Some U.S. astronomy is still alive ... the first of five press conferences from the #AAS246 meeting in Alaska is now streaming on https://www.youtube.com/watch?v=K6sPNlpIurg - see https://aas.org/meetings/aas246/press-kit#Mon_am for the topics.

With the #AAS246 presser number 3 came the press releases https://www.stsci.edu/contents/news-releases/2025/news-2025-018 (Moons of Uranus Surprise Scientists in NASA Hubble Study) and https://webbtelescope.org/contents/news-releases/2025/news-2025-125 (Frigid Exoplanet in Strange Orbit Imaged by NASA's Webb) and the paper "Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system" already covered in https://scicomm.xyz/@cosmos4u/114660217108691128 with the press release https://www.tcd.ie/news_events/top-stories/featured/silicate-clouds-discovered-in-atmosphere-of-distant-exoplanet/ (Silicate clouds discovered in atmosphere of distant exoplanet).

With the 4th #AAS246 press conference come the press releases #PUNCH and #CODEX sitting on the ISS. While the corona shape predictions for the 2024 total solar eclipse were published in https://www.predsci.com/corona/apr2024eclipse/home.php

The presentations at the 2nd #AAS246 presser were about the papers https://iopscience.iop.org/article/10.3847/2041-8213/adc911 (Discovery of the Seven-ring Polycyclic Aromatic Hydrocarbon Cyanocoronene (C24H11CN) in GOTHAM Observations of TMC-1, also https://public.nrao.edu/news/cosmic-chemistry-breakthrough-largest-aromatic-molecule-found-in-deep-space/), https://arxiv.org/abs/2506.05575 (A map of the outer gas disk of the Galaxy with direct distances from young stars, also https://www.uah.edu/news/items/uah-researcher-unveils-new-map-of-milky-way-galaxy-in-atomic-hydrogen-revealing-its-clumped-flocculent-nature-for-first-time) and https://iopscience.iop.org/article/10.3847/1538-4357/adbbd9 (Surveying the Giant H ii Regions of the Milky Way with SOFIA.

The PI of #PUNCH and a composite image from the images by the five satellites, during the ongoing #AAS246 press conference: the stitching already works quite well and will improve further, but already now halo CMEs can be followed to a larger angular size than ever before and until hours before Earth impact.

And here is (a recording of) the fifth and final #AAS246 press conference about "Recent and Upcoming Discoveries in the Broader Universe": https://www.youtube.com/watch?v=nf9X5kntlYc - topics at https://aas.org/meetings/aas246/press-kit#Wed_am
