Scientists believe that gravitational forces and other factors in space could affect the orbits of planets, which means there’s a chance that Mars could collide with Earth. If this happens, the ...

New research published today in Science Advances proposes an alternative delivery mechanism: a catastrophic collision between Earth and a Mars-sized object, sometimes referred to as Theia, some 4. ...

Around 4.6 billion years ago, a young, hot star was born. The Sun formed from a cloud of gas and dust, and over time planetary bodies, including Earth and Mars, came to be. It’s unlikely that ...

One summer night in 1877, American astronomer Asaph Hall was looking through his telescope in Washington, D.C. Mars was at ...

Now researchers have shown that a collision with a Mars-sized impactor could explain Earth’s chemical composition (Sci. Adv. 2019, DOI: 10.1126/sciadv.aau3669).

But a new study published in Science Advances suggests that the building blocks for life on Earth came from a galactic collision with another Mars-sized object more than 4 billion years ago ...

The researchers believe that these volatile elements were delivered when a Mars-size planet collided with Earth 4.4 billion years ago. This collision also created our moon.

However, Earth's density is higher than that of Mars – 5.514 g/cm 3 compared to 3.93 g/cm 3 (or 0.71 Earths) – which indicates that Mars' core region contains more lighter elements than Earth's.

Earth contains a heavy version of silicon that is absent from Mars. The finding, detailed in today's issue of the journal Nature , suggests Earth’s core formed under very different conditions ...

Huge chunks of an asteroid that NASA sent a spacecraft slamming into may one day collide with Mars, new research has found. U.S ... none of the 33,000 near-Earth asteroids being tracked by NASA ...

In addition to the probability of colliding with Earth, they also found only a 2.5 percent chance the Tesla will collide with Venus in the next one million years.
