Subaru Telescope Spots a Planet in Formation

Using the Subaru telescope on Maunakea, astronomers have discovered a Jupiter-like planet in the process of being formed in another solar system. This ground-breaking experiment provides evidence for a long-debated alternative theory for how Jupiter-like planets form. Read more, in the Subaru Telescope web release.

MKOs Combine to Observe the Ruins of an Ancient Star Cluster

Astronomers have found the ruins of an ancient globular cluster in the outskirts of the Milky Way. Using the Canada-France-Hawaii and Gemini North telescopes on Maunakea, in conjunction with the Gaia satellite, they showed that the motions and compositions of stars in an outer-galaxy “stream” mean that it must have originated as a globular star cluster. In fact, this stream […]

Rogue Planets by the Hundred

Online viewers of the Subaru Telescope live stream were mesmerised by a cluster of more than a dozen meteors One Scouring through images from CFHT, Subaru and a number of other telescopes worldwide, an international team of astronomers has found the largest collection of free-floating “rogue” planets ever discovered, measuring their brightness, colour and miniscule motions across the sky. These […]

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 […]

A Crystal Ball Into Our Solar System’s Future

Astronomers using the Keck observatory on Maunakea have observed a planetary system located near the center of our Milky Way galaxy and provided a glimpse into the (distant) future of our own Solar System. Read more, in the W M Keck Observatory press release.

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 […]

Gemini North Identifies the Surprising Cause of a “Fizzled” Gamma-Ray Burst

Astronomers using the Event Horizon Telescope (of which two Maunakea observatories are a part) have zoomed into Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the Gemini North telescope on Maunakea, astronomers identified the cause of this 0.6-second flurry of gamma rays as a supernova explosion in a distant galaxy. GRBs […]

Zooming into the Heart of Centaurus A

Astronomers using the Event Horizon Telescope (of which two Maunakea observatories are a part) have zoomed into the heart of Centaurus A for the first time — at the center of which lies a black hole with the mass of 55 million suns. Read more, in the Submillimeter Array press release.

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 […]

New light on Pōwehi: Magnetic Fields at the Edge of M87’s Black Hole

Two Maunakea telescopes, the James Clerk Maxwell Telescope (JCMT), and the Submillimeter Array (SMA), have once again combined efforts with the global “Event Horizon Telescope” network to produce a view of Pōwehi, the Black Hole at the Center of the galaxy M87. The new results show the black hole in new light – specifically, polarized light. This enables astronomers, for […]

A Glimpse at the Infant Universe

Two Maunakea Observatories have been used to reveal the most distant – and therefore the youngest – known radio beacon in the early Universe. Seen as it was 780 million years after the big bang, the object – a quasar known as P172+18 – was originally discovered in images from the Pan-STARRS telescope on Haleakalā, Maui. Detailed study with the […]
