Oumuamua (1I) and Vega


Last year saw the first out of Solar System object zoom by. Some said it was obviously an extraterrestrial starship considering its shape and speed and origin:

The subject of planets around other stars is as philosophical as philosophical can be: Giordano Bruno was tortured for 7 years, and burned alive, after mutilations, just for claiming there were other star systems, with planets… (that offended the Jesus myth… Did each inhabited planet come with its own little green Jesus?)

We need hope, a wider perspective: the cosmos provides them, even if we don’t get there, we can dream of it… Dreaming leads. Good dreams do best…. And displace nightmares… Loving the cosmos displaces hating neighbors
Planetary formation is a subject in formation… and crucial, for giving us humans cosmic hope and purpose, an arrow for civilization…. Seems to me Dr. Ian Miller is saying that HABITABILITY, usually interpreted as the zone in a Solar System where liquid water can be found on the surface, also influences planetary formation crucially. I like it, a lot.

My own original idea on life creating planets is that they need to be in the radioactive belt… Habitability is a different notion:

Oumuamua is a small asteroidal object somewhere between 100 – 1000 meters long and is considerably longer than it is broad. Basically, it looks like a slab of rock, and is currently passing through the solar system on its way to wherever. It is our first observation of an interstellar object hence the bracketed formal name: 1 for first, I for interstellar. How do we know it came from interstellar space? Its orbit has been mapped, and its eccentricity determined. The eccentricity of a circular orbit is zero; an eccentricity greater than zero but less than one means the object is in an elliptical orbit, and the larger the eccentricity, the bigger the difference between closest and furthest approach to the sun. Oumuamua was found to have an eccentricity of 1.1995, which means, being greater than 1, it is on a hyperbolic orbit. It started somewhere where the sun’s gravity…

    Re: life needing to be in a radiation zone (could be EM) see Nobel laureate Luc Montagnier’s incredible experiment on the spontaneous creation of DNA under EM radiation. The general view represented here is that manifest reality is ordered by extra-reality “guide field.” Also, some believe human consciousness affects earth events, weather, etc. The Russians are into this stuff, starting with Kosyrev.

      Kozyrev:…. “Started by the accusations of a disgruntled graduate student, most of the observatory staff died as a result. Kozyrev was arrested in November 1936 and sentenced to 10 years for counterrevolutionary activity. In January 1941, he was given another 10-year sentence for “hostile propaganda”. While incarcerated, he was allowed to work in engineering-type jobs. Due to the lobbying by his colleagues, he won an early release from detention in December 1946.[1] As a result of his imprisonment he was mentioned in The Gulag Archipelago by Alexandr Solzhenitsyn.[2]

      During his imprisonment, Kozyrev attempted to continue working on purely theoretical physics. He considered the problem of the energy source of stars and formulated a theory. But in his isolation, he was unaware of the discovery of atomic energy. After his release, Kozyrev refused to believe the theory that stars are powered by atomic fusion.”

      So well…. One can fall off science… But I agree with you radiation is important… Red Dwarves have plenty of that, BTW… And I said more:

    Not quite, Patrice. What I am saying is there are three temperature profiles at different times that are important. During stellar accretion, there is an important temperature around 1550 degrees C, where iron melts and certain aluminosilicates phase separate. This cools, and in the immediate aftermath of stellar accretion the rocky planets form. The critical temperature now is about current temperature, where the aluminosilicates can absorb water. (Venus failed here because ti was too hot, and never absorbed much water.) The third temperature is the habitability zone, which seems to be roughly the same as the second zone. Fort a successful planet to have life, all three have to be at about the same distance from the star. It seems as if number 2 & 3 are likely to coincide, but not with 1 except for G and heavy K stars. Red Dwarfs should have the first stage too close to the star, most of the time, but there are some further variables, such as the amount of dust and how fast the star accretes, so a general rule is difficult. The bad news is that once the system is formed, knowledge of the early stages is removed.
