![Life 2.0 mission concept and simulated biosignature spectroscopy. The distributed array observes a common target with many one-meter telescope modules. The example spectra illustrate UV-optical atmospheric signatures and the simulated recovery of O₃, O₂, and H₂O after calibrated spectral co-addition. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Life-2.0.jpg?resize=1200%2C719&ssl=1)
[astro-ph.IM] Answering the question “Are we alone?” requires atmospheric spectroscopy of nearby terrestrial planets. For an Earth–Sun analog, even the strongest transmission signals are expected to be of order 1 […]
