The James Webb Space Telescope began science operations for the first time in July, and NASA released Webb’s first images to much applause. What followed was a couple of months of spectacular discoveries, including the detection of carbon dioxide on an exoplanet. Now, however, scientists at Harvard and MIT are warning that James Webb’s data could be lying to astronomers.
The researchers published a new study in Nature Astronomy. In it, they detail how astronomers’ current interpretation of the James Webb data could undermine their ability to tell whether a planet is habitable. They say the current model used to determine how photos pass through a material is not up to the quality of the data provided by James Webb.
The researchers outlined the problem in a university press release, saying the current model cannot differentiate between the percentages of compounds discovered. Because of these discrepancies, our translation model does not reach the same accuracy that James Webb is able to capture. This means that James Webb’s atmospheric readings and other data could be misinterpreted.

Considering how much effort is being made to find habitable exoplanets, not being able to accurately and effectively translate the data Webb presents is a big problem. But this also raises the question of how we update the current model and make it as accurate as James Webb. To do this, the researchers say, we need to determine how light and matter interact.
They say this would allow us to create more defined models that can accurately translate the James Webb data. And with that in mind, we could rest easy knowing that any information gleaned from observing distant exoplanets was more likely to be scientifically sound and unproblematic.
James Webb continues to baffle scientists with its data, and not having a correct model to build it all on is a real shame. Hopefully, we’ll see improvements in the future, especially if they’re needed as much as these researchers say they are.
