When the title of a paper - "Direct measurement of decimetre-sized rocky material in the Oort cloud" - is obviously too obvious ... and the journal that published it puts it on the cover and gets the astronomy dead wrong: https://twitter.com/meteordoc/status/1639297365474529281. Anyway, the paper as such is quite interesting and you can read it open access at https://arxiv.org/abs/2212.06812 #meteors #OortCloud #SolarSystem

Scholz's Star (WISE designation WISE 0720−0846) is a dim binary stellar system 22 light-years (6.8 parsecs) from the Sun, that passed through the Solar System's Oort cloud roughly 70,000 years ago.

Each SMBH is several 100million #solar masses, but are only 200-2000AU (0.003- 0.03 light-years) apart. For scale, they are closer to each other than the #OortCloud (part of our own #solarsystem) is to the #sun. Despite their incomprehensible size, a single orbit only takes 2 years.

The last time the comet passed Earth was during the #UpperPaleolithic period, when #Neanderthals still roamed Earth."

i’ve dug BX’s RETURN OF THE GOLDEN MEAN (w/verdeaux on guest #synth) for years, but only recently got w/this gentler, dorkier sequel—taking ‘#cosmic’ label more literally not seriously, xolotl conjures ancient-future rituals in a now-familiar astro-#BerlinSchool idiom. now with major keys! highlight: ‘prophecy’ extends the #OortCloud logic of GOLDEN MEAN’s ‘descending phases’ for 25 minutes of darkstarlit drift/dream.
