Sunspots are the most striking phenomenon of the solar magnetic field. After the invention of the telescope early in the 17th ...

When sunspots erupt at nearly the same time, it could be something known as "sympathetic solar flares." A double eruption ...

Sunspots are cooler, planet-size regions of strong magnetic fields on the surface of the sun. Explore sunspots in more detail with our comprehensive guide.

Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar ...

After witnessing the array of Northern Lights as far south as Colorado, we discuss how Coronal Mass Ejections (CME) are ...

Two spacecraft are currently directly observing the Sun: NASA's Parker Solar Probe (which will eventually approach to just 5% of the Earth-Sun distance), and ESA's Solar Orbiter, which is en route to ...

Experts have advised people to monitor reliable sources like NASA and NOAA for updates on solar activity and space weather.

Most sunspots are a few thousand kilometers across and too small to see without aid from binoculars or a telescope. But some grow to enormous size, tens of thousands of kilometers across or more.

Sunspots have a cooler temperature of 8,000 degrees. Murray says if you could take the darker color of a sunspot and bring it to Earth, it would still be way too bright to look at.

Sunspots are indicative of magnetic disturbances in our star, they appear as dark patches on the surface of the sun and can be as big as Earth. Their presence is a clue to where the sun is in its ...

However, these three sunspots have a 40 percent chance of triggering dangerous M-class solar flares, which are medium-sized and can cause brief radio blackouts around Earth’s polar regions.

Before this summer, the number of sunspots have been below the average. As far as coronal mass ejections from the sun, the data shows 31 storms impacted Earth last year. This year, Earth is ...
