'''Yerdan tashqari razvedka qidirish''' (odatda '''SETI''' deb qisqartiriladi) — Yerdan tashqaridagi aqlli hayot belgilarini yoki signallarini aniqlashga qaratilgan turli xil saʼy-harakatlar va ilmiy loyihalar majmuidir.

Tadqiqotchilar boshqa sayyoralardagi sivilizatsiyalardan uzatilayotgan signallar izlarini qidirishda elektromagnit nurlanishni kuzatish, optik signallarni qidirish va Yerdan tashqaridan kelishi mumkin boʻlgan artefaktlarni oʻrganish kabi usullardan foydalanadilar<ref name="Schenkel_2006">{{cite magazine |last=Schenkel |first=Peter |date=May–June 2006 |title=SETI Requires a Skeptical Reappraisal |url=http://www.csicop.org/si/show/seti_requires_a_skeptical_reappraisal/ |url-status=live |access-date=June 28, 2009 |magazine=Skeptical Inquirer |volume=30 |number=3 |archive-url=https://web.archive.org/web/20091105105946/http://www.csicop.org/si/show/seti_requires_a_skeptical_reappraisal/ |archive-date=2009-11-05}}</ref><ref>{{cite magazine |last=Moldwin |first=Mark |date=November 2004 |title=Why SETI is science and UFOlogy is not |url=https://cdn.centerforinquiry.org/wp-content/uploads/sites/29/2004/11/22164643/p40.pdf |url-status=live |archive-url=https://web.archive.org/web/20220621035247/https://cdn.centerforinquiry.org/wp-content/uploads/sites/29/2004/11/22164643/p40.pdf |archive-date=2022-06-21 |access-date=2022-06-11 |magazine=Skeptical Inquirer}}</ref><ref name="NYT-20170628">{{cite news |last=Johnson |first=Steven |date=28 June 2017 |title=Greetings, E.T.

Zamonaviy SETI tadqiqotlari 20-asr boshlarida radio ixtiro qilingandan keyin boshlangan. Keyinchalik Ozma loyihasi, Wow! signalini aniqlash va 2015-yilda [[Stephen Hawking]] va [[Yuriy Milner]] tomonidan eʼlon qilingan 100 million dollarlik 10 yillik dastur — Breakthrough Listen tashabbusi bilan yanada rivojlangan. 1980-yillardan buyon xalqaro miqyosdagi saʼy-harakatlar uzluksiz davom etmoqda: SETI@home va Project Argus kabi jamoat tomonidan boshqariladigan loyihalar maʼlumotlarni tahlil qilish bilan shugʻullanmoqda<ref name="AP-20150720">{{cite news |last=Katz |first=Gregory |date=July 20, 2015 |title=Searching for ET: Hawking to look for extraterrestrial intelligence |url=http://apnews.excite.com/article/20150720/eu--britain-extraterrestrials-e52c157915.html |url-status=live |archive-url=https://web.archive.org/web/20150722045619/http://apnews.excite.com/article/20150720/eu--britain-extraterrestrials-e52c157915.html |archive-date=July 22, 2015 |access-date=July 20, 2015 |work=[[AP News]]}}</ref>. SETI hurmatli ilmiy soha boʻlib qolsa-da, uni koʻpincha qatʼiy ilmiy metodlarga va tekshiriladigan maʼlumotlarga tayanishiga qaramay, jamiyat tomonidan asossiz shubha bilan munosabat bildiradigan fitnalar nazariyasi va [[NUJ]] tadqiqotlari bilan qiyoslashadi. Avi Lobning Galiley loyihasi kabi aniqlanmagan havoda kuzatilgan hodisalar (UAP) boʻyicha oʻxshash tadqiqotlar SETI izlanishlariga yanada koʻproq eʼtibor qaratdi.

Oʻnlab yillik qidiruvlarga qaramay, begona razvedkaning tasdiqlangan hech qanday dalili topilmadi. Bu SETI’ga „haddan tashqari umidvor“ degan tanqidlarni keltirdi. Tanqidchilar SETI taxminiy va inkor etib boʻlmaydigan deb hisoblasa, tarafdorlar uni [[Fermi paradoksi|Fermi paradoksini]] hal etish va Yerdan tashqaridagi texnik belgilarni tushunishning muhim bosqichi sifatida koʻrmoqda<ref name="SETI at 50">{{cite journal |title=SETI at 50 |doi=10.1038/461316a |pmid=19759575 |journal=Nature |date=2009 |volume=416|bibcode = 2009Natur.461..316.|issue=7262|page=316|quote=Indeed|doi-access=free}}</ref>.
