Artifact InSPECtor: Refining Data From Space Telescopes
[NASA] How do scientists studying space with data from a telescope hundreds of thousands of miles away know that what they are seeing is real? A new NASA project, Artifact […]
![Post-processed NIRCam images for the two epochs, with 1- and 2-σ contours of the expected position, computed with the posteriors of the Octofitter results: in white without including the images in the fit, and in green including the images, but without making a connection between flux and atmospheric model. The postprocessing method is described in Sec. 2.3. When including the images, some walkers tend towards the feature whose location coincides with the expected position of planet b. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/An-Updated.png?resize=1200%2C719&ssl=1)
