Who is Watching Us: New Research About Exoplanets Emerges

alien planets

Ever wondered who is watching us from outer space? Well, you may think of tons of SF stories about different forms of life, and you might be just right. Recent research about exoplanets brings us quite insights.

A team of researchers wanted to find out how many exoplanets are getting a sneak peek at our marvelous planet. The result? Exactly 1,004 exoplanets.

These findings are similar to the Sun, with orbiting Earth-like planets, too, and other traits. So, if there’s anyone there, they can see us. 

Here is what you need to know.

“Somebody” is Watching Us

The team used data from NASA’s TESS (the Transiting Exoplanet Survey Satellite) and the Gaia star map and realized a series of measurements to find precisely how many exoplanets out there are watching us. 

Researchers explained that if the observers are really watching our planet, they would be able to spot any signs of a biosphere in our Pale Blue Dot atmosphere. But, they would also need to utilize similar techniques on Earth to record a distant object and detect how Earth passes in front of the Sun. Such a thing would bring them enough data to figure out our planet’s atmosphere and other features. 

Of the incredible amount of 1,004 stars captured as potentially habitable areas, 508 provide their surrounding planets at least a 10-hour observation window of our world with each orbit. 

However, most of them, 77 %, are defined as M-type or red dwarf stars, one of the coolest and smallest stars. Physicist Joshua Pepper from Lehigh University said:

“But all of the thousand stars we identified in our paper in the solar neighborhood could see our Earth transit the Sun, calling their attention.”

For now, the team believes their findings could be utilized for the quest for extraterrestrial life in the future. There are, of course, many things to figure out.
