Black holes aren't stationary in space; in fact, they can be quite active in their movements. But because they are completely dark and can't be observed directly, they're not easy to study. Scientists have finally figured out the precise timing of a complicated dance between two enormous black holes, revealing hidden details about the physical characteristics of these mysterious cosmic objects.

California Nebula Stars in Final Mosaic by NASA's Spitzer
Five days before NASA's Spitzer Space Telescope ended its mission on Jan. 30, 2020, scientists used the spacecraft's infrared camera to take multiple images of a region known as the California Nebula — a fitting target considering the mission's management and science operations were both based in Southern California at NASA's Jet Propulsion Laboratory and Caltech.

In a First, NASA Measures Wind Speed on a Brown Dwarf
For the first time, scientists have directly measured wind speed on a brown dwarf, an object larger than Jupiter (the largest planet in our solar system) but not quite massive enough to become a star. To achieve the finding, they used a new method that could also be applied to learn about the atmospheres of gas-dominated planets outside our solar system.
