The European Planck Space Observatory revealed the universe is older than thought: 13.82 billion years old. See the role of the Cosmic Microwave Background here.

Astronomers have developed a way to detect the ultraviolet background of the universe, which could help explain why there are so few small galaxies in the cosmos.

Campus News Universe’s ultraviolet background provides clues about missing galaxies A new technique to detect the cosmic ultraviolet background radiation may show why there are so few small galaxies.

Soon, the universe became transparent to light. Yet the radiation of the universe's formation remained. Even as the universe expanded and evolved, that early radiation remained in the background.

Astronomers are trying to learn more about our universe's background hum, which could unlock new information about our universe.
