by Tanya Melnik and Laura Edson The aurora follows a “life cycle” called a substorm. We know the feeling of waiting for the most dynamic part of the substorm to light the sky with green and red ribbons, but sometimes it seems to take forever. In this post we’ll go over a couple of reasons… Read More »Staying cool with aurora science
While the Sun appears constant, in terms of heliophysics the Sun varies naturally and goes through significant daily variations. With solar maximum in the recent past, a common question about auroras is: are they caused by sunspots? As with a lot of aurora science, the answer is somewhat complicated, and includes several phenomena that are… Read More »How are sunspots related to auroras?
by Laura Edson, MAT in Museum Education A question we have received more and more at Aurorasaurus is, “Do you have any suggestions for presenting auroras to the public?” The aurora is a really fun topic to share; it is instantly engaging and technically challenging, artistically beautiful and scientifically fascinating. But it can also be… Read More »Presenting Auroras: Three Lessons from Museum Education
With contributions from Dr. Andréa Hughes The short answer is yes, but they are different from those on Earth. When we think about the aurora, we often imagine beautiful green and red lights that ring the night skies around the north and south poles, with the most dramatic displays in the hours around midnight. This… Read More »Are there auroras on Mars?
What an incredible storm we had November 11-13, 2025! We have been so excited to see the beautiful pictures and thrilling sightings you had from all over the world! We have an amazing community, and we are so grateful for every report. We are also often approached by aurora chasers who ask, “What are you… Read More »A wish list for aurora reports
Auroras are made when particles bump into atoms and molecules in the Earth’s upper atmosphere, giving them energy. The atoms and molecules then give off that energy as light in specific colors: red, green, blue, and pink. But why on rare occasions do auroras seem to have yellow, cyan, or purple in them? In this… Read More »Why do auroras sometimes look yellow?
When chasing aurora, have you ever felt your mindset shift? You might think of it as getting into the zone, or into the groove of the chase. “There’s this focus that, once it becomes intense, leads to a sense of ecstasy, a sense of clarity: you know exactly what you want to do from one… Read More »Getting into Flow in Participatory Science
Have you ever wondered how scientists get data to learn about aurora? One way is by sending scientific “sounding rockets” into the Earth’s upper atmosphere to take measurements. One location from which these instruments are launched is Poker Flat Research Range in Fairbanks, Alaska, part of the University of Alaska Fairbanks Geophysical Institute. Nine undergraduate… Read More »Science in Action: Visiting Poker Flat Research Range
With graduation season underway, we’re reflecting on the insights and experiences we would share with this year’s newly minted professionals. We’re finding ourselves inspired by the nine undergraduate and graduate students who attended the Eclipses to Aurora: Winter Field School at the University of Alaska Fairbanks. How did this experience cause them to reflect on… Read More »Poetic Wisdom From Winter Field School
Guest post by Vincent Ledvina, Laura Edson With thanks to Valerie Svaldi for additional input One of the terms you’ll often aurora chasers and scientists use is “substorm.” You might hear it referring to the best parts of an aurora chase, or as something to patiently wait for. But what does it mean, and where… Read More »What is an auroral substorm?
