I The Sun's excess gamma rays and strange dips

AI Thread Summary
Recent observations have shown that the Sun emits gamma rays seven times more abundantly than previously expected, presenting a significant mystery in astrophysics. Despite this excess, there is a notable absence of gamma rays at a specific frequency of 10 trillion trillion hertz, raising questions about the Sun's magnetic field and its effects. Experts remain uncertain about the cause of this dip, with some doubting its authenticity, although no instrumental errors have been confirmed. Ongoing research and modeling efforts are focused on understanding these phenomena. The scientific community is actively engaged in unraveling this complex issue.

Any theory what could be causing the excess gamma ray and the strange dips in the sun?

"A decade’s worth of telescope observations of the sun have revealed a startling mystery: Gamma rays, the highest frequency waves of light, radiate from our nearest star seven times more abundantly than expected. Stranger still, despite this extreme excess of gamma rays overall, a narrow bandwidth of frequencies is curiously absent."

"But there are no good guesses about how the sun’s magnetic field might create the dip in the gamma-ray spectrum at 10 trillion trillion hertz. It’s such an unusual feature that some experts doubt that it’s real. But if the absence of gamma rays around that frequency is a miscalculation or a problem with Fermi’s instruments, no one has figured out the cause. “It does not seem to be any instrumental effect,” said Elena Orlando, an astrophysicist at Stanford and a member of the Fermi team."

I think the article pretty much answers your question. No, we don’t have a good theory on it yet but people are interested and are modeling and studying it to understand why.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
