Here’s a timelapse of images over 2. 5 hr from May from @keckobservatory of the supermassive black hole Sgr A*. The black hole is always variable, but this was the brightest we’ve seen in the infrared so far. It was probably even brighter before we started observing that night! pic. twitter. com/MwXioZ7twV— Tuan Do (@quantumpenguin) 11 августа 2019 г.
