Its story

57 Pegasi is an M-type red giant, an old and swollen star whose brightness drifts at the slow tempo of cool stellar atmospheres. It rides along the flank of Pegasus at some seven hundred and eighty-two light-years, in a stretch of the autumn sky where the unaided eye can only just catch it. Its reddish light has travelled for centuries, crossing nearly unfathomable voids, before halting tonight on a dilated pupil.
