The latest view of
Saturn from NASA's Hubble Space Telescope captures exquisite details of the
ring system — which looks like a phonograph record with grooves that represent
detailed structure within the rings — and atmospheric details that once could
only be captured by spacecraft visiting the distant world. Hubble's Wide Field
Camera 3 observed Saturn on June 20, 2019, as the planet made its closest
approach to Earth, at about 845 million miles away. This image is the second in
a yearly series of snapshots taken as part of the Outer Planets Atmospheres
Legacy (OPAL) project. OPAL is helping scientists understand the atmospheric
dynamics and evolution of our solar system's gas giant planets. In Saturn's
case, astronomers will be able to track shifting weather patterns and other
changes to identify trends. Credits:

TITUSVILLE, FL – The most beautiful planet in our solar system never fails to inspire. Saturn shines in a gorgeous new just released portrait taken by NASA’s Hubble Space Telescope.
And in the post Cassini era, Hubble will continue to provide the best views of splendid Saturn for years to come!
“Saturn is so beautiful that astronomers cannot resist using the Hubble Space Telescope to take yearly snapshots of the ringed world when it is at its closest distance to Earth, NASA said in a press release today, Sept. 12.
The new portrait of the Gas Giant – see lead image above - was snapped by Hubble's Wide Field Camera 3 instrument while observing Saturn on June 20, 2019, as the planet made its closest approach to Earth, at about 845 million miles away.
You can also easily get glorious glimpses of gorgeous Saturn in backyard telescopes with its rings wide open and the giant moon Titan orbiting nearby – as I did last night at the American Space Museum in Titusville, FL near NASA’s Kennedy Space Center.
"These images, however, are more than just beauty shots. They reveal a planet with a turbulent, dynamic atmosphere. This year's Hubble offering, for example, shows that a large storm visible in the 2018 Hubble image in the north polar region has vanished. Smaller storms pop into view like popcorn kernels popping in a microwave oven before disappearing just as quickly. Even the planet's banded structure reveals subtle changes in color,” said NASA researchers.
“But the latest image shows plenty that hasn't changed. The mysterious six-sided pattern, called the "hexagon," still exists on the north pole. Caused by a high-speed jet stream, the hexagon was first discovered in 1981 by NASA's Voyager 1 spacecraft.”

Video Caption: This new Hubble Space Telescope
view of Saturn, taken in late June of 2019, reveals the giant planet's iconic
rings. Saturn’s amber colors come from summer smog-like hazes, produced in
photochemical reactions driven by solar ultraviolet radiation. Below the haze
lie clouds of ammonia ice crystals, as well as deeper, unseen lower-level
clouds of ammonium hydrosulfide and water. The planet’s banded structure is
caused by winds and clouds at different altitudes. Hubble’s Wide Field Camera 3
observed Saturn on June 20, 2019, as the planet made its closest approach to
Earth, at about 845 million miles away.

Watch this new time lapse movie compilation of several of Saturn’s icy moons circling the gas giant:
Video Caption: This Hubble time-lapse movie shows the orbits of some of Saturn's icy moons as they circle the planet over an 18-hour period. The video is composed of 33 Hubble snapshots of the planet, taken June 19 to 20, 2019, by the Wide Field Camera 3. The closer the moon is to Saturn, the faster it orbits, according to the laws of gravity. Credits: NASA, ESA, A. Simon (Goddard Space Flight Center), M.H.
