NGC 7635: Bubble in a Cosmic Sea

Explanation: Do you see the bubble in the center? Seemingly adrift in a cosmic sea of
stars and glowing gas, the delicate, floating apparition in this widefield view is cataloged as NGC 7635 - The
Bubble Nebula. A mere 10
light-years wide, the tiny
Bubble Nebula and the larger complex of interstellar
gas and dust clouds are found about 11,000
light-years distant, straddling the boundary between the parental constellations
Cepheus and
Cassiopeia. Also included in the
breathtaking vista is open
star cluster M52 (upper left), some 5,000 light-years away. The featured image spans about two
degrees on the sky corresponding to a width of about 375 light-years at the estimated distance of the
Bubble Nebula.
