NASA spacecraft films crazy vortex as it flies through the sun’s atmosphere | Trending Viral hub


He fastest spaceship in our solar system has captured wild images within the sun’s atmosphere.

from NASA Parker solar probe — a ship that flies much closer to the sun than any previous mission, it witnessed massive “vortex-like structures” in our star’s outer atmosphere, called the corona. You can see the unprecedented view below, taken by the probe’s WISPR camera (short for Parker Solar Probe’s Wide-field Imager) and recently posted online.

Researchers suspect that the phenomenon was caused by a coronal mass ejection (CME) — when the sun expels a mass of super-hot gas (plasma) toward space — interacting with the solar wind. The solar wind from the sun is constant, like ours medium size star It emits a constant stream of charged particles.

The new research associated with the footage, published in The Astrophysical Magazineconcluded that this discovery in unexplored realms of the sun has created new opportunities to better understand and predict CMEs, explosions that can severely damage communications and power grids in Land. Technically, these rare vortices are called “Kelvin-Helmholtz instabilities” or KHI.

Crushable speed of light

“Direct imaging of extraordinary ephemeral phenomena like KHI with WISPR/PSP is a discovery that opens a new window to better understand the propagation of CMEs and their interaction with the ambient solar wind,” said space weather researcher Evangelos Paouris. and member of the WISPR team. at George Mason University, he said in a statement.

CMEs “can endanger satellites, disrupt communications and navigation technologies, and even disable Earth’s power grids.” POT Explain. It is infamous that a powerful CME in 1989 left millions of people without power in Quebec, Canada. The CME collided with Earth’s magnetic field on March 12 of that year and then, wrote NASA astronomer Sten Odenwald, “shortly after 2:44 a.m. on March 13, the currents found a weakness in the Quebec’s power grid. In less than two minutes, Quebec’s entire power grid lost power. During the 12-hour blackout that followed, millions of people suddenly found themselves in dark office buildings, in underground pedestrian tunnels and in stopped elevators.”

The space agency’s Parker solar probe will continue its dives at full speed in the crown of the sun. To resist heat, it is reinforced with a 4.5-inch-thick carbon heat shield that faces the sun. The shield itself heats up to about 2,500 degrees Fahrenheit, but just a couple of feet behind the shield, the environment is surprisingly mild.

Later this year, the spacecraft will reach a whopping 430,000 miles per hour.
