Active areas at the sun

Active areas on the Sun are regions with extremely strong magnetic fields, up to 1,000 times stronger than the Sun's average magnetic field. It is from these areas that solar storms, solar flares and coronal mass ejections (CMEs) most often emanate.

Sunspots: Dark, cooler areas in the photosphere where the magnetic field is extra concentrated. The number of sunspots follows a cycle of about 11 years. Plagues (bright areas): Bright, hot regions in the chromosphere surrounding sunspots. Solar flares: Sudden and intense energy discharges that send out radiation. Coronal mass ejections (CMEs): Huge clouds of plasma and magnetic fields that are thrown out from the Sun.

AR4425

AR4425 (also known as 14425) is an active sunspot region currently located on the Earth-facing side of the Sun in late April and early May 2026. Here is the latest status of the region: Magnetic classification: It has recently been downgraded to a beta (β) configuration after losing its more complex "delta" structure, meaning its potential for powerful solar storms has decreased somewhat.

In recent days, AR4425 has been one of the more prominent regions, contributing to several C-class flares as well as occasional M-class (moderate) flares, including an M2.2 on April 26.

The region is currently moving across the northwestern quadrant of the Sun's disk. Although it has shown signs of decreasing complexity, it is still closely monitored by space weather services such as NOAA as it moves toward the edge of the Sun.

Center of our galaxy

The center of our galaxy rises from the ocean late at night off the east coast of Sweden. The center of the Milky Way is the dense core of the galaxy, located about 25,000–28,000 light-years from Earth in the constellation Sagittarius. At its absolute center is the supermassive black hole Sagittarius A* (not visible in these photos, still under the sealine), which weighs about 4 million solar masses. The area is hidden behind thick space dust and is characterized by an extreme density of stars.
