"A telescope in space has sent back a cosmic Valentine picture - a stellar nursery resembling a pink rosebud. The Spitzer Space Telescope, launched last year, looked at a group of newborn stars embedded in a cloud of gas and dust called a reflection nebula. Located some 3,330 light-years away in the constellation Cepheus and spanning 10 light-years across, the rosebud-shaped nebula is home to about 130 young stars. Previous images of the gas cloud, known as NGC 7129, taken in optical light show a dusting of hot young stars against the luminescent cloud." Credit: NASA
