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.

Maunakea telescopes help detect ancient star system, Ursa Major III/UNIONS 1

An ancient star system has been detected with the help of two Maunakea observatories on Hawaiʻi Island – W. M. Keck Observatory and Canada-France-Hawaiʻi Telescope – and the University of Hawaiʻi Institute for Astronomy’s Panoramic Survey Telescope and Rapid Response System on Haleakalā, according to a Keck Observatory announcement.

Vast bubble of galaxies discovered 820 million lightyears away, given Hawaiian name

Astronomers from the University of Hawaiʻi have unexpectedly discovered an immense bubble of galaxies, named “Hoʻoleilana,” thought to be a fossil-like remnant from the birth of the universe.

Hawaiʻi’s Keck Observatory Aids in Discovery of Rare “Quadruply Imaged Quasars”

Machine-learning techniques led a team of astronomers to discover a dozen quasars that have been warped by a naturally occurring cosmic “lens” and split into four similar images. Quasars are extremely luminous cores of distant galaxies that are powered by supermassive black holes.

Astronomers Locate ‘Unusual’ Monster Galaxy

Maunakea scientists say the galaxy existed about 12 billion years ago, when the universe was only 13 percent of its current age.

Discovery by Hilo Alum Puts Einstein’s Theory to Test

The discovery paves the way for a big gravity test that could either prove Einstein’s Theory of General Relativity right or defy our current laws of physics.
