[7] Data collected from the Hubble and Spitzer Space Telescopes have provided evidence of titanium oxide and small amounts of water within the planet's atmosphere.

[8] Further analysis using higher-resolution spectra has revealed the presence of ionized elements such as lithium, sodium, magnesium, calcium, manganese, potassium, and iron.

[14] In April 2024, it was suggested that a glory effect in the atmosphere of WASP-76b might be responsible for the observed increase in brightness of its eastern terminator zone.

[14] By 2021, the controversy surrounding the presence of iron condensation had been resolved by demonstrating that the observed signal may also be due to temperature variations between different parts of the planet.

[19] Based on planetary atmospheric circulation models for WASP-76b, it is suggested that dense cloud layers composed of aluminum oxide, neutral iron, or magnesium orthosilicate may form.
