The James Webb Space Telescope (JWST) is now capturing sharper images, thanks to a groundbreaking software fix by two PhD students from Australia, Max Charles and Louis Desdoigts.
Since its launch in December 2021, the JWST has faced challenges with its Aperture Masking Interferometer (AMI). This feature, designed to capture ultra-high-resolution images of stars and other celestial objects, was not performing as expected. Minor electronic issues with the infrared detector were causing blurry images, particularly of faint targets.
In contrast to the Hubble Space Telescope, which needed astronauts to conduct costly repairs in space, the JWST is positioned too far from Earth for such missions. Instead, Charles and Desdoigts stepped in to find a solution from the ground.
Under the guidance of their tutor Peter Tuthill, who designed the AMI hardware, the students developed a software solution named AMIGO (Aperture Masking Interferometry Generative Observations). This tool uses advanced simulations and neural networks to model how the telescope operates in space. Their algorithms effectively “deblur” the images, restoring the telescope’s full potential.
“Instead of trying to fix hardware, we tackled the problem with code,” shared Tuthill. The impact of their work is significant, as AMIGO has enabled JWST to achieve its clearest detections yet, including capturing images of a dim exoplanet and a nearby brown dwarf.
The success of their algorithm is not just technical; it’s also personal. To celebrate their achievement, Charles and Desdoigts got matching tattoos of the telescope’s iconic hexagonal mirror.
The excitement surrounding their breakthrough has resonated beyond academic circles. On social media, many users expressed their admiration for the students’ success. Tweets showcasing their tattoos went viral, highlighting the younger generation’s contributions to scientific advancements.
“Seeing a software solution expand the telescope’s scientific reach is incredibly rewarding,” Desdoigts noted. “And to know it was all done from the lab is just amazing.”
This achievement showcases the power of combining technology and creativity in science. With the JWST now capable of sharper images, it continues to enhance our understanding of the universe.
