These disks last just a few million years—no time at all, to the 13.7 billion-year-old universe, but impossibly long to humanity. But just a decade ago, we would have missed most of them. At that time, says astronomer Henning Avenhaus, "any of these individual eight disks would have warranted a paper." At the ESO, it's possible to see lots of them—if you can snag time with the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, AKA SPHERE. This cutting-edge instrument, which is able to take direct images of the exoplanets surrounding close-by stars other than our Sun, is only available to researchers at two times per year. It's primarily used for looking at existing exoplanets, not for looking at dusty disks, which are still a little-understood phenomena. SPHERE is capable of cutting down the light from stars so the exoplanets—and the dusty disks—surrounding them can be seen using polarized filters and adaptive imaging technology. It's part of the ESO's Very Large Telescope. It was installed in 2014, but only imaged its first confirmed planet in 2017. When Avenhaus visited, he says, "I went to the telescope and was expecting to see three disks at most." His team was able to observe eight in total, surrounding T Tauri stars, the youngest visible type of star at less than 10 million years old. These T Tauri stars are between 230 and 500 million light-years away from Earth.
