Newborn stars peek out from beneath their blanket of dust in this image of the Rho Ophiuchi nebula. Young Stars in Their Baby Blanket of Dust This image from Spitzer zooms in on a few members of the sisterhood. The filaments surrounding the stars are dust, and the three colors represent different wavelengths of infrared light. The Pleiades star cluster, also known as the Seven Sisters, is a frequent target for night sky observers. Visible only in infrared light, the bow shock is created by winds that flow from the star, making ripples in the surrounding dust. This Spitzer image shows the giant star Zeta Ophiuchi and the bow shock, or shock wave, in front of it. In honor of Spitzer’s Sweet 16 in space, here are 16 amazing images from the mission. Spitzer has additionally investigated some of the universe’s oldest galaxies and stared at the black hole at the center of the Milky Way. It has illuminated hidden collections of dust in a wide variety of locations, including cosmic nebulas (clouds of gas and dust in space), where young stars form, and swirling galaxies. The telescope has also provided weather maps of hot, gaseous exoplanets and revealed a hidden ring around Saturn. Thanks to Spitzer, scientists were able to confirm the presence of seven rocky, Earth-size planets in the TRAPPIST-1 system. Since then, the observatory has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light. We launched our Spitzer Space Telescope into orbit around the Sunday on Aug.
