Cosmology is the scientific study of the large-scale properties of the universe as a whole. It aims to understand the origin, evolution, structure, and eventual fate of the universe. By examining cosmic phenomena such as the Big Bang, cosmic microwave background radiation, dark matter, and dark energy, cosmologists develop theories and models that explain how … Read more
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
The search for gravitational lenses is a fascinating endeavor in astronomy and cosmology that has revolutionized our understanding of the universe’s structure, composition, and evolution. Gravitational lenses are cosmic phenomena predicted by Einstein’s general theory of relativity, where the gravitational field of massive objects, such as galaxies or galaxy clusters, bends and distorts the paths … Read more
Artificial Intelligence (AI) is revolutionizing the field of astronomy by enabling new approaches to data analysis, pattern recognition, and knowledge discovery. From processing vast amounts of observational data to enhancing simulations, AI techniques are enhancing our understanding of the universe and accelerating scientific discoveries. The role of AI in astronomy encompasses a wide range of … Read more
The dance of galaxies in the cosmic web is a mesmerizing spectacle of cosmic structure and evolution, revealing the intricate interplay of gravity, dark matter, and cosmic forces shaping the large-scale distribution of galaxies in the universe. The cosmic web is a vast network of filaments, voids, and clusters that connect galaxies across cosmic distances, … 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
Exoplanets, or extrasolar planets, are celestial bodies that orbit stars outside our solar system. These distant worlds have captivated the imagination of scientists and the public alike, offering tantalizing glimpses into the diversity of planetary systems beyond our own. The study of exoplanets has revealed a wealth of wonders, from rocky worlds resembling Earth to … Read more
Recent discoveries in space science have unveiled intriguing insights into the early dynamics of our solar system, shedding light on the formation of celestial bodies like our moon. A team of space scientists led by the University of Leicester has unearthed evidence from the remnants of a destroyed asteroid, hinting at a crucial period in … Read more
In the constellation Virgo, 700 light years away from Earth, the planet WASP-39b orbits the star WASP-39. The gas giant, which takes little more than four days to complete one orbit, is one of the best-studied exoplanets. Shortly after its commissioning in July 2022, NASA’s James Webb Space Telescope turned its high-precision gaze on the … Read more
When it comes to nurturing their young, mother chimpanzees go the extra mile, according to a new study. Using 10 years of observational data on wild chimpanzees, researchers found that while adults often play, and young chimps play a lot, when food gets scarce, the adults put mutual play aside and focus on survival. But … Read more
Using the powerful Canada France Hawaii Telescope (CFHT), a team of Chinese astronomers has embarked on a captivating journey into the heart of a merging dwarf galaxy, shedding light on its enigmatic nature. Their findings, presented on March 4 via the arXiv preprint server, provide crucial insights into the dynamics and characteristics of this intriguing … Read more
Betelgeuse is a well-known red supergiant star in the constellation Orion. Recently it has gained a lot of attention, not only because variations in its brightness led to speculations that an explosion might be imminent, but also because observations indicated that it’s rotating much faster than expected. This latter interpretation is now put into question … Read more
Will ice floating in the Arctic Ocean move faster or slower over the coming decades? The answer to this question will tell us whether marine transportation can be expected to get more or less hazardous. It might also have important implications for the rate of ice cover loss, which is hugely consequential for Northern Indigenous … Read more
