Starship Asterisk*

Thanks for the reply from "honest Rob". I think what you are saying is that no good theory is available just yet. May I explore the depths of your mind on this subject ? I believe electrons rotate magnetic field lines of force in a certain direction according to Lenz Law. These electrons n...

I noticed recently a discrepancy in Wikipedia concerning the distribution of postulated Oort Cloud objects. The first illustration shows a homeogeneous spherical distribution beyond the Kuiper belt with a disk concentration called the Hill Cloud. A second illustration indicates a spherical shell wi...

I am still wondering where all the "killer electrons" from the solar eruptions and winds go when they are captured by the magnetic field lines of the Earth's dipole field ? I do not believe they find the Earth's surface in a random fashion and overload man's electronic equipment. Still ele...

Real thinking does take time. Keep doing it.

http://asterisk.apod.com/viewtopic.php?p=184575#p184575 I have reviewed the referenced articles that have tried to explain these strange grooves. One article explains that a large collision could have created the asteroid's troughs. The article further explains: "The crustal layer at the surfa...

Or perhaps these equatorial grooves were created by a very slow collision between two bodies. Their surfaces crumpled where they came together and eventually filled in with regolith materials to create the rounded grooves.

Have NASA scientists developed an postulations yet?

Doug

Dear Bystander, Thank you for providing these excellent papers on the subject. I believe you have given me my answer. The paradigm shift is due to attempts for arriving at better collision scenarios to create the Earth-Moon system and address the isotopic anomalies discovered during our Moon explora...

Mankind colonized all the land masses on Earth. Now you say its time to colonize the solar system except its other bodies are not hospital - not at all. Now you say its time to colonize other star systems. If there is a star system that has a habitable planet, then I am sure it is already inhabited....

I guess collisions have already become a boring subject. Is there any estimation of the minimum ratio of two large masses colliding with each other with a moderate planetary velocity differential and not self-destructing ?

Trying to deploy the forum,

Hello to all interstellar explorers, I guess I stopped the "worldship" dead in its tracks. Yes, indeed we have found the "worldship" and it is Earth. The "worldship" is already designed and traveling through intersteller space (orbiting the galaxy every 250 million year...

Hello Owlice, Thank you for finding a tailor-made answer for my question. I wonder if Copernicus actually collected all the data for conjunctions, elongations, oppositions, and quadratures, especially for Saturn. Perhaps he used data handed down from past generations. He also had to be a student of ...

How do scientists know the ages of the two largest craters on Vesta at one and two billions year ago?

Doug

Thanks for the reply,

Copernicus preceded Brahe and Kepler. How did he surmise the order of the planets from the Sun?

Doug

I going to try and dredge-up a reply from Neufer with his treasure trove of trivia. I am guessing each planet is tracked across the sky and the number of days is tabulated for its return at the same longitude for the planets outside Earth's orbit. The longer the period the farther the planet is from...

Let me guess what you are thinking. The ejecta is expelled rather slowly and steadily. The heliomagnetosphere of the smaller star attracts and/or drags the expelled material causing it to spiral. As this ejecta passes the companion star in its outward migration it maintains a spiralling trajectory. ...

Computers and medical doctors are like the "smaller gods". They can be very helpful with answers, but in many cases the smaller gods are not given all the input or the correct input. Hence, the smaller gods who are dependent on the inputters may easily be wrong. In other words, be careful ...

I see no evidence of a binary companion. And I see no reason how such an object can cause a spiral of such dimensions. The outer ring is actually a dis-connected circle; the inner regions show more spiral characteristics. The configuration of the nebula is indicative of how the star is ejecting mate...

Chris, thank you for your patience and your answers. I promise that I have only only more question about asteroids. There are supposely computer simulations of accretion models for the inner planets and embryos for the Jupiter and Saturn. Supposely, these models have some agreement with the lifetime...

The subject grooves appear to be fairly new with little disturbance of meteor strikes. The grooves then may have occurred close to the time of the major recent impacts at the south pole of 1 and 2 bya. A possible idea is that the energy of impact created a very molten, but intact interior core. The ...

How are the ages of the two largest crater systems, one billion and two billion years, determined ?

Doug

I personally do not have any hypothesis for Apollo asteroids unless they were left over from some giant impact of a minor planet with early Earth. So scientists believe that all collisional debris created by the event of the Giant Impact Hypothesis that created the Moon has been completely swept cle...

A near miss of a plotted few hundred miles by a 10 km asteroid will cause a general ruckus; such as large populations traveling to mountains tops to pray or die; or NASA sending a diversionary apparatus to meet it in interplanetary space. Thanks for telling me about the barycenter calculation. I sti...

I believe I know the answer. Nobody knows where the rock came from. It is the kind of rock that on Earth is called an "erratic".
