Has Gaia Data Resolved the tension in measurements of the Hubble Constant? Can Pluto be seen in city lights viewing?

Greetings from Palmia Observatory

Well here we are in another busy week.  We have upcoming conferences and also a chance to do some astrometry, which is now helping to maybe resolve the tension between two estimates of the Hubble Constant, in our search for finally trying ourselves to (though not yet) get an image of Pluto.

Astronomers' brains wanted: Night of the Living Dead; OC Physicists to search for vampire emanations; Primordial Black Holes, Dark Matter, Neutrinos and other deeply hidden things

Greetings from Palmia Observatory

Last week we talked about the search for ghostly particles from nuclear power plants and this week we continue exploring some illusive deeply hidden things.

Saturn, Jupiter and Moon under the stars with jazz; Hunting for Ghosts from Nuclear Reactors; Using opaque liquids rather than transparent; Sizes of Black Holes; Global CO2 and GDP; Robots and interactions in the Observatory

Well this week the scope remained packed up, but at least we spotted Saturn, Jupiter and the Moon close together and recorded the view with the iPhone.

Hooray, watch Elon go from Brownsville, TX!; Hooray, our eyeballs, but not our cameras saw the JWST!; More great free Coursera

Well we have had some rain and cloudy weather that cancelled this month's OCA star party, but looking up at the sky is what Elon Musk did in his annual review of the Starship and Super Heavy progress.

Distinctive Voices lecture on Human Lunar Exploration; Sunspot cycle and orbital variation effects; ASAS-SN and search for Gravitational Waves from core collapse supernovas

Greetings from Palmia Observatory

Well I am just getting into the 3rd section of Sean Carroll's "Something Deeply Hidden", where he talks about the emergence of spacetime from quantum entanglement, so we have to pause and let that ferment until next time, but for now let's comment on Lunar Exploration, Solar sunspot and orbital effects, ASASSN surveys and search for gravitational waves from core collapse supernova.
