Astronomers and a team of data-sleuthing volunteers have discovered roughly 100 'cool worlds' near the Sun — objects more massive than planets but lighter than stars, known as brown dwarfs.
An international team of astronomers has discovered an immense structure beyond Laniakea, an immense supercluster of galaxies that includes our own.
"It is literally the greatest leap in humanity’s ability to study the Sun from the ground since Galileo’s time. It’s a big deal."
A University of Hawaii at Mānoa planetary scientistco-authored a study published this week in Science Advances that shows lava flows on Venus may be only a few years old, suggesting that Venus could be volcanically...
Astronomers now have a new pair of eyes to detect meteors over Hawaii using a state-of-the-art monitoring system installed on the rooftops of existing buildings on Maunakea and Haleakalā
The American Astronomical Society is holding their 235th meeting at the Hawaii Convention Center from January 4-8, 2020. Among the public events is a public talk titled, "The Physics of Pō." The talk...
Extrasolar planets are being discovered by the hundreds, but are any of these newfound worlds really like Earth? A planetary system recently discovered by the Kepler spacecraft will help resolve this question. The system of three planets, each just larger than Earth, orbits a nearby star called EPIC 201367065. The three planets are 1.5-2 times the size of Earth, and the outermost planet orbits on the edge of the so-called “habitable zone,” where the temperature may be just right for liquid water, believed necessary to support life, on the planet’s surface. “We’ve learned in the past year that planets the size and temperature of Earth are common in our Milky Way galaxy,” explains University of Hawaii astronomer Andrew Howard. “We also discovered some Earth-size planets that appear to be made of the same materials as our Earth, mostly rock and iron.”
