An astronomer has created a very beautiful image using data from the James Webb Nasa space telescope. This is a ‘Purple Galaxy’ image known as Messier 74 (M74). This galaxy is located 32 million light years from Earth in Pisces constellation. This is known as a phantom galaxy.
How ghost galaxy images are processed
Gabriel Brammer, a professor at the Cosmic Dawn Center at the Niels Bohr Institute, University of Copenhagen, made color images from the data processed available for free on the Barbara A. Mikulski portal for the Space (MAST) telescope portal. Data has been collected by the Ibbb (Miri) medium infrared instrument.
Brammer arranged views of three of the nine filters in the instrument.
Brammer translates each infrared wavelength to red, green, and blue, and then combines it to produce one picture.
The Phantom Galaxy looks like “Whirelpool of Purple which radiates counterclockwise from the Galactic Center”, an article published by Inverse.
The beautiful Spiral Galaxy M74 is the universe of the island around 100 billion stars. It has two prominent spiral arms.
Dr. Janice Lee, head of scientist in Gemini Observatory, said on Twitter that “we drink from Firehose”.
According to the article, Lee and colleagues of researchers collected blocks of the Phantom galaxy building as part of ‘Physics in high angle resolution in the nearest galaxy survey (Phang), which focused on spiral galaxies. This is because the amount of spiral galaxy information that contains the formation of “extraordinary” stars.
Nasa said in a statement that JWST touched so many different phases of the star’s life cycle, all in “extraordinary resolution”.
Allison Kirkpatrick, a supermasi -black hole expert and space dust, posted two galaxy images on Twitter. One of them was imaged by Spitzer Space Telescope and the others were captured by JWST.
What is shown by purple?
In another tweet, Brammer writes that the purple cast is actually “real” in the sense that the emissions of “inter -star cigarette smoke”, which is a polarisomatic hydrocarbon, makes the filter used for blue and red channels brighter relative to green.
According to an article published by New Scientist, Citra NGC 628 compared to Doctor Who Vortex. This is a fiction time vortex described in the Doctor WHO series which is famous as a dimensional field that is functionally forming a way between different time and spaces that allow doctors in the show to travel between them.
Michael Merrifield, a researcher at the University of Nottingham, England, said the typical purple appearance of Brammer images was due to the unique chemical composition of NGC 628 dust clouds, which consisted of polyclic aromatic hydrocarbons, according to the article.
Merrifield added that data can reveal how dust is made and distributed in galaxies.
Another picture of the ghost galaxy
Astronomers have long admired M74 as a perfect example of the Grand Design Spiral Galaxy.
JWST has brought the middle region of the M74 into a sharp focus on another picture. According to NASA, the color combination of the image data set comes from two webb instruments, close infrared cameras (NIRCAM) and Miri. The instrument operates each at the near and middle infrared wavelength. The picture shows a cooler star and a dusty structure in the Grand Design Spiral Galaxy.
