Pollution plastique: cette "plastisphère" qui menace les écosystèmes d'eau douce

Mise en évidence d'abord dans l'océan, la "plastisphère" est la communauté de microbes qui se forme autour des fragments de plastique. Sa présence au sein des...

Je cherche pour ma grand-mère un planisphère politique récent, de grande taille (genre A0), à dérouler ou déplier sur la table pour suivre l'actualité. Dans l'idéal avec une projection qui respecte un peu la taille des pays, mais qui ne soit pas trop exotique.
Est-ce que vous connaissez un service, un collectif ou un prestataire qui fait ce genre de cartes, avec une mise à jour récente ? Peut-être même à partir des données OpenStreetMap ?

#OpenStreetMap #planisphere #print

And last is some #lunar literature.

#Moon observers Guide by Peter Grego is a must have book for observers of the moon. Very readable & contains lunar slices that show what will be on the #terminator each day.

The Moon Map is another item from my childhood & almost as old as the #Planisphere & purchased for the princely sum of £1.50!

This map taught me the lunar surface and I would pour over it for hours as a child, another #astronomy totem that has been everywhere with me

#Astrodon

Moving the #planisphere to after midnight I can see that the #moon, over on the ecliptic line in #Gemini is still to the east of the meridian but a lot higher (so more sky glow!) and Aries and Perseus are now in the prime observing area of my sky.

So this gives me a region of sky to consider when I turn to my more detailed star charts. But before I do that, given it won't be a #darksky evening I should have a look at #planets and see what options I have there too... #Astrodon

It is a simple device, set time to date & there is your sky. Yes there are apps, but this requires no power, doesn't ruin your night vision and is very waterproof - essential in the damp #astronomy of the #UK

So here is the sky for about 9-10pm on Saturday, same as the sky at 3am end of August (fun #Planisphere fact).

This shows me Pegasus, Andromeda, Pisces & Cassiopeia look like good target constellations in the earlier part of the session...good altitude & away from the moon #Astrodon

Right then after a real world break (aka work) back to #astronomy planning!

My next stage is to think about what will be where at what height and when. For this I use my oldest astronomy possession...my 37 year old #Planisphere.

8 year old me badgered his parents for one of these and in an age before the internet that meant trawling the bookshops of Hertfordshire. Eventually my long suffering Mum & Dad found one in Ware and this has been my constant astronomy companion ever since. #Astrodon
