When astronomers analyzed the spectrum, they found the telltale "fingerprint" of sodium.

I would guess that this, combined with the proximity to the star and the temp reported in the article, would indicate that sodium exists as a gas on this planet?

   If I recall correctly, sodium vapor lamps are orange in color.
   The planet might look like a cross between Jupiter and
