Webb Telescope Captures New Details of Phantom Galaxy

The phantom galaxy is a “favorite target of astronomers studying the origin and structure of galactic spirals”, NASA and ESA said.

The James Webb Space Telescope has revealed dazzling new details of a previously known slice of the cosmos 32 million light-years away, in a new image released by NASA and the European Space Agency (ESA).

The telescope’s infrared technology, launched in December 2021, has allowed an even clearer view of the so-called ghost galaxy than astronomers have ever seen before.

“Webb’s sharp vision revealed delicate filaments of gas and dust within the grandiose spiraling arms that curl outward from the center of this image,” NASA and ESA said Monday.

“A lack of gas in the nuclear region also provides a clear view of the nuclear star cluster at the center of the galaxy,” the agencies said in a statement.

The swirling celestial shape, officially called M74, is located in the constellation Pisces 32 million light-years from Earth.

The Webb image shows the galaxy’s bright white, red, pink and light blue dust and star appendages swirling around a bright blue center, all against the dark background of deep space.

M74 was previously imaged by the Hubble Telescope, which captured the galaxy’s spiraling blue and pink arms, but instead showed its center glowing like a soft yellow.

The phantom galaxy is a “favorite target of astronomers studying the origin and structure of galactic spirals”, NASA and ESA said. The photo taken by Webb will help them “learn more about the early phases of star formation in the local universe” and record more information about 19 star-forming galaxies near our own Milky Way.

Astronomers will also use the image to “identify star forming regions in the galaxiesaccurately measure the masses and ages of star clusters and better understand the nature of the tiny dust grains drifting in interstellar space“, reads the press release.

Webb’s new images have thrilled the space community as the telescope orbits the Sun at a distance of one million miles (1.6 million kilometers) from Earth, in a region of space called the Second Point. of Lagrange.

The telescope, which has a primary mirror over 21 feet (6.5 meters) wide, is a international cooperation between NASA, ESA and the Canadian Space Agency. It should work for about 20 years.
