The world’s premier space observatory has spotted a mysterious and huge, free-floating planetary-mass object that’s “just 20 light-years from Earth,” NASA announced. Researchers recently used the James Webb Space Telescope to study the atmosphere of this “Super Jupiter,” dubbed SIMP 0136.

After Friday's spectacle, a "planet parade" of this size won't appear in the night sky for several years, experts say.

The view was acquired on Sept. 14, 2017 at 19:59 UTC (spacecraft event time). The view was taken in visible light using the Cassini spacecraft wide-angle camera at a distance of 394,000 miles (634,000 kilometers) from Saturn. Image scale is about 11 miles (17 kilometers).

Beginning around sunset, Saturn will be situated closest to the horizon, followed by Mercury, Venus, Jupiter and Mars higher in the sky. While Neptune and Uranus also are within Earth’s line of sight, they’ll require binoculars or a telescope and are extremely difficult to locate, astronomers say.
