2022 AP7 takes five years to circle the sun under its current orbit, which at its closest point to Earth remain several million kilometers away. The risk is therefore very small, butin case ofa collision, an asteroid of that size would have adevastatingimpact on life. The dustlaunchedinto ...
A test to protect Earth from asteroids unleashed a swarm of boulders—and a new study suggests that there may be some unintended consequences.
(Image credit: NASA) Stars like our sun form when a huge cloud of gas (mostly hydrogen and helium) grows so large that it collapses under its own weight. The pressure is so high in the center of that collapsing mass of gas that the heat reaches unimaginable levels, with temperatures so...
