- sorae – Latest images of Uranus observed with the James Webb Space Telescope released
This was introduced by sorae in an article on December 23, 2023.Uranus observed with the Webb Space Telescope“is. This image is a pseudo-color image created from data acquired on September 4, 2023 by the near-infrared camera on board the James Webb Space Telescope.
According to the Space Telescope Science Institute (STScI), which operates the Webb Space Telescope, Uranus’ axis of rotation is tilted at approximately 98 degrees with respect to its orbit, and its orbital period is approximately 84 years. and night last for 42 years each, and summer and winter in the northern and southern hemispheres each last for 21 years. The current season for Uranus in the northern hemisphere is summer, and the summer solstice is in 2028. On the other hand, in 1986, when the National Aeronautics and Space Administration (NASA)’s planetary probe Voyager 2 arrived, the southern hemisphere was experiencing summer, but today the southern hemisphere is experiencing a winter with long nights.
Uranus, which appears as a gentle blue sphere in visible light, takes on a more dynamic appearance when observed in infrared wavelengths. The white polar cap that covers the main body is seasonal, and you can see that the area near the north pole is a little brighter than the surrounding area. Several bright storms are visible near the boundaries of the polar caps and at lower latitudes, and the researchers say their number, frequency, and location may depend on a combination of seasonal and meteorological influences. .
