![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)
[astro-ph.EP] Epsilon Eridani b, the nearest known Jupiter analog, has its orbit and mass constrained from radial velocity (RV) and absolute astrometry, and its atmosphere from JWST/NIRCam imaging upper limits […]

Using Radio Waves to Detect Exomoons
Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to […]
