The angry astronaut is very level headed.
Good, recent video of a green fireball and an #orb rising from the landing.1. #3iatlas was a techno signature
2. The fireballs are anomalous and don't match existing asteroid showers
3. Hundreds of #uap / #ufo observed and filmed around volcanos
The "it's a satellite" 'debunk' is propesterous.
There were no satellites (folks checked).
And the fact Avi said that means he got got to.Notably:
A re-entry vehicle and a "fireball" look nearly identical. The "explosion" could be a break burn.
Esp. if the crew is not biological and can take the g, or as evidenced they don't care about g.The Los Angeles green fireball was immediately seen before the "Aliens in the carpark" a couple of years ago, complete with police 911 calls, men with guns, men in black and authorities installing cameras.
This looks like a classic invasion scenario, our authorities are aware of it (which notable explains things going to shit).
This could well be the 2027 event that is a hard boundary earth authorities are constrained by.We were allegedly given a date to prepare by, hence the rapid #disclosure , because we left it to the last minute.
There will be a lot of folks freaking the fuck out.

3I/ATLAS: Gemini Observatory Captures Exocomet On Its Approach To Earth And It Is Glowing Green; Here’s Why
-
Finally an RGB image of comet #3IATLAS from images taken by #GeminiNorth during the 26 November #shadowTheScientists session: https://noirlab.edu/public/news/noirlab2532/ - the coma has become bluer due to more gas emission. Also published today: an X-ray image by XMM-Newton at https://www.esa.int/ESA_Multimedia/Images/2025/12/XMM-Newton_sees_comet_3I_ATLAS_in_X-ray_light with explanations in http://www.cbat.eps.harvard.edu/iau/cbet/005600/CBET005646.txt which also contains more 3I news.
Meanwhile the paper https://iopscience.iop.org/article/10.3847/2515-5172/ae2915 claims an upper limit for 3I's nucleus diameter of only some 750 meters from the measured non-gravitational acceleration (NGA) parameters: that would be waaay more stringent than the 5.6 km upper limit from early Hubble observations reported in https://iopscience.iop.org/article/10.3847/2041-8213/adf8d8 (where also a lower limit of 440 meters is stated).

And here is a recording of the #ShadowTheScientists live observation of interstellar comet #3IATLAS with #GeminiNorth a few hours ago: https://www.youtube.com/watch?v=cW0chiPZyYM

And here is what comet #3IATLAS looks like for the #geminiNorth Integral Field Unit (IFU) taking numerous spectra from points across the coma - from #ShadowTheScientists
-
What a #GeminiNorth #3IATLAS spectrum looks like - as raw as it gets, from the #shadowTheScientists session. See https://www.astronomerstelegram.org/?read=17503 for a pre-perihelion spectrum.

The #GeminiNorth telescopes is observing the interstellar comet #3IATLAS right now: here is the acquisition image from moments ago, spectra to be taken now - from the #ShadowTheScientists session.

Selfie aus dem Reinraum: Dreharbeiten für Sat1regional führten ein Kamerateam jetzt in einen unserer Kontrollräume. Von dort hatten unsere Gäste einen guten Blick in unsere Reinräume. Dort arbeiten Wissenschaftler*innen und Ingenieur*innen in Reinraumkleidung und unter saubersten Bedingungen an Weltrauminstrumenten.
Eines dieser Instrumente ist das Submillimetre Wave Instrument (SWI) der ESA-Mission JUICE. Während das eigentliche Instrument an Bord von JUICE in den vergangenen Wochen den interstellaren Körper 3I/ATLAS beobachtet hat, ist die Ersatzeinheit am MPS zuhause.
Der Beitrag über die 3I/ATLAS-Beobachtungen von SWI lief in den Regionalnachrichten von Sat1 Regional Norddeutschland.
