We present the first panchromatic JWST transmission spectrum of an ultra-hot Jupiter, combining NIRISS and NIRSpec observations to constrain KELT-7\,b's atmospheric properties. We show evidence for ch...

The Habitable Worlds Observatory (HWO) will provide the first opportunity to directly image and spectrally characterize terrestrial exoplanets in the habitable zones of nearby stars. Maximizing its sc...

The Hubble Space Telescope inaugurated the era of exoplanet atmospheric characterization. While the James Webb Space Telescope has largely taken up the mantle of infrared atmospheric characterization,...

An out-of-this-world weather report from NASA’s James Webb Space Telescope reveals how clouds move across a giant planet hundreds of light-years from Earth

We present high-resolution NUV observations from Hubble Space Telescope's (HST) Space Telescope Imaging Spectrograph (STIS) data for the hottest known gas planet, KELT-9b. Observations were collected ...

The Trump administration is breaking up the National Center for Atmospheric Research, taking aim at one of the world's leading climate research labs.

The present-day bulk elemental composition of an exoplanet can provide insight into a planet's formation and evolutionary history. Such information is now being measured for dozens of planets with sta...

Exocomp is a toolkit with functions and utilities for normalizing measurements from different retrievals of exoplanets and brown dwarfs. - jlothringer/exocomp

The Chesapeake Bay Area Exoplanet Meeting brings together all lovers of exoplanets and related science from the DC area and beyond. This series of one-day meetings enable the sharing of ideas in an in...
