Cosmology & Astronomy
Solar dynamo irregularity linked to planetary forcing (arXiv, Feb 2026) William A. Gardner and Antonio Napolitano report that two of the Sun's well-known irregular periodicities — the roughly 27-day plasma rotation and the roughly 11-year magnetic polarity reversal — share a common underlying pattern in how their timing drifts. As the abstract puts it, the pattern "proceeds from zero delay to maximum delay, back to zero delay, then to maximum advance." The authors connect this to recent (November 2025) work proposing that planetary motions help drive the solar dynamo. Source: https://arxiv.org/pdf/2602.18625 Replot candidate: the delay/advance cycle they describe (zero → max delay → zero → max advance → zero) could be redrawn as an original phase diagram if you want a visual for the post.
Forecasting sunspot cycles 25 and 26 with 276 years of data (Scientific Reports, Jan 2026) Abdel Rahman and Badawy applied the Facebook Prophet forecasting model to sunspot counts stretching back to 1749, projecting the tail end of Solar Cycle 25 and the entirety of Solar Cycle 26 (through 2036). Their model puts Cycle 26's peak around mid-2034 with a smoothed sunspot number near 118. Source: https://www.nature.com/articles/s41598-025-33819-5 Replot candidate: yes — the projected Cycle 25/26 sunspot curve could be redrawn as an original line chart from the stated peak values and known cycle timing.
Six-planet parade, total solar eclipse, and Perseid peak converge on Aug 12, 2026 Multiple stargazing outlets note that this single date stacks three separate celestial cycles: a six-planet alignment (Jupiter, Mercury, Mars, Uranus, Saturn, Neptune), a total solar eclipse visible from parts of Europe, and the Perseid meteor shower peak.

Astrology
Same August 12 convergence, flagged for its rarity rather than routine content Worth cross-posting here per the "genuinely newsworthy" exception — three independent celestial cycles (planetary, lunar/solar, meteoric) lining up on one calendar date is an unusual coincidence of periods worth noting, distinct from routine horoscope material.

Climate & Weather
ENSO cycles are shortening under warming — "frequency entrainment" (Nature Communications, Jul 2026) Iwakiri and Kug used multi-model climate simulations (CMIP6) to show that as the El Niño–Southern Oscillation cycle shortens under future warming, that shift in rhythm propagates outward to other tropical climate modes and regions via teleconnections — a phenomenon they name "ENSO frequency entrainment." Source: https://www.nature.com/articles/s41467-026-74381-6 Replot candidate: possible, if the paper's supplementary data on period-shift magnitude is accessible — otherwise a schematic of the teleconnection concept could be built instead.
Three dominant oscillation modes in Mediterranean precipitation (Theoretical and Applied Climatology, Jun 2026) Kalimeris, Founda, and Hatzaki analyzed ERA5 reanalysis precipitation data for the greater Mediterranean (1950–2023) and identified three recurring cycles — around 65 years, 35–50 years, and 4–8 years — as the main drivers of variation in precipitation height and wet-day counts. Source: https://www.researchgate.net/publication/243786163_An_Oscillation_in_the_global_climate_system_of_period_65-70_years Replot candidate: yes — the three stated period bands (65yr / 35-50yr / 4-8yr) and their relative contribution would make a clean original bar or spectrum chart.
Bitcoin & Cryptocurrency
Spectral analysis finds Bitcoin has more than one cycle (FractalCycles, Jan 2026) Using Goertzel-algorithm spectral analysis on Bitcoin's price history, FractalCycles found the well-known four-year halving cycle is real but not alone — they also detect short multi-week cycles tied to derivatives funding-rate dynamics, multi-month intermediate cycles, and a longer structural cycle running independently of the halving calendar at roughly 9.5 months. They note on-chain activity data shows similar periods, which they treat as independent cross-validation of the price-based finding. Source: https://fractalcycles.com/markets/bitcoin-beyond-halving Replot candidate: yes — the set of detected periods (multi-week / ~9.5-month / ~4-year) would work well as an original spectral-style bar chart.
Where the ~4-year cycle sits in 2026 (FractalCycles, Feb 2026) A companion piece notes the dominant Bitcoin cycle clusters near 1,400 days (about four years), while 60–120 day cycles are described as more useful for shorter-term timing.

Kondratiev long wave possibly bottoming in 2026 (KuCoin, Mar 2026) A market-analysis piece revisits the Kondratiev wave — the roughly 40–60 year economic supercycle tied to major technology shifts — and argues 2024–2026 may mark its bottoming-out phase, based on alignment with historical stock, commodity, and credit-cycle timing. Source: https://www.kucoin.com/blog/kondratiev-wave-2026 Note: this is crypto-investment-toned rather than academic; flagging in case you'd rather source the Kondratiev angle from a more scholarly reference instead.
Stock Markets
Diamond top pattern flagged in S&P 500 technicals (Cycles Edge, Jul 2026) A cycles-focused market newsletter describes technical signs — a turning 20-day moving average, rising volatility, and a forming Diamond chart pattern — often associated with market tops, alongside relative-strength divergences across major US indices. Source: https://cyclesedge.substack.com/p/july-and-august-2026-cycle-forecasts Note: borderline fit — trading-newsletter framing rather than a stated measured period; include only if you're comfortable with that tone for the forum.

On graphics
None of the above images/charts should be lifted directly from the source pages (copyright). Three items are flagged above as good replot candidates — meaning the source states the underlying numbers (specific periods, peak values, or period bands) clearly enough that an original chart could be built from those figures rather than copied. Let me know which of those you'd like turned into an actual chart, and I'll build it.
