The comet C/2024 G3 (ATLAS) graces the skies with its delicate greenish coma and faint, wispy tail, composed of sublimating ices and dust swept back by solar radiation and winds. This icy traveler, hailing from the outer reaches of the Solar System, offers a fleeting glimpse of primordial material left over from the formation of planets.

Captured from the urban perimeter of Uberlândia, Brazil, during a break in torrential rain, this fortuitous observation demonstrates the unpredictability of celestial phenomena and the persistence of astrophotgraphers. The comet’s dynamic appearance, shaped by its interaction with the Sun, reminds us of the transient beauty of these cosmic visitors as they pass through our skies.

Thus, exists stars with peak emission in practically the entire visible spectrum: blue, white, yellow, orange, red ...
