#C2025R3 #PanSTARRS #Comet #Space

El cometa R3 PanSTARRS, que cruza a la derecha de la imagen, probablemente se originó en la Nube de Oort, lo que significa que es una antigua reliquia del Sistema Solar de hace miles de millones de años. Su brillante cola de iones extendida brilla en azul cuando el gas que escapa del núcleo del cometa es ionizado por la luz solar.
