Yet when night overtakes a continent or ocean, scientists and forecasters suddenly lose important satellite imagery in the visible-light range-information that can reveal swirling storms, the choking smoke of wildfires, massive chunks of sea ice that threaten ships, and much more.Ī new sensor called the Day Night Band is beginning to fill that void.

Masi collected this imagery of Webb using a single 120-second exposure with the PlaneWave 17"+Paramount ME+SEBIG STL-6303E robotic telescope, nicknamed "Elena," that is available at the Virtual Telescope Project in Ceccano, Italy.Īt the same time that Masi was collecting these observations, Webb extended its deployable tower assembly (DTA), a step that gave the telescope the space to begin deploying its massive sunshield, according to the Virtual Telescope Project (opens in new tab).
To snap the "movie" of Webb, the robotic telescope tracked Webb's motion across the sky.
