A fictitious asteroid is headed our way, and a group of real experts is currently doing their best to deal with the grim situation. The week-long tabletop ...

Yang believes computer simulation models can generalize his results to all metal asteroid impacts and, in the process, answer several existing questions about asteroid interactions.

Some of the biggest brains in the international space community come together to defend Earth against a fictional catastrophic asteroid threat — with varied success.

NASA gathered about 100 experts to practice a hypothetical discovery of an asteroid with a 72% chance of impacting Earth. They had a politics problem.

NASA will run an asteroid impact simulation event over the course of the week as the space agency ups its game in the pursuit of keeping Earth safe from threatening space rocks.

In a recent NASA simulation, scientists had six months to stop a hypothetical asteroid from hitting Earth, and they failed. That wasn't enough time.

On Wednesday (Sept. 3), the asteroid 2025 QDB will come to within just over half the distance between Earth and the moon, and you can watch its progress live online.

Asteroid Launcher, a new web app that gives asteroid impact fanatics a shot at answering some of their questions on what an asteroid crash would be like.

It's like a preemptive strike, with less mess," the researcher said. Paek and his team developed a simulation to help determine the best type of defense based on an asteroid's various properties.

In a recent simulation, a fictitious asteroid was approaching Earth but experts couldn't stop it. NASA has led seven such simulations, and the participants only fully stopped the asteroid once. It ...

NASA reveals what is needed to destroy an approaching giant asteroid. Here are other details of its new simulation.

Asteroid experts have been simulating a large asteroid heading towards Earth. Friday is the conclusion to the realistic simulation and will reveal how well planetary defense efforts work in this ...
