'We hope the knowledge that globular clusters can be observed at from such great distances with JWST will spur further science and searches for similar objects.' 'Since we could observe the sparkles across a range of wavelengths, we could model them and better understand their physical properties, like how old they are and how many stars they contain. Iyer, of the University of Toronto and co-lead author of the study, said: 'Looking at the first images from JWST and discovering old globular clusters around distant galaxies was an incredible moment, one that wasn't possible with previous Hubble Space Telescope imaging. 'Think of it as guessing a person's age based on their appearance - it's easy to tell the difference between a 5 and 10-year-old, but hard to tell the difference between a 50 and 55-year-old.' Until now, astronomers could not see the surrounding compact objects of the Sparkler galaxy with Hubble Globular clusters are ancient collections of stars from a galaxy's infancy and contain clues about its earliest phases of formation and growth.įrom their initial analysis of 12 of these compact objects, the experts established that five of them are not only globular clusters but among the oldest ones known. They assumed that the sparkles could either be young clusters of actively-forming stars - born three billion years after the Big Bang at the peak of star formation - or old globular clusters. These dense groups of millions of stars may be relics that contain the first and oldest stars in the universe.ĭubbed 'the Sparkler galaxy', it got its name thanks to the compact objects appearing as small yellow-red dots surrounding it, referred to by researchers as 'sparkles.' Now, early analysis has zeroed in on one of these galaxies nine billion light-years away from Earth, and revealed that it is sparkling with some of the oldest-known star clusters, dating back to shortly after the Big Bang. “We (amateurs) can do more good work than the best professionals could do 30 years ago.One of the first spectacular images taken by NASA's new multi-million pound James Webb Space Telescope captured the universe's earliest galaxies. “To see a setup and how it operates is fascinating,” he said. ![]() Still, his passion for astrophotography remains strong. “Or it might stay in the basement,” he said. He is thinking of giving a few to a startup business he advises. When it was over, he had to remove his photographs from the walls and take them home.Ĭoles is not sure what he will do with the prints. On Friday, Coles was allowed to have a private event for roughly two dozen friends and relatives. So for 2½ years, only Fermilab employees could view the exhibit. But Wilson Hall - which used to host public lectures, concerts, film screenings and more - has not.Ĭourtesy of Eric ColesWhen Roses Aren't Red - APOD Februusing a red palette by Eric Coles of Glen Ellyn. The grounds and the Lederman Science Center have since reopened to the public. ![]() The laboratory was closed the next day because of the pandemic. Work to install the exhibit happened on March 20, 2020. The images Coles selected range in size from 10 by 12 inches to 30 by 40 inches. “Imaging the Cosmos: Astro Photography and Landscapes” had 34 metal prints from Coles and about 10 from Martin Murphy. The red one, left, is using RGB palette the other uses the Hubble pallette. Susan Coles displayed two of the Elephant's Trunk side by side to show how using different palettes changes the look of the images. That inspired Coles to approach the director of visual arts at Fermilab and ask if he could put on a show. He saw an astrophotography display in the gallery on the second floor of Wilson Hall. NASA has chosen his work 12 times for its Astronomy Picture of the Day.Ĭoles was a frequent visitor to Fermilab, attending lectures and other events every three to four weeks. Coles posts his images to, where he has 1,944 followers.
