重力波背景終於被發現了？！🌌 (Was the Gravitational Wave Background Finally Discovered?!?)
- Pulsars are rapidly rotating and processing neutron stars whose jets sweep past the Earth, resulting in blips of electromagnetic radiation that repeat with extreme regularity, sometimes several hundred times per second.
脈衝星是一種快速旋轉和處理的中子星，其噴流掠過地球時會產生電磁輻射，這種輻射極為規律，有時每秒重複幾百次。
- Pulsars are rapidly rotating and processing neutron stars whose jets sweep past the Earth, resulting in blips of electromagnetic radiation that repeat with extreme regularity, sometimes several hundred times per second.
