It turns out that our moon can take a few hits. Scientists have found that the moon's crust is as fractured as it possibly could be after the beating it took 4 billion years ago.

There may be a new model for studying and cataloguing the universe. Scientists have created "Celeste," a new statistical analysis model that's designed to enhance sky surveys.
Astronomers have officially spotted some of the earliest galaxies in the universe.
This image may look like something Van Gogh painted, but that's far from the truth. Taken by ESA's Planck satellite, this picture actually shows two Magellanic Clouds, among the nearest companions of our Milky Way galaxy.
The moon isn't the only thing that can eclipse the sun. In this case, the International Space Station (ISS) had its turn. NASA has released a new composite image that shows the ISS passing in front of our nearest star.
