A more recent hypothesis proposes that Venus's ashen light is a form of transient aurorae or airglow.
Notes on verification
Confirmed as a genuinely proposed and recognized hypothesis in peer-reviewed literature (Levine 1969; JBAA 2014), and cited by other secondary sources. However, it remains one of several competing explanations, with some evidence (e.g. 1990 Icarus study) casting doubt on the auroral correlation, so scientific consensus is not settled.
