Interstellar comet 3I/ATLAS formed in a deep-freeze environment near or below 30 kelvins, according to research led by Northumbria University scientists using the William Herschel Telescope. By analyzing the object’s plasma tail with the WEAVE instrument, researchers detected a high concentration of molecular nitrogen alongside four other ion species, offering an unprecedented look at planetary … Read more
According to research published in the Publications of the Astronomical Society of Japan, astronomers using the James Webb Space Telescope have identified four candidate pairs of “little red dots” in the early universe, providing new clues about how supermassive black holes grew rapidly just a billion years after the Big Bang. JWST Pixel-by-Pixel Analysis Reveals … Read more
Astronomers have discovered that star clusters do not always form with the same balance of small and large stars, challenging a foundational assumption used for more than half a century to measure galaxies, according to University of Missouri researchers who analyzed data from the European Space Agency’s Gaia mission. The finding shows that a key … Read more
According to research published in Physical Review D on July 16, 2026, Queen Mary University of London mathematician Professor Ginestra Bianconi has examined the thermodynamics of spacetime using the Gravity from Entropy (GfE) quantum gravity theory, revealing how total cosmic entropy increases while local entropy per unit volume declines as the universe expands. Reconciling Thermodynamics … Read more
According to general relativity framework observations, Albert Einstein introduced a cosmological constant in 1917 to counterbalance gravity and preserve a static universe model, a parameter later revived by astronomers in 1998 to explain the accelerating expansion of the cosmos driven by dark energy. General relativity originally described a dynamic cosmos expanding or contracting, yet prevailing … Read more
The observable universe is significantly larger than its age in light-years because space has continuously expanded while light travels toward Earth. While the universe is approximately 13.77 billion years old, the distance to the edge of the observable universe is roughly 45 billion light-years. This discrepancy exists because the expansion of space itself carries distant … Read more
When two black holes collide, they do not simply vanish into silence; they ring like a struck bell, shedding energy through gravitational waves in a process known as “ringdown.” According to a review, scientists are now using these fading vibrations to perform “black hole spectroscopy,” turning the aftermath of cosmic mergers into a precision laboratory … Read more
A decades-old mystery in particle physics has reached a turning point: a new study published in Physical Review Letters effectively rules out dark matter as the source of a long-standing “seasonal” signal. By combining data from the ANAIS-112 and COSINE-100 experiments, researchers have demonstrated that the annual modulation previously reported by the DAMA/NaI experiment does … Read more
New research suggests dark matter may not have required a cold, calm start to facilitate the formation of the universe. A study indicates that dark matter particles could have originated at near-light speeds—behaving as “hot” matter—before cooling sufficiently to seed the cosmic structures, such as galaxies, that we observe today. This finding challenges the four-decade-old … Read more
A new theoretical model suggests that collapsing massive stars may form “gravastars”—ultra-compact objects containing a mini-universe—rather than black holes. Published in Physical Review D by Daniel Jampolski and Professor Luciano Rezzolla of Goethe University Frankfurt, the research provides a dynamic solution to Albert Einstein’s equations of General Relativity, proposing that dark energy within a core … Read more
