Happy belated Valentines Day

The Rosette Nebula (aka NGC 2237) is a cosmic cloud about 50 light years in diameter. Its long stem is composed of hydrogen gas. Its petals are "stellar nurseries" whose lovely, contours are sculpted by winds and radiation emitted by a central cluster of hot young stars.
