Foundations other work depends on. Each entry explains what it is, why it is load-bearing, its open problems, and a reviewed timeline of progress.

Numerical methods that evolve fluid flow together with the photons or neutrinos that heat, cool and push it; the hard part is transport at the speed of light across huge opacity ranges.
Combining signals from widely separated antennas samples the Fourier transform of the sky; imaging means inverting that incomplete, noisy data. It underlies radio surveys and black-hole images.
The two workhorse methods for finding planets: periodic dimming as a planet crosses its star, and periodic Doppler shifts as it tugs the star. Both are limited by stellar variability once planets get small.
