Overview of the James Webb Space Telescope Observatory [PDF]

, 2011
The James Webb Space Telescope (JWST) is a cryogenic, 6.5 meter diameter space telescope. JWST has a unique architecture, compared to previous space telescopes, that is driven by its science requirements, ia passively cooled cryogenic design, and the ...

Response of Tropical Climate and Extreme Precipitation to Ocean Temperature in Convection‐Permitting Aquaplanet Simulations

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract Tropical climate and weather systems are integral to the global hydrological cycle. Yet, their detected and projected trends are highly uncertain in part due to shortcomings of Earth system models. This study uses novel aquaplanet simulations with different sea‐surface temperature and with convection‐permitting resolution in the tropics to ...

Evidence for a Nonzero Eccentricity Superpuff Exoplanet WASP-107 b Using JWST Occultation Observation

The Astrophysical Journal Letters
WASP-107 b is an extremely low-density superpuff exoplanet whose inflated radius and evidence of strong internal heating make it a key target for understanding planetary structure and evolution.

James Webb Space Telescope Studies of Dark Energy [PDF]

, 2010
The Hubble Space Telescope (HST) has contributed significantly to studies of dark energy. It was used to find the first evidence of deceleration at z=1.8 (Riess et al.

High-precision stellar limb-darkening in exoplanetary transits [PDF]

, 2017
Characterization of the atmospheres of transiting exoplanets relies on accurate measurements of the extent of the optically thick area of the planet at multiple wavelengths with a precision $\lesssim$100 parts per million (ppm).

UV–Vis Spectra of Carbonic Acid: Rationalizing Experimental Redshifts between Monomer and Bulk based on (H2CO3)n Calculations

ChemPhysChem, Volume 26, Issue 18, September 19, 2025.
In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.

Improved Empirical Backgrounds for JWST NIRISS Image/Wide-field Slitless Spectroscopy Data Reduction

The Astronomical Journal
The Near Infrared Imager and Slitless Spectrograph (NIRISS) on the James Webb Space Telescope (JWST) is a versatile instrument for collecting imaging and wide-field slitless spectroscopy (WFSS) data for surveys of galaxy clusters, emission-line galaxies,

Slow Rotation for the Super-puff Planet Kepler-51d

The Astrophysical Journal Letters
Super-puffs are low-density planets of unknown origin and composition. If they form by accreting nebular gas through a circumplanetary disk, one might expect super-puffs to be spinning quickly. Here, we derive upper limits on the rotational oblateness of

Hubble Space Telescope and James Webb Space Telescope [PDF]

Over the past 20 years the Hubble Space Telescope has revolutionized our understanding of the Universe. Most recently, the complete refurbishment of Hubble in 2009 has given new life to the telescope and the new science instruments have already produced ...
