NASA is diving into the unique properties of a metal alloy known as Alloy 30, which actually shrinks when heated. This intriguing characteristic could play a crucial role in the success of the upcoming Habitable Worlds Observatory (HBO). As scientists work to stabilize super-sensitive space telescopes, Alloy 30 might just be the key to ensuring they perform at their best in the harsh conditions of space. The potential applications of this alloy could revolutionize how we explore the universe.
