Researchers at the Research Center for the Early Universe (RESCEU) and the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) at the University of Tokyo have recently leveraged quantum field theory—traditionally applied to minute, subatomic phenomena—to explore the early universe. Their findings suggest that miniature black holes, specifically primordial black … Read more
An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Earth’s ionosphere. They have used the new method to study plasmas from ancient black hole bursts. Potentially, the … Read more
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe’s infancy, are revealing clues to how the very first black holes and galaxies evolved. Quasars are the blazing centers of active galaxies, which host an … Read more

The origin and evolution of the universe have fascinated humanity for millennia. Modern scientific theories, such as the Big Bang theory, provide a framework for understanding these cosmic processes. The universe began as an unimaginably dense and hot singularity around 13.8 billion years ago, expanding rapidly and cooling over time. Through cosmic inflation, galaxies, stars, … Read more
Quasars, short for “quasi-stellar radio sources,” are among the most enigmatic and fascinating objects in the cosmos. They are incredibly bright and energetic, emitting radiation across the entire electromagnetic spectrum, from radio waves to X-rays and gamma rays. Quasars are powered by the accretion of material onto supermassive black holes at the centers of galaxies, … Read more
Pulsars are cosmic lighthouses, beacons of intense radiation and magnetic fields that emit beams of light and other forms of electromagnetic radiation as they rotate rapidly. These exotic objects, often referred to as neutron stars, are the remnants of massive stars that have undergone supernova explosions. Pulsars were first discovered in 1967 by astrophysicist Jocelyn … Read more
Gravitational waves are ripples in the fabric of spacetime caused by the acceleration of massive objects, such as merging black holes or neutron stars. Predicted by Albert Einstein’s theory of general relativity in 1915, these waves were detected for the first time in 2015, marking a revolutionary breakthrough in astrophysics and opening a new window … Read more
Supernovae are some of the most powerful and cataclysmic events in the universe, representing the explosive deaths of massive stars and the birth of new cosmic phenomena. These cosmic explosions release vast amounts of energy and material into space, shaping the evolution of galaxies, enriching the interstellar medium with heavy elements, and producing some of … Read more
Embarking on a journey to the edge of the universe is an awe-inspiring concept that captures the imagination and curiosity of humanity. While our current technology limits our physical exploration to the confines of our solar system, the realms beyond hold mysteries and wonders waiting to be discovered. Our journey begins on Earth, our home … Read more
Stars are born and die in a continuous cycle, playing a fundamental role in the structure, dynamics, and evolution of the universe. The processes of star formation and stellar death are intricate and fascinating, involving a complex interplay of physical phenomena that span millions to billions of years. Understanding the birth and death of stars … Read more
Quantum mechanics is one of the most profound and revolutionary theories in modern physics, unraveling the mysteries of the subatomic world and fundamentally transforming our understanding of matter, energy, and the fundamental forces of nature.
