EARTH has plenty 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 dangerous rocky objects are hiding in the sun’s glare.
Most of our current technologies look beyond the solar system, even the new James Webb telescope.
That’s because it’s just too bright to see anything, but it created a small blind spot.
Recent research using twilight telescopes has looked at the problem to get an idea of what we might be missing.
Research reveals previously undiscovered near-Earth objects, including asteroids.
Although the chances of an asteroid hitting Earth are slim, it’s not impossible and leaving it undetected can be deadly.
“Asteroid surveys are generally conducted at night and mostly find objects outside of Earth orbit,” warned Professor Scott Shepard in the Science Diary.
“This creates a blind spot as many near-Earth Objects (NEOs) could be lurking in the sunlight inside Earth’s orbit.”
“Defying the sun’s glare, new telescopic surveys search for asteroids heading toward the sun at dusk.
“These investigations have found many previously undiscovered asteroids in the Earth’s interior.”
Among them is the first asteroid with an orbit inside Venus.
And there is another one with the shortest known orbital period around the sun.
These were both found in the last two years.
So we should expect to hear about many more asteroids coming our way in the future.
