彗星C/2024 G3 ATLAS戏剧性地出现在地球的天空中。这颗彗星来自遥远的奥尔特云，于1月13日到达近日点。1月19日，位于智利阿塔卡马沙漠的ESO帕拉纳天文台拍摄到了这颗明亮的彗星。这颗阿特拉斯彗星在南半球的暮色中落下，用肉眼可以清楚地看到它壮观的尘埃尾巴。前景是天文台著名的辅助望远镜之一的封闭外壳。这颗彗星明亮的彗发已经变得弥散，其冰冷的彗核在接近太阳后明显解体，这仍然令南半球的观测者惊叹不已。成长画廊：彗星ATLAS （G3）

Comet C/2024 G3 ATLAS has made a dramatic appearance in planet Earth's skies. A visitor from the distant Oort Cloud, the comet reached its perihelion on January 13. On January 19, the bright comet was captured here from ESO Paranal Observatory in the Atacama desert in Chile. Sporting spectacular sweeping dust tails, this comet ATLAS is setting in the southern hemisphere twilight and was clearly visible to the unaided eye. In the foreground is the closed shell of one of the observatory's famous auxiliary telescopes. Still wowing southern hemisphere observers, the comet's bright coma has become diffuse, its icy nucleus apparently disintegrating following its close approach to the Sun.
