A young galaxy cluster spotted by the Chandra X-ray Observatory may have gotten a head start on “relaxing” before is galactic siblings.
With breakthroughs in astronomical observation, scientists now have confirmed the existence of supermassive black holes at the centers of galaxies. The recent release of black hole images has further charged people’s curiosity about black holes while providing additional evidence to support Einstein’s general theory of relativity.
These supermassive black holes range in mass from millions to billions of solar masses. Astonishingly, some of these black holes have formed less than a billion years after the Big Bang. Understanding how these black holes formed and grew to such enormous mass in such a short period of time has always been an important topic in modern astrophysics.
A research team composed of Chi-Hong Lin and Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) and Chorng-Yuan Hwang from the Institute of Astronomy at National Central University has made significant new advances in the formation theory of supermassive black holes. The research results have been published in The Astrophysical Journal.
Elon Musk recently stated SpaceX made ‘well over a thousand changes’ to Starship since its debut flight.
SpaceX continues to prepare for the second orbital launch attempt of Starship despite concerns over a potential delay caused by the ongoing environmental lawsuit against the Federal Aviation Authority (FAA).
Elon Musk’s private space company, likely eager to show that preparations continue uninterrupted, has shared a number of images on Twitter of Booster 9, the Super Heavy prototype that will be used for the massive rocket’s second test flight.
Worldcoin, a cryptocurrency project founded by OpenAI CEO Sam Altman, was launched today.
Worldcoin, an entity offering a World ID to distinguish earthlings from artificial intelligence, was launched Monday. The company rolled out an eyeball-scanning technology and a crypto token called WLD.
Co-founded by OpenAI CEO Sam Altman with Alex Blania three years ago, WorldCoin said it is looking to revolutionize digital identity. It’s designed by developers at Tools for Humanity (TFH). A user can use WorldCoin to authenticate their World ID to prove they are a real person and will receive the digital currency in their account, which they can send anywhere.

How useful a memory is for future situations determines where it resides in the brain, according to a new theory proposed by researchers at HHMI’s Janelia Research Campus and collaborators at UCL.
The theory, published in Nature Neuroscience, offers a new way of understanding systems consolidation, a process that transfers certain memories from the hippocampus —where they are initially stored—to the neocortex—where they reside long-term.
Under the classical view of systems consolidation, all memories move from the hippocampus to the neocortex over time. But this view doesn’t always hold up; research shows some memories permanently reside in the hippocampus and are never transferred to the neocortex.

Consciousness is what we can know best and explain least. It is the inner subjective experience of what it feels like to see red or smell garlic or hear Beethoven. Consciousness has intrigued and baffled philosophers. To begin, we must define and describe consciousness. What to include in a complete definition and description of consciousness?
NASA shares details about its Moon house and Mars module that will see astronauts spend more than a thousand days in space.
Researchers at the University of Texas at El Paso (UTEP) have created a supercapacitor with a record level of energy storage, marking a significant advancement in the field.
The first observation of neutrinos produced at a particle collider opens a new field of study and offers ways to test the limits of the standard model.
Neutrinos are among the most abundant particles in the Universe, but they rarely interact with matter: trillions pass through us every second, but most of us will never have even a single one interact with the matter in our bodies. Nonetheless, scientists can study these particles using high-intensity neutrino sources and detectors that are large enough to overcome the rarity of neutrino interactions. In this way, neutrinos have been observed from the Sun, from cosmic-ray interactions in the atmosphere, from Earth’s interior, from supernovae and other astrophysical objects, and from artificial sources such as nuclear reactors and particle accelerators in which a beam of particles hits a fixed target. But no one had ever detected neutrinos produced in colliding beams. This feat has now been achieved by the Forward Search Experiment (FASER), located at the Large Hadron Collider (LHC) at CERN in Switzerland [1].
As neutral particles, neutrinos cannot be directly observed by detectors of the kind used in particle colliders. Instead, scientists study neutrinos via the particles produced when incoming neutrinos interact with matter: the properties of the incoming neutrinos can be inferred from the measured properties of their interaction products. While these interactions are always rare, their probability increases with neutrino energy. In a particle collider, the highest energy neutrinos are most likely to be produced in a region of the collider where there are no particle detectors. Collider experiments are built to surround the colliding beams with detectors, with only a small central region left empty to allow for the entry and exit of the beams. It is in this empty “forward” region, along the collision axis, that the highest energy neutrinos are most likely to be produced.
