A Stunning Discovery 400 Light-Years Away

In an extraordinary breakthrough, citizen scientists have teamed up with NASA's TESS (Transiting Exoplanet Survey Satellite) to uncover a fascinating new gas giant known as TOI-4465 b, located roughly 400 light-years from our home planet. This alien world is not just cool in temperature; it’s a game changer in our understanding of celestial bodies!

Meet TOI-4465 b: Size, Mass, and Orbits

This newfound exoplanet boasts a mass about six times greater than Jupiter and measures 1.25 times its width. TOI-4465 b orbits its star at just 0.4 times the distance between Earth and the Sun, completing a year in approximately 102 Earth days. Its unique, elliptical orbit results in temperatures ranging from a brisk 200 to 400 degrees Fahrenheit (93 to 204 degrees Celsius), making it a rare specimen among gas giants.

A Glimpse into an Underexplored Region of Space

This discovery marks an essential addition to the catalog of exoplanets, particularly because TOI-4465 b fills a significant gap between the notoriously hot "hot Jupiters" and the icy realms of planets like Neptune and Uranus. As team leader Zahra Essack from the University of Mexico notes, long-period exoplanets—those with orbits over 100 days—are rarely found, emphasizing the importance of studying these intriguing worlds.

How TESS Made the Encounter Possible

So how did TESS spot this elusive planet? The spacecraft detects planets by monitoring slight dips in starlight caused when they transit across their parent stars. TOI-4465 b was initially identified during a fleeting transit, but confirmation required observing another transit, a task laden with challenges due to limited observational windows.

Citizen Scientists to the Rescue!

To overcome these hurdles, the research team engaged the Unistellar Citizen Science Network, rallying 24 dedicated amateur astronomers from 10 different countries. Armed with their personal telescopes, these citizen scientists gathered valuable data, which, when combined with findings from professional observatories, culminated in the confirmed existence of TOI-4465 b.

The Power of Collaboration in Astronomy

Essack emphasizes that this achievement demonstrates the invaluable role that citizen science can play in advancing our understanding of the universe. Global collaborations, including the TESS Follow-up Observing Program and the TESS Single Transit Planet Candidate Working Group, propelled this project forward.

In a world where astronomical discoveries are becoming increasingly common, TOI-4465 b stands out as a testament to the power of teamwork in the pursuit of knowledge—a true win for science enthusiasts and explorers alike!
