I've been an amateur astronomy for 60 of my 72 years. I remember text books saying we would NEVER be able to resolve stars as a disc, much less to resolve surface features.

@caseygtr Ай бұрын

Yeah, it's crazy to think the technological leaps we have made. People back then could never imagine things like using multiple telescope as an array with digital compiling to make a large virtual telescope or even being able to detect gravitational waves from colliding blackholes.

Looks like a Moiré pattern to me. You line up a bunch of offset images of the same static and it'll look like this, adjust the images slightly and observe zoom, scale and many distortion effects. I mean, has anyone mentioned why we are seeing nothing like the convection cells that occur on the sun..? Maybe people need to look at Moiré Patterns more..

I like to read old space textbooks. One said something about how to even see a Jupiter sized planet around a nearby star you’d need a stupidly large telescope. And even though it took us more than a century, that’s exactly what we did. We built several stupidly large telescopes, even put one in space.

I would venture to guess there is a very specific stellar mass that makes spots in a radial symmetry due to the stability of the field lines, much like the Earth's poles. Of course, the chaotic nature of fusion may make that difficult, but perhaps if it is spinning fast enough the fields might start forming toroidal rings like we have in the core of the Earth.

@@HanSolo__if you're referring to a ship which requires thousands of generations then sure. I don't think we'd ever go that route. Such a large scale. The more logical route would be sending multiple surveillance crafts, and then an incubation habitation craft. I haven't researched current proposals, but what I think would work is multiple of these incubation habitation crafts which are maintained by robots. Once the craft gets near the system it begins to incubate babies. Once the babies are developed, they are taught and grown up by the robots, taught by them, raised by them. I think that's fundamentally safer than relying on wasted generations of lives to reach a star system. The problem that arises is gravity for the development, it could be resolved I believe by an interia spinner that simulated 1g gravity once the child is old enough it could leave the simulated 1g sector and exercise to maintain bone density and health.

@stargazer5784 Ай бұрын

Our Sun should be well in to the red giant phase in about 4 or 5 billion years. As a rule of thumb, the smaller in mass a star is, the more slowly it evolves. We would have to know the initial mass of R Doradus to be able to make an educated guess as to it's age. Being about 70 percent of the Sun's mass now, after having ejecting some of it's outer layers, might suggest that it was originally about the same mass as Sol, so it might be several billion years older. 🤷‍♂️
