It measures 130 to 300 feet across, a pebble compared to the asteroid that killed the dinosaurs, which is estimated to have been six to nine miles in length. On the other hand, on Feb. 15, 2013, an ...

Earth could face catastrophic consequences if hit by an asteroid similar to Bennu, according to new computer simulations.

Scientists recently completed computer simulations of what would happen to Earth if it were impacted by an asteroid with a ...

How would our planet physically react to a future asteroid strike? Researchers simulated an idealised collision scenario with a medium-sized asteroid using a state-of-the-art climate model.

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).

Is Earth really exceptional?  A new book seems to reaffirm that notion.  But given the right conditions, primitive life may be a mere byproduct of biophysics.
