Amazing. The very fact that this is something we can share is humbling
7 years of work. This was done by ucla I’m p sure and the prof won a Nobel prize iirc
If I understand this gif correctly, we were able to do so because this system is perpendicular to ours.
If that is correct and I am interpreting this correctly I am confused though. The innermost planet would even do one revolution in all those years.
What is the black spot around the “star symbol”? Surely the whole black spot is not the star? Because that would make the star like 10-15 au? That seems extremely big…
Massive! Accomplishment and system… [https://www.aanda.org/articles/aa/full_html/2020/06/aa36783-19/T1.html](https://www.aanda.org/articles/aa/full_html/2020/06/aa36783-19/T1.html) that inner giant is 4-5x out further than Jupiter (and 10x massive!).
I could watch this for hours. That’s a fucking *solar system* on video
