Planet-forming Lifeline Discovered in a Binary Star System - ALMA Examines Ezekiel-like “Wheel in a Wheel” of Dust and Gas
For the first time, researchers have detected a streamer of gas flowing from a massive outer disc toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disc of planet-forming material that otherwise would have disappeared long ago. Half of Sun-like stars are born in binary systems, meaning that these findings will have major consequences for the hunt for exoplanets. (ESO)
Andromeda Galaxy ~ a massive spiral, 2.5 million light-years away, over twice the diameter of our own Milky Way, it's the largest nearby galaxy. Its population of bright young blue stars lies along its sweeping spiral arms. (Spitzer Space Telescope)

The universe is filled with galaxies. But to see them astronomers must look out beyond the stars of our own galaxy, the Milky Way. This colorful Hubble Space Telescopic portrait features spiral galaxy NGC 6384, about 80 million light-years away in the direction of the constellation Ophiuchus.
Spiral Galaxy Messier 81 The magnificent spiral arms of the nearby galaxy Messier 81 are highlighted in this NASA Spitzer Space Telescope image. Located in the northern constellation of Ursa Major (which also includes the Big Dipper), this galaxy is easily visible through binoculars or a small telescope. M81 is located at a distance of 12 million light-years.
