A complex structure of escaping helium spanning more than half the orbit of the ultra-hot Jupiter WASP-121 b

JWST observations of the ultra hot Jupiter WASP 121 b reveal helium escaping for most of its orbit, forming two giant tails moving in opposite directions. The results show how stellar radiation modifies planetary atmospheres.

Diversity in the haziness and chemistry of temperate sub-Neptunes

The cool sub-Neptune LP 791-18 c, with an equilibrium temperature of 355 K, was found to host a hazy atmosphere, distinct from any other temperate sub-Neptune studied so far. The discovery demonstrates the intrinsic diversity of these worlds.

Continuous helium absorption from both the leading and trailing tails of WASP-107 b

JWST observed helium and water in the atmosphere of the giant planet WASP-107 b, revealing a vast outflow of gas and evidence for recent inward migration. The findings shed light on how giant planets lose mass and evolve over time.

Toxoplasma gondii infection and chronic IL-1 elevation drive hippocampal DNA double-strand break signaling, leading to cognitive deficits

Chronic brain infection and IL-1 exposure impair spatial memory by triggering DNA double-strand break signaling in hippocampal neurons. Blocking this pathway prevents memory deficits, suggesting new therapeutic prospects for various brain diseases.

Atomic iron and titanium in the atmosphere of the exoplanet KELT-9b

Cross-correlation analysis of high-resolution spectra obtained as the exoplanet KELT-9b transited its host star reveals neutral and singly ionized atomic iron and singly ionized atomic titanium in the exoplanet’s atmosphere.

Highly reflective white clouds on the western dayside of an exo-Neptune

A complete revolution of exo-Neptune LTT 9779 b was observed with the NIRISS/SOSS instrument onboard the JWST. The resulting full phase curve is indicative of an equatorial jet that transports heat from the dayside to the colder nightside, resulting in an asymmetric distribution of clouds on the planet.

Vertical structure of an exoplanet’s atmospheric jet stream

Ultra-hot Jupiters provide a unique window into atmospheric processes and this in-depth study enables integrated global snapshots of the atmosphere and more accurate identification of flow patterns, thus allowing for better comparison to models.

Nightside condensation of iron in an ultrahot giant exoplanet

Absorption lines of iron in the dayside atmosphere of an ultrahot giant exoplanet disappear after travelling across the nightside, showing that the iron has condensed during its travel.

Titanium oxide and chemical inhomogeneity in the atmosphere of the exoplanet WASP-189 b

The rich transmission spectrum of exoplanet WASP-189 b reveals its dynamical atmosphere with a three-dimensional thermochemical stratification, requiring the unification of dynamical, thermal and chemical models for its study.

Orbital misalignment of the Neptune-mass exoplanet GJ 436b with the spin of its cool star

Mapping the three-dimensional trajectory of a Neptune-mass exoplanet across the disk of its cool star reveals that its orbit is nearly perpendicular to the stellar equator, implying the existence of a yet-undetected outer companion planet.
