By shining a laser into the upper atmosphere, observatories can measure atmospheric distortion in real time and sharpen images of distant stars and galaxies. The technique, used at major observatories worldwide, has drawn renewed attention as part of wider coverage of modern telescope technology.","why":"A BBC explainer on laser guide stars has drawn fresh public interest in how observatories overcome atmospheric distortion.","tone":"neutral","entities":["astronomers","laser guide stars","observatories","BBC"],"summarized_at":"2026-09-30T11:40:13.730389Z","meta":{"via":"scan","lang":"en","term":"science","source":"BBC","published":"Wed, 30 Sep 2026 09:01:21 GMT"},"nw":null,"promo":null,"kind":null,"importance":null,"hidden":false,"hide_reason":null,"judged_at":null,"title_en":"Why astronomers make fake stars with huge lasers","section_name":"Science","category_name":"Science","timeline":[{"captured_at":"2026-09-30T11:38:51.810884Z","rank":32,"volume":null}],"posts":[{"platform":"news","url":"https://news.google.com/rss/articles/CBMilwFBVV95cUxNbUd6Q1l2Y1M0WXNIMjRxeV9pWDZydlh5NnprVTQyOXFLRk5XVktRTGVKZHRaVXprbUp5ZUU2MDlrY2hjbjR2ZEtSS0hVU3BqdEhVeW1HaWZPZmRIcnBrRENpSndxU0tSUWVLMEcyUjFobGJlRTFRU2dXalJueXp0T3k1R0Q2djNYOHBiTzY1N25iNHk1M1FB?oc=5","author":"BBC","title":"Why astronomers make fake stars with huge lasers","snippet":null,"posted_at":"2026-09-30T09:01:21Z","likes":null}],"elsewhere":[],"window":"7d"}}
