The reader is invited to learn more about how auroras are created, the folklore surrounding them as well as the story of why Swedish Lapland is hailed as the best place on Earth to see the auroras. And once you are inspired, Peter offers you his tips on how to best capture your own...
Physicists led by the University of Iowa report definitive evidence that auroras that light up the sky in the high latitudes are caused by electrons accelerated by a powerful electromagnetic force called Alfven waves.

It was this solar storm that created the widely seen auroras, and many amateur astronomers and even regular people without any particular astronomical knowledge were able to capture beautiful images because of developing camera technology. “Cameras — even standard cell phone cameras — are much more...
STEVE is a streak of purplish light in the night sky that's similar to an aurora. In fact, STEVE has only ever been observed in conjunction with an aurora. That's because both phenomena are thought to be created by the samespace weatherevents, according to theEuropean Space Agency (ESA)...
Auroras are created when charged particles shot out by the sun slam into Earth's magnetic field, warping it. Some of those charged particles make it through the magnetic field, slamming into the upper atmosphere and interacting with neutral particles, creating the glow that we see as the northe...
We are currently about 4.5 billion years into our sun's main sequence days — or approximately halfway through its life. What happens when that hydrogen is all used up? Things start to get a little crazy, to put it mildly. Without the outward pressure of the energy created by fusing ...
Low light, cold temperatures and the unpredictable nature of auroras make them a rather tricky subject. That's why we have created a "Where and how to photograph the aurora" guide that includes the best techniques and camera settings to help you get started. Speaking from experience, it is ...
Even if you can't travel to one of these areas, you should still go out and look up anyway. When conditions are right,auroras can be visible from over 600 miles away. What causes auroras? Tweet may have been deleted While auroras can also be caused bysolar flares, we can thankcoronal...
This picture was created by stacking 5 x 30-second exposures in Photoshop. The next time you are out taking pictures of the night sky or the Milky Way, be sure to take a series of 30-second images rather than just one or two. Aim to capture about 10-20 pictures to realize the benef...
Are there southern circumpolar stars? How are magnetic fields created for terrestrial planets? What does the Earth's magnetic field look like? When did Polaris become the North Star? Which of the following correctly describes the meridian in the sky? a. a half-circle extending from your horizon...
