[edit]This page [http://www.eastbayastro.org/2001/0301/r0301-2.htm The Paradoxical Ashen Light of Venus] seems to have similar content, is it too similar? Rwlaschin (talk) 19:45, 14 March 2008 (UTC)
It is only detectable by human eyes? That doesn't make sense. —Preceding unsigned comment added by 71.202.211.35 (talk) 07:09, 11 September 2009 (UTC)
- Yeah, that bit's BS. Venus missions haven't provided optical night-sky coverage for long enough, seemingly. Fixed that nonsense, and added a citation! YhnMzw (talk) 17:19, 8 November 2009 (UTC)
the name
[edit]Who named the Ashen light, and why? —Tamfang (talk) 07:14, 16 May 2011 (UTC)
Earthshine?
[edit]Could the Ashen Light literally be earthshine, light from the Sun reflected by the Earth to Venus, then back to observers on Earth? As seen from the night side of Venus (above the clouds), when Venus is roughly between the Earth and the Sun, the Earth must be an absolutely brilliant object in the Venusian sky. If the clouds consist of droplets that retro-reflect light in the direction from which it has come, a lot of light would be reflected back to the Earth. Would this be enough to account for the Ashen Light? Maybe.
If this is true, then the Ashen Light would not be visible from a direction substantially different from that of the Earth.
Claims by LEMMiNO video
[edit]In LEMMiNO's recent video (timestamp 11:45), he makes the claim that Athanasius Kircher may have described the Ashen Light in 1638, 5 years prior to Riccioli. I don't think it should need to be said, but this should probably be verified by professionals before being added to this page. I've seen the vexing quality that edits asserting YouTuber claims have too many times. Horizons 1 (talk) 19:09, 30 March 2022 (UTC)
- @Horizons 1 not just that but the reference lists the original book, where there is no explicit date mentioned 75.110.65.216 (talk) 14:47, 5 November 2024 (UTC)
Parker Solar Probe
[edit]As reported here, PSP has seen visible light coming from the night side of Venus. Could this be the infamous ashen light? They don't know, but they do discuss the possibility in the Conclusions section. Worth a mention? 78.146.61.195 (talk) 21:58, 12 September 2022 (UTC)
