Subj. studied with the help of telescopes

Answer:

SETI

Hint:

This scientific effort searches for signals from intelligent life beyond Earth, often using radio telescopes to scan the cosmos. The acronym stands for its full name, which includes the word "extraterrestrial."

Explanation:

This clue plays on the idea of a subject (abbreviated as "Subj.") that involves telescopes, which might first make you think of astronomy. But the twist is that "SETI" (Search for Extraterrestrial Intelligence) is the actual field that relies on telescopes to scan for signals from alien civilizations. The abbreviation "Subj." hints at the answer being a shortened term, and the reference to telescopes points to its observational methods.
