From the vibrant startup scene to cutting-edge research institutions, New Zealand's tech landscape is a dynamic force, driving the nation's technological

Astronomers have detected the most distant fast radio burst (FRB) ever recorded, an 8-billion-year-old pulse that has been traveling for more than half the lifetime of the universe. FRBs are intense, brief flashes of radiation that are invisible to the naked eye but can be detected by radio telescopes. They provide a new tool for studying the "cosmic web" of matter between galaxies.

Astronomers have made a groundbreaking discovery after detecting a fast radio burst (FRB) that occurred 8 billion years ago. This particular FRB, known as FRB 20220610A, released an amount of energy equivalent to the sun's emissions over three decades in less than a millisecond. The FRB was detected using the ASKAP array of radio telescopes in Australia and its source was found to be an older galaxy that is further away than any other known FRB source.

Astronomers have detected an intense flash of radio waves coming from what looks like a merger of galaxies dating to about 8 billion years ago - the oldest-known instance of a phenomenon called a fast radio burst that continues to defy explanation. This burst in less than a millisecond unleashed the amount of energy our sun emits in three decades, researchers said. It was detected using the Australian SKA Pathfinder, a radio telescope in the state of Western Australia.
