Latest Episodes
  • When we gaze at the Moon in the future, we’ll contemplate that we humans have extended our reach to Earth’s nearest celestial neighbor. Perhaps this will be our first step toward making human life interplanetary.
  • Let’s hope for clear skies on the morning of March 3, when the Western Slope will be treated to a total lunar eclipse. During the early hours of March 3, the Moon will move through Earth’s shadow, creating one of the more eerie sights in nature.
  • Who doesn’t like a pretty cloud in the sky? As familiar as the Sun and the Moon, clouds assume a wide array of shapes and sizes—from ominous cumulonimbus to cottony altocumulus, feathery cirrus to leaden stratus, and various hybrids in-between. We see them year-round worldwide, boding fair and foul weather alike.
  • How did life originate? Did it form on Earth or elsewhere in the solar system and was it seeded on Earth by impact of an asteroid? Will life eventually be wiped out by an asteroid? While we may never know the answers to these questions, scientists are attempting to study as much as possible about the origins of life and the possibilities of future asteroid collisions with the Earth.
  • On a clear night if you look in the sky towards true north, you’ll notice a star that seems to never change direction. If you’re able to find this star, it is called Polaris.
  • An article in the international journal Nature Cities by Lvlv Wang and co-authors document the effect of light pollution on the growing season in 428 Northern Hemisphere cities between 2014 and 2022. They note that the typical growing season is controlled by heat and light. While cities are getting warmer due to climate change, they are also getting brighter due to excessive lighting. After controlling for the warming effect, they found that the excessive light was extending the growing season.
  • The unappreciated dung, or scarab beetle, an insect that evolved about 130 million years ago, must accomplish its nocturnal task under increasingly difficult conditions; chief among them, light pollution.
  • Awe, as researchers Maria Monroy and Dacher Keltner explain, is a transformative emotion. It soothes your nervous system, quiets self-doubt, fosters kindness, builds connection, and gives life meaning. Under a starry sky, awe feels like the universe reaching out, reminding you that you’re part of something greater, never truly isolated.
  • Have you noticed fewer insects around your porch light or fewer splattered bugs on your windshield? You're not alone. Scientists are calling this a new crisis—the "insect apocalypse"—and artificial light at night is a major cause.
  • We know that waterfowl like geese migrate at night, but did you know that songbirds do too? Beneath Western Colorado’s vast, star-strewn skies, migratory birds like Warbler’s, and Swainson’s Thrush embark on a breathtaking odyssey, their wings slicing through the night during peak migrations in May and September, from 10 p.m. to 2 a.m.
