But no brakes. How do you stop a solar powered sailcraft travelling at a significant fraction of the speed of light? Would you need an equal distance to stop as you need to accellerate?

What we need is the technology to warp. Travelling at light speed will still take 20 bloody years to get there.
If we could travel 3 times the speed of light we'd be there in 26 weeks.

Being an atheist says nothing about your overall intelligence, it just means you don't believe in god. Atheists can be as bright as any scientist and as stupid as any creationist.
You never really know just how stupid someone is, until you've argued with them.

No absolute eed to slow down. The probe can return large amounts of data just zipping by at near speed of light.

Why are you restricting it to bacteria?
If you'd read the original post one of the things seen was lasers eminating from that system. Highly advanced bacteria then.
There could be nothing or there could be something really cool.
What we need are better telescopes. 20 light years showed be no problem for a next gen space based telescope.

Mars sounds infinitely more doable for the foreseeable future.

BTW, I am not sure what is meant by "no problem"? Let's say the planet is 15,000 Kilometers in diameter and the largest features on it, say a giant impact crater, an ocean or a continent, is 7,000 Kilometers. Using small angle approximation, from 20 light years a theoretically perfect optical telescope will need an aperture of about 800 Kilometers to resolve it.
Hubble's aperture is about 5 meters.
Failing to resolve surface details, or having any intelligent alliens the most we can do it to try to detect through spectral analysis whether the atmosphere contains any gases which should not remain in the atmosphere for long without being continuously resupplied by biological or technological activity. The chance of finding a smoking gun with this technique that will definitely put aside any doubt seems small. Even having set foot on Mars and surveyed its atmopshere with multiple low orbit satellites we can't be sure if what is Martian atmosphere is indicative on ongoing biological processes or not.

Yep, hubble is completely insufficient for having a good look.
The James Webb telescope being launched in 2 years is much more powerful than hubble and should provide us with a much more significant analysis, especially spectral. The chances of finding liquid water in this region are still very good just considering physical law, the distribution of heavier elements from a supernova and the basic rules of chemistry. For there to be no water at all would mean that we have a lot of rethinking to do.
