Astronomers Make History in a Split Second
Maunakea, Hawaii – In a world first, an international team of astronomers has determined the precise location of a powerful one-off burst of cosmic radio waves. The discovery was made with CSIRO’s new Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope. The galaxy from which the burst originated was then imaged by three of the […]

Citizen Scientist Finds Ancient White Dwarf Star Encircled by Puzzling Rings
Maunakea, Hawaii – A volunteer working with the NASA-led Backyard Worlds: Planet 9 project has found the oldest and coldest known white dwarf — an Earth-sized remnant of a Sun-like star that has died — ringed by dust and debris. Astronomers suspect this could be the first known white dwarf with multiple dust rings. The star, named LSPM […]

Astronomers Uncover the Brightest Lensed Quasar in the Early Universe
Maunakea, Hawaii – Astronomers have discovered the brightest gravitationally lensed object ever seen at a time when the universe was less than one billion years old. With the help of multiple, world-class telescopes in Hawaii – Gemini Observatory, James Clerk Maxwell Telescope (JCMT), United Kingdom Infra-Red Telescope (UKIRT), and W. M. Keck Observatory on Maunakea, […]
