The Big Island summit of Mauna Kea recorded wind gusts of 191 mph (307 kph) late Sunday, the Hawaii Tribune-Herald reported .


On this edition of Bytemarks Café, Burt gets an insider’s view of NASA’s New Horizons flyby of Kuiper belt asteroid Ultima Thule. He’ll be joined by the Canada France Hawaii telescope personnel to find out how a telescope in Hawaii played a key role in locating and plotting a path to the asteroid.

  An international team of astronomers has discovered a new dwarf planet orbiting in a disk of small icy worlds beyond Neptune.  The new object is a little more than 400 miles wide and has one of the largest orbits recorded for a dwarf planet.  The small icy planet was spotted with the large camera at the Canada-France-Hawai‘i Telescope on Mauna Kea  as part of the ongoing Outer Solar System Origins Survey (OSSOS).
