Ladies and gentlemen, @deschscoveries.bsky.social and @astrowright.bsky.social called it months ago. In Avi Loebs latest he claims the line " I always said it was most likely natural , my stance hasn't changed". The man is a modern day grifter and a plague on science.

I helped Professor Dave lay out exactly how Avi Loeb has manufactured doubt and pushed a false narrative about 3I/ATLAS, which is still an interstellar comet. Please enjoy the video and please repost this to share the word.

It looks like our interstellar visitor 3I/ATLAS has finally gotten a dust tail. Very nice picture from

We now have astrometric data from on 3I/ATLAS from the Mars
Trace Gas Orbiter.

TGO is in the MPCD as V132!

Good work ESA! Hopefully soon we will see Psyche and MRO astrometry up there soon.

Since comet 3I/ATLAS, the third known interstellar object, was discovered on 1 July 2025, astronomers worldwide have worked to predict its trajectory. ESA has now improved the comet’s predicted locati...

You can look here at the orbit freely publicly available and updated as soon as new observations are reported. The Orbit Viewer is good to play with if you want to get a sense of motion through time

We are 100% right now.

No one who knows anything about comets is worried. You can relax!

On our interstellar visitor 3I/ATLAS: Its perihelion (closest approach to the Sun) is tomorrow at 11:32:07 UTC!

We have a new PUNCH magnitude estimate from astronomer Thomas Lehmann. If indeed the total brightness has gone up by a magnitude, that would be good for Juice.

BTW, we have enough lower resolution data around and after the Mars photo op to be sure 3I isn't up to that much. It's not changing its orbit much, for example.

Observing 3I/ATLAS from space is not like taking a picture of pretty cloud out of the window of a train or bus. This is more like designing multiple pop-up space missions on the fly in a very compressed time. A bunch of people have worked very hard for weeks to get the data we are getting.

Yes, we'll get good data from MRO and Juice, and are getting right now cruder updates from PUNCH, CCOR-1 and LASCO, to somewhat better than an arc minute (~90,000 km at 2 AU). While that's not that accurate compared to most astrometry, it does mean 3I is not zooming off in some random direction.

Two new analyses of PUNCH wide field imager data on our interstellar visitor 3I/ATLAS, both using more processed PUNCH data.

There is a general agreement on a spike around October 3rd - during the Mars spacecraft photography period!

However, the Oct 13 points do not agree well. Still more to do...

I found some time to work out some of the things that are wrong in Loeb's latest calculation.

When you are fitting data, you are not sensitive to all deviations from your model, only those that your model can't absorb!

Anyway, happy to receive corrections from Planetary Science Bluesky.

No, Loeb Has Not Shown the Size of 3I/ATLAS to be around 5 km
So, in a preprint and in many blog posts, Loeb is claiming that he and others have estimated the mass of 3I/ATLAS from the lack of any measured non-gravitational acceleration.  He keeps repeating that...

So are all the click-bait 3I/Atlas doom posters going to STFU now that precisely nothing wild and doomy has happened?

We were not in fact being invaded by a marauding armada, or given incredible alien insights to undeservedly help us.
