Eye on the Night Sky
Tuesday, March 17, 2026
Today:
The brightest star in the sky, Sirius, sparkles in the south as twilight fades by 8:00 PM, sliding into the southwest through the course of the evening, one of the first stars out as twilight fades. Its brilliance is due, in part to its relative closeness, only 8.6 light years away, as well as putting out about 25 times more light than our Sun.
