![]() Wong (UC Berkeley) IMAGE PROCESSING: Alyssa Pagan (STScI) via Public Domain SCIENCE: NASA, ESA, Amy Simon (NASA-GSFC), Michael H. Uranus, an ice giant, is the seventh planet from the sun. It has the third largest diameter in the solar system. The hexagonal storm was first discovered in 1981 by the Voyager 2 spacecraft. In the recent photo, Saturn’s hexagonal storm on its north pole is visible. For example, the faint blue color in the planet’s southern hemisphere represents the remainder of winter. A change in season on Saturn is indicated by the color of its bands. Previous Hubble images of Saturn from 2018, 2019 and 2020 showed that the planet undergoes seasonal transitions like Earth does. ![]() Saturn, imaged on September 12, is approaching autumn in its northern hemisphere. SCIENCE: ESA, NASA, Amy Simon (NASA-GSFC), Michael H. It's atmopshere mostly consists of hydrogen and helium. Saturn is the second largest planet in the solar system and sports thousands of ringlets made of ice and rock. New images show that activity at its center is slowing down while its outer edges are speeding up, the New York Times reports. The planet’s Great Red Spot is home to storms that have raged on for 150 years at 400 miles per hour. This year, Jupiter and Saturn were captured in intense, crisp detail. Jupiter’s newest portrait taken on September 4, 2021, revealed that recent storms called barges formed above its equator, reports Jamie Carter for Forbes. SCIENCE: Amy Simon (NASA-GSFC), Michael H. Jupiter, the fifth planet from the sun, is the largest in the solar system. Orbiting 340 miles high above Earth, the Hubble telescope has been eyeing the outer planets since the 1990s, where it has seen Jupiter flush red with stormy weather, imaged seasonal weather on Saturn and Uranus, and observed a dark spot occasionally appear and disappear on Neptune. Weather patterns on these planets are vastly different and still not fully understood. However, unlike terrestrial planets like Earth and Mars, gas giants consist of freezing concoctions of hydrogen, helium, ammonia, methane, and deep water-all wrapped around a hot core, per a statement. ![]() Planetary scientists interested in understanding how often and when certain weather patterns occur compare past and present images to understand how the planets change over time, reports Georgina Torbet for Digital Trends. Like Earth, other planets orbiting the sun experience atmospheric shifts and seasonal variations. Part of its yearly grand tour of the outer solar system, NASA’s Hubble Space Telescope captured new technicolor images of the giant planets: Jupiter, Saturn, Uranus, and Neptune. The collection of Hubble images released this month by NASA are part of the Outer Planets Atmospheres Legacy program (OPAL), which creates yearly maps of each planet, a statement explains.īy studying these fresh cosmic yearbook photos, astronomers gain insight into each planet's unique weather patterns. Understanding these planets' ever-changing atmospheres could in turn help researchers learn more about how similar systems on our planet work, reports Dennis Overbye for the New York Times.
