Maybe I missed something in school, but for a long time I couldn't understand why meteor showers like the Perseids occur at exactly the same time every year. Surely a global cosmic phenomenon can't be so perfectly synchronized with our calendar? It turns out it's simple. There are comets whose orbits intersect with Earth's orbit. These comets once passed through there, and their traces remain. Every year, Earth passes through the same "trail" of particles left by a comet. These microscopic fragments enter our atmosphere and burn up, creating beautiful "star showers." The Geminids, Perseids, and other meteor showers work in exactly the same way—each of these "trails" is associated with its own celestial body. Today's guest, astronomer Stanislav Korotky, explained this to me.

We discussed why the northern lights are most often green, what other colors they can be, and why they are sometimes visible even in cities. We discussed rare phenomena like a triple eclipse of Jupiter's moons, the darkest lunar eclipse of the next century, and the mysterious Tabby's Star, which unexpectedly fades in brightness, baffling astronomers.

We also discussed how astrophotography differs from regular photography, why amateurs "save" light for tens of hours to photograph a nebula, and whether it's true that only a few photons reach us. Can you see a supernova with the naked eye? Are there stars that explode twice? Is it possible to capture something cosmic with a regular smartphone?

This episode explores how the familiar starry sky hides a multitude of astonishing phenomena—from comet dust particles to the explosions of entire stars. How much beauty there is in the sky above us, and how can you see it? Views!

P.S.: There's a slight inaccuracy at 2:00—the Dolphin Head Nebula is not a supernova remnant, but the ejection of a pre-supernova shell.
