Three bright stars unlock the summer night sky

Space.com explains how the Summer Triangle—Altair, Vega and Deneb—serves as an easy anchor to learn the night sky this July: Altair is nearby (~17 light-years), Vega ~25 ly, and Deneb is extraordinarily distant (~2,600 ly). Spotting the triangle around 11 p.m. gives a mental map to the Milky Way, Cygnus, and surrounding regions, turning stargazing into a three‑dimensional exploration rather than a flat view. The piece also notes observing tips with binoculars or a telescope, mentions the Moon’s approach to Antares later in July, and points to nearby constellations Sagitta and Delphinus to help beginners map the sky by exploring regions instead of chasing individual objects.
