When it is solicited, D.19 Habitable Worlds Observatory System Technology Demonstrations and Mission Architecture Studies (HWOTAS) will seek industry-led proposals to carry out (1) system-level critical technology demonstrations for ultra-stable […]
Polarized Signatures Of The Earth Through Time: An Outlook For The Habitable Worlds Observatory
The search for life beyond the Solar System remains a primary goal of current and near-future missions, including NASA’s upcoming Habitable Worlds Observatory (HWO).
Optical Design Options For Pollux: UV Spectropolarimeter Project For The Habitable Worlds Observatory
Pollux is a project of UV spectropolarimeter proposed as a European contribution for the planned NASA-led Habitable Worlds Observatory.
The Pale Blue Dot: Using the Planetary Spectrum Generator to Simulate Signals from Hyperrealistic Exo-Earths
Simulating realistic observations of exoplanet atmospheres requires consideration of several physical, astronomical, and technological aspects. The composition and physical structure of an atmosphere has to be modeled using three dimensional […]
Detectability Simulations of a NIR Surface Biosignature on Proxima Centauri b with Future Space Observatories
Telescope missions are currently being designed which will make direct imaging of habitable exoplanets possible in the near future, and studies are needed to quantify the detectability of biosignature features […]
Simulated Performance of Energy-resolving Detectors Towards Exoplanet Imaging with the Habitable Worlds Observatory
One of the primary science goals of the Habitable Worlds Observatory (HWO) as defined by the Astro2020 decadal survey is the imaging of the first Earth-like planet around a Sun-like […]
ESCAPE Project: Investigating Active Observing Strategies and Post-processing Methods for Exoplanet High-contrast Imaging with Future Space Missions
The search for biosignatures in potentially habitable exoplanets is one of the major astrophysics’ drivers for the coming decades, and the prime science goal of the HWO NASA mission, a […]
Ultraviolet Technology To Prepare For The Habitable Worlds Observatory
We present here the current state of a collection of promising ultraviolet technologies in preparation for the Habitable Worlds Observatory.
X-ray Emission of Nearby Low-mass and Sun-like Stars with Directly Imageable Habitable Zones
Stellar X-ray and UV radiation can significantly affect the survival, composition, and long-term evolution of the atmospheres of planets in or near their host star’s habitable zone (HZ).
