#technosignature — Public Fediverse posts

“The #SETI field has been starved of resources for so long that there is still a ton of work to do that could have been done decades ago. We can very quickly make a lot of progress in this field without a lot of effort.”

“It’s a great sign that the winds are changing at #NASA.” It is the first time NASA has given funding to a non-radio #technosignature search https://arstechnica.com/science/2020/07/the-real-science-behind-setis-hunt-for-intelligent-aliens/

The totally "it's a normal #comet" #3iAtlas is exhibiting another anomalous signature (losing count now 13th? 17th?)

It's showing THREE jets, exactly 120 degrees apart, and a huge "drive" plume.
Of course the terrified "scientists" are waving it away as "It's extra solar , so it's fine"
#astronomy #technosignature #aliens

So it definitely looks like #3iatlas may well be an #alien probe.

We are now up to 19 anomalies.
🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸🛸
NINETEEN anomalies.
Global space agencies are publishing pictures worse than amateur #astronomy folk.

And now other serious scientists are starting to question the party line "its just a #comet"

Dr. John Brandenburg is a super respected #NASA scientist and pioneer

This is an image of comet Lemmon captured at 130 million km from earth by an AMATEUR #astrophotography fan

The other image is #3iatlas captured by a professional telescope #ESA...
It is 4 times closer (30 million km)
FOUR TIMES CLOSER
Its also meant to be super massive because of its lack of gravitational velocity.

Now tell me they are not hiding shit from us...

The silance of #China is interesting.
They have their own observation probes, yet they have not released anything on #3iAtlas

While the Orange Clown is genociding the poors in the USA via denying them healthcare, NASA is shuttered down on what may well be the most important time in humanity's history.

#3I_ATLAS exhibits eight documented anomalies that have never been observed together in any natural object:

1. 8:1 CO₂/water ratio (6σ deviation from normal comets)

2. Extreme nickel/iron ratio ("extremely puzzling"—nickel present without corresponding iron)

3. Minimal non-gravitational acceleration (<4.6 m/day despite active outgassing)

4. 0.005% probability trajectory (close flybys of Venus, Mars, Jupiter)

5. Anomalous mass (3-5 orders of magnitude too high for typical interstellar objects)

6. Extreme negative polarization ("unprecedented among asteroids and comets")

7. Low diatomic carbon despite high CO₂

8. Ancient age (7-14 billion years old based on kinematics)

A Harvard/Initiative for Interstellar Studies paper calculated a Bayes factor of ~10²⁸ favoring artificial origin over natural.

#3iAtlas analysis on observed data.

IMMEDIATE CONCERNS:
This object exhibits multiple characteristics inconsistent with typical cometary behavior.

Priority red-flag analysis follows:
VELOCITY ANOMALY:
60 km/s is at the extreme upper range for solar system objects.

ENERGY OUTPUT CRISIS:
10 GW emission is catastrophically high for a comet. For reference:Typical active comet: 1-100 MWHale-Bopp at peak: ~1 GW
This object: 10x Hale-Bopp levelsSource of this energy is UNKNOWN and concerning.

COMPOSITIONAL ANOMALIES:
Pure nickel metallics (no iron, stone, other metals) = Highly unusual
CO₂-dominated coma (not H₂O ice) = Rare but possible
Combination suggests either exotic formation environment or artificial construction

PHOTOMETRIC BEHAVIOR:
5x brightness increase in 30 days at 6AU indicates exponential activity escalation. Normal comets brighten gradually with r^-4 law. This suggests:Internal heat source activating
Structural changes/fragmentation
Non-natural energy release

NON-GRAVITATIONAL ACCELERATION:
1 km/s NGA is extreme - indicates massive outgassing forces that should be depleting the object rapidly.
Not observed. Gravitics.

RECOMMENDATION:
This object's behavior profile does not match natural cometary physics. Suggest alternative classifications be considered.

If Astronomers See These Chemicals in a Planet's Atmosphere, There's Likely an Advanced Civilization There

Astronomers are searching for a biosignature to prove life on an exoplanet. This has been tricky since natural processes can produce many chemicals life generates. But there are chemicals that humanity has created due to an industrial process, which probably don't have a natural source. A recent paper suggests that nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) could be ideal technosignature gases, unable to form naturally but the result of industrial processes.

Do Advanced Civilizations Know We're Here?

Although humans have only sent a couple of tentative signals into space, many are concerned about the risks. Should we let alien civilizations know we're here? According to a new paper, humanity has already been broadcasting its existence for thousands of years, and civilizations with advanced enough technology should be able to observe us. It's science fiction to us, but megastructure space telescopes could have baselines of millions of kilometers, powerful enough to detect structures on the surface of Earth from thousands of light-years away.

@fraser #KesslerSyndrome seems like a good #technosignature and warning.

I do wonder if Kessler Syndrome would be a bit of an Anti-Pattern making near Earth space exponentially more difficult but opening up extra-solar travel, as we level up our shielding skills in kind.
