“To me this implies that understanding exoplanet atmospheres is definitely an very challenging observational field,” he stated. “We should be thoughtful in the way we design instruments to identify and understand exoplanet atmospheres. So we should be patient. I truly believe that this lengthy time lag is going to be repeated, likely with an a lot longer time scale, for that atmospheres of temperate terrestrial planets.”
Seager states planets like WASP-19b possess a “treasure trove” of features that are really helpful to look at.
You may still find lots of steps before that moment, because the JWST won’t launch before the latter 1 / 2 of 2018, after which will have to time scan the skies. However these WASP-19b answers are nevertheless encouraging.

“People can make claims about these atmospheres, many will finish up being correct, many will finish up not correct, and it’ll take considerable time for that field to stay out, to fix itself. It will likely be exciting, although not obvious-decline in the very first findings,” stated Fortney.
Jonathan Fortney, a specialist in exoplanet atmospheres at UC Santa Cruz, really predicted that metal oxides would trouble nearby hot-Jupiters. But he admits breakthroughs within the field is going to be slow for the time being since most “general use” instruments can’t get the amount of detail needed for terrestrial exoplanetary atmospheric analysis. Although the FORS2 tool continues to be really effective within this project, it had been installed before we’d even discovered exoplanets while using transit method.
“It’s a really nice result,” stated Sara Seager, a professor of planetary sciences and physics at Durch, within an email. “I can tell it is really an outstanding achievement from the ground-based telescope and nature delivered us an incredible hot planet atmosphere. To date, a lot of planets are actually “clouded out” so we can’t observe any spectral features. [Titanium Oxide] appears obscure, but is really a really strong absorber—kind of just like a skunk smell, merely a small amount can produce a difference.”
