![]() Cover the one you aren’t using if it is distracting. ![]() It will take time for your eyes to get used to the dark and seeing through the eyepiece of your telescope. Important: Looking through a telescope takes a little bit of skill and practice. Binoculars that are well suited for stargazing can also deliver satisfying results if you are on a budget. The red planet can be a very rewarding target to observe but it can also be very unpredictable: its own atmosphere has a huge influence on what details will be visible for you.Īmong all the scopes that I’ve used, I have to admit that the refractors are a delight for planetary observing and suit my style which is more often than not short sessions with a quick setup. Patience and experience are paramount for planets observation. Many planetary observers use 4″ refractors very effectively to observe minute planetary detail. However, it is important to not underestimate what a 4″ scope can do. It usually requires an instrument of at least 115 to 130 mm and a strong magnification (up to 150x) for the first surface details to be visible. The best planetary telescopes usually feature a good focal length, and a decent aperture size is always helpful. 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.A home telescope of 60 to 100 mm in diameter with high magnification makes it possible to visualise the planet’s shape, but not much more. 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. 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 kilometres (nearly 932,000 miles) from Earth, observes the universe with wavelengths of light longer than those of other space telescopes. The Cassini division is the largest of the gaps in Saturn's ring system. ![]() Saturn's moons Dione, Enceladus and Tethys dot the left side, while the Cassini division, Encke gap and rings A, B, C and F are shown on the right side. The rings, however, remain bright, creating the "unusual appearance" of the planet in this photo, according to NASA. In the image, Saturn itself appears extremely dark due to the near-total absorption of sunlight by methane gas. Astronomers have discovered surprising details about Saturn's atmosphere, using a new image captured by NASA's James Webb Space Telescope. ![]()
