Question:
What is keeping us from discovering other solar systems?

Replies:
Their immense distance from us means that their size (as seen from Earth) is very small. The light from the star is much brighter than any light reflected from any planets the star might have, so we can't see the planets directly. We are seeking indirect evidence for other planetary systems by looking for small variations in the position of the central star caused by the gravity of possible planets.
