It's twilight.

Twilight.

THE TWILIGHT ZONE.

But drenched in vanilla twilight

Auroras Underfoot.

Its southern counterpart, the aurora australis (or the southern lights), has features that are almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone.

I have read the Twilight tetralogy.

I have read the Twilight tetralogy.

THAT ARE A PART OF THE TWILIGHT ZONE.

And you'll see that it leads with a shifting star field, and there's an Aurora Borealis in the background, kind of morphing with color.

Auroras also occur on other planets.

We fly right over them.

I've never seen the aurora borealis.

Sometimes in the twilight I alternately lost and recovered sight of one sitting motionless under my window.

Auroras are caused by solar activity.

I thought we were gonna enjoy the waning twilight together.

Other processes are also involved in the aurora, and much remains to be learned.

This left the room in a twilight. This done, he returned with an easier air to the table and his meal.

Richard Pyle dives the reef's Twilight Zone

Protons are also associated with auroras, both discrete and diffuse.

For example, the Gunditjmara people of western Victoria called auroras Puae buae , meaning ashes , while the Gunai people of eastern Victoria perceived auroras as bushfires in the spirit world.

Eight publishers competed for the rights to publish Twilight in a 2003 auction.

The northern and southern lights, also known as the aurora Borealis and aurora Australis, respectively, occur when high energy particles from the Sun collide with neutral atoms in our atmosphere.

Then comes that warm afterglow that energizes and exudes goodwill.

In Medieval Europe, the auroras were commonly believed to be a sign from God.

The aurora can be seen best at this time, which is called magnetic midnight.

It is not disorienting to see auroras underfoot, he says.

Indeed, more auroras are in the offing.

Scientists around the world are interested in phenomena related to Sun Earth interactions, in particular the aurora.

I want this day to be ours, just you and I... alone in the waning twilight.

Early evidence for a geomagnetic connection comes from the statistics of auroral observations.

The collection of these interactions is what creates the northern and southern lights.

From this book anyone can learn about the aurora borealis or the Eskimos

Occasionally the resulting modification of the Earth's magnetic field can be so strong that it produces auroras visible at middle latitudes, on field lines much closer to the equator than those of the auroral zone.

And you'll see that it leads with a shifting star field, and there's an Aurora Borealis in the background, kind of morphing with color. The color of the Aurora Borealis can be controlled using this single bar of color at the bottom, and we'll put it down here to red.

Similar to the Earth's aurora, they are also visible close to the planets magnetic poles.

Predictive techniques are also used, to indicate the extent of the display, a highly useful tool for aurora hunters.

The protons and electrons creating the northern lights depart from the Sun's corona.

Do you know that at the top of the world, twilight is six months long?

We can actually fly into the auroras, says astronaut

Sometimes you feel like you can reach out and touch them.

This is still speculative, but Comet ISON could provide the seeds for a noctilucent display.

An aurora was also detected on Mars, on 14 August 2004, by the SPICAM instrument aboard Mars Express.

And probably the best part of this piece is at dusk and dawn when the twilight wedge has fallen and the ground's dark, but there's still the light above, bright above.

Longtime sky watchers say it is the greatest show on Earth.
