Mysterious ‘Wow!’ signal from deep space was much stronger than first thought, scientists say
Experts make new discovery in study of most promising ‘alien’ space signal ever detected
- A new study suggests the mysterious "Wow!" signal from deep space, detected in 1977, was significantly stronger than previously thought.
- Volunteers processed over 75,000 pages of the signal's original data, enabling the first in-depth computer analysis of the radio waves.
- The analysis allowed researchers to narrow down the signal's sky location by two-thirds and correct its frequency calculation, indicating a rapidly spinning source.
- The findings definitively rule out human-made interference or internal software errors as the cause, confirming the signal's astronomical origin.
- While supporting an astrophysical origin, the study does not confirm an extraterrestrial source but provides the most precise constraints to date for further investigation.
