Those aliens would be the natural choice for Earthlings to look for, say the scientists — because they could have already had a chance to spot us, and thus might be primed to receive communications from Earth.

This illustration provided by the American Museum of Natural History depicts the planet Earth, center, with the Sun in the background. The line of spots across the center of the image indicates star systems which can see Earth as it goes in front of our Sun.
Astronomers calculated that 1,715 stars in our galactic neighborhood — and hundreds of probable Earth-like planets circling those stars — have had an unobstructed view of Earth during human civilization, according to a study Wednesday in the journal Nature.

Possible wavelengths for a hot Dyson Sphere to be detected in different black hole mass. The purple, blue, green, orange, and red regions indicate X-ray(0.01 − 10 nm), UV(10 − 400 nm), optical(400 − 760 nm), NIR(760 nm − 5 ๐m), and MIR(5 − 40 ๐m) wavelength, respectively.
A Dyson Sphere, a spherical structure that surrounds a star and transports its radiative energy outward as an energy source for an advanced civilisation, is one of the main targets of SETI.
