Reply to How long do you predict it will take before a probe reaches a habitable exoplanetand actually sends back footage of alien life? by sky_shrimp
Thousands of years.
There are multiple very high odds factors (low probability) in your question: Finding signs of life, knowing beforehand that the planet actually has "advanced" life, getting there (acceleration+deceleration) with our tech, known physics, fuel.
Thousands of years.

Imho, a permanent base on the Moon. MUCH more likely to happen than humans/permanent base on Mars.

Reply to Why from Earth do we see all these stars but in images taken from space we see none? by Suitable-Victory-105
Take a shoe outside during a sunny day and take a picture of it.
At night, take a picture of the Moon.
What do these images have in common? They are both of sunlight reflected once, which means they were taken using the same settings!
So anything sunlit in space is going to be so bright you will have to lower the exposure settings to not get an over-exposed image, which will also result in no stars, as they are so much weaker.
