'Cosmic rose' shines in Space on Valentine's Day
The region of Space known as 'W5' may not sound very romantic but as these pictures from NASA show, if you take a closer look, it looks like a giant floating rose, or even a heart.
Different generations of stars can be seen in this portrait taken by the Spitzer Space Telescope. The oldest stars can be seen as blue dots in the middle of two hollow cavities. Younger stars line the rims of the cavities, and some can be seen as pink dots. The red shows areas of heated dust.
