During its recent mini-moon stint, scientists studied the 2024 PT5 from Earth. Based on the cosmic object's composition and ...

They needed some space. New research suggests Pluto may have had a “kiss” with its largest moon billions of years ago in a ...

On Jan. 13, bright Mars will disappear behind the full moon for several hours. It's the only lunar occultation of Mars ...

Unlike Earth, where the Moon orbits the planet, Pluto and Charon orbit each other, forming a binary system that is more ...

The Wolf Moon, January's full moon, will reach peak illumination Monday. The previous full moon was December's Cold Moon.

Pluto and its largest moon Charon could have come together via a 10-hour “kiss-and-capture” encounter after a grazing ...

Charon is large in size relative to Pluto, and is locked in a tight orbit with the dwarf planet. A new simulation suggests how it ended up there.

Researchers at NASA’s Jet Propulsion Laboratory (JPL) have calculated a new system for measuring lunar time. While not needed ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

These changes in appearance are the phases of the moon. As the moon orbits Earth, it cycles through eight distinct phases. The four primary phases of the moon (new moon, first quarter, full moon ...

This "kiss and capture" mechanism offers a fresh perspective on planetary formation, particularly about Pluto and its largest ...

"The temperature just wildly swings from extremely hot to extremely cold," John Monnier, a professor of astronomy at the ...
