The Chile-based Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes employed a sort of cosmic magnifying glass to study a galaxy called H1429-0028, which lies about 6.9 billion light-years from Earth. This phenomenon, known as gravitational lensing, occurs when a huge object in space such as a galaxy bends light coming from other bodies behind it. "These chance alignments are quite rare and tend to be hard to identify," study lead author Hugo Messias, a researcher at both Conception University in Chile and the University of Lisbon in Portugal, said in a statement. "Recent studies have shown that by observing at far-infrared and millimeter wavelengths, we can find these cases much more efficiently."
