Preguntas frecuentes: La verdadera historia del cuidado de la salud de los astronautas en el espacio
NASA explores the not known in air and House, innovates for the advantage of humanity, and conjures up the entire world via discovery.
HOST PADI BOYD:So what is this substance that is definitely so typical within our cosmos but nonetheless puzzling scientists listed here on our household World?
Hi, I’m Doug Rowland. And that i’m a scientist researching the Earth’s higher atmosphere. Which’s a fascinating region, as it’s wherever the Earth’s environment that we breathe, turns right into a fuel called plasma that’s electrically charged.
When a lightning discharge happens, you realize, you see that flash through the sky? Effectively, that flash is caused by an electrical recent, which heats the ordinary gasoline nearly an extremely significant temperature and tends to make a plasma column, which glows. And that’s Anything you see because the lightning flash.
a refrain wave. Examining Appears may also help researchers superior understand the other ways plasma behaves.
HOST PADI BOYD: Don Gurnett has expended his profession finding out plasmas and plasma physics. To start discussing plasmas, you have to start with a gas. And to turn that fuel into a plasma, we’ve received to incorporate a little bit of Vitality.
HOST PADI BOYD:Even now curious about NASA? It is possible to send us questions about this episode or maybe a prior just one and we’ll try to track down the solutions! You can e-mail a voice recording or send out a written Be aware to [email protected]. Check out nasa.gov/curiousuniverse for more information.
If you could potentially strip the electron off of the atom so which the electrons are no cost, Then you definitely have electrons and good ions, that’s known as a plasma.
HOST PADI BOYD:Plus the even more we start to get faraway from Earth’s fairly neutral floor, the greater normally we can discover these electrically charged gases.
The secondary goals on the mission involve crew assistance of EarthKAM, an ongoing experiment to supply middle university pupils with observations with the World from Area.
This spectacular image captures a little location on the edge of your inky Coalsack Nebula, or Caldwell 99. Caldwell ninety nine is a darkish nebula — a dense cloud of interstellar nasa99 dust that wholly blocks out noticeable wavelengths of sunshine from objects behind it. The item at the middle in the impression is a (Considerably smaller) protoplanetary nebula.
NASA explores the unfamiliar in air and space, innovates for the advantage of humanity, and inspires the earth via discovery.
This graphic, taken via the NASA/ESA Hubble House Telescope, reveals an in depth watch with the spiral arms on just one aspect on the galaxy Messier 99. Messier ninety nine is usually a so-termed grand design spiral, with extensive, significant and Plainly outlined spiral arms — giving it a composition rather just like the Milky Way.
