When our planet Earth is viewed from space, we are nothing but a speck in the vastness of the universe filled with more massive celestial bodies. Because of how vulnerable we are out, the greatest threat to life on Earth may come from space.
The danger posed by asteroids traveling dangerously close to Earth is only one of several dangers that our planet and its technology are facing from space.
Now scientists have just revealed that something massive is heading towards our planet Earth.
How big is this object, and how soon are we expecting it? Are we about to witness another asteroid impact just like the one that wiped out dinosaurs some millions of years ago?
