Venus and the Triply Ultraviolet Sun : This was a very unusual type of solar eclipse. Typically, it is the Earth's Moon that eclipses the Sun. In 2012, though, the planet Venus took a turn. Like a solar eclipse by the Moon, the phase of Venus became a continually thinner crescent as Venus became increasingly better aligned with the Sun. Eventually the alignment became perfect and the phase of Venus dropped to zero. The dark spot of Venus crossed our parent star. The situation could technically be labeled a Venusian annular eclipse with an extraordinarily large ring of fire. Pictured here during the occultation, the Sun was imaged in three colors of ultraviolet light by the Earth-orbiting Solar Dynamics Observatory, with the dark region toward the right corresponding to a coronal hole. Hours later, as Venus continued in its orbit, a slight crescent phase appeared again. The next Venusian transit across the Sun will occur in 2117. via NASA
Not every image coming from JWST is created by the expert engineers and artists that convert data into a real image, amateurs have been putting their hand to it too.
On Twitter, Judy Schmidt has put her own graphical skills to the test from data obtained by one of the many proposals put to the JWST team.
While this has drawn some heckles, in reality, all images from JWST are converted from IR datasets into visible representations, and it's not just JWST, all non-visual images and of course, many Hubble images which are compound images taken with overlays from other types of telescope, maybe highlighting X-Rays or UV.
The raw data is still there for anybody that wishes to investigate further, so I think it's perfectly fine for anybody to do the grunt work, as long as they say who they are and how they did it.
This image from Hubble is compounded with UV to bring out the pinkish star forming regions and nebula, along with the dark dust lanes, but you can see the central region doesn't show half as much detail as the new JWST data does.
Moon in Inverted Colors : Which moon is this? It's Earth's moon -- but in inverted colors. Here, the pixel values corresponding to light and dark areas have been translated in reverse, or inverted, producing a false-color representation reminiscent of a black and white photographic negative. However, this is an inverted color image -- where the muted colors of the moon are real but digitally exaggerated before inversion. Normally bright rays from the large crater Tycho dominate the southern (bottom) features as easily followed dark green lines emanating from the 85-kilometer diameter impact site. Normally dark lunar mare appear light and silvery. The image was acquired in Southend-on-Sea, England, UK. Historically, astronomical images recorded on photographic plates were directly examined on inverted-color negatives because it helped the eye pick out faint details. via NASA
