JWST Improves Its Detection Techniques, But Fails To Find Planets at Epsilon Eridani
Sometimes in science a negative result is just as important as a positive one. And sometimes data artifacts get the better of even the best space observatories. Both of those ideas seem to hold true for the James Webb Space Telescope’s recent observation of Epsilon Eridani, one of our nearest stars, and one that has decades worth of debate about whether there is a planet orbiting it or not. Unfortunately, while JWST’s NIRCam did find some interesting features, they were too close to a noise source in the telescope's instruments to be definitively labeled a “planet”. Their results were recently published on arXiv, and while it may sound disappointing, this type of work is exactly how science progresses.
