This artist’s illustration portrays two galaxies that existed in the first billion years of the universe. The larger galaxy at left hosts a brilliant quasar at its center, whose glow is powered by hot matter surrounding a supermassive black hole. Scientists calculate that the resolution and infrared sensitivity of NASA’s […]

The Earth and Moon, shown here in a composite of two images from the Galileo mission of the 1990s, have a long shared history. Billions of years ago, they had connected magnetic fields.
