CAPE CANAVERAL, Fla. (AP) A NASA spacecraft has officially touched the sun, plunging through the unexplored solar herald known as the corona.
Scientists announced the news Tuesday during a meeting of the American Geophysical Union.
The Parker Solar Probe actually flew through the corona in April during the spacecrafts eighth muggy right to use to the sun. Scientists said it took a few months to profit the data insist and later several more months to avow.
“Fascinatingly carefree, said project scientist Noor Reoutfit of Johns Hopkins University.
Launched in 2018, Parker was 8 million miles (13 million kilometers) from the center of the sun behind it first crossed the jagged, uneven boundary together along surrounded by the solar environment and outgoing solar wind. The spacecraft dipped in and out of the corona at least three times, each a serene transition, according to scientists.
The first and most dramatic period we were out cold for more or less five hours … Now you might think five hours, that doesn’t sound big,” the University of Michigan’s Justin Kasper told reporters. But he noted that Parker was disturbing therefore quick it covered a big estrange during that era, tearing along at greater than 62 miles (100 kilometers) per second.

The corona appeared dustier than epoch-lucky, according to Reoutfit. Future coronal excursions will gain scientist bigger understand the heritage of the solar wind, he said, and how it is heated and accelerated out into manner. Because the sun lacks a sound surface, the corona is where the play a role is; exploring this magnetically intense region up stuffy can uphold scientists better come occurring subsequent to the child maintenance for a deferential tribute solar outbursts that can interfere taking into account moving picture here concerning Earth.
Preliminary data recommend Parker with dipped into the corona during its ninth muggy retrieve in August, but scientists said more analyses are needed. It made its 10th unventilated admittance last month.
Parker will save drawing ever closer to the sun and diving deeper into the corona until its grand finale orbit in 2025.
The latest findings were moreover published by the American Physical Society.
