Photo voltaic flares might be many occasions the scale of Earth and might injury issues like satellites. A brand new examine means that eruptions from the solar might be even hotter than researchers thought.



JUANA SUMMERS, HOST:

Photo voltaic flares are intense bursts of sunshine and particles from the solar. Whereas they will pose hazards for issues like satellites, these flares are additionally lovely, dramatic and extremely sizzling. NPR’s Nell Greenfieldboyce stories on simply how excessive the temperatures can get.

NELL GREENFIELDBOYCE, BYLINE: The solar is sizzling – no duh – however how sizzling is it? Alexander Russell is with the College of St. Andrews in Scotland. He says completely different elements of the solar have completely different temperatures. The core is round 27 million levels Fahrenheit. It is hotter than the floor, which is just round 10,000 levels.

ALEXANDER RUSSELL: After which it really begins to get hotter as you progress out into the outer layer.

GREENFIELDBOYCE: That outer layer is the ghostly ring you see throughout a complete photo voltaic eclipse. It may be over 2 million levels. What Russell needed to know was the temperature of photo voltaic flares. These flares erupt when a sudden launch of magnetic vitality sends particles taking pictures out. There’s two sorts of particles – electrons and ions. Telescopes flares can measure the temperature of the electrons.

RUSSELL: And we have sort of simply assumed, properly, the ion temperature can be the identical because the electron temperature.

GREENFIELDBOYCE: The difficulty is, that does not appear to be true, not less than not in response to latest pc simulations and measurements in near-Earth area. They are saying that really, ions can get manner hotter than electrons. So Russell and his colleagues did some calculations, and so they now say that photo voltaic flares could possibly be greater than six occasions hotter than beforehand identified – over 100 million levels Fahrenheit, possibly even as much as 180 million.

RUSSELL: Which is sort of a loopy quantity.

GREENFIELDBOYCE: They’ve printed their evaluation in Astrophysical Journal Letters. One one that was pleased to see it’s James Drake. He is a physicist on the College of Maryland. He and his analysis companions have lengthy been learning how magnetic vitality will get dumped into particles like electrons and ions. He says the distinction between the 2 has been neglected in the case of photo voltaic flares.

JAMES DRAKE: We have been confronting the photo voltaic physicists, telling them that though they’ve measured in loads of element what is going on on with the electrons, they’re lacking one thing large.

GREENFIELDBOYCE: He says including this piece in ought to enhance scientists’ understanding of how photo voltaic flares and their related phenomena really work, which may assist defend {hardware} like satellites and folks like astronauts from these harmful however superior eruptions.
