The fact that Mars' south pole holds many underground lakes suggests that they might be the last remnants of the planet's ancient oceans.

Briny Underground Lakes May Be All That Remain of Martian Ocean

New data confirm the 2018 discovery of a lake under Mars' south pole and point to three smaller water features around it

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.
