Astronomers have taken a step towards understanding how the Moon might have formed out of a giant collision between the early Earth and another massive object 4.5 billion years ago. Scientists led by ...

The irregular shapes and orbits of Mars’s two small moons, Phobos and Deimos, have long been a subject of scientific ...

The story of creation, whether of worlds or moons, has long fascinated humanity. For decades, most scientists agreed that the Moon was born from a violent collision between Earth and a Mars-sized body ...

The formation of the Moon billions of years ago is cloaked in mystery. Most astronomers believe the young Earth, still cooling off from its formation, was struck by a mars-sized body called Theia, ...

How did the moons of Mars, Phobos and Deimos, form and evolve orbiting the Red Planet? This is what a recent study published in Icarus hopes to address as a team of researchers investigated the ...

Two primary theories explain planetary moon formation: gravitational capture within a planet's Hill sphere radius and simultaneous formation with the solar system during its accretion disk phase. A ...

The giant-impact hypothesis is presented as the leading explanation for the Moon's formation. The Moon's lower iron content, relative to Earth, is cited as evidence supporting the giant-impact theory, ...

Learn more about the time when the moon didn’t exist, and then hours later suddenly did. Einstein once asked whether “the moon exists only when I look at it?". It was rhetorical objection to the idea ...
