May the 4th be with you: the Twin Suns of Tatooine
One of my recent blogs crushed the dreams of many Star Wars fans by debunking the close proximity of asteroids within an asteroid field in The Empire Strikes Back. That is why, in the spirit of Star Wars Day, I will be sharing an aspect of the films that Star Wars ended up getting correct:Continue reading “May the 4th be with you: the Twin Suns of Tatooine” Continue reading
ExploreSol
It might surprise you to know that the sun is over 90 million miles away from us! That’s right: something that far away is able to provide us with life-saving light and warmth. A process called nuclear fusion is responsible for the sun’s tremendous heat and brilliant shine. Though it may look different from otherContinue reading “ExploreSol” Continue reading
The Carrington Event
When Dr. G first mentioned the Carrington Event in class, I was equally interested and terrified. The idea that a solar coronal mass ejection could happen today and wreak havoc on electrical grids leading to blackouts and an inability to communicate has now been added to my list of fears (much in the same veinContinue reading “The Carrington Event” Continue reading
What threat do Coronal Mass Ejections Pose to Us?
As discussed in class, one of the side effects of the Sun’s shifting magnetic field is that, occasionally, it arranges in an inconvenient fashion that causes the Sun’s plasma to explode aggressively outward. Thankfully, whenever that comes towards Earth, we are protected from any health effects thanks to our atmosphere. But as Professor Grundstrom mentioned,Continue reading “What threat do Coronal Mass Ejections Pose to Us?” Continue reading
Solar Flares
The sun is massive. And despite it being so far away, I can’t help but wonder if activity on the sun could possibly effect life on Earth. Enter: solar flares. According to NASA, solar flares are “great bursts of electromagnetic energy and particles that can sometimes stream from the Sun”. Occasionally, solar maximums occur whichContinue reading “Solar Flares” Continue reading
A History of Observing the Sun
Kevin Durant, a two-time NBA champion, once tweeted: “I’m wondering how do these people kno what’s goin on on the the sun.. ain’t nobody ever been.” Like his tweet from 2010, I too wondered how humans have been able to study the Sun’s surface and what discoveries have been made to determine the surface’s characteristics.Continue reading “A History of Observing the Sun” Continue reading
The Next Ice Age?
As we all know, the sun is an incredibly vital part of our daily lives and is the, “constant force that is keeping our planets in orbit, providing Earth with just the right amount of light and warmth for life…” and even governs our daily schedules in which we have created the concept of timeContinue reading “The Next Ice Age?” Continue reading
No sunspots on the Sun?
Have you ever seen pictures of the Sun and noticed that it has dark spots on its surface? These sunspots are cooler than the other regions on the Sun, but they also represent the beginning of new solar cycles. In fact, some signs point to the next cycle, Cycle 25, having a much smaller numberContinue reading “No sunspots on the Sun?” Continue reading

Aurora Borealis
Aurora borealis, or the “Northern lights,” as it is often called, is the result of our Earth’s magnetosphere deflecting harmful particles from the Sun from the Earth. They can best be seen from the Arctic Circle (Canada, Iceland, Finland, etc.). Every aurora in the solar system originates from the Sun. Periodically, the Sun has stormsContinue reading “Aurora Borealis” Continue reading

The Danger of a Coronal Mass Ejection
A Coronal Mass Ejection (CME) is essentially a powerful expulsion of plasma and accompanying magnetic field from the solar corona, or the sort of aura of plasma that surrounds our Sun. While they have an extremely cool name, and seem pretty neat, they could actually have a pretty significant impact on humanity. The Sun has an incrediblyContinue reading “The Danger of a Coronal Mass Ejection” Continue reading
