The most otherworldly, mysterious forms of lightning on Earth

Our atmosphere is like one big electrical circuit: Thunderstorms are the batteries that charge it up, and lightning is the current flowing through it.

These fantastical terms refer to light displays called transient luminous events or TLEs that occur in Earth’s upper a

The Rust programming language is well known for its ownership-based type system, which offers strong guarantees like memory safety and data race freedom. However, Rust also provides unsafe escape hatches, for which safety is not guaranteed automatically and must instead be manually upheld by the programmer. This creates a tension.
