They were particularly looking at redshift, a phenomenon in which light waves stretch out or become redder as an object moves away from the observer. In this case, the redshift suggested HD1 was extremely distant. The researchers found that the red wavelengths were the equivalent to a galaxy located 13.5 billion light-years away. HD1 also seems to be growing at a feverish rate — about…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2201.00823/"&gt;Paper and discussion history&lt;/a&gt;.
