Caesar Cipher Puzzle

The solution to this cryptogram reveals a fascinating astronomical fact: Venus is the hottest planet in our solar system. While Mercury is closer to the Sun, Venus's incredibly dense atmosphere, primarily composed of carbon dioxide, creates a runaway greenhouse effect, trapping heat and raising surface temperatures to over 460 degrees Celsius (860 degrees Fahrenheit). This extreme heat is hot enough to melt lead, making Venus a stark example of how atmospheric composition can dramatically influence a planet's climate.

The hidden message was obscured using a Caesar cipher, one of the earliest and simplest forms of encryption. Attributed to Julius Caesar, who used it for secret communications, this substitution cipher shifts each letter in the plaintext a certain number of places down or up the alphabet. For instance, if the shift is three, 'A' becomes 'D', 'B' becomes 'E', and so on. This method, while easily broken by modern cryptanalysis, was effective in its time and represents a foundational step in the long history of cryptography, the art and science of secure communication.
