Moon

Scientists have known about ice in the dark, deep craters at the moon's poles, some of the coldest known places in the universe, but voyaging into one just wouldn't be likely.

The Moon Has More Water and Ice Hidden All Over Its Surface Than Originally Predicted

Scientists discovered that water is stored in tiny patches all across the moon's surface, not just in the deep, freezing craters of its south pole

Halloween features a full moon every 19 years, and it's always a blue moon.

The projected path for 2020 SO, a space object that astronomers predict will become Earth's mini-moon in October, possibly staying until May 2021. The blue object in the center of the circle is Earth.

Earth May Soon Get Another Mini-Moon, but It's Probably Just a Piece of Space Trash

It could be an asteroid—or, as one astronomer suggests, it could be a rocket booster from the 1960s

On Earth, most people are familiar with ultraviolet radiation’s harmful effects on our skin, but in space, astronauts are also subjected to galactic cosmic rays, accelerated solar particles, neutrons and gamma rays.

Here, scientists at the Goddard Geophysical and Astronomical Observatory use the visible, green wavelength of light to shoot lasers at the Lunar Reconnaissance Orbiter. The laser facility at the Université Côte d’Azur in Grasse, France, developed a new technique that uses infrared light, which is invisible to the human eye, to beam laser light to the Moon.

Scientists Shot Lasers at a Lunar Orbiter for a Decade. Then, One Bounced Back
