Cambridge University ...
While researching aerodynamics of bumblebees.
I found a bunch of amazing attributes about the honey bee,
After I needed to relocate a hive that had taken up residence
in one of My exterior walls !
The drywall inside was warm from the amount bees and hive size
Alas I digress.

It is said that it takes approximately 37,000 years to travel one light year.
According to NASA the Horsehead Nebula is 5 light years tall. Let's say you traveled those 5 light years, it would take you approximately 185,000 years to travel across. Starting at other points though, traveling across would take less time (it's not as wide as it is tall, of course). It will still take over 100,000 years to get across (if we use the measurement of it taking 37,000 years to travel a light year).
Note: Different sources give different measurements of the Horsehead Nebula.

Folks, this is how big these nebulae are... consider this.
The Orion Nebula, e.g., is about 10 to 25 light-years across. This is about 60 to 150 trillion miles. That nebula would encompass our sun, Sirius (8.7 LY away), Procyon (11.45 LY away), Altair (16.7 LY), almost all the way to Vega (~27 LY away).
To give you an idea of how far away this thing is, this ~25 trillion LY-wide cloud is a small blueish smudge in the winter sky. 25 trillion LY wide, at ~1,500 LY away, looks like a smudge slightly larger than the stars comprising the constellation. (The above-mentioned stars would fit into that smudge.)
And, you must bear in mind that this thing's a stellar "neighbor". Its distance from us is only about 1.5% the width of our galaxy.
The Andromeda galaxy's about 2 million LY away. That's about 20 Milky Way galaxy diameters. And, that's just a galactic neighbor.
There is no Other.

The enzyme that produces bioluminescence in fireflies, which are neither bugs nor flies but are actually beetles, is called luciferase.
And there is a femme fatale species of firefly that frequents the fireflies' singles bar' happy hour and mimics the flash of males in order to lure them within chomping distance.

A group of engineering students from Purdue University reported that its licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. Twenty of the group's volunteers assumed the licking challenge-unassisted by machinery-and averaged 252 licks each to the center.
