Chinese Astronomers Search for Extraterrestrial Signals in TRAPPIST-1 System
Chinese scientists turned the world’s most sensitive radio telescope, FAST, toward the TRAPPIST-1 system, a promising site for alien life with seven rocky planets. Although no signals were detected, the study set new limits on possible extraterrestrial transmissions and highlighted advanced techniques driving today’s search for intelligent life...

India’s PRATUSH Computer Could Detect Signals From the Universe’s First Stars: Report
RRI’s PRATUSH—a credit-card-sized computer payload—will detect faint radio signals from hydrogen to study the “Cosmic Dawn”. Designed for deployment on the Moon’s far side, the system offers noise-free, efficient data handling using an SBC and FPGA combo. If successful, it could help determine when the first stars formed and expand our ...

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...

Astronomers Detect RBFLOAT, Brightest Fast Radio Burst Ever Observed
An international team of astronomers has detected RBFLOAT, the brightest fast radio burst (FRB) ever recorded, just 130 million light-years away in Ursa Major. Detected by CHIME in March 2025, the powerful radio flash was traced to galaxy NGC-4141. Follow-up imaging with the James Webb Space Telescope revealed a faint stellar source near the burst,...

Sun Erupts with Triple Solar Flares After Weeks of Silence
After a 22-day period of solar calm, the Sun unleashed three M-class solar flares on August 3–4, 2025, all originating from active sunspot region AR 4168. These moderate flares released intense radiation, capable of briefly disrupting high-frequency radio signals and potentially sparking auroras at high latitudes. Scientists also detected likel...

Starlink’s Unintended Signals Threaten Astronomical Research, Study Finds
Astronomers have raised concerns over Starlink’s unintended radio emissions interfering with space observation. A Curtin University study found emissions from SpaceX satellites impacting up to 30% of astronomical data. Experts urge updated regulations to protect radio astronomy, as current rules overlook these non-deliberate signals from satellit...

Scientists Trace Universe’s Missing Ordinary Matter Using FRBs and X-rays
New astronomical breakthroughs have identified where the universe’s “missing” ordinary matter resides. Using 70 FRBs, including one from 9 billion light-years away, scientists discovered that 76% of ordinary matter exists between galaxies. A separate X-ray study observed an enormous hot gas filament connecting galaxy clusters.

Most Distant Mini-Halo Discovered in Galaxy Cluster 10 Billion Light-Years Away
Astronomers have uncovered the most distant mini-halo ever detected, located around the galaxy cluster SpARCS1049, a staggering 10 billion light-years from Earth. Using the LOFAR radio telescope network, which spans eight European countries, researchers detected a faint, diffuse glow—evidence of a giant cloud of high-energy particles and magnetic...

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...

Radio Signal from Early Universe May Reveal the Masses of the First Stars
A newly modelled 21-centimetre radio signal from hydrogen atoms just 100 million years after the Big Bang may reveal the mass of the universe’s first stars. Using REACH and the upcoming SKA telescopes, researchers aim to uncover how early starlight shaped cosmic evolution during the Cosmic Dawn, when the universe transitioned from darkness to lig...
