Kalau tahu bumi dapat sinyal radio dari entah berantah, berulang kali dan periodik. Apa yang kamu pikirkan gengs? Langsung inget alien atau mikir yah, cuma sinyal gak jelas paling?
Akhir-akhir ini bumi dapat sinyal radio secara berkala gengs. Sinyal radio misterius yang berdetak terus-menerus. Dari tempat yang super jauh berjarak 500 juta tahun cahaya. Jauh banget lah pokoknya.

Sinyal radio dari luar angkasa (amazon.co.uk)
Canadian Hydrogen Intensity Mapping Expreiment (CHIME) FBRs menemukan kalau ada pola detak ledakan yang terjadi setiap 16 hari. Selama empat hari, sinyal bakal melepaskan satu atau dua detakan setiap jam. Terus kembali hening selama 12 hari.
Detak ledakan yang dikelompokkan menjadi periode empat hari ini diamati pakai teleskop radio CHIME di British Columbia. Selama September 2018 hingga 30 Oktober 2019.

Peristiwa ini adalah awal penemuan besar untuk mendeteksi periodisitas sinyal yang disebut ledakan radio cepat atau Fast Radio Burst (FRBs). FRBs itu detakan atau pancaran gelombang radio dalam hitungan milidetik di luar angkasa. Bisa sekali atau berkali-kali.
Terus apakah sinyal ini dari makhluk luar angkasa?
