  6. NASA's Parker Solar Probe Flew In And Out Of The Solar Corona And Found A Source Of High-Energy Particles That No Existing Model Had Predicted
    (When NASA's Parker Solar Probe passed through the solar corona during perihelion encounters at the heliospheric current sheet, its instruments recorded energetic protons at energies far above what existing models of particle acceleration at that location could account for.)

    “… A team… at the Southwest Research Institute… and… the University of Maryland’s Institute for Research in Electronics and Applied Physics has published an analysis of those measurements [link above]…, identifying magnetic reconnection at the heliospheric current sheet as the mechanism responsible. The proton energies detected were, in the study’s framing, approximately a thousand times greater than the available magnetic energy per particle that models of this process had predicted.
    The finding matters for two reasons: it identifies a source of energetic particles close to the Sun that was not anticipated, and it raises questions about how far the existing understanding of reconnection-driven particle acceleration extends…
    The Parker measurements suggest that picture needs revision. The magnetic island merging mechanism [the authors] identif[ied] can evidently produce proton populations at energies that challenge the boundary between what reconnection does and what shock acceleration does. Whether this source can explain a significant fraction of observed near-Earth energetic particle events, or whether it contributes mainly at energies and scales that remain confined close to the Sun, is a question the paper does not yet resolve…
    Solar Orbiter, the European Space Agency mission operating in coordination with Parker, offers complementary measurements at somewhat greater distances. Comparing what the two spacecraft measure of the same particle populations as they propagate outward from the Sun will help establish which features originate close to the source and which are modified by the intervening solar wind. The energetic particle observations that puzzled researchers in the pre-Parker era now have a candidate mechanism. Whether that mechanism accounts for a large or small fraction of what actually reaches Earth remains the open question…”

    The word perihelion refers to the exact point in an object's orbit where it is closest to the Sun.

    Comets spend most of their lives frozen and dormant in the dark outer edges of the solar system. But as they approach perihelion, the Sun's intense thermal heat causes the subsurface ice inside the comet to violently vaporize (sublimation), blasting out massive jets of gas and dust into space.

  18. The new #Kreutz #comet is now C/2026 A1 (MAPS): cbat.eps.harvard.edu/iau/cbet/ and spaceobs.com/en/Alain-Maury-s- and minorplanetcenter.net/mpec/K26 - whether it will reach and survive #perihelion is highly uncertain but there is hope as facebook.com/groups/2270023586 and groups.io/g/comets-ml/topic/11 explain. And if MAPS makes it to perihelion and is (very) bright then coronagraphs on the ground might be able to catch it against the inner corona as the following table - calculated with ssd.jpl.nasa.gov/horizons/app. - shows.

  33. Happy #Perihelion Day, at a boot 12:15.
    We will b a boot 147,099,894 km from the Sun's center to Earth's center .
    timeanddate.com/astronomy/peri

    Bonus wind b dying down, da main roads seem 2 b reopened.

    What 2 do when stuck inside 4 a few days? How a boot make some Simple Simon Aloo Gobi [or as da local Indian Restaurant calls it " #Vegan Squad".

    4 an authentic Indian restaurant they have some unique food names like, "Subz Popsicle (Vegetable Pakora)"

    new.ruhungry.ca/kinssocial/men

    Finally figured out Y I can't watch vids recorded from my phone on either my lappy or desktop. Or at least I get a message as 2 Y.

    So what it is saying is that I got a Windows update so a PC with NEWER hardware can play certain vids with certain extensions, BUTT not older hardware with older extensions???

    Now gotta figure out how 2 fix it.

  35. #Earth's #Perihelion occurs today (in fact in just under three and a half hours from the time of writing) at 17:15Z. That’s when our planet is at its closest to the #Sun, at around a distance of 147 million km. The mean is about 150 million km and the maximum (aphelion) will occur precisely half a year from now and we’ll be about 152 million km from it. A difference of 5 million km sounds a lot but the Earth’s orbit is almost circular with and #eccentricity of just 0.0167.
