The space agency hopes to better understand some of the biggest mysteries about the sun.
During the total solar eclipse on Monday, April 8, when the moon will temporarily obscure the sun's face from view for millions of people across Mexico, the United States and Canada, multiple experiments will be underway to better understand some of the biggest unresolved questions about the golden orb.
Einstein had suggested gravity is the result of the warping of time and space, distorting the very fabric of the universe. As an example, Einstein proposed that the gravitational influence of a large object like the sun could deflect light emitted by another object, such as a star virtually behind it, causing the object to appear a bit farther away from the perspective of Earth.
Why the corona is millions of degrees hotter than the sun's actual surface is one of the enduring mysteries about our star. A 2021 study revealed some new clues, showing that the corona maintains a constant temperature, despite the fact that the sun experiences an 11-year cycle of waning and increasing activity. The findings were possible thanks to more than a decade's worth of eclipse observations, according to NASA.
Tourists on the American side of Niagara Falls take photos in Niagara Falls, N.Y. on Friday, March 29, 2024. Ontario's Niagara Region has declared a state of emergency as it readies to welcome up to a million visitors for the solar eclipse on April 8. Observing the sun during eclipses also helps scientists better understand how solar material flows from the sun.
In another repeat experiment, three sounding rockets will lift off in succession from NASA's Wallops Flight Facility in Virginia before, during and after the eclipse to measure how the sudden disappearance of sunlight impacts Earth's upper atmosphere.Laverne Biser has witnessed 12 solar eclipses in his life and he's ready to watch his 13th on April 8.
"Understanding the ionosphere and developing models to help us predict disturbances is crucial to making sure our increasingly communication-dependent world operates smoothly," Barjatya said in a statement.During the 2023 annular eclipse, instruments on the rockets measured sharp, immediate changes in the ionosphere.
