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?
On October 10-11, 2024, the aurora danced through skies across the globe. The storm was driven by a large, fast coronal mass ejection that had launched directly at the Earth about 38 hours before, and was heralded by a long-duration, very strong X1.8 class solar flare. During both the October and May 10-12 storms, the… Read More »Aurora World Tour—Again!

Science is one of many ways to get to know our Sun better, and the upcoming year will… Read More »Connecting Senses and Sensors with Solar Science
Every community of practice evolves its own vocabulary, and scientists and science communicators often rib themselves for how jargony STEM can be. In the late 1970’s, tech film narrator Bud Haggert created the affectionately cheeky “Turbo Encabulator“, using plausible but made-up jargon to make this classic engineering sketch incomprehensible. Engineers have delighted in recreating and… Read More »Small Words, Big Ideas: Up Goer Five
Since time immemorial, humanity has developed a deep and multifaceted relationship with our nearest star. While each culture expresses that bond in its own way, humans share millennia of solar observation. The Sun makes life on Earth possible, and its ever-changing nature affects our daily lives. What does the Sun mean to you? In Kiuġuyat:… Read More »Relationship With the Sun
While “discreet” means something that is a little bit secretive or unobtrusive, “discrete” auroras are distinct, bright, narrow bands—most commonly, photos of auroras are of this type. They typically have a definite lower border and can stretch high into the sky, like curtains, when viewed from the side. From below they are very narrow. They… Read More »What Is Discrete Aurora? (It’s Not Discreet!)
