A team of astronomers led by the University of Victoria and Yale University has detected an ancient star system traveling around our galaxy named Ursa Major III / UNIONS 1 (UMa3/U1)—the faintest and lowest-mass Milky Way satellite ever discovered, and possibly one of the most dark matter-dominated systems known. The team conducted the study from … Read more
The prevailing theory of the universe’s composition, which includes dark matter as a major component, is facing a challenge from a new University of Ottawa study. Published in The Astrophysical Journal, the research suggests that the cosmos might not need dark matter at all. Traditionally, dark matter has been the invisible force used to explain … Read more
A new telescope called the “Condor Array Telescope” may open up a new world of the very-low-brightness universe for astrophysicists. Four new papers, published back to back in the Monthly Notices of the Royal Astronomical Society (MNRAS) this month, present the first scientific findings based on observations acquired by Condor. The project is a collaborative … Read more
Astronomers are currently enjoying a fruitful period of discovery, investigating the many mysteries of the early universe. The successful launch of the James Webb Space Telescope (JWST), a successor to NASA’s Hubble Space Telescope, has pushed the limit of what we can see. Observations are now entering the first 500 million years after the Big … Read more
Mummy Juanita, also known as the “Ice Maiden,” is one of the most significant archaeological discoveries in the Andes region and a poignant symbol of ancient Inca culture and religious practices. Discovered in 1995 on Mount Ampato in southern Peru by anthropologist Johan Reinhard and his team, Mummy Juanita captivated the world with her remarkably … Read more
The Lady of Cao, also known as the Lady of Cao Viejo, is an ancient Peruvian mummy who has emerged as a symbol of the rich cultural heritage and sophisticated civilization of pre-Columbian Peru. Her discovery in 2006 shed light on the powerful role of women in ancient Peruvian society and provided valuable insights into … Read more
Luminiferous aether, once proposed as the medium through which light waves propagate, represents a fascinating chapter in the history of physics. Despite being a prominent concept in the 19th century, subsequent scientific advancements have revealed its conceptual limitations and ultimately led to its dismissal. Exploring the origins, development, and eventual demise of the luminiferous aether … Read more
The Children of Llullaillaco, also known as the Llullaillaco Mummies, are three well-preserved Inca child mummies discovered on the summit of Mount Llullaillaco in the Andes Mountains of Argentina. This discovery has provided unique insights into the sacrificial rituals and religious beliefs of the Inca civilization. The story of these children, their lives, and their … Read more
Looking deep into space and time, two teams using the NASA/ESA/CSA James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old. Delivering on its promise to transform our understanding of the early universe, the James Webb Space Telescope is probing … Read more
European astronomers recently conducted extensive Very Long Baseline Interferometric (VLBI) observations on the radio jet structure of PKS 2215+020, a powerful quasar. The acquired VLBI data yielded crucial insights into the characteristics of this jet, indicating that PKS 2215+020 exhibits traits typical of a blazar. These findings, unveiled on February 17 in the Universe journal, … Read more
We now have a standard model of cosmology, the current version of the Big Bang theory. Although it has proved very successful, its consequences are staggering. We know only 5% of the content of the universe, which is normal matter. The remaining 95% is made up of two exotic entities that have never been produced … Read more
Using the powerful Magellan Telescopes in Chile, a team of Italian astronomers has turned their gaze toward the enigmatic giant galaxy cluster known as Abell 2744, affectionately dubbed the Pandora’s Cluster.

Redshift, a fundamental concept in astronomy and cosmology, serves as a cornerstone for understanding the universe’s vastness, expansion, and evolution. It represents a phenomenon where the light emitted by celestial objects, such as galaxies, stars, and quasars, is shifted towards longer wavelengths as they move away from an observer. This phenomenon, discovered over a century … Read more
Cosmic inflation is a theoretical framework in cosmology that describes a rapid and exponential expansion of the early universe during the first few moments (10^-36 to 10^-32 seconds) after the Big Bang.
