Observatories Assemble: NASA’s Juno Spacecraft Joins W. M. Keck Observatory and Japan’s Hisaki Satellite to Solve “Energy Crisis” on Jupiter
Maunakea, Hawaiʻi – Sitting more than five times the distance from the Sun as Earth, Jupiter is not expected to be particularly warm. Based on the amount of sunlight received, the average temperature in the planet’s upper atmosphere should be about minus 100 degrees Fahrenheit or a chilly minus 73 Celsius. Instead, the measured value […]

Astronomers Probe Layer-Cake Structure of Brown Dwarf’s Atmosphere
Maunakea, Hawaiʻi – Jupiter may be the bully planet of our solar system because it’s the most massive planet, but it’s actually a runt compared to many of the giant planets found around other stars. These alien worlds, called super-Jupiters, weigh up to 13 times Jupiter’s mass. Astronomers have analyzed the composition of some of […]

Teardrop Star Reveals Hidden Supernova Doom
Maunakea, Hawaiʻi – Astronomers have made the rare sighting of two stars spiraling to their doom by spotting the tell-tale signs of a teardrop-shaped star. The tragic shape is caused by a massive nearby white dwarf distorting the star with its intense gravity, which will also be the catalyst for an eventual supernova that will […]

A White Dwarf Living on the Edge
Astronomers Have Identified A White Dwarf So Massive That It Might Collapse Maunakea and Haleakala, Hawaiʻi – Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is heavy, “packing a mass greater than that of our Sun into a body […]

New, Third Type of Supernova Observed
Maunakea, Hawaiʻi – An international team of astronomers has captured the very first evidence of a new type of supernova. The discovery confirms a prediction made four decades ago and could lead to new insights into the life and death of stars. It also sheds new light on the thousand-year mystery of the supernova that […]
