Water Earths in the Near-Infrared
This artist's concept shows what a fiery hot star and its planetary companion might look like close up in infrared. Credit: NASA/JPL
A team of researchers supported by the NASA Astrobiology Institute have examined the potential of detecting oceans on terrestrial-sized exoplanets by using observations in the near-infrared (NIR). Previously, it had been suggested that oceans on distant, rocky worlds could be identified by observing variabilities in scattered light. However, the team suggests that such observations could be difficult due to atmospheric scattering. On Earth, this scattering is reduced at certain wavelengths in the NIR.Based on scattering in Earth’s atmosphere, the team modeled two wavebands of light in the NIR that could be useful in...
