OBJECTS IN THE NIGHT SKY

Summary from the TLDR newsletter

The BlueWalker 3 communications satellite can turn ordinary smartphones into satellite phones. It is the brightest satellite in low Earth orbit yet, and there are concerns that it may usher in a new generation of satellites that create way more light pollution than their predecessors. The satellite is bright due to its large size. It is about as bright as the eight-brightest star visible from Earth.
