A dog-like, bio-inspired robot called Spirit is still learning to walk, but could one day be deployed on the moon to explore steep, potentially hazardous areas with a team of robot companions.

As a revival of the lunar race inches closer, scientists have just begun working out a key question: What time is it on the Moon?

"As the world's oceans continue to warm, coral bleaching is becoming more frequent and severe."

"We want to make sure that for all the spacecraft we are likely to launch in the future, we will be taking action to make sure that we de-orbit and bring it to a safe location."

"We were surprised with seeing such a large number of candidate objects."

An incredibly brief, ultrabright explosion has led astronomers to a newfound magnetic star outside the Milky Way, which could be the first of many extragalactic magnetars, according to new research.

The nebula's shell is expanding at rates equivalent to traveling from Earth to the moon in just over seven minutes.

Satellites reveal denser green patches of vegetation where beavers were reintroduced.

"The better astronomical observations of the real thing can be, the more accurately we can reproduce what we see with our experiments on Earth."

"The key to protecting Earth from being hit by asteroids is knowing where all these are."
