The “ Wow! signal” was a short-lived narrowband radio signal picked up during a search for extraterrestrial intelligence, or Seti, by the Big Ear Radio Observatory in Ohio in 1977. “It is the first serious candidate since the ‘Wow! signal’,” they said. The beam that appears to have come from the direction of Proxima Centauri, a red dwarf star 4.2 light years from Earth, has not been spotted since the initial observation, according to an individual in the astronomy community who requested anonymity because the work is ongoing.
Scientists are now preparing a paper on the beam, named BLC1, for Breakthrough Listen, the project to search for evidence of life in space, the Guardian understands. The latest “signal” is likely to have a mundane explanation too, but the direction of the narrow beam, around 980MHz, and an apparent shift in its frequency said to be consistent with the movement of a planet have added to the tantalising nature of the finding. Until now, it’s only been possible to capture this particular signal from a galaxy nearby, limiting our knowledge to those galaxies closer to Earth,” Chakraborty said.It is usual for astronomers on the $100m (£70m) Breakthrough Listen project to spot strange blasts of radio waves with the Parkes telescope or the Green Bank Observatory in West Virginia, but all so far have been attributed to human-made interference or natural sources. “A galaxy emits different kinds of radio signals. But until recently, 21-cm-wavelength radio waves had only been recorded from galaxies nearby. Galaxies reportedly emit light across a wide range of radio wavelengths.

A radio signal 9 billion light years away from earth was detected by the Giant Metrewave Radio Telescope in India. “It’s the equivalent to a look-back in time of 8.8 billion years,” author and McGill University Department of Physics post-doctoral cosmologist Arnab Chakraborty said in a statement this week. Researchers detected the signal from a “star-forming galaxy” titled SDSSJ0826+5630, which was emitted when the 13.8 billion-year-old Milky Way – the galaxy where Earth resides – was just 4.9 billion years old. The signal captured by the Giant Metrewave Radio Telescope in India could mean that scientists can start investigating the formation of some of the earliest stars and galaxies, the report said. The signal was detected by a unique wavelength known as a “21-centimeter line” or the “hydrogen line,” which is reportedly emitted by neutral hydrogen atoms.
