Mars, the fourth planet from the Sun, is a subject of fascination for astronomers. Though significantly smaller than Earth, ...

Researchers for the Emirates Mars Mission now suggest that Deimos may have once been a part of the planet and was ejected from the planet and took up residence in orbit.

One summer night in 1877, American astronomer Asaph Hall was looking through his telescope in Washington, D.C. Mars was at its closest point to Earth in its orbit, and Hall had one question on his ...

New high-resolution images of tiny Deimos taken by an Emirati orbiter suggest that it may not be the captured asteroid that scientists once said it was.

A satellite from the United Arab Emirates revealed that Mars' moon Deimos is made of the same material as the Red Planet itself, hinting at an ancient collision.

Deimos, the smaller of Mars’s two moons, may be more like its planet than we realize. New, high-resolution views of the tiny moon were recently captured by a United Arab Emirates spacecraft n… ...

Some of the closest photos of Deimos in nearly 50 years suggest it's not a captured asteroid from space but may once have been a part of Mars.

European spacecraft Hera whizzed past Mars on Wednesday, and snapped an unprecedented view of Deimos, its lesser-known of two moons.

Hope has so far made a number of close flybys of Deimos while continuing to create planet-wide observations of Mars’ atmosphere.

What is their origin? Are they captured asteroids or were they once part of the Red Planet, like the Moon was part of ours? Now, the closest images ever taken of Deimos appear to indicate the latter.
