EUROPE: Using gravitational lensing, scientists found a nursery of stars located more than 11.6 billion light years from Earth. The technique combined a “much closer” galaxy as the natural telescope, and ALMA, or the Atacama Large Millimeter/submillimeter Array.
Gravitational lensing has long been helping astronomers see and examine far objects that available telescopes and instruments cannot “reach” or interpret.
Back in March of this year, astronomers published multiple images of a far-away supernova with the help of a gravitational lens provided by “nearby” galaxy cluster. In a study published in Science, a group of researchers revealed that that the cosmic phenomenon showed a supernova explosion four times in a cross-like pattern which is known today as the Einstein cross.
It’s like time traveling, four times, and may be comparable to taking shortcuts while engineers and scientists are still looking for new ways to improve our telescopes.
