Now, in an unprecedented study spanning two decades, researchers using NASA\u2019s <a href=\"https:\/\/science.nasa.gov\/mission\/hubble\/\" rel=\"noopener\">Hubble Space Telescope<\/a> have uncovered new insights into the planet\u2019s atmospheric composition and dynamics. This was possible only because of Hubble\u2019s sharp resolution, spectral capabilities, and longevity.\u00a0<\/p>\n<p>The team\u2019s results will help astronomers to better understand how the atmosphere of Uranus works and responds to changing sunlight. These long-term observations provide valuable data for understanding the atmospheric dynamics of this distant ice giant, which can serve as a proxy for studying exoplanets of similar size and composition.<\/p>\n<p>When\u00a0<a href=\"https:\/\/www.nasa.gov\/history\/35-years-ago-voyager-2-explores-uranus\/\" rel=\"noopener\">Voyager 2 flew past Uranus<\/a>\u00a0in 1986, it provided a close-up snapshot of the sideways planet. What it saw resembled a bland, blue-green billiard ball. By comparison, Hubble chronicled a 20-year story of seasonal changes from 2002 to 2022. Over that period, a team led by Erich Karkoschka of the University of Arizona, and Larry Sromovsky and Pat Fry from the University of Wisconsin used the same Hubble instrument, STIS (the <a href=\"https:\/\/science.nasa.gov\/mission\/hubble\/observatory\/design\/space-telescope-imaging-spectrograph\/\" rel=\"noopener\">Space Telescope Imaging Spectrograph<\/a>), to paint an accurate picture of the atmospheric structure of Uranus.\u00a0<\/p>\n<p>Uranus\u2019 atmosphere is mostly hydrogen and helium, with a small amount of methane and traces of water and ammonia. The methane gives Uranus its cyan color by absorbing the red wavelengths of sunlight.<\/p>\n<p>The Hubble team observed Uranus four times in the 20-year period: in 2002, 2012, 2015, and 2022. They found that, unlike conditions on the gas giants Saturn and Jupiter, methane is not uniformly distributed across Uranus. Instead, it is strongly depleted near the poles. This depletion remained relatively constant over the two decades. However, the aerosol and haze structure changed dramatically, brightening significantly in the northern polar region as the planet approaches its northern summer solstice in 2030.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-wide\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/hubble\/solar-system\/uranus\/Hubble_Uranus_Full_STScI-01JQ4XJZ0ZNFHYWFKPM6A6WJ42.jpg?w=1500&#038;h=1600&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img decoding=\"async\" width=\"1500\" height=\"1600\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/hubble\/solar-system\/uranus\/Hubble_Uranus_Full_STScI-01JQ4XJZ0ZNFHYWFKPM6A6WJ42.jpg?w=1500&#038;h=1600&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Graphic titled \u201cHubble Space Telescope \u2013 Observations of Uranus,\u201d with 16 images of Uranus, arranged in a 4 by 4 grid showing changes in appearance of Uranus as observed by Hubble between 2002 and 2022.

So, over two decades, the Hubble team has only seen mostly northern spring as the Sun moves from shining directly over Uranus\u2019 equator toward shining almost directly over its north pole in 2030. Hubble observations suggest complex atmospheric circulation patterns on Uranus during this period. The data that are most sensitive to the methane distribution indicate a downwelling in the polar regions and upwelling in other regions.\u00a0<\/p>\n<p>The team analyzed their results in several ways. The image columns show the change of Uranus for the four years that STIS observed Uranus across a 20-year period. Over that span of time, the researchers watched the seasons of Uranus as the south polar region (left) darkened going into winter shadow while the north polar region (right) brightened as it began to come into a more direct view as northern summer approaches.<\/p>\n<p>The top row, in visible light, shows how the color of Uranus appears to the human eye as seen through even an amateur telescope.\u00a0<\/p>\n<p>In the second row, the false-color image of the planet is assembled from visible and near-infrared light observations. The color and brightness correspond to the amounts of methane and aerosols. Both of these quantities could not be distinguished before Hubble\u2019s STIS was first aimed at Uranus in 2002. Generally, green areas indicate less methane than blue areas, and red areas show no methane. The red areas are at the limb, where the stratosphere of Uranus is almost completely devoid of methane.\u00a0<\/p>\n<p>The two bottom rows show the latitude structure of aerosols and methane inferred from 1,000 different wavelengths (colors) from visible to near infrared. In the third row, bright areas indicate cloudier conditions, while the dark areas represent clearer conditions. In the fourth row, bright areas indicate depleted methane, while dark areas show the full amount of methane.\u00a0<\/p>\n<p>At middle and low latitudes, aerosols and methane depletion have their own latitudinal structure that mostly did not change much over the two decades of observation. \u00a0However, in the polar regions, aerosols and methane depletion behave very differently.\u00a0<\/p>\n<p>In the third row, the aerosols near the north pole display a dramatic increase, showing up as very dark during early northern spring, turning very bright in recent years. Aerosols also seem to disappear at the left limb as the solar radiation disappeared. This is evidence that solar radiation changes the aerosol haze in the atmosphere of Uranus. On the other hand, methane depletion seems to stay quite high in both polar regions throughout the observing period.\u00a0<\/p>\n<p>Astronomers will continue to observe Uranus as the planet approaches northern summer.<\/p>\n<p><em>The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe.
