![]() "Thanksgiving in the United States is a historical commemoration but it has a spiritual dimension strongly associated with homecoming and giving praise for what has been bestowed upon us," Cristina De Rossi, an anthropologist at Barnet and Southgate College in London, told Live Science. Various cultures have celebrated bountiful harvests with annual festivals. Animals might prepare themselves for the upcoming cold weather, storing food or traveling to warmer regions. In the autumn, or fall, temperatures cool again. was 74.0 degrees Fahrenheit (23.3 degrees Celsius), 2.6 degrees above average, according to the National Oceanic and Atmospheric Administration (NOAA). ![]() Historically, the heatwave during the Dust Bowl Summer of 1936 was considered the hottest summer on record, but in 2021 the average summer temperature of the contiguous U.S. ![]() The above article has been published from a wire source with minimal modifications to the headline and text.In the Northern Hemisphere, summer starts on June 1 and runs to August 31 What is the hottest summer on record? This work on Saturn is just the first of a programme of observations of all four giant planets, and JWST is providing a capability beyond anything we've had in the past if we can get so many new findings from a single observation of a single world, imagine what discoveries await?" Fletcher said. "JWST can see in wavelengths of light that were inaccessible to any previous spacecraft, producing an exquisite dataset that whets the appetite for the years to come. These are warm vortices high in the stratosphere, heated by the sun's warmth during Saturn's long summer season.Īs the autumn equinox approaches in 2025, the north polar stratospheric vortex will begin cooling down and will disappear as the northern hemisphere recedes into the darkness of autumn. This is surrounded by a broader region of warm gases called the north-polar stratospheric vortex (NPSV), which formed in Saturnian spring and has persisted throughout its northern summer. The warm 1500-km wide north polar cyclone (NPC), which was first observed by the Cassini mission, can be seen at the north pole. In the image, created by combining just a few of the wavelengths observed by MIRI on JWST, the bright thermal emission from the north pole stands out in blue. "The quality of the new data from JWST is simply breath-taking we've been able to continue the legacy of the Cassini mission into a completely new Saturnian season, watching how the weather patterns and atmospheric circulation respond to the changing sunlight," said Professor Leigh Fletcher, from the varsity’s School of Physics and Astronomy. While Earth is heading for the northern autumn equinox in September, Saturn is heading for the northern autumn equinox in 2025, which means the north poles of both planets are heading for extended periods of polar winter. Northern hemisphere summer on both worlds is now coming to an end. However, Saturn takes 30 years to orbit the sun, so the seasons last for 7.5 Earth years. Like Earth, Saturn has an axial tilt and experiences seasons in the same way. The findings, published in the Journal of Geophysical Research: Planets by the University of Leicester researchers, provide new insights into the changing seasons on the massive outer planet, famous for its icy rings. The new observations, based on an analysis of new images taken by the powerful James Webb Space Telescope (JWST), also provided a last glimpse of Saturn's north pole, with its enormous warm vortex filled with hydrocarbon gases, before the pole begins to recede into the darkness of polar winter. ![]() A team of planetary scientists has found that Saturn's late northern summer is experiencing a cooling trend, as huge planetary-scale flows of air have reversed direction as autumn approaches.
