Intriguing and inspiring perspectives of our home planet from spacecraft cameras looking back at Earth.

A signal from the 1st stars

It’s potentially one of the most exciting astronomical discoveries of the decade. Astronomers have detected a signal from the 1st stars to form in the universe.

This asteroid will pass closer than the moon on Friday

And you can watch the passage of near-Earth asteroid 2018 DV1, live, on March 2.

See Mars moon Phobos drift in front of Saturn

Expand to full size to see this video from ESA’s Mars Express spacecraft, which caught a close-up view of the little Mars moon Phobos, moving in front of distant Saturn.

Astronomers detect earliest hydrogen

They used a radio telescope to peer back to a time only 180 million years after Big Bang - when the 1st stars were turning on - to observe the earliest-yet signals of hydrogen gas.

Moon’s water might be widespread

A new study suggests that the moon’s water is widely distributed across its surface, though it’s not necessarily easily accessible.

Some black holes erase your past

You can't survive a passage into a black hole ... or can you? A UC Berkeley mathematician says you could enter certain types of black holes, but your past would be obliterated and you'd have an infinite number of possible futures.

Supermassive black hole and host galaxy not evolving together?

Astronomers assumed supermassive black holes and their host galaxies evolve together and affect each other. They call it "co-evolution." But it's not happening in the distant galaxy WISE1029.

This asteroid sweeps closer than our moon today

The average distance of the moon is 239,000 miles (385,000 km). Asteroid 2018 DU will sweep significantly closer than that on February 25, 2018.

Mars rover finds possible rock stripes

The long-lived Opportunity Mars rover keeps finding surprises, including these possible stone stripes. On Earth, similar features result from repeated freezing and thawing of wet soil.
