Stunning James Webb Space Telescope Image Transforms a Distant Galaxy Into a Sparkling Christmas Ornament
The perfect galaxy photo
The James Webb Space Telescope simply gave a spiral galaxy 230 million light-years away a recent sparkling glamor shot excellent sufficient for the Christmas tree.
While the galaxy has the instead un-attractive name of NGC 7469, it has been an exciting topic to study.
The purpose of the research
JWST has looked into NGC 7469 as part of a survey to comprehend star formation, the advancement of supermassive black holes, and how galaxies gravitationally interact and also merge across the large gulfs of space and time.
NGC 7469 is also very special. It has elegant, gorgeous spiral arms that we can observe along their complete extent, thanks to a whim of orientation: The flat of the galactic plane is facing us almost straight, giving us a stunning sight of the galaxy’s structure.
The galaxy also has a highly bright center, especially regarding infrared radiation.
This is due to the supermassive black hole around which the whole galaxy orbits is active: It has surrounded by product that’s falling, or accreting, onto the black hole, a process that produces a great deal of light as gravity and also friction heat the product causing it to shine.
At a distance of regarding 1,500 light-years from NGC 7469’s galactic center is another brilliant ring featuring furious star formation activity, named as a starburst. Because we can observe the galaxy very clearly, researchers can examine it to better comprehend the link between a starburst ring and also an active galactic core.
Such as the galactic core, starburst rings glow brightly in infrared, and the wavelength variety in which JWST views the Universe in such fantastic detail. Its observations of galaxies such as NGC 7469 are expected to yield unprecedented understanding into these processes and how they are connected.
New discoveries
Researchers have already discovered recent clusters of star development and straight evidence that dust is being destroyed very near to the galactic core– revealing that the activity is affecting the galaxy around it.
They also discovered that highly ionized, diffuse atomic gas is blowing out from the galactic facility at around 6.4 million kilometres (4 million miles) a hour. Shocks from this wind, a new paper currently in preprint discovered, are not influencing the starburst ring.
Another galaxy is simply off to the bottom left corner of JWST’s photo. That’s IC 5283, and it is locked in a gravitational dance with NGC 7469. Collectively, the 2 galaxies are named as Arp 298. You can observe enhanced areas of brilliant red on the edge of NGC 7469 nearest to IC 5283; that is likely because the more enormous galaxy is slurping nourishing star-forming gas from its smaller companion.
The starburst and perhaps even the galactic nucleus activity in NGC 7469 are thought to be the outcome of the interaction between the two galaxies.
The huge six-pointed feature that dominates the p is JWST’s diffraction spikes, an artifact produced by the physical structure of the telescope. So it is not, in fact, real … but of course looks beautiful.
