This week’s night sky offers highlights for stargazers from January 9–18. Vega twinkles in the northwest at dusk, while Algol dims on January 9. Jupiter reaches opposition on January 10, rising at sunset and dominating the night sky near Pollux and Castor, with Io disappearing and reemerging on January 13. The Great Orion Nebula, with variable star T Orionis, invites telescopic observation. Capella and the Kids sparkle in the east, and the winter Milky Way arches across the sky. Sirius shines below Orion, with the New Moon on January 18. Mercury, Venus, and Mars remain hidden; Saturn, Uranus, and Neptune are visible in evening skies. https://skyandtelescope.org/astronomy-news/observing-news/this-weeks-sky-at-a-glance-january-9-18/
