Here are more detailed maps of those sites, using much smaller ellipses than in our first map. The navigators were more confident so the uncertainty was reduced. Ellipse 3 (top left... ignore the A, B etc, letters) - is close to the Pathfinder site used much […] [Original post on mastodon.social]

Danish national anthem sings that Denmark will last as long as the beech trees are reflected in the blue waves of the sea. I have often wondered which we lose first: beech trees or #sealevelrise. This from @AarhusUni et al suggests it will be the trees […]

I often think it is a disservice that climate change activism has focused on suffering and changes "over there" - our natural environment and cultural life will be as impoverished just as much by loss of familiar species and traditions as the Inuit hunting narwhal or Pacific Islanders forced to […]

Up late reading about this freaky little mess of a clade that somehow colonized five continents despite never leaving their holes

#Tugtupite is our second sodalite-structure (after #Haüyne). FInch et al. (2016) investigated the sources of color from point defects, bonds, and coordination in the #sodalite cage structure. Tugupite is different, due to the beryllium substitution by also […] [Original post on fosstodon.org]

It's hard to believe now how little was known about Mars when that first map was complied. Mariner 9 changed that in 1971-72. Its job was to map the planet's features, and this is when the 'Wonderworld' was revealed - the volcanoes, canyons, channels etc. we […] [Original post on mastodon.social]
