Incredible First Discoveries From NASA’s New Exoplanet-Hunting Spacecraft: TESS
“The ultimate goal of TESS is to find possible Earth-like worlds, and star systems which may house rocky, potentially habitable worlds. Because TESS is optimized to scour the stars nearest to us, it’s greatest finds will be among the first targets for future, more powerful observatories that can not only detect these worlds, but measure their atmospheric contents. If we get lucky, some of those worlds might house molecules like water, methane, carbon dioxide, or even oxygen in their atmospheres.
It won’t be a slam-dunk that these worlds are inhabited, but TESS takes us one step closer towards finding the nearest worlds that might be humanity’s greatest hope for finding life outside of our own Solar System. The worlds we’ve found so far are absolutely fascinating, and just a few months into its primary mission, TESS is easily meeting even the loftiest expectations for it. By time the James Webb Space Telescope launches, TESS should provide us with many worlds that just might be the best place to look to take our next great leap towards our ultimate goal: finding an inhabited world.”
NASA’s exoplanet-hunting satellite, TESS, was launched in April of 2018, began taking data in July, and released their first data to the world last month. That data contains around 300 candidate exoplanets, and the first eight of them have already been confirmed. From worlds so hot that they might have liquid rock on their surface to a solar system so strange we’ve never found anything like it, these are the first highlights.
