NASA confirms that the first star Webb will see is HD 84406, a Sun-like star about 260 light years away. While it will be too bright for Webb to study once the telescope is in focus, it’s a perfect target for Webb to gather engineering data & start mirror alignment.

James Webb Space Telescope has turned on it's high-gain antenna, which helps enable a much higher data rate than the radio band Webb had been using until now
