Strange Universe With Bob Berman

Time for something big

This week look for the Moon—and just to its left, you'll spot a bright, orange-red star: Antares. While most reddish stars in the universe are small and dim (like Proxima Centauri, our nearest stellar neighbor), Antares stands out as a red supergiant—huge and luminous. In fact, it's in a long-running rivalry with Betelgeuse over which is the biggest red star in the sky. We’re not exactly sure which one wins, but we do know Antares has a great name—meaning “rival of Mars” for its Mars-like glow. So step outside, take a look, and decide for yourself.

    On Sunday night, June 1, enjoy an easy and beautiful sky show: a crescent Moon pairs with two bright stars—one blue-white, one orange. The star just below the Moon is Regulus, the brilliant heart of Leo the Lion, once known as “Qalb” and later named by Copernicus. To the Moon’s right, the orange glow of Mars adds a planetary touch, though it’s dimmer now, sitting on the far side of its orbit. Look west anytime between nightfall and midnight for this celestial trio—no telescope needed.

    This month look up for a colorful celestial display! Just find the crescent moon in the western sky—sitting in a line with orange-hued Mars and pale blue Regulus, the brightest star in Leo. Together, they create a striking trio of white, orange, and blue—a patriotic parade in the night sky. Tune in to hear when the magic will happen.

    As we enter the moonless phase of the month — ideal for stargazing — it’s worth noting that even the darkest rural skies aren’t truly black. Natural skyglow, made up of airglow, Zodiacal Light, scattered starlight, and the unresolved shimmer of our galaxy, keeps the night subtly illuminated. During this period of solar maximum, the upper atmosphere glows more intensely, making the phenomenon even more striking. Despite urban light pollution, nature still puts on a quietly radiant show overhead.
