A fact from Hesperian appeared on Wikipedia's Main Page in the Did you know column on 16 July 2011. The text of the entry was as follows:

Did you know... that during the Hesperian, Mars changed from a wet, warm world to today's dry, cold, and dusty planet?

A record of the entry may be seen at Wikipedia:Did you know archive/2011/July.

Catastrophic?

"characterized by widespread volcanic activity and catastrophic flooding" - can something be a catastrophe if there is no-one around to be adversely affected by it? (AFAWK.) I thought that 'catastrophe' specifically meant 'bad' rather than just 'had a significant effect', but perhaps geologists use it differently. --86.150.60.188 (talk) 07:57, 16 July 2011 (UTC)[reply]

In geology the word usually means sudden and rapid as opposed to slow and gradual (i.e., happening in a geologic instant rather than over very long periods of time). I think the use goes back to the early days of the science when the primary debate was catastrophism vs. gradualism. Schaffman (talk) 10:22, 8 August 2011 (UTC)[reply]

Can we factor out the timeline diagram for easier sharing

The timeline graphics is drawn here and in the other two articles Noachian and Amazonian - How should we make it a shareable resource ? - Rod57 (talk) 10:33, 20 February 2019 (UTC)[reply]

Internal Link For Pre-Noachian Links to Noachian

On the Infobox the hyperlink for the Pre-Noachian redirects to the Noachian.

I couldn't rectify this issue myself so I wanted to ask if an editor could fix this for me, it already inconvenienced me, I'd hate for that to happen to someone else browsing Wikipedia.

The article for the Amazonian (Mars) also has this issue, and the Noachian doesn't even have a hyperlink for the Pre-Noachian 2600:4041:3CAD:8B00:A937:31FD:8632:79B2 (talk) 05:22, 31 August 2025 (UTC)[reply]
