Take it ETZ…
Astronomers have several methods to detect exoplanets orbiting distant stars.

And, the systems we could use to find transiting exoplanets will change (slowly) over time.
This is known as the Earth Transit Zone, or ETZ.
These worlds might typically spend 1,000 years within the ETZ before stellar motions moved worlds out of alignment.
The universe is dynamic.
Stars move, we move.
One big question to be answered by astronomers (possibly both kinds?)
is how to identify which far-flung planets are home to planets within this habitable zone.
In the search for life in the cosmos, transiting exoplanets are currently our best targets.
Doing so allows researchers to study the gases which surround the planet.
Such studies have the advantage of being able to detect life too primitive to build radio telescopes.
Some of the stars identified in the study are among the most-intriguing targets in the search for extraterrestrial life.
Orbiting this star are at least twoEarth-mass worlds.
In 29 years, any extraterrestrial astronomers on those worlds will see the Earth start to transit the Sun.
