Quick Answer
The first clear images of protoplanetary disks around young stars emerged in the 1990s.
The Full Story
By the 1990s, improved telescopes and imaging techniques allowed astronomers to directly image disks of gas and dust around young stars. These protoplanetary disks were important because they showed the raw material from which planets form. Observations from the Hubble Space Telescope and ground-based telescopes revealed dark silhouettes and glowing nebulae around newborn stars. The images helped confirm the basic model of planetary system formation.
