![RMS vs bin-size of the residuals from our TTV fits (see Section 4.1). The four panels show the 2x2 different reduction-likelihood pairings considered in this work. The two jitter treatments find binning behavior worse than that expected from pure Gaussian noise (dashed line), and instead have a slope of ∼ − 1/3, similar to other NIRSpec PRISM results (e.g. Kipping et al. 2025). The inclusion of a GP to absorb time-correlated noise greatly reduces the slopes, as again expected.-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/JWST-Excludes.png?resize=1200%2C720&ssl=1)
[astro-ph.EP] To date, even with JWST, it has not been possible to test for exomoons as small as the Moon. Only two reported searches for exomoons around bound planets have […]

Exoplanet LP 890-9c May Reveal Secrets About The Edge Of Habitability
How close can a rocky planet be to a star, and still sustain water and life? A recently discovered exoplanet may be key to solving that mystery.

Hot Earth Or Young Venus? A Nearby Transiting Rocky Planet Mystery
Venus and Earth provide an astonishingly different view of the evolution of a rocky planet, raising the question of why these two rocky worlds evolved so differently. The recently discovered […]
