Sun Erupts with Powerful Solar Flare, Sending Plasma Toward Earth
The Sun unleashed an M5.7-class Solar Flare on May 10, 2026, disrupting high-frequency radio communications and launching a coronal mass ejection toward Earth. Scientists predict the incoming plasma could trigger a minor geomagnetic storm and brighten auroras across northern regions. The event highlights the Sun’s increasing activity as it approa...

Astronomers Detect Massive 'Cosmic Laser' 8 Billion Light-Years Away
Astronomers using MeerKAT have detected the most distant and powerful "cosmic laser" ever observed, offering new insights into galaxy mergers and the early Universe.

NASA Juno Mission Uncovers Subtle Geometric Shifts That Challenge Existing Models of the Jovian Interior
Scientists have refined Jupiter’s size and shape using modern radio signal observations, finding the giant planet slightly smaller and more flattened than earlier estimates. Though the difference is only a few kilometres, researchers say it greatly improves models of Jupiter’s interior, gravity, and atmospheric structure, offering deeper insigh...

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...
