Interstellar comet 3I/ATLAS was born with different and more ancient chemistry, has been more irradiated, and is speeding toward the Sun faster compared to Solar System comets. It's got a unique personality. But since literally Day 1 it was recognized as a comet and has only ever done comety things.
I've summarized the truth about Loeb's 10 "anomalies" about 3I/ATLAS in one post.
Thanks to @deschscoveries.bsky.social @michael-w-busch.bsky.social @cometary.org and @marshall-eubanks.bsky.social for contributing their expertise!

Loeb’s 3I/ATLAS “Anomalies” Explained
Avi Loeb continues to claim that 3I/ATLAS has many anomalous behaviors that lead to the conclusion that it “might” be an alien spacecraft. He carefully hedges the probability that it is a spacecraft ...

The “canonical” story how Rosalind Franklin got wronged by Watson and Crick inadvertently makes her look far less scientifically competent than she was (“She did not realize the significance of her own data!”). This article offers a much more nuanced account of what happened.
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

3I/ATLAS has both Ni and Fe vapor, like 2I/Borisov and dozens of solar system comets. These are probably from carbonyls formed when metal reacts with ice, and seems pretty universal. Its 3I/ATLAS’s hyperbolic orbit that tells us it formed in another star system.
3I/ATLAS, a rare interstellar comet spotted in 2025, shows vaporised nickel far from the Sun metal usually won’t evaporate there. It hints at the comet formed in a distant, cold star system, possibly older than our Sun.

For the record, my answers are:
Probably, in some form, somewhere in the cosmos, since it’d be weird if Earth were THAT special. They probably haven’t visited though.
Yes, we can see it pretty directly! (More on this in next.)
There are surely some limits to our knowledge but we do know a lot.

We are pleased to announce our discovery of #GW241011 and #GW241110
Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger?

Why do corals glow in red, blue, electric green?
What pigments and microalgae weave this luminous symphony?
Could fluorescence be a trick for photosynthesis… or a warning cry to predators?

Fascinating detections from LIGO-Virgo-KAGRA!
#GW241011 & #GW241110 showcase unequal-mass, rapidly spinning black hole mergers—potentially hierarchical, with the massive primaries possibly "second-generation" relics from prior fusions in dense clusters.

We are pleased to announce our discovery of #GW241011 and #GW241110
Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger?
