Is Space Sticky? New Study Challenges Standard Dark Energy Theory
New observations from the Dark Energy Spectroscopic Instrument are challenging the standard Lambda-CDM model of cosmology. A recent, still-unpublished hypothesis suggests that space itself may behave like a slightly viscous or “sticky” fluid, subtly affecting how the universe expands. By introducing a ghostly resistance to cosmic growth, the mo...

Hypothetical ‘Dark Stars’ Could Rewrite Early Cosmic History, Research Suggests
Hypothetical dark stars could explain three early universe mysteries: the abundance of supermassive black holes, dense blue monster galaxies, and compact little red dots. Powered by dark matter rather than fusion, these stars may have formed before normal stars, collapsing to create black hole seeds and influencing early galaxy observations, accord...

Physicists Deploy Quantum Sensors to Hunt the Universe’s Missing Matter
Dark matter makes up most of the universe’s mass, yet it has never been directly detected. Scientists are now deploying ultracold quantum sensors, underground detectors and space telescopes to catch its faint signals. At Texas A&M, new silicon detectors aim to register extremely rare particle interactions, while global experiments push sensitivit...

NASA Finds Most Distant Calm Galaxy Cluster Ever Seen in Early Universe
Astronomers using NASA’s Chandra X-ray Observatory have discovered SPT-CL J2215-3537, a massive galaxy cluster located 8.4 billion light-years away. Nicknamed the “Champagne Supernova” cluster, it is the most distant relaxed cluster ever observed, showing no signs of recent collisions. Its calm structure and active star formation challenge ex...

JWST Spots Most Distant Supernova Ever, From 730 Million Years After Big Bang
Scientists have confirmed the most distant supernova ever observed, exploding just 730 million years after the Big Bang. Detected through a powerful gamma-ray burst and later verified by the James Webb Space Telescope, the event offers a rare glimpse of the deaths of the universe’s first stars during the era of reionisation and challenges expecta...

Biggest Space Discoveries in 2025: From New Comets and Black Holes to Sign of Life on Mars
The year 2025 proved extraordinary for astronomy, delivering discoveries that stretched from our cosmic backyard to distant galaxies. Scientists tracked Comet 3I/ATLAS, only the third known interstellar object, while nearby stars like Barnard’s Star and Alpha Centauri revealed new planetary companions. On Mars, strange “leopard spots” raised ...

NASA Spots Starquakes in a Red Giant Orbiting One of the Galaxy’s Quietest Black Holes
A red giant star orbiting a quiet black hole spins faster than expected, while internal vibrations reveal it is younger than its ancient chemistry suggests. These findings hint at a past stellar merger and challenge existing models of star evolution in low-metal environments. Future observations aim to confirm its complex cosmic history.

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...

James Webb Space Telescope Could Illuminate Dark Matter in an Unexpected Way
New research suggests the James Webb Space Telescope could help uncover the true nature of dark matter. By observing strange, elongated galaxies in the early universe, scientists believe JWST may reveal how dark matter shaped cosmic structure, offering clues that could narrow down long-standing theories about this invisible substance.

Interstellar Comet 3I/ATLAS Nears Earth on Dec. 19, Offering Rare Insights Into Cosmic Visitors
Interstellar comet 3I/ATLAS will make its closest approach to Earth on Dec. 19. Observing the comet provides scientists a rare opportunity to study dust and gases from its icy nucleus and learn more about material forming around other stars, expanding understanding of interstellar objects while posing no threat to our planet.

Neutrino Detectors May Unlock the Search for Light Dark Matter, Physicists Say
Physicists now believe that massive neutrino detectors—built to observe rare solar and cosmic particles—could also detect extremely light dark matter that traditional experiments miss. By monitoring subtle annual variations in their background signals, observatories like JUNO and Borexino may open a new frontier in uncovering the universe’s m...

X-Ray Nebula Discovery Brings Astronomers Closer to Solving Cosmic Ray Mystery
A new study has linked an unexplained LHAASO detection to a pulsar-powered X-ray nebula, confirming it as a rare PeVatron capable of accelerating particles to extreme energies. The discovery is a major step toward solving the long-standing mystery of galactic cosmic rays. Researchers are now combining X-ray, gamma-ray and neutrino observations to t...
