Astronomers using the Subaru Telescope captured a multi-wavelength image of interstellar comet 3I/ATLAS (C/2025 N1) in December 2025, revealing its chemical and physical properties and offering new insights into how planetesimals and planets may form in distant star systems.
Astronomers studying SN 2022esa with the Subaru and Seimei telescopes found a stable, month-long periodicity before the explosion, consistent with a Wolf-Rayet star in a binary system and a companion that may become a black hole or a massive star. The event could mark the birth of a black-hole binary, providing new insights into how such systems form; results were published in Physical Review Letters.
A UCLA-led team has used a novel optical fibre device called a photonic lantern on the Subaru Telescope to achieve record-breaking resolution, revealing unprecedented details of a star's surrounding gas disc and demonstrating a new method to study celestial objects with greater clarity than traditional techniques.
Using the Subaru Telescope and the James Webb Space Telescope, astronomers discovered seven dust-shrouded supermassive black hole-powered quasars from when the universe was less than a billion years old, suggesting that such quasars may be twice as common during Cosmic Dawn as previously thought.
The Subaru Telescope discovered a new distant object, 2023 KQ14, classified as a sednoid, which provides new insights into the complexity and history of the outer solar system and challenges existing theories about Planet Nine.
Astronomers have captured the first direct image of GJ504b, a distant exoplanet dubbed the 'second Jupiter,' using advanced technology on the Subaru Telescope. Located 60 light-years away, this planet is notable for its size, cold temperature, and clear atmosphere, providing valuable insights into planetary formation and atmospheric characteristics. This breakthrough highlights the potential of modern observational tools in exploring distant worlds.
Astronomers using Japan's Subaru Telescope have discovered a rare triple-ring galaxy 800 million light-years away, challenging existing galaxy classification systems like the Hubble sequence. The formation of ring galaxies remains a mystery, with theories suggesting they result from galactic collisions or resonance phenomena. This discovery could lead to a better understanding of galactic formation and evolution.
Citizen scientists and AI have discovered 430,000 galaxies, including 30,000 rare ring galaxies, using data from the Subaru Telescope. The "GALAXY CRUISE" project involved 10,000 volunteers and AI to sift through the telescope's massive data. The AI classified 400,000 galaxies as spiral and 30,000 as ring galaxies, shedding light on the rare galaxy type's formation and demonstrating the power of AI in astronomical data analysis.
Using the Subaru Telescope, astronomers discovered three new moons orbiting Uranus and Neptune, with one around Uranus and two around Neptune. One of the new moons, S/2021 N1, is the faintest moon ever discovered by ground-based telescopes. The discoveries provide insights into the early solar system's history and the movement of planets on its outer edges, shedding light on the capture of outer moons and the chaotic nature of the early solar system.
Astronomers have detected dark matter hanging from massive filaments in the cosmic web for the first time using the Subaru Telescope, indirectly observing dark matter on cosmic web filaments in the Coma Cluster. This discovery could help confirm how the cosmic web has influenced the universe's evolution, and the team's results were published in the journal Nature Astronomy.
Astronomers have detected dark matter hanging from massive filaments in the cosmic web for the first time using the Subaru Telescope, marking the first-ever observation of dark matter on the cosmic web. This discovery in the Coma Cluster, a collection of over a thousand galaxies, could provide insights into the influence of the cosmic web on the universe's evolution. By utilizing gravitational lensing, the team observed a weak lensing effect of the dark matter component of intracluster filaments, confirming the existence of the large-scale structure spreading across the universe.
Astronomers using the Subaru Telescope have directly detected Dark Matter filaments in the massive Coma Cluster, providing new evidence for the structure of the Universe. These filamentary structures, spanning millions of light years, were observed for the first time, offering a means to test cosmological theories and understand the evolution of the Universe.
The Subaru Telescope has directly detected the terminal ends of dark matter filaments in the Coma cluster, providing the first evidence of the cosmic dark matter web spanning millions of light years. This discovery offers new insights for testing theories about the evolution of the universe and was made possible by the telescope's high sensitivity, resolution, and wide field of view. The findings, published in Nature Astronomy, confirm the existence of invisible dark matter filaments attached to the Coma cluster, shedding light on the structure of the universe.
Analysis of extremely red objects (EROs) discovered in James Webb Space Telescope (JWST) data reveals that they are similar to blue-excess dust obscured galaxies (BluDOGs) already reported in Subaru Telescope data. EROs and BluDOGs are likely the same class of objects, but with some important differences. Further research is needed to determine the true relationship between EROs, BluDOGs, and quasars. A larger sample of candidates will be studied using the next generation of astronomy instruments, including the planned infrared space telescope project GREX-PLUS.
A star named S0-6, located near the center of the Milky Way, is believed to have originated from a galaxy that no longer exists. This interloper star could have traveled over 50,000 light years to reach the supermassive black hole at the heart of our galaxy. The star's composition suggests it came from smaller galaxies outside the Milky Way. This discovery could help explain the mystery of how stars near the black hole are formed. Further investigation will be conducted to confirm the star's origin and determine if it traveled alone or with companions.
