Solar Eclipse 2019 Live: Watching the Astronomical Event Online | Internet

The 2019 solar eclipse will take place this Tuesday (2), from 4:48 pm, in Brasilia time, and will be broadcast live by NASA. The phenomenon can only be seen in person in some areas of South America, between Chile and Argentina. The US agency, which last year broadcast the lunar eclipse via the NASA app, will re-display the astronomical event on the Internet. The solar eclipse is a phenomenon in which the moon casts a shadow over the earth, completely and / or partially obscuring sunlight in some parts of the planet.

NASA's broadcast proposal allows people from all over the world to watch the eclipse. The initiative was made through a partnership with the Exploratorium laboratory, a museum located in So Francisco.

The astronomical phenomenon is of utmost importance to NASA as it allows scientists to analyze the source and behavior of the sun's rays. These data may impact future space missions as they affect issues such as durability of space materials and health of astronauts. The eclipse can also cause changes in the planning of space missions scheduled for 2024.

Will the eclipse appear in Brazil?

According to the National Observatory, the eclipse will be visible to some Brazilian capitals with varying percentages of visibility. The southern region is privileged because the phenomenon appears best in a narrow range between Chile and Argentina. Therefore, Porto Alegre has 75% visibility of the eclipse, while northern cities, such as So Paulo and Rio de Janeiro, have estimated just over 40% visibility.

It should be noted that there are risks to the naked eye bystanders who do not protect themselves. Therefore, NASA has provided some recommendations for those who choose to view the eclipse directly. Just them:

  • Do not look directly at the sun without the use of specialized equipment;
  • Make use of solar glasses made for eclipses. The use of ordinary sunglasses or radiographs is not recommended and may cause permanent eye damage;
  • Care must also be taken with equipment such as camera lenses, which may be damaged.
