LIVE: NASA Scientist Arcand Talks Black Holes, Asteroids & Total Solar Eclipse
Arcand says black holes aren’t really giant vacuum cleaners as science fiction makes them out them to be.
In fact, Arcand describes the black hole at the center Milky Way galaxy astronomers have named Sagittarius A as “chill.”
Black holes can range in size and using the Chandra satellite, Arcand says astronomers can learn more about how they influence what’s around them.
The total solar eclipse is August 21, which means the sun, moon and Earth will all line up and the sun’s light will be blocked by the moon.
Arcand says there won’t be a total eclipse in Rhode Island, but about a 65% coverage will be visible. She explained that you must wear proper eclipse glasses to see the eclipse and make sure you’re in place to see it by 2:30 p.m.
Arcand says there are some unexpected things that happen with an eclipse, like temperature drop and it can get so dark that insects get confused.
