Astronomie - Hubble Detects Dynamic Galactic Duo

Some galaxies are closer friends than others. While many live their own separate, solitary lives, others stray a little too close to a near neighbor and take their friendship even deeper.

The two galaxies in this image taken by the NASA/ESA Hubble Space Telescope, named NGC 6285 (left) and NGC 6286 (right), have done just that! Together, the duo is named Arp 293 and they are interacting, their mutual gravitational attraction pulling wisps of gas and streams of dust from them, distorting their shapes, and gently smudging and blurring their appearances on the sky — to Earth-based observers, at least.

Hubble has viewed a number of interacting pairs. These can have distinctive, beautiful, and downright odd shapes, ranging from sheet music to a spaceship entering a sci-fi-esque wormhole, a bouquet of celestial blooms and a penguin fiercely guarding its precious egg.

Arp 293 is located in the constellation of Draco (the Dragon) and lies over 250 million light-years from Earth.
