The First Complete Picture Of (Gas) Planet Formation In Action
[Max Planck Institute for Astronomy] Over the past decades, astronomers have reconstructed a fairly complete scenario for planet formation, from minute dust motes clumping together to the emergence of rocky […]

Discovery Of Radio Emission From The Exoplanet β Pictoris b
[astro-ph.EP] Planetary magnetic fields shape atmospheric escape, mediate interactions with stellar winds, and encode information about planetary interiors, yet they have not been directly measured for planets beyond the Solar […]

Inside the Eirenesphere: The Interplay of Porosity, Heat Flux and Mineralogy in Exoplanetary Aquable and Habitable Layers
[astro-ph.EP] The classical circumstellar habitable zone restricts the search for life to planetary surfaces where stellar irradiation sustains liquid water, overlooking vast subsurface environments.

Characterization Of Planetary Systems With Astrometry
[astro-ph.EP] Astrometry is the oldest method used to search for extrasolar planets. This technique provides key information about a planetary system, like the true mass of planets and its three-dimensional […]

Possible Observational Survey Strategies to Maximize Exoplanet Yields: A Report from the Survey Strategies Task Group in the Exoplanet Science Yields Working Group
[astro-ph.EP] We present a variety of possible observational sequences from planet detection to characterization (i.e., survey strategies) for the initial exoEarth detection and characterization survey phase of the Habitable Worlds […]
The Search for Earth 2.0
Another Earth could be out there. How do we find it? Join Dr. Jessie Christiansen, Chief Scientist of the NASA Exoplanet Science Institute, for “The Search for Earth 2.0: Why […]

The Science Potential of Characterizing Gas Giant Exoplanets with HWO
[astro-ph.EP] With the ability to directly image Earth-like exoplanets and search their atmospheres for biosignatures, the upcoming Habitable Worlds Observatory (HWO) will also collect high signal-to-noise ratio (S/N) reflected-light photometry […]
