Infant Planet Discovered using Maunakea Telescopes

Online viewers of the Subaru Telescope live stream were mesmerised by a cluster of more than a dozen meteors One of the youngest planets ever observed around a distant star was recently discovered by an international team of scientists, using the Subaru and Keck observatories on Maunakea. The planet is several million years old, which is as young as the […]

Subaru Telescope Captures a Rare Meteor Cluster

Online viewers of the Subaru Telescope live stream were mesmerised by a cluster of more than a dozen meteors streaking across the dark Maunakea sky in quick succession, in the early hours of July 14th. The objects were also captured by the University of Hawaii’s all-sky camera on Haleakalā. The video is now being analyzed in detail by researchers. Read […]

Night and Day, a Live Stream of the Sky from Subaru Telescope

Subaru telescope now live streams a section of the eastern sky from Maunakea via the YouTube channel of Asahi Space Club. This is in collaboration with the Asahi-Shimbun, one of the most popular newspapers in Japan. The camera streams its images both night and day; at night, it’s a good place to watch for meteors and other celestial events. Read […]

Subaru Telescope Observes a Comet Nucleus Covered in “Talcum Powder”

Astronomers using the Subaru Telescope on Maunakea have measured the characteristics of mid-infrared light from an old comet nucleus. The comet, originally detected by the Pan-STARRS survey telescope on Haleakalā, passed quite close to the Earth and the team managed to observe it just a day before its closest approach. Besides measuring the size of the nucleus (about half a […]

Farfarout is Indeed Far, Far Out

Thanks to observations with the Subaru and Gemini North telescopes both on Hawaii’s Maunakea, astronomers have confirmed that a faint object discovered in 2018 and nicknamed “Farfarout” is indeed the most distant object yet found in our Solar System. Farfarout was first spotted in January 2018 by the Subaru Telescope and the discoverers could tell it was very far away, […]

Subaru Telescope Charts a Course to a Close-passing Asteroid

The Subaru Telescope on Maunakea recently captured images of the asteroid 1998 KY26, which travels close to Earth only once every 3.5 years. This asteroid is small, just 30 meters (less than 100 ft) across, so it is faint enough that most ground based telescopes can’t even detect it. Importantly, 1998 KY26 is the next target for the Japan Aerospace […]

New Instrument on Maunakea Telescope Nets its First Discovery

Subaru Telescope has a new state-of-the-art instrument, SCExAO/CHARIS, and it has made its first discovery. SCExAO/CHARIS is devoted to imaging and study of planets orbiting stars beyond our solar system (known as “exoplanets”). A team of astronomers have recently used this new instrument to identify an exoplanet, named HD 33632 Ab, orbiting a 1.5 billion year-old star similar to our […]

Observing Clusters of Galaxies Collide

Using a trio of world-leading observatories, including the Subaru Telescope on Maunakea, astronomers have observed clusters of galaxies colliding in the distant Universe. The Subaru telescope can observe the visible light from stars, but these galaxies also have other important components, including dark matter and hot gas, which can’t be seen with visible light. So the astronomers combined visible, radio, […]

Galaxies in the Infant Universe were Surprisingly Mature

An international team of astronomers have performed the largest survey of distant galaxies in the early universe ever conducted. This survey (nicknamed ALPINE) aimed at measuring the gas and dust in over 100 distant galaxies located over 12 billion light years away from Earth, and involved the use of two Maunakea Observatories — W. M. Keck Observatory and Subaru Telescope. […]

Astronomers Discover New Information about the Evolution of Planetary Systems

A team of astronomers have used the Subaru Telescope, located on the slopes of Maunakea, to precisely measure the dynamics of two young planets outside our solar system. Each of these planets are about the size of Neptune, and are currently in the early stages of formation. To date, the search for planets orbiting stars other than our Sun (known […]

Rare Encounters Between Cosmic Heavyweights

A combination of three Maunakea observatories (Keck, Subaru and Gemini) has been used by a team of Astronomers to discover several pairs of merging galaxies. In our dynamically evolving Universe, galaxies experience collisions and mergers with other neighbouring galaxies. These rare events can be dramatic, causing the birth of new stars and the rapid feeding of the supermassive black holes […]

Using Artificial Intelligence to Classify Galaxies in our Universe

A group of astronomers have used state of the art artificial intelligence algorithms to classify more than half a million galaxies in images obtained with the Subaru Telescope located on the slopes of Maunakea. About 100 years ago, the American astronomer Edwin Hubble discovered that various types of galaxies exist in our Universe, from beautiful spiral galaxies to smooth elliptical-shaped […]
