How the Moon Got Its Name

Almost every planet in our solar system and their respective orbiting moons have names taken directly from Greek and Roman mythology.

Why Orion's launch is the best news for humanity in a long time

I have always been sad that I never got to see the beginning of humanity's ultimate journey—and even sadder to realize that in 1972 we abandoned a path that could have possibly gotten us to other planets by now. On December 5, 2014, we opened the gate to that path again. We should rejoice—we are going back to the… » 12/05/14 8:57am 12/05/14 8:57am

All the planets in the Solar System fit between the Earth and the Moon

I never thought of this, but you can fit all the planets in the Solar System back to back into the distance from the Earth to the Moon—about 238,900 miles (384,400 kilometers)—with room to spare: 4,990 miles (8,030 kilometers.) Seeing it visualized really give you a good idea of how much empty space is out there. » 10/23/14 10:42pm 10/23/14 10:42pm

When Apollo astronauts landed on the moon, they left flags and footprints, yes, but also dozens of scientific instruments. Among them was a network of seismometers originally meant to study moonquakes. Forty years later, data from these seismometers are still helping physicists understand how to detect elusive… » 9/30/14 5:25pm 9/30/14 5:25pm

This perfectly timed picture is not of a solar eclipse

I know this picture looks like the Moon is passing perfectly between the Earth and the Sun. And I know it seems like the people in the picture are trying to look at the eclipse.
