A bumblebee hums around the part of the night-time sky dominated by the constellation Scutum in this infrared image from NASA’s Spitzer Space Telescope.

The Milky Way Galaxy is full of wonders and not all of them can be seen easily with our naked eye. The stars and shapes in this image cannot be seen without the help of special telescopes and sensors aboard the orbiting Spitzer Space Telescope. Spitzer helps astronomers see warm objects, such as new stars, lurking in cold dust clouds. These objects are hidden from view by a thick veil of dust. The orbiting telescope sees the Universe in the infrared part of the electromagnetic spectrum that lies just below the range of visible light, like a rainbow. We don’t see infrared light but we can feel it as heat.
New stars forming deep in these clouds blew bubbles into the gas and dust. As they become hotter, the surrounding nebula will expand and begin to glow as ultraviolet light floods the area. Someday our naked eyes will behold new and spectacular nebulae.
