The moon did indeed coalesce out of tiny bits of pulverized planet blasted into space by a catastrophic collision 4.5 billion years ago, two new studies suggest.The new research potentially plugs ...

These days, our neighbor Mars has just two moons: Phobos and Deimos. But according to a study published Monday in the journal Nature Geoscience, these little satellites may actually be the planet ...

An artist’s conception shows the collision of Mars with another celestial object. The scenario could have given rise to a debris disk, and eventually to Mars’ two present-day moons.

The collision is comparable to the one that formed our moon – another phenomenon Dr Canup is investigating – which is thought to have been formed when a Mars-sized object crashed into Earth 4. ...

Additionally, Mars's relatively weak gravitational pull makes it difficult to explain how the planet could have captured two ...

New model suggests Martian moons formed after a catastrophic collision. Pictured, an illustration of Mars with its two moons, Phobos and Deimos. NASA/JPL-Caltech/Malin Space Science Systems/Texas ...

The moon did indeed coalesce out of tiny bits of pulverized planet blasted into space by a catastrophic collision 4.5 billion years ago, two new studies suggest.

The origins of Mars’s moons Phobos and Deimos have long been an enigma, but they may have been formed when a icy, comet-like object slammed into the Red Planet ...

Look up at the moon and you are looking at the aftermath of a collision between the Earth and a planet the size of Mars, scientists have confirmed. Since the 1970s, astronomers have suspected that ...

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 ...

Part of the reason our moon is so different is that it likely did not form in the same manner as most moons. Instead, our moon is the result of a wandering planet’s collision with a very ancient ...
