    Image from 2022 using infrared imaging with the goal of spotting clouds on Titan. The white spot that looks like a bubble reflection on the upper right of the image (1 o’clock?) is a cloud.

    This is not true color, but colors assigned to different the wavelengths that we otherwise cannot see. Visible light would not have allowed imaging deep enough into the atmosphere to see clouds.

      Surely you mean “to see anything but clouds”, right?

        Nope! They got to see two cloud actually! A second set of images exists from Keck Observatory with the other cloud.

        The thick atmosphere isn’t cloudy, just dense with methane.

        I’m not 100%, but the clouds are exciting I think because they demonstrate seasonal changes.

    A clearer picture, for those interested:

    http://annesastronomynews.com/wp-content/uploads/2012/02/Titan.jpg

    Source

    From the source:

    Titan is the only object other than Earth where liquid hydrocarbon lakes and seas have actually been found (by Cassini) in its polar regions – in abundance in the north polar region and at least one of approximately 20,000 km2, called Ontario Lacus, on its south pole. Just recently, there have also been long-standing methane lakes, or puddles, in Titan’s “tropics” discovered.

          This makes me wonder what would happen if someone ignited large explosives by some of these hydrocarbon pools… since there’s plenty of water ice, there’s oxygen tied up to react with…

        Titan is small, and distant, when compared to the photo in the thread.

        The photo in this thread is by Cassini, which was at least a thousand of times closer. Titan is 1.2 million KM from Saturn, which Cassini was orbiting, while Earth, which JWST “orbits” is at least 1.2 billion KM from Saturn.

      With its liquids (both surface and subsurface) and robust nitrogen atmosphere, Titan’s methane cycle bears a striking similarity to Earth’s water cycle, albeit at the much lower temperature of about 94 K (−179 °C; −290 °F).

      That’s way too cold in my opinion!

      In infrared. Titan basically looks like a brownish grey blob to the naked eye due to its incredibly dense atmosphere.

        Knowing it’s just color shifted makes me wonder if that white band in the upper right that looks like a reflection off the atmosphere is actually a reflection off the atmosphere. And also what method of color shifting was used. Are the colors representative of anything or did they just pick what made for the best photo?

          They basically remap wavelengths, so yes, absolutely those would be representative of real features, either in the atmosphere or on the ground.

          That said, absolutely, sometimes there’s a bit of artistic license in how the wavelengths are mapped.

          Edit: the space.com article on the image describes some of the physical features depicted:

    Very blurry for a powerful telescope. Wonder if it’s because moon is moving fast relative to close telescope so the effective shutter speed needs to be relatively high?

      JWST primarily looks at very large objects that are far away. Titan (and really everything in the solar system) is relatively close to us, but are tiny in comparison to galaxies/nebulae, so their actual size as they appear in the sky is a lot smaller.

        Also of note, most objects in the outer solar system are very dim.

      I would assume it’s because the object is too close. Like trying to do macro photography without a macro lense.

    People saying this is blurry… have you considered: every other image is stitched, edited, overlaid and colorized, whereas this is a picture that’s actually quite close to that from the camera of JWST.

      JWST doesn’t see visible light, so it’s blurry and false color.

      But JWST also wasn’t designed to take pictures of moons in our solar system, it was designed to take picture of the cosmic background and find stars with planets around them.

      This is like trying to use a telescope to look at your globe across the living room, it’s going to be blurry because it wasn’t designed for that.
