The night is dark, and full of wonders. Some, however, are harder to see than others. One of them is so rare that if you’ve ever seen it, you’ve likely not realized what it is you’re seeing; a faint glow stretching up from the horizon on a moonless night.

After interviewing Mia Stålnacke, a master astrophotographer who chases the aurorae near the roof of the world, I began reminiscing about my time in New Zealand, where I spent the majority of my doctoral research days. That country, far from many things and still full of wide-open, empty space fringed by mountains, was certainly good at keeping things quite literally in the dark.

Light pollution was far less prominent than in most places that I’d lived, and on moonless nights in the Mackenzie Dark Sky Reserve on the South Island, you could see the galactic center of the Milky Way itself. I never saw a false dawn, though; at least, not to my knowledge. In order to understand what it is, though, we need to go a little bit back in time.

Since time immemorial – well, for many billions of years, anyway – there’s been dust in space. It’s incredibly fine, on the micro-to-nano-scale, which means you wouldn’t really be able to see individual grains without a microscope. It’s also everywhere, to an extent, and comes from a variety of sources.

You’ve got interstellar dust, which is created in the hearts of stars. When low mass stars swell up and blast off their outer layer, or when massive stars catastrophically obliterate themselves in a supernova explosion, their innards get scattered across the cosmos. When some heavier elements, often created in the brief moments during one of those latter blasts, combine with oxygen, you get a variety of additional, more exotic compounds.

Those compounds, rare for the universe compared to hydrogen and helium, but common for rocky worlds and objects, are what’s essentially interstellar dust. As the same suggests, it exists in the spaces between stars.

Interplanetary dust, on the other hand, is found in the space between planets – mostly within the inner Solar System. It comes from the asteroids and comets; it flies off smaller ones that rotate violently, or from the tail of comets as they approach stars, or from the collisions of asteroids within the asteroid belt.

Plenty of dust gathers together, forming the interplanetary dust cloud. It’s not a fixed cloud, neither: comets and rare asteroid collisions add to it all the time, while certain tiny, sunlight-bombarded particles give in to this radiation pressure and gradually begin to sail out of our cosmic backwater.

Microscopic though it may be, if enough conglomerates in the same space, we can actually see it, with the naked eye, from Earth’s surface. For that, we need to look to the ecliptic. This is the path in the sky that the Sun “follows” throughout the year. This isn’t a “real” path in the way Earth orbiting the Sun is, or our Solar System’s path around the galactic core is, but rather an apparent path. We orbit the Sun, but from our perspective, the Sun looks like it’s moving in the sky.

That’s the ecliptic. The zodiac, which extends 8 degrees north and south of the ecliptic, is a pretty useful zone in the sky that we’ve all gazed up into at some point. The paths of the Moon, as well as planets we can see with the naked eye – Venus, Mars, Jupiter and Saturn – appear in the zodiac.

There’s plenty of interplanetary dust hidden in there too. That dust is everywhere, as aforementioned, but it’s particularly concentrated along that line of sight. Sunlight from our very own star, reaching out to the dust, finds itself scattered and reflected, which causes this diffuse cloud to become ever so slightly luminous. That’s what we call the zodiacal light.

This isn’t easy to see. Per Space.com, the fuzzy, triangular-shaped light will be blocked out if you aren’t somewhere that’s entirely without light pollution. Anything other than a new moon will also camouflage the glow

If you’re in the Northern Hemisphere, and you wait until the hours of twilight, particularly after sunset in early spring, you might be luck enough to see this phantasmagorical effervescence. It’s sometimes referred to as a false dusk, according to EarthSky. You can see it before dawn too, particularly if you’re in the Southern Hemisphere during the late summer or early autumn – a false dawn.

It’s not just something beautiful to stare at if you manage to catch it in the act; it’s also a treasure trove of clues. That interplanetary dust, sourced from asteroids and comets the same age or older than our own world, can provide windows into the primitive geochemistry of an age lost to deep time. If only we had a way to vacuum it all up instead of just staring up at it, we’d be able to read the stories of those granular ghosts, rather than just wonder what they might say.

The night is dark, and filled with marvels. Some, nevertheless, are more difficult to see than others.

You have actually got interstellar dust, which is developed in the hearts of stars.
