Detonation of all those atomic and nuclear weapons decades ago are now bearing wormy fruit.

Question for Gortex.

Which star is 80 light years distant and considered a candidate to have planets that could support life ?

80 years since Trinity Test.

Ω

I'm assuming you know of this, I was not, at least not off the top of my mind so did a quick search and found...

The star HD 156668, located approximately 80 light-years away, is noted for hosting a "super-Earth" exoplanet, HD 156668b, with a mass about four times that of Earth. This planet was detected in 2010 and is described as orbiting much closer to its star than Earth does to the Sun, resulting in high temperatures (1,200–1,648°C). Due to these extreme conditions, it is unlikely to support life as we know it, despite its "super-Earth" classification.

For stars slightly closer or farther, more promising candidates: Gliese 12, about 40 light-years away, hosts Gliese 12 b, an Earth-sized exoplanet in the habitable zone of its red dwarf star, with a surface temperature around 42°C, making it a strong candidate for potential habitability.

L 98-59, 35 light-years away, has a super-Earth, L 98-59 f, in its habitable zone, receiving similar stellar energy to Earth, suggesting conditions where liquid water could exist.

Course that doesn't mean there is not one similar to Earth 80 light years distant; just we haven't yet detected one.

Well......( spread hands )  what the hell is it?

Kenzo, I propose a perfectly human response.  Let's fire a missile tipped with a thermonuclear warhead at it.

Data from another in the line of telescopes looking at 3I/Atlas has been released and in line with the others the Very Large Telescope based in the Atacama Desert has found its own anomalies.

A new paper on spectroscopic data from the Very Large Telescope (accessible here) reported the surprising detection of nickel without iron in the plume of gas around 3I/ATLAS. Nickel without iron is a signature of industrial production of nickel alloys. This data constitutes a new anomaly of 3I/ATLAS. Natural comets generically show iron and nickel simultaneously, as both elements are produced together in the ejecta of supernova explosions.

Is this anomaly another clue for a possible technological origin of 3I/ATLAS? The paper suggests chemical formation through the nickel carbonyl channel which is an extremely rare and exotic possibility in comets, whereas it is a standard technology for industrial nickel refining.
The inferred mass loss rate of nickel for 3I/ATLAS is about 5 grams per second at a heliocentric distance of 2.8 times the Earth-Sun separation (AU). It exhibits a dramatic rise with decreasing distance from the sun, with a power-law index of -8.43 (+/-0.79).

The spectroscopic data on the plume surrounding 3I/ATLAS also reveals cyanide (CN), with a mass loss rate of about 20 grams per second at 2.85 AU and an even steeper dependence on heliocentric distance to the power of -9.38 (+/-1.2).

The luminosity of the object is still causing problems , is its brightness due it being even bigger than we thought or could it be producing its own light ? , questions I'm sure will be answered before perihelium ... or perhaps shortly after when it changes course and takes up orbit.

Maybe an alien mining/refining platform?

Slipped its leash perhaps and gone a roaming ?

Yeeh, and that could have happen eons ago....time before our solar system even was here.

As long as it's not that robotic Planet killer thing from Star Trek I think we're good.
