NASA's Hubble Space Telescope reveals an ultraviolet view of Jupiter. NASA, ESA, and M. Wong ; Processing: Gladys Kober Check out this ultra-cool image of Jupiter taken by the Hubble Space Telescope. This is a color composite picture of Jupiter seen in ultraviolet, which reveals different features in Jupiter’s atmosphere.
One feature that stands out is Jupiter’s Great Red Spot — it is blue in this image! This giant storm looks unusually dark in ultraviolet because high-altitude hazes over the huge storm absorb UV photons before they are reflected back to Earth.the data used to create this ultraviolet image is part of a Hubble proposal that looked at Jupiter’s superstorm systems. The researchers plan to map deep water clouds using the Hubble data to define 3D cloud structures in Jupiter’s atmosphere. Ultraviolet light are short, high-energy wavelengths of light beyond what the human eye can see. Ultraviolet light reveals phenomena such as light from the hottest and youngest stars which are usually hidden in the dust of local galaxies; it can also reveal the composition, densities, and temperatures of the material between stars.A multiwavelength observation in ultraviolet/visible/near-infrared light of Jupiter obtained by the NASA/ESA Hubble Space Telescope on 25 August 2020 is giving researchers an entirely new view of the giant planet. Hubble’s near-infrared imaging, combined with ultraviolet views, provides a unique panchromatic look that offers insights into the altitude and distribution of the planet’s haze and particles. This complements Hubble’s visible-light pictures that show the ever-changing cloud patterns. Credit: NASA/ESA/STScI Since the human eye cannot detect ultraviolet light, colors in the visible light spectrum are assigned to the images, each taken with a different ultraviolet filter. This image was released in honor of Jupiter reaching both perigee and opposition. Perigee means when Jupiter reached its closest point to Earth this year, which occurred on November 1-2, 2023 The distance between the Earth and Jupiter at that time was 595 million km Opposition is when another object — Jupiter in this case – is opposite the Sun in our sky. That means Earth comes between the Sun and Jupiter. This happens on of November 2-3, 2023 at 5 UTC . An object’s opposition also usually means it’s a great time to observe it from Earth. If you look to the east in the evenings, you’ll see a very bright object – that’s Jupiter. A look even through a small telescope or binoculars will reveal the four largest moons of Jupiter. Three of those moons are bigger than Earth’s Moon, and one of them, named Ganymede, is the largest moon in the Solar System.
