New Study Traces Io’s Volcanic Tides
Loki Patera, the major volcano on Jupiter’s moon Io, appears to wax and wane with an approximately 500-day oscillation in the moon’s orbit. Maunakea, Hawaii – Hundreds of volcanoes pockmark the surface of Io, the third largest of Jupiter’s 78 known moons, and the only body in our solar system other than Earth where widespread […]

Einstein’s General Theory of Relativity is Questioned But Still Stands ‘For Now’
Detailed UCLA-led analysis of the star’s orbit near supermassive black hole gives a look into how gravity behaves Maunakea, Hawaii – More than 100 years after Albert Einstein published his iconic general theory of relativity, it is beginning to fray at the edges, said Andrea Ghez, UCLA professor of physics and astronomy. Now, in the […]

Fast Radio Burst Pinpointed to Distant Galaxy
Maunakea, Hawaii – Fast radio bursts (FRBs) are among the most enigmatic and powerful events in the cosmos. Around 80 of these events—intensely bright millisecond-long bursts of radio waves coming from beyond our galaxy—have been witnessed so far but their causes remain unknown. In a rare feat, researchers at Caltech’s Owens Valley Radio Observatory (OVRO) […]

Spiraling Filaments Feed Young Galaxies
New data from W. M. Keck Observatory show gas directly spiraling into growing galaxies Maunakea, Hawaii – Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky. New observations, made using the Keck Cosmic Web Imager (KCWI) at W. M. Keck Observatory in […]

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 […]

Table Salt Compound Spotted on Europa
Maunakea, Hawaii – A familiar ingredient has been hiding in plain sight on the surface of Jupiter’s moon Europa. Using the Hubble Space Telescope to conduct a visible-light spectral analysis along with data taken from W. M. Keck Observatory on Maunakea in Hawaii, planetary scientists at Caltech and NASA’s Jet Propulsion Laboratory in Pasadena, California, […]

Maunakea Observatories Help Shed New Light on Obscured Infant Solar System
W. M. Keck Observatory and Subaru Telescope Data Taken Over Eight Years Solve Planet Formation Mystery Maunakea, Hawaii – Astronomers using the combined power of two Hawaii telescopes have taken groundbreaking, sharp new images of a distant planetary system that likely resembles a baby version of our solar system. Using Subaru Telescope and W. M. […]

Unusual Galaxies Defy Dark Matter Theory
Two New Studies Confirm That Galaxies Lacking Dark Matter Do In Fact Exist Maunakea, Hawaii – After drawing both praise and skepticism, the team of astronomers who discovered NGC 1052-DF2 – the very first known galaxy to contain little to no dark matter – are back with stronger evidence about its bizarre nature. Dark matter […]
