New Analysis of 1977 Wow! Signal Reveals Stronger Cosmic Mystery
The famous 1977 “Wow!” signal — a mysterious radio burst detected by Ohio’s Big Ear telescope — has been reanalyzed using modern computing techniques. Researchers digitized old telescope records, finding the signal was about four times stronger than first thought, peaking at 250 Janskys. The recalculations also refined its frequency and s...

Einstein Probe Detects Mysterious X-ray Flare with Record-Long Emission
An international team of astronomers has detected a peculiar fast-evolving X-ray transient, EP241021a, using China’s Einstein Probe. Unveiled in a May 12 arXiv paper, this transient stood out due to its long-lasting emissions lasting over 79 days—unprecedented among FEXTs. EP241021a also produced optical and radio emissions, suggesting a multi-...
