Outer Space

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.

Scientists Tested Out the World’s Largest Digital Camera on a Piece of Broccoli

Soon, it’ll photograph the cosmos. But first, scientists used it to snap a highly-detailed picture of an ordinary vegetable

The blue areas in this composite image from the Moon Mineralogy Mapper (M3) aboard the Indian Space Research Organization's Chandrayaan-1 orbiter show water concentrated at the Moon's poles. Homing in on the spectra of rocks there, researchers found signs of hematite, a form of rust.
