An unprecedented collection of pulsating giant red stars has been identified by astronomers at the University of Hawaiʻi at Mānoa Institute for Astronomy (IfA).
Astronomers have discovered thousands of exoplanets—planets beyond our solar system—but few have been directly imaged, because they are extremely difficult to see with existing telescopes.
Jupiter’s icy moon Europa is of particular scientific interest because its salty ocean, which lies beneath a thick layer of ice, may currently have conditions suitable for existing life, and the ocean water may even make its way into the icy crust and onto the moon’s surface.
A new study by Institute for Astronomy (IfA) astronomers at the University of Hawaiʻi investigates a unique solar magnetic eruption observed during the 2020 total solar eclipse from Argentina.
These worlds, located in a planetary system 218 light-years away in the constellation Lyra, are unlike any planets found in our solar system.
Caught in an epic cosmic waltz, two supermassive black holes appear to be orbiting around each other every two years.
In 2020, the X-ray telescope eRosita took images of two enormous bubbles extending far above and below the center of our galaxy.
Almost all of the planets discovered to date (including the solar system planets) are confined to the plane of the Milky Way, and are unable to glimpse a sweeping vista of our galaxy
From centuries of studying the planets within our solar system, astronomers have wondered how planets form and evolve to become the ones we observe today.
The Kuiper Belt is a massive disk of icy bodies, including Pluto, that is located just outside of Neptune’s orbit in our solar system.
Mysteries have swirled around the origin of interstellar object ʻOumuamua since astronomers on Haleakalā first discovered it in 2017 with the University of Hawaiʻi Pan-STARRS1 (Panoramic Survey Telescope and Rapid Response System) telescope
Searching through existing data spanning 9 billion years, a team of researchers led by scientists at University of Hawaiʻi at Mānoa has uncovered the first evidence of “cosmological coupling”—a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe.
Earth is constantly being bombarded by meteorites—from nearly invisible, dust-sized particles to large impactors that have changed the trajectory of life on our planet.
How old is our universe, and what is its size? A team of researchers led by University of Hawaiʻi at Mānoa astronomers Brent Tully and Ehsan Kourkchi from the Institute for Astronomy have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4
What does our universe look like at the largest size scales? A team of researchers from the University of Hawaiʻi Institute for Astronomy (IfA) and Eötvös Loránd University in Hungary has produced a massive new catalog of high-fidelity distance estimates to more than 350 million galaxies, revealing the soap-bubble structure of the universe in detail.
An international team led by Stefan Pelletier, a Ph.D. student at Université de Montréal's Trottier Institute for Research on Exoplanets announced today having made a detailed study of the extremely hot giant exoplanet WASP-76 b.
There’s an intriguing exoplanet out there – 400 light-years out there – that is so tantalising that astronomers have been studying it since its discovery in 2009.
A large international team led by astronomers at the Trottier Institute for Research on Exoplanets at Université de Montréal (UdeM) today announced in the journal Nature the discovery of a new temperate world around a nearby small star.
