New simulations reveal that the climate, atmospheric chemistry and even global photosynthesis would be dramatically disrupted by an asteroid collision ...

YR4, which orbits the sun every four years and periodically crosses Earth's orbit. The nature of its orbit makes it a ...

Earlier this month, NASA revealed that samples collected from Bennu contain 14 of the 20 amino acids essential for life on Earth, as well as key organic compounds that play a role in forming DNA ...

In an update issued on February 7, NASA said the probability of 2024 YR4 hitting the Earth had gone from around 1.2 percent (one-in-83) to 2.3 percent (one-in-43).

A Bennu-type asteroid could lead to “severe environmental consequences,” researchers write, while acknowledging that a collision is not likely.

If Bennu did hit Earth, it would trigger an explosion equivalent to 1.4 billion tons of TNT. Not only could the 500-metre-wide rock threaten millions of lives, but a recent study predicted that ...
