The moons were discovered by a team led by @epo_asiaa, using the @CFHTelescope in Hawaii. The team lead said "[t]here may be even more moons around Saturn awaiting discovery," but they'll be found by others. "I'm a bit mooned out at the moment." nytimes.com/2025/03/11/scien…

Tuesday evening our summit front door camera recorded a summit proposal. If the lucky couple is interested, we'd love to share the footage with them. It's a lot shot, but if anyone got engaged or know someone who did at the summit Tuesday, August 13th, let us know!

A year ago today, the fabric of Maui was forever altered by the devastating fires in Lahaina and Kula. 102 lives were lost and countless others changed in unimaginable ways. We remember them all today and urge you to do so as well. We send our aloha today and every day.

A team of astronomers used CFHT, @PanSTARRS1 and @keckobservatory to discover either the faintest, ancient cluster of stars to date or the faintest, closest know dwarf galaxy. There’s something like 60 stars in the object, given the beautiful name of UMa3/U1.

UMa3/U1 consists of stars that are more than 10 billion years old, twice the age of the sun and roughly two-thirds the age of the Universe . “It is either the faintest ancient star cluster known to date or the faintest and closest known dwarf galaxy ever discovered”–says Smith.
