The Bortle dark-sky scale (usually referred to as simply the Bortle scale) is a nine-level numeric scale that measures the night sky's brightness of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution. John E. Bortle created the scale and published it in the February 2001 edition of Sky & Telescope magazine to help amateur astronomers evaluate the darkness of an observing site, and secondarily, to compare the darkness of observing sites. The scale ranges from Class 1, the darkest skies available on Earth, through to Class 9, inner-city skies. It gives several criteria for each level beyond naked-eye limiting magnitude (NELM).[1] The accuracy and utility of the scale have been questioned in recent research.[2] The table below summarizes Bortle's descriptions of the classes. For some classes, there can be very drastic differences from one class to the next, e.g, Bortle 4 to 5.

Can you feel the void between us

Nothing there but light, yet it seems like the weight of the world

Keeping us here in the dark

If I allow our blessings define us

Bearing the scars of our loss like it's all we deserve

When passions we hold will depart

I got nothing to call a solution

Not a penny to my name, just riding the motion

Yet like a child I still reach for the stars

But if this darkened hole is my conclusion

And the mother of pearl world is just a notion

I lose for playing out my part in this farce


Rewind, I wanna go it again, light up the dark, halo on the side

So I'll know it will not leave me wanting, I see my heart, waving me bye-bye

Rewind, I wanna go it again, light up the dark, halo on the side


Rewind, I wanna go it again, light up the dark, halo on the side

So I'll know it will not leave me wanting, like my love, kissing me good bye

Rewind, I wanna go it again, light up the dark, halo on the side


Rewind, I wanna go it again, light up the dark, halo on the side

So I'll know it will not leave me wanting, I see my heart, waving me bye-bye

Rewind, I wanna go it again, light up the dark, halo on the side

So I'll know it will not leave me wanting, like my love, kissing me good bye

Rewind, I wanna go it again, light up the dark, halo on the side


(Uh huh,) Yeah, don't you say that I didn't, didn't

Give you a chance, just didn't listen

Only wanted out, but you just kept that garbage talk, so no blessings

Y'all looking present, I'm already futuristic-cruising

Satisfaction killed me a bit, but curiosity brings me back in grooving

Don't wanna follow order, I 'ought to restore that

Told her crossing the border, next corner posing for reporters

Next level explorer with my crew, supporters

Still conquesting forward with my crew


Like the shining stars lights the path whenever it's dark

You keep on blinking at me

You never turn away from me, in this vast gloomy night sky

Light the fire up in the night

The journey that we travel for uprise

No matter where we go, we will not stop the shining forever


The views that I see is not flat, more like panorama

More to it, more of a drama, going gorillas, bananas

I just wanna have a lotta fun in life

Surviving the riding, I'm driving

No idling, battling, and I keep it dazzle


Yeah, don't you say that I didn't, didn't

Give you a chance, just didn't listen

Only wanted out, but you just kept that garbage talk, so no blessings

Y'all looking present, I'm already futuristic-cruising

Satisfaction killed me a bit, but curiosity brings me back in grooving

Don't wanna follow order, I 'ought to restore that

Told her crossing the border, next corner posing for reporters

Next level explorer with my crew, supporters

Still conquesting forward with my crew


Like the shining stars lights the path whenever it's dark

You keep on blinking at me

You never turn away from me, in this vast gloomy night sky

Light the fire up in the night

The journey that we travel for uprise

No matter where we go, we will not stop the shining forever


The views that I see is not flat, more like panorama

More to it, more of a drama, going gorillas, bananas

I just wanna have a lotta fun in life

Surviving the riding, I'm driving

No idling, battling, and I keep it dazzle

"Shooting stars" and "falling stars" are both names that describe meteors -- streaks of light across the night sky caused by small bits of interplanetary rock and debris called meteoroids vaporizing high in Earth's upper atmosphere. Traveling at tens of thousands of miles an hour, meteoroids quickly ignite from the searing friction with the atmosphere, 30 to 80 miles above the ground. Almost all are destroyed in this process; the rare few that survive and hit the ground are known as meteorites.

After you've escaped the city glow, find a dark, secluded spot where oncoming car headlights will not periodically ruin your sensitive night vision. Look for state or city parks or other safe, dark sites.

Treat meteor watching like you would the 4th of July fireworks. Pack comfortable chairs, bug spray, food and drinks, blankets, plus a red-filtered flashlight for reading maps and charts without ruining your night vision. Binoculars are not necessary. Your eyes will do just fine.

Autumn and winter seasons, with their long periods of darkness and the frequency of clear nights, are probably the best time of the year to experience the auroral displays. Nights need to be cold and the sky clear of clouds, with limited light pollution and increased solar activity. Staying up until the wee hours of the morning may also help.

Aurorae come in all colours, shapes and patterns, setting the night sky alive with rainbows of light. The variations in colour are due to the type of gas particles that are colliding, from yellowish-greens, blues and purples, to fiery reds and oranges. The playful streaks that snake across the night sky evolve and change constantly, and can last minutes or merely seconds. One thing is for certain: the end result is always truly spectacular.

To reach Point Dume, head to the southern end of Big Dume Beach and locate the trail entrance toward the back of the bluff before climbing up its switchbacks to the rocky summit. This lookout also offers views of stunning Pacific sunsets, and after darkness sets in, it reveals a long, glittering necklace of city lights uncoiling leftward along the Southern California coast.


Although Topanga State Park is technically part of Los Angeles, most of its 11,500 acres remain well-insulated from the adjacent sea of urban lights. The gates close at sunset, but star chasers can still park at the entrance and night-hike to scout out a personal auditorium of the sky. Tilt your head skyward (especially after midnight) to scope out shooting stars, which appear in droves during certain times of the year.


With shrub-lined hills that buffer ambient light pollution and plenty of open grassy meadows, Malibu Creek State Park abounds with spectacular 360-degree views of the celestial plane. After a pink and gold Santa Monica Mountains sunset, stick around to watch the night deepen around the surrounding wilderness.

Originally, the terms "morning star" and "evening star" applied only to the brightest planet of all, Venus. It is far more dazzling than any of the actual stars in the sky and does not appear to twinkle. Instead, it glows with a steady, silvery light. The fact that Venus was a wandering star soon became obvious to ancient skywatchers, who noticed its shifting back and forth from the early hours of the eastern morning sky to the western sky in the early evening. Nicolas Camille Flammarion, a noted French astronomer in the late 19th and early 20th century, referred to Venus as "The Shepherd's Star." I myself like to refer to Venus as the "night light of the sky." So, one can readily understand the origin of the terms evening and "morning star" if we only considered Venus.

Of course, Venus is not the only wandering "star" in the sky; there are four others that are also visible to the unaided eye (five, if you include Uranus, which is barely perceptible without any optical aid on dark, clear nights). The difference is that, with the possible exception of Jupiter and, on rare occasions, Mars, none of the others stands out in the same manner as Venus. Nonetheless, somewhere in the distant past, "morning star" and "evening star" became plural in order to account for the four other planets.

In order to understand why \u201cRed sky at night, sailor\u2019s delight. Red sky in morning, sailor\u2019s warning\u201d can predict the weather, we must understand more about weather and the colors in the sky.

When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow. ff782bc1db
