There’s a Hidden Signal in the Sun, Study Suggests
A recent study has revealed a hidden pattern of solar magnetic activity beneath the Sun's surface. Researchers analyzed 40 years of helioseismic data and found that this internal 'biorhythm' indicates changes in solar activity that traditional methods could not detect. The findings suggest a long-term change in the Sun's magnetic activity, which may impact space weather predictions.
- ▪Astronomers discovered a previously unknown pattern of solar magnetic activity just below the Sun's surface.
- ▪The study analyzed 40 years of helioseismic data, revealing a connection between internal solar oscillations and surface activity.
- ▪Solar cycle 25 has exceeded initial predictions, indicating a structural reorganization of magnetic activity beneath the Sun.

For all we’re learning about the distant cosmos, there’s still much we don’t understand about things much closer to us, like the Sun. It’s difficult to investigate something as big and hot as the Sun up close, so astronomers have to use other means, like tapping into the hidden sound waves from deep inside the star.cnx.cmd.push(function(){cnx({"playerId":"92b7b46b-43ed-4e0e-b21b-2c999302d9d7","settings":{"advertising":{"macros":{"AD_UNIT":"/23178111854/od.gizmodo.com/article","CHILD_UNIT":"article","POST_ID":"2000764654","POST_TYPE":"post","CHANNEL":"science","SECTION":"space","SUBSECTION":"","CATEGORIES":"space","TAGS":"space-weather,space-weather-forecasting,the-sun","NOP":"0"},"timeBeforeFirstAd":0}}}).render("cnx-player-main")}); When astronomers compiled 40 years’ worth of…
