This week we explore both the night sky and the cosmic tick-tock of time itself. The Moon waxes from half-lit to nearly full, while Saturn shines golden in Pisces with its razor-thin rings. Jupiter and Venus rule the morning skies, and the faint Aurigid meteors and Comet Lemmon make cameo appearances for early risers.

In the second half of the show, we dive into the strange and fascinating world of “time in space.” From NASA engineers living on Martian sols with their custom-built Mars watches, to the Omega Speedmasters strapped to Apollo astronauts’ suits, to the atomic clocks aboard GPS satellites that literally rely on Einstein’s relativity to keep us from getting lost—this is a journey through the cosmic heartbeat that guides explorers and Earthlings alike.

This week we head outward to the seventh planet, where the James Webb Space Telescope has revealed a brand-new moonlet orbiting Uranus. Barely six miles across, this tiny world is so small you could, in theory, walk around it in a single day. But is “walking” even possible when the surface gravity is only a whisper? We run the numbers and explore what it would feel like to live in such a micro-gravity landscape, where a careless jump could fling you into orbit.

Back under Earth’s skies, the nights begin in darkness. The week opens with a fresh New Moon, offering deep-sky windows before the crescent brightens. Saturn dominates the evening hours, Venus and Jupiter rule the dawn, and the Aurigids meteor shower brings a chance of surprise streaks before sunrise. We’ll also shine a light on three quieter constellations — Lacerta the Lizard, Aquarius the Water-Bearer, and Capricornus the Sea Goat — exploring the lore behind their faint patterns and the clusters, doubles, and globulars tucked among their stars.

From new moons both near and far, to the myths written across our own skies, this is a week for patient eyes, and a reminder of how scale and story intertwine in the universe.

Under a rare seasonal Black Moon, this week’s sky rewards early risers and deep-sky wanderers alike. We start with a whisper-thin crescent slipping closer to the Sun each morning, then pivot to a dawn showcase where Mercury reaches greatest elongation while Venus and Jupiter stack higher above the horizon. On Tuesday and Wednesday a paper-thin crescent Moon joins the lineup—a perfect wide-field photo op—while evenings bring Saturn rising into prime viewing on its road to September opposition. With moonlight out of the way, scan the Milky Way for under-sung binocular treats: Delphinus the Dolphin, M11 (Wild Duck Cluster) in Scutum, and the Coathanger asterism in Vulpecula. You may even catch a few Perseid stragglers in the pre-dawn dark.

In the second half, we widen the frame to reveal the Milky Way’s “hidden companions”—dozens, maybe hundreds, of ultra-faint dwarf galaxies quietly orbiting our own. We unpack why they’re so hard to see (surface brightness, not just brightness), how modern surveys like SDSS and DES ferret them out, and why they matter for big questions about dark matter, galaxy growth, and the “missing satellites” problem.
