EARTH has loads of telescopes looking out into space for deadly asteroids but some may have found a way to sneak up on us.
Astronomers say the potentially hazardous rocky objects are hiding within the Sun's glare.
Most of our current tech is looking outward beyond the solar system, even the new James Webb telescope.
That's because it's just too bright to see anything, but it's created a bit of a blind spot.
