It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. With a telescope of 8inch or more, you should comfortably see the great red spot and enjoy the different colours made out by the belts and zones that constitute the planet’s surface. a free open source planetarium for your computer. The Great Red Spot is often visible through a telescope, although its size and visibility vary. Even in small telescopes, let’s say 4-inch aperture, Jupiter will look majestic and you should even be able to make out some of the 4 Galileans moons. It appears as a large reddish oval-shaped area amidst the cloud bands. Dobsonian telescopes are known to be the best type of telescope for planetary observation because they have a very large aperture and a very long focal length, which is excellent for obtaining the necessary magnification without losing too much brightness and detail. One of the most iconic features of Jupiter is the aforementioned Great Red Spot, a giant storm that has been raging for centuries. Galileo di Vincenzo Bonaiuti de Galilei (15 February 1564 8 January 1642), commonly referred to as Galileo Galilei (/ æ l l e o æ l l e / GAL-il-AY-oh GAL-il-AY, US also / æ l l i o-/ GAL-il-EE-oh -, Italian: alilo alili) or simply Galileo, was an Italian astronomer, physicist and engineer, sometimes described as a polymath. ![]() In good seeing condition and after your eyes have adapted to see through the eyepiece, you might even make it a couple of Saturnian moons. ![]() This time you should be able to see the separation more clearly. Our readers frequently ask us if there is one optical instrument that is best suited for planetary observation. You will be able to see Saturn and its rings with a little more resolution. Jupiter, center, and its moon Europa, left, seen through the James Webb Space Telescope’s NIRCam instrument 2.12 micron filter. Even if you are located in a city with light pollution, you should be able to easily find them. They usually look a little bit different than stars and they do not twinkle as much. The slightest turbulence can blur the image and the finer details are no longer perceptible.Įven with the naked eye, it is possible to spot the planets in the night sky. The most important thing is to try to observe them without atmospheric turbulence because the planets usually require higher magnification. To increase the chance of a good observing session, I usually plan my planetary stargazing sessions in the evening. According to, Jupiter will be visible overnight from New York between 7:33 p.m. and even then it will usually look about half the size of Jupiter through a telescope.

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. It is definitely possible to observe the planets with your home telescope.
