Maunakea telescope tunes into a stellar symphony of nearby star

Stars are not silent, and like musical instruments, stars resonate with natural frequencies that astronomers can “hear” with the right tools. Asteroseismology allows scientists to use these frequencies to probe the interiors of stars. 

Astronomers find evidence challenging conventional galaxy formation models

Astronomers using W. M. Keck Observatory at Maunakea on Hawaiʻi Island have found compelling evidence of a dark matter-deficient dwarf galaxy, FCC 224. The discovery challenges the traditional cosmological paradigm, which assumes dark matter is a fundamental component in galaxy formation.

Astronomers discover ancient star system orbiting around Milky Way using telescopes atop Mauna Kea

This system consists of just 60 stars that are over 10 billion years old, all bound by their own gravity and maybe even dark matter, according to a press release from the W.M. Keck Observatory.

Physics behind unusual behavior of stars’ super flares discovered

While solar flares can be powerful, they are insignificant compared to the thousands of “super flares” observed by NASA’s Kepler and TESS missions.

Vast bubble of galaxies discovered, given Hawaiian name

The entity has been given the name Hoʻoleilana, a term drawn from the Kumulipo, a Hawaiian creation chant evoking the origin of structure.

UH: Astronomers Trace Galaxy Flows

Everything in the universe moves, but the timescales needed to see motion are often vastly greater than human lifetimes.
