NEW: Asteroid 2024 YR4 may threaten Earth. It won't be the last. But, there's good news: we're about to get two new anti-asteroid weapons.

That scientists can calculate the odds of a newly discovered space rock hitting us is, in fact, good news.

Astronomers will turn the James Webb Space Telescope towards asteroid 2024 YR4 next month. The most powerful telescope ever launched into space will provide a more accurate estimate of the size of the asteroid, which has a very small chance of impacting Earth in 2032.
