Different filters create different colors, with red jets visible when stars form and white dots representing young stars. A large arch is seen which is caused by a cavity created by a massive star that releases so much energy it heats all material around it and causes chemical reactions.

I Zwicky 18 is located roughly 59 million light-years from Earth and classified as a dwarf irregular galaxy.
The James Webb Space Telescope's observations suggest I Zw 18 has gone through several sudden bursts of star formation, creating two distinctly bright regions of white and blue stars at its core.
Wispy brown filaments surround the central starburst region in the new JWST photo. These filaments represent bubbles of gas that have been heated by stellar winds and intense ultraviolet radiation unleashed by hot, young stars.
The strongest starburst activity is now believed to have happened more recently in the northwest lobe as compared to the galaxy's southeast lobe based on relative populations of younger versus older stars found in each of the lobes.
Accuracy
The James Webb Space Telescope captured an image of the dwarf irregular galaxy I Zwicky 18. The bright region at the core appears as two distinct lobes, representing different periods of star formation.
Previous Hubble Space Telescope observations revealed fainter, older red stars within I Zw 18, suggesting its star formation started at least one billion years ago. While the JWST's observations previously capture dusty and evolved stars, the new image also shows signs of more recent star formation.
I Zwicky 18 has one of the lowest content of elements heavier than helium among all known galaxies in local universe. Such conditions are thought to be similar to those in some first star-forming galaxies at high redshift, so studying I Zw 18 should shed light on life cycle of stars and dust in early universe.
The James Webb Space Telescope is able to study the dwarf galaxy I Zwicky 18 in greater detail at infrared wavelengths. Building on observations taken by Hubble at optical wavelengths.
Deception
(30%)
The article is deceptive in several ways. Firstly, the author claims that I Zwicky 18 has gone through several sudden bursts of star formation and created two distinctly bright regions of white and blue stars at its core. However, this information contradicts previous Hubble Space Telescope observations which revealed fainter, older red stars within the galaxy suggesting its star formation started at least one billion years ago possibly as much as 10 billion years ago. Secondly, the author states that wispy brown filaments surround the central starburst region in the new JWST photo and these filaments represent bubbles of gas heated by stellar winds and intense ultraviolet radiation unleashed by hot young stars. However, this information is not supported by any scientific evidence or peer-reviewed studies which would link to facts without claiming them as such.

The article contains several examples of bias. The author uses language that dehumanizes the subject by referring to it as a 'dwarf irregular galaxy' which implies that it is inferior and less structured than our Milky Way galaxy. Additionally, the use of phrases such as 'sparkling stars' and 'new image from the James Webb Space Telescope' creates an emotional response in readers rather than providing factual information about the subject.

The article contains examples of religious bias and monetary bias. The author uses the phrase 'massive stars' to describe these objects in a way that implies they are important or valuable, which could be seen as an attempt to inflate their significance for financial gain.

This supernova happened about 350 years ago, so the material we are looking at has been stable for some time.
The James Webb Space Telescope (JWST) has captured a tightly bound pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. Look for them at the center of the red diffraction spikes, appearing as an orange-white splotch.
The JWST is an infrared telescope that looks at objects in wavelengths longer than those we can detect with our eyes.
JWST targets are viewed through several filters attached to the telescope, which capture slightly different images. Combining these images into a composite allows scientists to create full-color images.
Accuracy
The JWST targets appear red because they emit visual light that is longer wavelength than what we can detect with our eyes. The shorter wavelengths appear blue or purple.

The article is deceptive in that it implies the colors of objects captured by NASA's James Webb Space Telescope (JWST) are true to life. However, JWST captures images in near-infrared light which has a different spectrum than visible light and therefore appears differently to human eyes.
The article uses an image of Herbig-Haro 46/47 as an example of the colors captured by JWST. The image is orange-white, but if we could see it with our own eyes, it would appear in a different color due to the difference in wavelengths.

Bias
(85%)
The article contains a statement that the colors in JWST images are not real and they are chosen to enhance things to make it more scientifically digestible and engaging. This implies bias towards visual-light telescopes over infrared telescopes.
]JWST is an infrared telescope, meaning it "looks" at the universe in wavelengths of light that are longer than that of red light, which has the longest wavelength we can detect with our eyes.[]
Pagan and DePasquale also work with researchers to make sure the images are scientifically accurate.
The colors are added to the image later, as the data from the various filters are translated into the spectrum of visible light, Pagan explained.
