This image shows dust and molecules in the central region of our galaxy. The background image shows the dust emission in a combination of data obtained with the APEX telescope and the Planck space observatory at a wavelength around 860 micrometers. The organic molecule iso-propyl cyanide with a branched carbon backbone (i-C3H7CN, left) as well as its straight-chain isomer normal-propyl cyanide (n-C3H7CN, right) were both detected with the Atacama large millimeter/submillimeter array in the star-forming region Sgr B2, about 300 light years away from the Galactic center Sgr A*.
