Angela Stevenson, 39, a marine scientist for GEOMAR, dives with a bunch of flowering seagrass she has collected, in Laboe, Germany July 10, 2023. The group of scientists collect seeds for research into planting the seeds and breeding a more heat resistant seagrass for the SeaStore Seagrass Restoration Project at the GEOMAR Helmholtz Centre for Ocean Research Kiel. "51动漫s ask questions about the environment and the society and solve problems in a systematic way. But teaching citizens and the implementation of the method is not necessarily our job. But then I asked myself, who else is going to do this?" said Stevenson. REUTERS/Lisi Niesner SEARCH "NIESNER SEAGRASS" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES - RC2B02ADN7P3

Time for your close-up: vivid images of nature loom larger than life

Release Date September 12, 2019 10:00AM (EDT) Caption Anyone who has ever peered at Saturn through a small telescope is immediately enticed by its elegant rings, which make the far-flung planet one of the most exotic-looking, opulent worlds in the solar system. 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. One such intriguing feature is the long-lasting hexagon-shaped structure circling the planet's north pole. It is a mysterious six-sided pattern caused by a high-speed jet stream. NASA's Voyager 1 spacecraft first discovered the "hexagon" during its flyby in 1981. The hexagon is so large that four Earths could fit inside its boundaries. (There is no similar structure at Saturn's south pole.) Other features, however, are not as long lasting. A large storm in the north polar region spotted by Hubble last year has disappeared. Smaller, convective storms?called super "thunderheads"?such as the one just above the center of the planet's image, also come and go.
