Every yr or two, the photo voltaic system traces up excellent, with the moon casting a shadow over a part of Earth’s floor and blocking out the solar—a photo voltaic eclipse. In 2017, folks throughout the United States flocked to see the “Great American Total Eclipse”, which was the first one seen in the continental states since 1979. Now, eclipse chasers and citizen scientists throughout North America are preparing for the subsequent large occasions: an annular eclipse on October 14, 2023 and a complete eclipse on April 8, 2024. This can be the final eclipse seen in the continental US till August 2045, greater than twenty years away.
People love eclipses for the novelty—how cool it’s to see the solar disappear in the day. But these phenomena are each showstoppers and alternatives: a gaggle of radio astronomers and citizen scientists known as Radio JOVE is aiming to capitalize on the upcoming eclipses for science, a part of NASA’s “Helio Big Year.”
Radio JOVE “initially started as an education and outreach project to help students, teachers, and the general public get involved in science,” explains challenge co-founder Chuck Higgins, an astronomer at Middle Tennessee State University. The challenge has been working since the late Nineties, when it started at NASA’s Goddard Space Flight Center. “We now focus on science and try to inspire people to become citizen scientists.”
As its title suggests, Radio JOVE initially targeted on the Jovian planet, Jupiter. “Serendipitously, it turns out that the same radio wavelengths we use for observing Jupiter are also useful for observing the sun,” says Thomas Ashcraft, a citizen scientist from New Mexico who has been observing with Radio JOVE since 2001. After the 2017 Great American Eclipse, its members grew to become extra concerned with heliophysics, the research of the solar.

As vitality spews from the solar and travels to Earth, it interacts with our planet’s ambiance; in specific, the solar’s rays create a layer of ionized particles, generally known as the ionosphere. Any radio waves coming from the solar must go by means of these particles above us. Communication expertise takes benefit of this layer, bouncing radio waves off it to journey lengthy distances.
The ionosphere’s plasma modifications lots between day and evening. When the solar shines on this layer, particles break into ions. When the solar is absent, these ions relax. During eclipses, when most of the solar’s mild is blocked, related modifications occur in the brief time period change. By measuring these fluctuations exactly with a fleet of newbie observers, Radio JOVE hopes to enhance our understanding of the ionosphere.
To achieve this, Radio JOVE is equipping citizen scientists throughout the nation with small radio receivers and coaching them to look at radio waves from Earth’s ionosphere. The challenge presents some-assembly-required starter kits for round $200, and a complete crew of specialists and skilled observers are round to help new volunteers.

Right now, they’re prepping members for a full day of observing throughout the October annular eclipse. Project members are already gathering information to have a baseline of the solar’s affect on a traditional day, which they’ll evaluate to the upcoming eclipse information. And that is solely a small style earlier than the large occasion: subsequent yr’s whole eclipse. “The 2023 annular eclipse will be used as a training, learning, and testing experience in an effort to achieve the highest quality data for the 2024 total eclipse,” Higgins wrote in a abstract for an American Geophysical Union convention.
Citizen science tasks comparable to Radio JOVE not solely accumulate priceless information, however in addition they contain a brand new crowd in NASA’s scientific neighborhood. Anyone in science can be a part of in, and if Radio JOVE doesn’t fit your pursuits, NASA has a protracted checklist of different alternatives. For instance, when you’re a ham radio operator, you can become involved with HamSCI, which additionally plans to look at the upcoming eclipse.
“NASA’s Radio JOVE Citizen Science Project allows me to further explore my lifelong interest in astronomy,” stated John Cox, a Radio JOVE citizen scientist from South Carolina, in a NASA press launch. “A whole new portion of the electromagnetic spectrum is now open to me.”
