🌍 Is there a "second Earth" out there? This question is at the heart of a feasibility study involving Stefan Kimeswenger from the University of Innsbruck. The team tested a setup designed to analyze #exoplanets for molecules such as water and oxygen. A giant flower-shaped satellite could serve as a β€œsunshade” in space.

Sunshade helps in the search for a second Earth

An international research team including Stefan Kimeswenger, astrophysicist at the University of Innsbruck, has tested a new approach to studying Earth-like exoplanets. The idea is to combine a large, earth-based telescope with a "sunshade" orbiting in space.

A. Quirrenbach reporting at #ag2025goerlitz about the status of the #HabitableWorldsObservatory, the next next thing for NASA after Roman: a 10% contribution by ESA (as for HST and JWST) is likely - and Germany could deliver something important, like a separate #StarShade spacecraft for stellar coronography on steroids. Something to dream about for the 2040s ...
Dynamically Stable Large Space Structures via Architected Metamaterials

Exoplanet exploration has taken off in recent years, with over 5500 being discovered so far. Some have even been in the habitable zones of their stars. Imaging one such potentially habitable exoplanet is the dream of many exoplanet hunters, however, technology has limited their ability to do that. In particular, one specific piece of technology … Continue reading "Dynamically Stable Large Space Structures via Architected Metamaterials"
