Rogue planets, like the one shown in this artist’s concept, drift through interstellar space alone and are thought to be prevalent throughout the Milky Way. Two upcoming space telescopes could help find many more of these faint objects. (Credit: NASA/JPL-Caltech)
Our Milky Way galaxy is home to billions of planets orbiting billions of stars in billions of planetary systems. But lurking in the spaces between, not bound to any star, are free-floating worlds. Astronomers refer to these as ...read more

NASA’s Hubble Space Telescope (HST) was launched into orbit on the space shuttle Discovery on April 24, 1990. Thanks to its perch above most of Earth’s turbulent atmosphere, the telescope’s relatively modest 2.4-meter mirror has given us an unprecedented window on the universe for nearly 30 years. But just how much longer will Hubble last?
