Para astronom mengaku menemukan tanda-tanda kehidupan setelah mengarahkan teleskop terbesar dunia ke bulan. Teknik ini akan membawa manusia bertemu alien. Tanda-tanda yang ditemukan di bulan ini dipantulkan dari Bumi dalam 'sinar Bumi' yang cahaya matahari dipantulkan dari Bumi ke bulan. Kini teleskop mulai bisa mencari 'jejak' nyata ini untuk memastikan keberadaan kehidupan di 'exoplanet' di bintang jauh.
Tanda-tanda kehidupan ini merupakan perpaduan oksigen, ozon, metana dan karbon dioksida yang mengkhianati keberadaan kehidupan organik. Para peneliti juga mempelopori metode super sensitif dalam mengidentifikasi tanda-tanda kehidupan ini.
"Cahaya dari planet jauh ini sangat sulit dianalisa. Namun cahaya yang dipantulkan planet terpolarisasi. Jadi teknik polarimetrik ini akan membantu mencari cahaya lemah exoplanet," kata Dr Stefano Bagnulo dari Armagh Observatory. Demikian seperti dikutip DM.
Kita tunggu saja kabar baik selanjutnya.
