Galaxy SPT0418-47
Astronomers using ALMA, in which the ESO is a partner, have revealed an extremely distant galaxy that looks surprisingly like our Milky Way. The galaxy, SPT0418-47, is gravitationally lensed by a nearby galaxy, appearing in the sky as a near-perfect ring of light.

Giant Star Makes Waves !
This Spitzer image shows the giant star Zeta Ophiuchi and the bow shock, or shock wave, in front of it. Visible only in infrared light, the bow shock is created by winds that flow from the star, making ripples in the surrounding dust.
Located roughly 370 light-years from Earth, Zeta Ophiuchi dwarfs our Sun: It is about six times hotter, eight times wider, 20 times more massive and about 80,000 times as bright.
Even at its great distance, it would be one of the brightest stars in the sky were it not largely obscured by dust clouds.

A Space Spider Watches Over Young Stars !
Located about 10,000 light-years from Earth in the constellation Auriga, the Spider nebula resides in the outer part of the Milky Way. Combining data from Spitzer and the Two Micron All Sky Survey (2MASS), the image shows green clouds of dust illuminated by star formation in the region.
Right of center, against the black background of space, lies a bright group of stars called Stock 8. The radiation from this cluster carves out a bowl in the nearby dust clouds. Running in a tributary to the left of Stock 8 are more young stars that appear as red point sources.

Tarantula Nebula,
This image from NASA's Spitzer Space Telescope shows the Tarantula Nebula in two wavelengths of infrared light.
The red regions indicate the presence of particularly hot gas, while the blue regions are interstellar dust that is similar in composition to ash from coal or wood-burning fires on Earth.
