And for all that was found, there are likely thousands of moons and Earth-sized worlds right in the the same field of view, just waiting for better techniques to find them!
It will be nothing short of a world-changing event when we start directly imaging them directly.
That’s the next story I plan to post... :’)
And I wholeheartedly agree — the first discoveries were bigger than Jupiter, then as more observers got involved with better and better technology and new ideas, the detection limit kept getting smaller, a process still going on today.
