For much of the past decade, Andrew McCarthy has been exploring the universe—albeit from his backyard in Arizona. Using telescopes with specialized filters, planetary cameras, and astro-specific software, he captures the happenings of universe in all ...
Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and migrate toward the star's equator in a butterfly-shape pattern before fading as the cycle resets.
New observations are helping scientists peer beneath the Sun’s surface, revealing where its magnetic activity may truly begin. Every 11 years, the Sun’s magnetic field reverses. As that cycle unfolds,
The powerful magnetic field belonging to the sun is generated far beneath the visible surface.
An Arizona-based astrophotographer has pulled off what may be an unprecedented feat in photography: capturing a skydiver in free fall perfectly aligned with the surface of the sun. Andrew McCarthy, who specializes in solar photography, coordinated with ...
The original version of this story appeared in Quanta Magazine. Our sun is the best-observed star in the entire universe. We see its light every day. For centuries, scientists have tracked the dark spots dappling its radiant face, while in recent decades ...
Sunburn and heat exhaustion aren’t the only reasons to avoid too much sunshine this summer: Going gray is another consideration. Hair strands, which grow out of glands called follicles, can't change color once they start growing (unless you dye them).
Players from 10 teams make up this list of the area's best.
Earth, sun, moon: three objects in space whose interactions have a pretty big impact on our lives. Earth orbits the sun once a year, and it rotates on its axis about once a day (depending on your definition of “rotate”). This gives us the night-day ...
Sun spots on your face can be reminders of a summer spent hiking, swimming or relaxing outdoors. But those marks are also signs of sun damage. And while there are ways to reduce the look of them, it's worth thinking about preventing sun spots too, experts say.
