Une planète semblable à la Terre pourrait se cacher dans notre système solaire
"Dans une étude parue le 25 août dernier au sein de la revue scientifique The Astronomical Journal, deux scientifiques japonais prédisent l’existence d’une planète semblable à la Terre, cachée dans notre système solaire, au cœur de la ceinture de Kuiper."

Where is Babel Rock?
The #USGS #BlueHills #quad #bedrock map and a #Quincy #Massachusetts #historical #map show Babel Rock overlooks a pond from just north of a bend in #Wampatuck Rd. I have been on that rock, and it's #diabase, a #mafic #intrusion into the Quincy #pluton. But the USGS #topographic quad & derivatives e.g. #GoogleEarth show it adjacent to the #BunkerHill #quarry (source of the #granite for the monument in #Boston).
Should a correction be proposed to USGS? Advice welcomed.

We walked around #Cohasset, #Massachusetts #USA in the unusually warm (50 F, 10 C) “winter” weather here in #NewEngland. This is an (absurdly) prosperous #coastal community just south of #Boston. The walk included lovely views across coves and marshes (including #invasive Phragmites australis and #peat under #native #Spartina), as well as nice exposures of the > 600 Ma #Dedham #granite, the #pluton coring most of the #Avalon terrane in this area.

"There are no firm details on Linux support just yet, but Microsoft already uses Linux with Pluton in its Azure Sphere devices, so it’s likely to be available whenever these chips ship."
