Did the Hubble Telescope Confirm the First Exomoon?

The video discusses the potential discovery of the first exomoon orbiting Kepler 1625 B, a planet outside our solar system. Using data from the Hubble Space Telescope, scientists observed a light curve indicating a possible exomoon. The exomoon is thought to be Neptune-sized, orbiting a planet several times the mass of Jupiter. Further observations are needed to confirm its existence. The video also highlights the diversity of moons in our solar system and the importance of studying exomoons to understand planetary systems better. Future research will involve advanced telescopes like the James Webb Space Telescope.

How does the mass of the potential moon of Kepler 1625B compare to that of Neptune?

What future observations do scientists plan to conduct to confirm the existence of the exomoon?
