Magnetism and the Solar Cycle Now that we have discussed the Sun''s activity cycle, you might be asking, "Why does the Sun change in such a regular way?" Astronomers now understand that it is the Sun''s changing magnetic field that drives solar activity. The ...
However, the currently used data sets give controversial results on the solar cycle length during the Maunder Minimum, which has been suggested to be a normal 11-year (Beer et al., 1998; Poluianov et al., 2014; Schlamminger, 1990; Schröder, 199220041992).

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. It is expected to continue until about 2030.
Solar Cycle 25 has begun. During a media event on Tuesday, experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) discussed …
Oakland, CA / March 15 – SOLARCYCLE®, a tech-driven recycling company focused on producing sustainable materials at scale for the solar industry, today announced that it has raised $30M in Series A funding, bringing the company''s total funding to $37M since its inception a year ago.
The Solar Cycle 25 Prediction Panel announced solar minimum occurred in December 2019, marking the transition into a new solar cycle. In a press event, …
The solar cycle is important for determining the lifetime of satellites in low-Earth orbit, as the drag on the satellites correlates with the solar cycle, especially as represented by …
In particular Space Weather describes the phenomena that impact systems and technologies in orbit and on Earth. Space weather can occur anywhere from the surface of the sun to the surface of Earth. As a space weather …

For a more massive protostar, the core temperature will eventually reach 10 million kelvin, initiating the proton-proton chain reaction and allowing hydrogen to fuse, first to deuterium and then to helium. In stars of slightly over 1 M (2.0×10 30 kg), the carbon–nitrogen–oxygen fusion reaction (CNO cycle) contributes a large portion of the energy generation.
Among them, large-scale Concentrated Solar Power plants occupy a relevant place. However, medium-size plants, between 100 KW and 10 MW, have not been evaluated as intensively, resulting in a lack of knowledge in …
The solar cycle describes an approximately 11-year cycle of solar activity driven by the sun ''s magnetic field and indicated by the frequency and intensity of …
To align the lunar and solar calendars, a 33-year cycle was created. After 33 years, the moon has orbited an additional year (363 days), allowing it to catch up with the earth''s orbit. The calculation 365 …
The Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and the National Oceanic and Atmospheric Administration (NOAA), announced that solar minimum occurred in December 2019, marking the start of Solar Cycle 25. Since then, the Sun''s activity has been steadily increasing as it approaches …
Here''s what causes the sun''s 11-year cycle of activity and what it means for us on Earth. Over two weeks in 2017, NASA''s Solar Dynamics Observatory watched this storm on the sun''s surface. The storm appears to …
Solar cycle, period of about 11 years in which fluctuations in the number and size of sunspots and solar prominences are repeated. Solar cycle 25 began in 2019 and will reach maximum in 2025, but that …

Solar Cycle 25 has begun. The Solar Cycle 25 Prediction Panel announced solar minimum occurred in December 2019, marking the transition into a new solar cycle. In a press event, experts from the panel, NASA, and NOAA discussed the analysis and Solar Cycle 25 prediction, and how the rise to the next solar maximum and …
On Sept. 15, scientists announced that the Sun has entered a new cycle, marked by solar minimum in December 2019. Read on to meet a few people whose everyday I lead research on geomagnetic disturbances at the Electric Power Research Institute. We work ...

Solar activity has a cyclic nature with the ≈11-year Schwabe cycle dominating its variability on the interannual timescale. However, solar cycles are significantly modulated in length, shape and magnitude, from near-spotless grand minima to very active grand maxima. The ≈400-year-long direct sunspot-number series is …
Solar cycles are nearly periodic 11-year changes in the Sun''s activity that are based on the number of sunspots present on the Sun''s surface. The first solar cycle conventionally is said to have started in 1755. The source data are the revised International Sunspot ...
