One is likely very dusty and the other very far away, but researchers need to obtain data known as spectra to determine which is which.Ĭlick here to find out more about the gravitational lensing effects that we see in this image. For example, two patchy spirals to the upper left of the elliptical galaxy have similar apparent sizes, but show up in very different colours. Although the two foreground galaxies are relatively close astronomically speaking, they are not actively interacting.ĭon’t overlook the background scenery! Like many Webb images, this image of VV 191 shows many galaxies that lie great distances away. Webb’s near-infrared data also show us the galaxy’s longer, extremely dusty spiral arms in far more detail, giving them an appearance of overlapping with the central bulge of the bright white elliptical galaxy on the left. This image of galaxy pair VV 191 includes near-infrared light from Webb, and ultraviolet and visible light from Hubble. These new observations from the Webb telescope “are just a hint at what this observatory will add to Saturn’s story in the coming years,” NASA says, “as the science team delves deep into the data to prepare peer-reviewed results.By combining data from the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, researchers were able to trace light that was emitted by the large white elliptical galaxy on the left through the spiral galaxy on the right and identify the effects of interstellar dust in the spiral galaxy. In the future, additional and deeper exposures from Webb will help astronomers examine fainter rings around Saturn, according to NASA. Over the years, Saturn’s atmosphere and rings have been observed by other missions such as NASA’s Pioneer 11, Voyagers 1 and 2, the Cassini spacecraft and the Hubble Space Telescope. This latest detailed image comes just weeks after the Webb telescope spotted a record-breaking water plume erupting from Saturn’s moon Enceladus, which feeds Saturn’s diffuse E ring, according to NASA. Time moved in slow motion during the early days of the universe Astronomers suspect that an intermediate-mass. The cluster is a dense collection of several-hundred-thousand stars. This affects the entire galaxy as the material snowplows into surrounding gas and dust. A Hubble Space Telescope image of the globular star cluster Messier 4. The "quasar winds" are propelling hundreds of solar masses of material each year. Using the unique capabilities of Hubble, astronomers have discovered that blistering radiation pressure from the vicinity of the black hole pushes material away from the galaxy's center at a fraction of the speed of light. A quasar emits exceptionally large amounts of energy generated by a supermassive black hole fueled by infalling matter. ![]() This illustration shows a distant galaxy with an active quasar at its center. Launched on Christmas Day in 2021, Webb can study the beginning of time more closely, hunt for unobserved formations among the first galaxies, and peer inside dust clouds where stars and planetary systems are currently forming. The brightening near the edge of Saturn’s disk might be due to high-altitude methane fluorescence (the process of emitting light after absorbing light) or emissions in the planet’s ionosphere or both. But the darker-than-usual appearance of the northern hemisphere could be from “an unknown seasonal process affecting polar aerosols in particular,” NASA says. Unexpectedly, “the large, diffuse structures in the northern hemisphere do not follow the planet’s lines of latitude, so this image is lacking the familiar striped appearance that is typically seen from Saturn’s deeper atmospheric layers,” according to NASA.ĭifferences in the looks of Saturn’s northern and southern poles are normal, according to NASA, as the northern region experiences summertime while the southern hemisphere is exiting winter darkness. These exposures test Webb’s ability to spot faint moons around the planet and its rings, since any newly discovered moons could help scientists better understand Saturn’s present and past systems. The image was taken with Webb’s Near-Infrared Camera, known as NIRCam, as part of a Webb program that involves several exceptionally deep exposures of Saturn, according to NASA. The near-infrared observations of the ringed planet are a first for the highly sensitive telescope, according to NASA - which, at 1.5 million kilometers (nearly 932,000 miles) from Earth, observes the universe with wavelengths of light longer than those of other space telescopes. ![]()
