Vessels are sitting offshore by Brazil's Rio Grande anchorage in the Southern Atlantic Ocean, either waiting for their turn in the busy Port of Rio Grande or for the right sailing conditions to come in. They are situated over a large sediment plume coming from the Lagoa dos Patos . The province of Rio Grande do Sul experienced severe flooding in late September and early October this year when this image was taken, which might have contributed to the sediment-rich waters we are seeing. Phytoplankton offshore can feed off the nutrients carried in these plumes.This scene was taken by the OLI-2 instrument aboard Landsat 9 on October 5, 2023.<!-- NICAID(15592825) -->

NASA Telescopes Discover Record-Breaking Black HoleThis image contains the most distant black hole ever detected in X-rays, a result that may explain how some of the first supermassive black holes in the universe formed. As we report in our press release, this discovery was made using X-rays from NASA’s Chandra X-ray Observatory (purple) and infrared data from NASA’s James Webb Space Telescope (red, green, blue). The extremely distant black hole is located in the galaxy UHZ1 in the direction of the galaxy cluster Abell 2744. The galaxy cluster is about 3.5 billion light-years from Earth. Webb data, however, reveal that UHZ1 is much farther away than Abell 2744. At some 13.2 billion light-years away, UHZ1 is seen when the universe was only 3% of its current age. By using over two weeks of observations from Chandra, researchers were able to detect X-ray emission from UHZ1 — a telltale signature of a growing supermassive black hole in the center of the galaxy. The X-ray signal is extremely faint and Chandra was only able to detect it — even with this long observation — because of the phenomenon known as gravitational lensing that enhanced the signal by a factor of four. The purple parts of the image show X-rays from large amounts of hot gas in Abell 2744. Indexador: Space Telescope Science InstitutFonte: STScI<!-- NICAID(15589386) -->

On Sept. 7, 2023, during its 54th close flyby of Jupiter, NASA’s Juno mission captured this view of an area in the giant planet’s far northern regions called Jet N7. The image shows turbulent clouds and storms along Jupiter’s terminator, the dividing line between the day and night sides of the planet. The low angle of sunlight highlights the complex topography of features in this region, which scientists have studied to better understand the processes playing out in Jupiter’s atmosphere.<!-- NICAID(15589180) -->
