Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. [2] It is expected to continue until about 2030. [3] [4]
Solar maximum is the regular period of greatest solar activity during the Sun's 11-year solar cycle. During solar maximum, large numbers of sunspots appear, and the solar irradiance output grows by about 0.07%. [2] On average, the solar cycle takes about 11 years to go from one solar maximum to the next, with duration observed varying from 9 to ...
[1] [2] It began in December 2008 with a minimum smoothed sunspot number of 2.2, [3] [failed verification] and ended in December 2019. [4] Activity was minimal until early 2010. [ 5 ] [ 6 ] It reached its maximum in April 2014 with a 23 months smoothed sunspot number of 81.8. [ 7 ]
In 2024, the sun enters its solar maximum—birds don't know what's about to hit them. Space weather may seriously send their internal compasses into disarray. In 2024, the sun enters its solar ...

The solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25.
More people currently live in the path of totality compared to the last eclipse . An estimated 31.6 million people live in the path of totality for 2024’s solar eclipse, compared to 12 million ...
Helios-A and Helios-B (after launch renamed Helios 1 and Helios 2) are a pair of probes that were launched into heliocentric orbit to study solar processes. As a joint venture between German Aerospace Center (DLR) and NASA, the probes were launched from Cape Canaveral Air Force Station, Florida, on December 10, 1974, and January 15, 1976, respectively.
