A recent study investigates two enigmatic interstellar objects discovered through observations with the ALMA telescope (Atacama Large Millimeter/submillimeter Array) and the AKARI satellite. These bodies, hidden behind dense clouds of gas and dust, could represent a previously unknown type of interstellar object. The research, led by astrophysicist Takashi Shimonishi and his team, raises fundamental questions […]

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 […]
“Ancestral Disc” of the Milky Way Identified, Formed 13.5 Billion Years Ago
An international team of astronomers has identified and characterized the oldest disc in our galaxy, the Milky Way, which they have named PanGu. PanGu, whose name comes from Chinese mythology and literally means “ancient disc”, was formed more than 13.5 billion years ago, just a few hundred million years after the Big Bang. This discovery […]
Astronomers Discover Galaxy Being Devoured by a Supermassive Black Hole
A team of international researchers, co-led by the University of Cambridge, has used the powerful James Webb Space Telescope (JWST) to observe a galaxy from the early universe that is undergoing a dramatic transformation. Approximately the size of the Milky Way, this galaxy exists around two billion years after the Big Bang and hosts a […]
The Tired Light Theory and James Webb Telescope Observations Challenge the Validity of the Big Bang
A recent study by an engineer from Kansas State University offers new observational support for a century-old theory that directly challenges the validity of the Big Bang theory. Lior Shamir, an associate professor of computer science, used images from three different telescopes and data from over 30,000 galaxies to measure the redshift of galaxies in […]
Evidence Found for the Origin of Sagittarius A*, the Black Hole at the Center of the Milky Way
Supermassive black holes, celestial objects with masses greater than a million times that of the Sun, remain one of the greatest enigmas of the cosmos. These dark giants, located at the center of most galaxies, have an origin that has intrigued scientists for decades. Now, a team of researchers from the University of Nevada, Las […]
The Most Distant and Ancient Star Clusters Discovered Thanks to 5 Cosmic Gems Acting as Gravitational Lenses
An international collaboration, led by Ángela Adamo from Stockholm University and the Oscar Klein Centre in Sweden, has discovered five gravitationally bound star clusters in a galaxy whose light was emitted when the universe was only 460 million years old, thanks to observations from the James Webb Space Telescope (JWST – NASA/ESA/CSA). This discovery, published […]
Astronomers Detect Carbon in One of the Oldest Galaxies, an Essential Element for Life
In a study utilizing the James Webb Space Telescope (JWST), an international team of astronomers, led by the University of Cambridge, has observed a very young galaxy in the early universe, revealing surprising amounts of carbon. This discovery challenges current understanding of the formation and evolution of galaxies and the elements within them. In astronomical […]
