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]
The sun's activity is expected to continue to increase until it reaches peak activity levels, which scientists call solar maximum. "Current predictions suggest solar maximum will occur in the ...
NASA says the sun is in the highly active "maximum phase" of its 11-year solar cycle.. That means there will probably be big solar storms bringing beautiful aurora in the next year or so. Solar ...
Institution: NASA; New Horizons. Mission: the first spacecraft to study Pluto up close, and ultimately the Kuiper Belt. It was the fastest spacecraft when leaving Earth and will be the fifth probe to leave the Solar System. Launched: 19 January 2006; Destination: Pluto and Charon; Arrival: 14 July 2015; Left Charon: 14 July 2015; Institution ...
A powerful solar flare has been hurled out of the Sun, and could cause disruption on Earth. The flare comes amid increasing solar activity that has brought a run of intense space weather in recent ...
Reconstruction of solar activity over 11,400 years. Sunspot numbers over the past 11,400 years have been reconstructed using carbon-14 and beryllium-10 isotope ratios. [10] The level of solar activity beginning in the 1940s is exceptional – the last period of similar magnitude occurred around 9,000 years ago (during the warm Boreal period).
The sun will reach solar maximum, or a peak in activity across its 11-year cycle, about a year sooner than originally predicted. Auroras, solar flares and space weather are all expected to increase.
NASA Solar Cycle 24 Sunspot Number Prediction. Solar cycle 24 is the most recently completed solar cycle, the 24th since 1755, when extensive recording of solar sunspot activity began. [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 ...
