WATCH: ‘Superkilonova’; a star so nice, it explodes twice
A team of astronomers using a variety of telescopes — including W. M. Keck Observatory atop Mauna Kea on the Big Island — seem to have discovered a possible “Superkilonova,” or a kilonova spurred by a supernova that forms a pair of dense, dead stars called neutron stars than then smash together.
Keck Observatory observes first gravitationally lensed superluminous supernova
Astronomers have discovered the first-ever spatially resolved, gravitationally lensed superluminous supernova. The object, dubbed SN 2025wny, offers a rare look at a stellar cataclysm from the early Universe and provides a striking confirmation of Einstein’s theory of general relativity. The discovery relied on a chain of cutting-edge observatories collaborating on scientific breakthroughs.
UH astronomer helps capture shape of Supernova explosion as massive star dies
Astronomers have captured one of the universe’s most dramatic moments – the instant a massive star exploded and the blast broke through the star’s surface. A University of Hawaiʻi astronomer was part of the international team that raced to record and study the supernova in real time.
Keck Observatory helps unravel mystery behind rare cosmic X-ray bursts
An international team of astrophysicists using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have uncovered a possible origin of fast X-ray transients (FXTs) — mysterious, fleeting bursts of X-rays that have long puzzled astronomers.
Mauna Kea’s Keck Observatory plays key role in mapping one of five supernovae ever seen from Earth
A Caltech-led team using W. M. Keck Observatory on Mauna Kea, Hawaiʻi Island has mapped in 3-D the remains of a historical supernova that went boom in the year 1181 – it’s one of only five confirmed supernovae in our Milky Way galaxy ever seen from Earth and recorded in human history.
Researchers work to unlock secrets of supernovae, exploding stars
Using multiple telescopes, researchers from the Weizmann Institute of Science are working to understand supernovae, exploding stars, dating back millions of light-years and considered the building blocks of the universe and life itself.
Maui’s Pan-STARRS telescope helps log largest catalog of exploding stars
The Pan-STARRS telescope atop Haleakalā on Maui has collected data that is now being released as the largest catalog of exploding stars. The data from the University of Hawaiʻi Institute for Astronomy’s Pan-STARRS telescope contains three years of research and is now publicly available via the Young Supernova Experiment.
