center of galaxy NGC 3147, some 130 million light-years away. They're using Einstein’s theories of relativity to understand the velocities involved, and the intensity of the black hole's pull.

For the last few decades, the search for extraterrestrial intelligence has focused on detecting radio signals. But a new collaboration between Breakthrough Listen and VERITAS will focus on looking for laser-like flashes of light.

NASA engineers are working on a new family of space robots that can roll, climb, and use artificial intelligence to navigate around obstacles in rough terrains on other worlds. Meet the family, here.

Exoplanet Gliese 3470 b fits nicely in size between our solar system's Earth and planet Neptune. Known as a "mini-Neptune," it likely has a rocky core beneath a deep, crushing, hydrogen-helium atmosphere. The analysis of its atmosphere is a first for one of these mid-sized worlds.

"We knew the Milky Way had a bar, like other barred spiral galaxies. But we only had indirect indications from the motions of stars and gas. This is the first time we see the galactic bar in 3D space, based on geometric measurements of stellar distances."

After many years of searching, astronomers have finally found what appears to be a circumplanetary disk - that is, a disk of gas and dust - surrounding a young exoplanet. Evidence suggests that moons may be forming there.

With virtually no atmosphere on the moon - and, therefore, no wind - flags that fly freely on Earth would hang like limp cloth in the lunar environment. So Apollo 11 engineers had to rethink flagpole design entirely.
