    The planet Venus has been especially prominent in the evening sky these past few weeks, joining Jupiter and a waxing moon in a sparkling, slow-motion dance of celestial bodies. On clear nights at the summit of Kilauea, this spectacle has complemented the other-worldly glow reflected by clouds above the lava lake in Halemaumau Crater.

    While the 1-year-old June 27 lava flow hasn’t threatened populated areas since March, geologists at the Hawaiian Volcano Observatory continue to study samples that might help fine-tune projections if it sends another 2,000-degree river of molten rock toward homes in lower Puna.
