Sunspots and Space Storms
Today’s astrobite dives into the differences between space weather and space climate and how sunspots affect both processes.
Old, New, Cyclic, and Ultra-Blue: Visualizing the Last 400 Years of Solar Activity
Historic observations of sunspot variability have improved our understanding of the solar cycle tremendously, but recent reanalyses of these data has yielded a conflicted view on solar variability within the past few centuries. Today’s paper shows how we can both better visualize existing historic data and where we can go next in understanding the long-term variability of our closest star.
Vary, Vary, Little Star…Or Don’t, If You’re the Sun
Why is our Sun so anomalously stable in brightness compared to other stars? The authors of today’s paper decided to run some simulations to find out.
What Are Starspots Like on Sun-like Stars?
There are a lot of Sun-like stars in the universe. Are they as identical as the name suggests, or are there important differences between them?
Two Solar Tornadoes Observed with IRIS
Today’s undergraduate research post features a student who analyzed the motion of tornadoes on the Sun’s surface using spectroscopy. Read on to find out more!
Building Butterflies from Starlight
Even though the Sun and other stars are constantly shining down on us, there’s a lot about them that we still don’t understand.
In today’s astrobite, we explore a new approach for learning about one stellar mystery in particular: the magnetic fields of Sun-like stars.
