In a groundbreaking advancement for cosmology, an international team of researchers has obtained the sharpest image to date of a cosmic filament connecting two forming galaxies. This discovery, made after hundreds of hours of observation with the MUSE spectrograph at the Very Large Telescope of the European Southern Observatory (ESO) in Chile, allows for an […]

A Messenger from the Extreme Universe: First Ultra-High-Energy Neutrino Detected
In an unprecedented milestone for astrophysics, the cubic-kilometer neutrino telescope (KM3NeT), located in the depths of the sea, has detected a neutrino with an estimated energy of approximately 220 petaelectronvolts (PeV), equivalent to 220 million billion electronvolts. This extraordinary event, identified on February 13, 2023, by the KM3NeT ARCA detector, has been named KM3-230213A and […]
Astronomers Discover Inkathazo, an Intriguing Giant Galaxy 32 Times the Size of the Milky Way
Recently, a team of astronomers made an extraordinary discovery: a new giant radio galaxy (GRG) named Inkathazo, detected using the MeerKAT telescope located in South Africa. This cosmic structure, measuring an astonishing 3.3 million light-years from end to end, has captured the scientific community’s curiosity not only for its size but also for the peculiarities […]
Mysterious “Ghost Galaxies” Created at the Dawn of the Universe Stopped Forming Stars Millions of Years Ago
Astronomy, always seeking the deepest mysteries of the cosmos, has taken a significant new step with the discovery of three ultra-faint dwarf galaxies. This breakthrough, the result of collaboration between powerful telescopes in Chile and an international team of scientists, sheds light on events in the early Universe that influenced star formation in the smallest […]
Carbon atoms and other elements found to circulate in giant streams in the universe
Carbon, the building block of life on Earth, owes its existence to the fiery crucibles of stars. Alongside elements like oxygen and iron, carbon is forged in the intense nuclear reactions of stars and subsequently scattered across the universe when these stars meet their end in spectacular supernova explosions. These elements are not static wanderers […]
Scientists Claim Dark Energy does not Exist, and Accelerated Expansion of Universe is an Illusion Caused by Gravity slowing down time
For decades, dark energy has been one of the most enigmatic concepts in physics, introduced to explain the accelerated expansion of the Universe. This mysterious force, often described as an “antigravity” effect, was thought to make up approximately 70% of the Universe’s total energy density. However, new research challenges this assumption, proposing a groundbreaking explanation […]
New Observations from the James Webb Telescope Confirm There’s “Something” Accelerating the Universe’s Expansion, but We Don’t Know What It Is
New observations from the James Webb Space Telescope (JWST) delve into a mystery that has puzzled cosmologists for more than a decade: the so-called Hubble tension, which refers to the discrepancy between measurements of the universe’s current expansion rate and predictions based on standard cosmological models. These findings suggest that the faster expansion of the […]
Tiny Black Holes Created at the Beginning of the Universe Could Be Hiding in Hollow Planets, Rocks, and Ancient Buildings on Earth
Black holes result from the collapse of massive stars after they exhaust their fuel, creating regions of spacetime where not even light can escape. However, new research suggests that the chaos of the early universe might have generated black holes much smaller than those commonly known, referred to as primordial black holes (PBHs). These tiny […]
The Most Powerful Cosmic Rays Detected Come from Several Points Near Our Solar System
The universe is a stage filled with extreme phenomena, where temperatures and energies reach unimaginable levels. In this context, there are objects such as supernova remnants, pulsars, and active galactic nuclei that generate charged particles and gamma rays with energies far exceeding those involved in nuclear processes like fusion within stars. These particles, as direct […]
Scientists Discover that Dark Energy Density in the Universe Determines the Likelihood of Intelligent Life Existing
A recent study led by scientists from Durham University explores a fundamental question in cosmology: How does the density of dark energy affect the likelihood of intelligent life arising in the Universe? To answer this question, the researchers developed a theoretical model inspired by the famous Drake Equation, which examines the ideal conditions for star […]
