Citizen Scientists Help Confirm New Gas Giant Exoplanet TOI-4465b
In a remarkable display of collaborative science, amateur astronomers armed with Unistellar eVscope smart telescopes have contributed significantly to confirming the existence of a new gas giant exoplanet, named TOI-4465b. This planet, located approximately 400 light-years from Earth, presents a fascinating case study in how citizen science is advancing our understanding of the cosmos.
The Discovery of TOI-4465b
TOI-4465b was initially identified by NASA's Transiting Exoplanet Survey Satellite (TESS) as a potential single-transit event. This means TESS observed a brief dip in the star's brightness, suggesting a planet might have passed in front of it. However, to confirm a planet's existence, especially one with a long orbital period, multiple transits need to be observed. TOI-4465b's transit occurs only once every 102 days, making confirmation a challenging task.
The Power of Citizen Science
This is where the global network of Unistellar participants stepped in. Their observations were crucial for catching the elusive second transit needed to validate TOI-4465b. This collaborative effort demonstrates the immense value of citizen scientists in modern astronomical research, supplementing the work of professional astronomers and large observatories.

Characterizing the Gas Giant
Beyond citizen science contributions, the confirmation of TOI-4465b also involved follow-up observations from large professional telescopes, including radial velocity measurements. These studies have revealed more about this distant world. TOI-4465b is a gas giant with a radius about 1.25 times that of Jupiter and a mass approximately 5.89 times greater than Jupiter's.

This discovery is a testament to the power of distributed observation and the increasing accessibility of cutting-edge astronomical research to the public.
