None of the NASA s/c images of #3IATLAS shared at the presser come even remotely close in beauty - and obvious detail - to the current best ground-based images ... like this one by Michael Jäger and Gerald Rhemann with a 12-inch reflector taken this morning: https://www.facebook.com/photo/?fbid=2282405328942953

All the NASA s/c images of #3IATLAS shared today (and some more) can be found at https://science.nasa.gov/solar-system/comets/3i-atlas/comet-3i-atlas-image-gallery/ now - including this spectrum from the Imaging Ultraviolet Spectrograph on MAVEN taken on 28 September, showing hydrogen emitted from different sources, namely the comet (dim spot on the far left), hydrogen from Mars (bright emission on the right), and hydrogen flowing through our solar system between the planets (dim emission in the middle).

The #3IATLAS NASA presser has begun: https://www.youtube.com/watch?v=A55SUq2eDXg - so far they've shared this HiRISE image from Mars orbit, but they've listed many NASA s/c which have observed it.
Interstellar comet #3IATLAS webcast double feature today (19 November): first at 4:15 UTC on https://www.youtube.com/watch?v=krU8gN-J9gY the next attempt of a live observation from Italy (the first one had been clouded out) - and then at 20:00 UTC on https://www.youtube.com/watch?v=A55SUq2eDXg a NASA press conference with spacecraft observations.
NASA will host a live event at 3 p.m. EST, Wednesday, Nov. 19, to share imagery of the interstellar comet 3I/ATLAS collected by a number of the agency’s missions. The event will take place at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. https://www.nasa.gov/news-release/nasa-to-share-comet-3i-atlas-images-from-spacecraft-telescopes/ #3IATLAS

I wish #Flipboard.com would update their Mastodon version, so we could quote their posts. Flipboard.social (a different, vanilla Mastodon server) already did.
Anyhow, hereby two good YT video's about #3iAtlas

Aliens or not, #3iAtlas is fckng interesting! Watch the videos and the hashtag.
3I/Atlas isn’t deep space aliens and didn’t ‘change color’

INTERSTELLAR COMET 3I/ATLAS reemerged from behind the Sun and is visible again in the pre-dawn sky in Virgo.
A new Nov. 8 image from Michael Jaeger and colleagues shows four or five tails, including a narrow jet aimed toward the Sun. The comet is exactly where it should be, following the same trajectory as before perihelion. Spaceweather.com is requesting confirming photos.

In the comments of a YouTube video about 3I/ATLAS:
"It's kinda wild to think that for all of human history we never spotted a single interstellar object… and then in just the past few years we suddenly get Oumuamua, Borisov, and now 3I Atlas. It almost feels like the universe was waiting until we had the tech to finally notice."
Dude, you're so close
This is a reminder that the raw NASA Mars spacecraft images of 3I/ATLAS were publicly released more than a month ago.
What has been delayed due to the government shutdown is official processed versions and associated commentary.

There is a super faint smudge where comet 3I/Atlas should be. The new orbit parameters in Stellarium are a pretty good match. 🔭 #3iatlas

☄️ Two Spacecraft Orbiting Mars Just Spotted the Mysterious Interstellar Visitor
｢ Deputizing the Mars spacecraft to try observe the comet was a literal shot in the dark, since both of their cameras are designed for imaging Mars’ well-lit surface, and not tiny specks in the night sky — but it paid off ｣

Astrum: Everything We Know About 3I/ATLAS, the New ‘Oumuamua
"A new visitor from beyond our solar system is hurtling towards us. Larger and older than ‘Oumuamua, it's unlike anything we've seen before. This massive, fast-moving comet, named 3I/ATLAS, is the third interstellar object ever detected and promises to reveal new secrets about the cosmos. In this video, we explore what makes this celestial traveler so unique and what mysteries it might unlock as it makes its close approach to the Sun."
Fascinating: ESA is now preparing the Comet Interceptor mission
The spacecraft will be launched in 2029 into a parking orbit, lying in wait for a suitable target – a pristine comet from the Oort Cloud, or, unlikely but highly appealing, an interstellar object.
