Monday is the winter solstice, the longest night of the year. But this solstice brings with it a brilliant display of light, as Jupiter and Saturn draw close together in an event known as “the great conjunction.” They’ll appear closer in the sky than they’ve been in almost four centuries, low in the southwest after sunset. They may even look like a single dazzling star. KNAU’s Melissa Sevigny spoke with Lowell Observatory’s Kevin Schindler about how to see the once-in-a-lifetime event.

A year ago NASA’s New Horizons spacecraft flew past a strange snowman-shaped object in the Kuiper Belt, far beyond Pluto. Named Arrokoth, it’s the most distant object ever visited by a spacecraft.  Scientists say it’s offered up several surprises, including clues into how planets formed in the early days of the solar system. KNAU’s Melissa Sevigny spoke with Lowell Observatory’s Will Grundy about the new findings published in Science.

SpaceX launched 60 new Starlink satellites into orbit last week, in their quest to expand Internet access across the globe. The company hopes to have 1500 in orbit by the end of the year, and other companies are planning launches, too. That could mean tens of thousands of new satellites in the sky, which is bad news for astronomers. KNAU’s Melissa Sevigny spoke with Lowell Observatory director Jeff Hall about how these “satellite constellations” threaten astronomical research.

Melissa Sevigny: Are they brighter than the usual satellite up there?

Flagstaff’s Lowell Observatory will host a free open house tomorrow for its new plaza with six advanced telescopes. KNAU’s Melissa Sevigny reports, it’s part of an expansion planned through 2023.
