天空中是什么？在城市上空，在大多数云层之上，在遥远的地方，那是一颗彗星。图为4天前在巴西Brasília拍摄的彗星C/2024 G3 （ATLAS）令人印象深刻的尾巴。上周，这颗不断进化的彗星在水星轨道内绕太阳运行，由于距离太阳太近，早期有人担心它可能会解体——最近的证据表明，它确实解体了。在近日点附近，阿特拉斯彗星非常明亮，细心的观测者甚至在白天在太阳附近明亮的天空上看到了它。在过去的几天里，阿特拉斯彗星已经形成了一条长长的尾巴，在日落之后，用肉眼可以看到它的一部分，尤其是在地球的南半球。成长画廊：彗星ATLAS （G3）

What's that in the sky? Above the city, above most clouds, far in the distance: it's a comet. Pictured, the impressive tail of Comet C/2024 G3 (ATLAS) was imaged from Brasília, Brazil four days ago. Last week the evolving comet rounded the Sun well inside the orbit of planet Mercury, going so close there was early concern that it might break up -- and recent evidence that it really did. At one point near perihelion, Comet ATLAS was so bright that sightings were even reported during the day -- over the bright sky near the Sun -- by careful observers. Over the past few days, Comet ATLAS has developed a long tail that has been partly visible with unaided eyes after sunset, most notably in Earth's southern hemisphere.
