NASA's new SPHEREx telescope is mapping the entire sky in infrared, helping scientists study the origins of stars, planets, and life—and the data is shared publicly. Researchers also propose a new type of glowing object called a "dark dwarf," powered by dark matter, which could offer clues about what dark matter is. Meanwhile, a giant object named 3I/ATLAS, recently spotted speeding through our solar system, is confirmed to be interstellar and may reveal how planets form in other star systems.
