the sky's bruise, painted by solar wind crashing into atoms 60 miles up
means A natural light display in the sky, usually near the poles, where charged particles from the sun collide with atmospheric gases to produce shimmering colors.
from From the Latin aurora, meaning 'dawn,' and the name of the Roman goddess of the morning who reddened the eastern sky each day. It likely traces back to an even older Indo-European root for 'to shine' or 'glow,' a cousin of words like the Greek eos (dawn). The polar light shows earned the names aurora borealis ('northern dawn') and aurora australis ('southern dawn'), a poetic coinage often credited to early scientists who saw in those colored glows something of the morning's first blush.
