This article is part of a special report on the total solar eclipse that will be visible from parts of the U.S., Mexico and Canada on April 8, 2024.

Maybe you didn’t know that a total solar eclipse would cross North America on April 8. Maybe you won’t be able to travel to an area in the path of totality. Maybe your view will be obscured by clouds.

Never fear: if all else fails, you can watch the rare spectacle online, thanks to a handful of livestreams designed to share the eclipse with viewers around the globe.

First up, check out Scientific American’s own livestream. We’ll be offering a view of the eclipse that you can’t catch from anywhere on the ground, even with a “perfect location” and clear skies: a team of researchers will be using two jets from NASA’s WB-57 High Altitude Research Program that were converted into high-flying telescopes to chase the eclipse for science.

When the team made its first eclipse flight during 2017’s coast-to-coast spectacle, the scientists produced high-resolution images of the sun’s outer atmosphere, or corona, in a wavelength of light in which it had never been captured before. By flying along the path of totality, the researchers also stretched their view of this total solar eclipse to about seven and a half minutes—despite the fact that no place on Earth experienced totality for longer than two minutes and 42 seconds.

This spring’s eclipse is even more promising because it will last up to four minutes and 28 seconds on the ground. In the jet-based observation effort, the researchers hope to stretch that to eight minutes aloft. And during their flight this eclipse, the planes will carry upgraded instruments. The jets will also be equipped with new experiments, including one used to study material leaving the sun, such as the blobs of plasma and magnetic field dubbed coronal mass ejections and the steady stream of charged particles known as the solar…
