Answer to Question 1

COBE is the Cosmic Observer of the Background Energy, and focused on the structure of the microwave cosmic background; its discovery of ripples in 1992 showed how the seeds of galaxies were sown in the early universe. The WMAP spacecraft made much more detailed measurements of the cosmic microwave background, confirming and extending COBE's results.

B
