IAU 100: A pale blue dot !

D'accord mais:
Au chaitre III -10 il y a ceci:
c’est bien peu de chose que le misérable coin de terre[46] où l’on vit. C’est peu de chose même encore que cette renommée qui nous survit, prît-on celle qui dure le plus longtemps
Citation en anglais attribuée par Carl Sagan à Marcus Aurelius:
The entire Earth is but a point, and the place of our own habitation but a minute corner of it.

En effet.....Mais où trouver la version originale des quelques phrases de son livre IV ?

Initiative de MIRA pour célébrer les 30 ans du Pale Blue Dot; deux photos de vous; une de 1990, une de 2020 (aïe....) et un texte.... La sonde était en 1990 à 5h30 lumière de la Terre et en 2020 à 20h30 lumière.

Happy New Year!

You are receiving this email as you were one of the registered event organizers for IAU100's Moon Landing 50 ( www.moonlanding50.org ) and/or Astronomy Day in Schools ( www.iau-100.org/astro-day-schools ) global projects. My name is Bethany Downer and I was the global event coordinator for these initiatives, and I'm delighted to welcome you to take part in the final IAU100 global event that will conclude the International Astronomical Union's centenary celebrations: The Pale Blue Dot - Astronomy for Global Citizenship and Environmental Awareness.

After one year of looking at one hundred years of milestones in astronomy with IAU100, and over 5000 astronomy outreach activities conducted in 140 countries worldwide throughout 2019, let’s look back at us, Planet Earth, and how astronomy shows us the place of our home planet in the universe and can help us address global challenges on and around 13-20 February 2020.
​
The 30th anniversary of the iconic Voyager-1 Pale Blue Dot image will be celebrated around its anniversary on 14 February 2020. This iconic image illustrates the unique astronomical perspective on Earth: when observing our home planet from space, national boundaries disappear and the fragility of Earth becomes evident. This perspective is pertinent to remind ourselves to treat each other with kindness and take care of our home planet together.

IAU100 is inviting everyone to participate in this final global project during and around 13-20 February 2020 to recognise the significant anniversary by organising activities around the topics of global citizenship and environmental awareness. In particular focusing on how astronomy can help us address today’s global challenges.

The Pale Blue Dot global project intends to facilitate event organizers to use astronomy as a tool to initiate conversations in their respective communities about global citizenship and uniting people from all cultures and backgrounds. Furthermore, this initiative aims to inform audiences about climate change by using the perspective of astronomy to remind the public that the Earth is our only habitable home.

A project page has been set up for interested event organizers, where collection of Resources and Activity Ideas have been compiled to facilitate the organisation of activities for the IAU100 Pale Blue Dot initiative that encourage the project’s themes of global citizenship and environmental awareness: www.iau-100.org/pale-blue-dot

I welcome you to register your event under the category “Pale Blue Dot” using this form: www.iau-100.org/event-registration

Please feel free to get in touch with any questions you may have. On behalf of the IAU100 Secretariat, we thank you for supporting and participating in the IAU100 celebrations with us. Best regards,

Voici une photo du livre de Carl Sagan Pale Blue Dot (1994) (acheté avant l'ère d'internet).
Curieusement, il ne parle du "Pale Blue Dot" qu'au début du livre. L'image d'il y a 30 ans fut un peu décevante à cause de l'éclat du Soleil et d'un rayon de soleil pile sur la Terre. Ce n'est pas vraiment de la fragilité de la Terre qu'il est question (comment l'estimer à partir d'un point?) mais plutôt de notre insignifiance.
Je sais que l'IAU argumente sur sa fragilité (comme c'est d'actualité) mais....
Sagan (chapitre 1 You are here) cite l'empereur romain Marc Aurèle (méditations livre IV en 170 après JC) :
Car la terre tout entière n'est qu'un point; et ce que nous en habitons, quelle étroite partie n'en est-ce pas encore ? Et dans ce coin, combien y a-t-il d'hommes, et quels hommes ! Qui célébreront tes louanges ?

(Ce serait génial de retrouver la version latine..mais bon).
