Two comets will be visible in the night skies this month
Briefly

The Oort Cloud is almost invisible and theoretical, yet it acts as a reservoir for billions of icy bodies, supporting the existence of comets.
Comet C/2023 A3 will be at its brightest after Oct. 12, while C/2024 S1 may reappear around Halloween, illuminating our sky with celestial phenomena.
The Oort Cloud may hold keys to understanding life's origins on Earth, as crashing ice bodies from space could have delivered essential ingredients for life.
Comets from the Oort Cloud serve as indicators of Earth's cosmic environment, and their unpredictable nature keeps astronomers vigilant in their studies.
