Bright Northern Lights Fill the Sky Across the UK

Bright green and purple lights filled the night sky across the United Kingdom on Friday and Saturday. Many people went outside to watch the colourful display, known as the northern lights or aurora borealis. Usually, people only see these lights in the far north, near Scotland or the Arctic. This weekend, people saw them unusually far south in southern England.

known as= 被稱為（用於介紹事物的別名或正式名稱）

The northern lights happen because of the sun. The sun sends tiny charged particles into space. When these particles reach Earth, they hit gases in the air around the poles. This collision releases energy as light. Oxygen creates green light, while nitrogen makes blue and purple colours.

because of= 因為、由於（後接名詞，用來表示原因）while= 而、然而（用於對比兩種不同的事實）

Weather forecasters said people might still see the lights until Tuesday if the sky stays clear. Experts also said 2026 is a peak year for watching the lights because the sun is very active right now.

might still= 可能仍然會（表示未來仍有發生的可能性）

延伸學習

•「northern lights」與「aurora borealis」指的是同一種現象；日常英語中常使用前者，而較正式或科學的用語則是源自拉丁語與希臘語的後者（北極光）。
•「peak」常作為修飾名詞用，例如「peak year」（高峰年）或「peak hours」（尖峰時段），用來描述活動或數量達到最高點的時期。
