Researchers Create Model of Lifeless Earth to Aid in Exoplanet Life Search

• Researchers have created a model of a lifeless Earth at the University of Washington.
• The model simulates Earth's atmosphere and interior planetary processes without life.
• This tool can reproduce Earth's modern habitable state without including biological influences.
• The model will help identify false positives when searching for life on exoplanets.
• The model will be particularly useful if the Habitable Worlds Observatory is launched.
