ALMA sees Einstein ring in stunning image of lensed galaxy

Astronomers have discovered that a distant galaxy—seen from Earth with the aid of a gravitational lens—appears like a cosmic ring, thanks to the highest resolution images ever taken with the Atacama Large Millimeter/submillimeter ...

Dusty substructure in a galaxy far far away

Scientists at the Max Planck Institute for Astrophysics (MPA) have combined high-resolution images from the ALMA telescopes with a new scheme for undoing the distorting effects of a powerful gravitational lens in order to ...

Dwarf galaxy that reveals the history of the universe
