World’s Biggest Alien Search Enters Final Stage With 100 Mystery Signals
SETI scientists are using China’s FAST radio telescope to examine the final 100 unexplained signals from the historic SETI@home project. While experts expect most to be radio interference, the search marks the culmination of a massive global citizen science effort and sets new standards for future hunts for extraterrestrial intelligence.

NASA's James Webb Space Telescope Might Have Spotted Hidden Supermassive Black Holes
Mysterious “little red dots” spotted by the James Webb Space Telescope may not be tiny galaxies after all. A new study suggests they are supermassive black holes wrapped in dense gas and dust, perfectly disguised in the early universe and shining intensely in infrared light.

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...

Dead NASA Satellite Relay 2 May Have Caused Mysterious 2024 Radio Burst
In June 2024, a mysterious 30-nanosecond radio burst baffled scientists — until they traced it back to a surprising source: Relay 2, a NASA satellite offline since 1967. Researchers believe the signal could have been triggered either by a micrometeorite impact or an electrostatic discharge. The discovery, detailed in a new preprint study, highlig...

Mysterious "Dead" Satellite Sends Powerful Signal to Earth After Decades
The radio pulse was blasted from a defunct satellite, Relay 2, which was an experimental communications satellite launched in 1964.

Scientists Baffled By Mysterious Radio Waves Coming From Under Antarctica Ice
The researchers analysed signals travelling to the surface from below the ice, using a variety of instruments.

NASA Launching Rockets To Probe 'Mysterious' Clouds In Ionosphere
Scientists are hoping to understand the Sporadic-E layers that form in the lower portions of ionosphere, causing radio signals to reflect to Earth.

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-...
