M33: A Close Neighbor Reveals its True Size and Splendor (3-color composite)
One of our closest galactic neighbors shows its awesome beauty in this new image from NASA's Spitzer Space Telescope. M33, also known as the Triangulum Galaxy, is a member of what's known as our Local Group of galaxies.
This image from NASA's Spitzer Space Telescope shows the nasty effects of living near a group of massive stars: radiation and winds from the massive stars (white spot in center) are blasting planet-making material away from stars like our sun.
This visible light/infrared image from NASA's Spitzer Space Telescope shows a swirling landscape of stars known as the North America nebula. Clusters of young stars (about one million years old) can be found throughout the image.
A dragon-shaped cloud of dust seems to fly out from a bright explosion in this infrared light image from NASA's Spitzer Space Telescope. These views have revealed that this dark cloud, called M17 SWex, is forming stars at a furious rate.
This infrared portrait of the Small Magellanic Cloud, taken by NASA's Spitzer Space Telescope, reveals the stars and dust in this galaxy as never seen before. This nearby satellite galaxy to our Milky Way galaxy is some 200,000 light-years away.
Generations of stars can be seen in this new infrared portrait from NASA's Spitzer Space Telescope. In this wispy star-forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities.
