moon

The moon is a round, rocky body, but is it a planet? The answer, scientists say, is complicated.

A Japanese astronomer captured several impacts on the moon during the Geminid meteor shower.

Scientists have shown that a "remelting event" more than 4.3 billion years ago "reset" the internal clock of most lunar rocks, which has helped obscure the moon's true age.

The Cold Moon — the 12th and final full moon of 2024 — will rise on Sunday (Dec. 15). It will ascend higher into the night sky than any other full moon this year to sit alongside the planet Jupiter.

The answer depends on many factors, including the amount of fuel needed, the moon's orbit and the mission's objectives.

The Space Launch System blasts off from its Florida launchpad.

Using Einstein's theory of general relativity, physicists found that clocks on the moon would run 56 microseconds faster than clocks on Earth. That finding will help future lunar missions navigate.

Canada will soon roll a rover onto the moon, and you can help name the pioneering machine.
