Scientists Solve Mystery Of Puzzling Radio Pulses From Space
Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since their discovery in 2022. Our new study, published in Nature Astronomy today, might finally add some clarity.

Astronomers Solve the Mystery Behind M87’s Enormous Space Jet
Astronomers have directly linked the supermassive black hole M87* to its enormous plasma jet using new Event Horizon Telescope data. The findings reveal where the jet originates near the black hole’s shadow, providing crucial insight into how black holes launch matter at nearly the speed of light.

Scientists Study 100 Possible Alien Signals as Arecibo’s Historic SETI Search Concludes
Scientists are studying 100 possible alien radio signals identified from Arecibo Observatory data, bringing the 21-year SETI@Home project to a close. Supported by millions of volunteers, the effort found no confirmed alien messages but set new sensitivity standards. Researchers say the findings will guide future searches using more powerful radio t...

Rare Interstellar Object 3I/ATLAS Fails Alien Test, Scientists Say
The most sensitive radio search ever conducted on interstellar object 3I/ATLAS has found no signs of alien technology. Using the Green Bank Telescope, scientists scanned key radio bands during its closest approach to Earth. All detected signals were linked to interference, strengthening the view that 3I/ATLAS is a natural object.

Astronomers Observe Black Hole Twisting Spacetime for the First Time, Confirming Einstein’s Theory
Astronomers have directly observed a black hole twisting spacetime for the first time, confirming Einstein’s long-standing prediction. The effect was detected during a violent stellar destruction event, where repeating X-ray and radio signals revealed a slow cosmic wobble. The discovery provides new insight into black hole spin, jets, and extreme...

Indian Team Finds 53 Massive Quasars Blasting Jets Millions of Light-Years Long
Astronomers in India have identified 53 previously unknown giant radio quasars powered by supermassive black holes, each releasing enormous plasma jets reaching up to 7.2 million light-years—nearly 50 times the Milky Way’s diameter. Using GMRT data, the team expanded the catalog of known giant quasars and offered valuable clues about how black ...

How Hot Was the Universe 7 Billion Years Ago? Scientists Now Have an Answer
Japanese astronomers using ALMA data have found the universe was about twice as hot 7 billion years ago, with a temperature of 5.13 K compared to today’s 2.7 K. The finding aligns perfectly with Big Bang predictions that the Universe cools as it expands, providing the most precise mid-epoch measurement yet and reinforcing confidence in standard c...

Astronomers Discover Most Distant And Powerful Odd Radio Circle In The Universe
A rare discovery in deep space has stunned astronomers: twin radio rings surrounding a galaxy about 7 billion light-years away. Known as an odd radio circle (ORC), this is the most distant and powerful ever found. Citizen scientists first spotted it, and LOFAR confirmed its existence, opening new insights into galactic and black hole evolution.

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...

Twisted Jet Confirms Most Extreme Binary Black Hole System in the Universe
Astronomers have confirmed that the blazar OJ 287 hosts the most extreme binary black hole system ever found. Using a global radio telescope array, they captured an ultra-sharp image showing a dramatically bent jet—evidence of two supermassive black holes locked in orbit. The system’s 12-year flare cycle and jet twists match predictions of a sm...

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...

PSR J0922+0638 Pulsar Keeps Glitching Every 550 Days, Scientists Are Intrigued
PSR J0922+0638, an ultradense neutron star, shows puzzling rotational glitches every 550 days. Using 22 years of radio data, scientists detected both abrupt and slow changes in its spin. These may be linked to magnetic field cycles or superfluid dynamics deep inside the star. However, the exact cause remains a mystery, demanding continued long-term...

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.

Astronomers Discover a Gigantic Supernova Remnant in the Large Magellanic Cloud
Veliki is a newly discovered, massive supernova remnant in the Large Magellanic Cloud, observed through a global collaboration using multiwavelength astronomy tools. Estimated to be 45,000 years old, Veliki showcases complex shell structures and highly unusual radio properties.

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...
