Observations from the James Clerk Maxwell telescope and the Submillimeter Array, both located on Maunakea, contributed to the production of the first-ever image of the shadow of the black hole at the heart of the Milky Way galaxy, by the “Event Horizon Telescope”. This incredibly challenging observation builds on the more than 20-year history of studies of the Galactic Center […]
Using the Subaru telescope on Maunakea, astronomers have discovered a Jupiter-like planet in the Three Maunakea telescopes (Subaru, CFHT and Gemini) played key, complementary parts in capturing the first ever images of a rocky comet (named 323P/SOHO) breaking apart close to the Sun. This helps to explain why so few near-Sun comets are observed. Read Read more, in the Subaru […]
Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Using observations with the Gemini North telescope and NASA Infrared Telescope Facility on Maunakea, and the Hubble Space Telescope in orbit, researchers developed a single atmospheric model that matches observations of both planets. The model reveals that excess haze on Uranus builds up in the planet’s […]
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.
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 […]
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 […]
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 […]
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.
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 […]
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 […]
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.
“We are normal!” - After thirty years of observational work, largely from Maunakea, astronomers reveal that the gas giant planets in many other solar systems lie at about the same distance from their stars as Jupiter does in our own solar system.
