James Webb telescope captures ghostly image of a celestial nautilus 32 million light-years from Earth

James Webb telescope captures ghostly image of a elysian nautilus 32 million light- times from Earth 

The James Webb Space Telescope( JWST) has snapped a dramatic new image of a helical world that looks like a elysian seashell drafted from blue and pink candyfloss fibers of gas. 

The world, called M74, resembles the seashell of a nautilus, whose helical confines are allowed to observe the Fibonacci sequence. Also known as the Phantom Galaxy, M74 is located about 32 million light- times from Earth in the constellation Pisces. M74 is known as a" grand design curl" because of its prominent and well- defined helical arms. It's also directly in Earth's line of sight, which makes the world a popular target for astronomers studying the origin and structure of galactic gyrations. 


" Webb's sharp vision has revealed delicate fibers of gas and dust in the grandiose helical arms which wind outwards from the center of this image," European Space Agency( ESA) representatives said in a statement( opens in new tab)." A lack of gas in the nuclear region also provides an unobscured view of the nuclear star cluster at the world's center." 

The image comes from JWST'sMid-Infrared Instrument, which is sensitive to light in themid-infrared region of the electromagnetic diapason. 

The new image is part of the drugs at High Angular resolution in near worlds( PHANGS) check, a long- running check of stars, star clusters and dust within 19 worlds. The pretensions of PHANGS are to find star- forming regions in those worlds, measure the millions and periods of star clusters, and learn further about the small grains of dust drifting in astral space. 


PHANGS has formerly imaged those 19 worlds using the Hubble Space Telescope's Advanced Camera for checks, which makes JWST's images M74 perfect for an early comparison( opens in new tab) between the two space telescopes. 

Hubble's view of M74 shows aged, redder stars toward the center, youngish and bluer stars in the world's helical arms, and stars forming in red bubbles. JWST's new sharp infrared compliances are dominated by gas and dust within the world's arms as well as the thick cluster of stars at its core. 


" This new image( of M74) has remarkable depth," ESA representatives said." The red colors mark dust threaded through the arms of the world, lighter oranges being areas of hotter dust." The youthful stars throughout the arms and the nuclear core are blue, while heavier, aged stars toward the world's center are shown in cyan and green. Star- forming regions are represented by pink bubbles." Such a variety of galactic features is rare to see in a single image, ” ESA representatives said. 

The two space lookouts' images were also intermingled to produce a unique new compound image of M74( opens in new tab) in both visible light( from Hubble) and infrared light( from JWST). This compound image" showcases the power of space lookouts working together in multiple wavelengths," according to ESA.
