I swear there used to be a 3d map that you could navigate, rotate zoom in zoom out of local space, but I can't find it anymore.

Does anyone else remember that or am I imagining it? I think it was like 10 years ago

are you thinking about 100,000 stars? https://stars.chromeexperiments.com

It should be a goal for Earth to send a probe to one of those stars. As the probe will be unmaned, a mission taking a hundred years or more is not out of question.

How would it be powered?

some combination of nuclear radiation and/or solar seems like it would fit the bill? 100 years is within the useful range of a large radioisotope generator.

RTGs lose power rapidly as the isotopes decay, and any sort of communication over those distances requires massive power. The Voyagers are essentially dead due to this issue, and they haven’t been out there nearly that long.

There are already plans to reach alpha centauri in about 20 years with unmanned probes (1). There still remain some technical hurdles in terms of the laser design to propel these probes afaik but it seems like this could be solved with more funding.

Too bad we are in the current era of eschewing scientific research in favor of crony politics.

One issue with the latter is that tech is likely to advance fast enough that a subsequent probe launched a couple of decades later would overtake the first probe.

Regarding the former, various studies have been made and will certainly continue to be made: https://en.wikipedia.org/wiki/Interstellar_travel#Designs_an...
