In our Solar System, moons can be more fascinating than planets. They host incredible features like volcanoes, vast seas of hydrocarbons, and icy oceans hidden beneath their surfaces. Given how planets form, it’s logical to believe moons should be plentiful across the galaxy.
However, we’ve yet to find a clear example of a moon orbiting an exoplanet. What we do see are young exoplanets with disks around them that suggest the potential for moon formation. The James Webb Space Telescope recently captured data showing a rich array of small carbon-based molecules in a disk around a giant exoplanet called a super-Jupiter. Interestingly, the star it orbits mostly has water in its own planet-forming disk.
To discover exo-moons, scientists use different techniques. One way is to observe their gravitational pull. As a moon orbits, it influences its planet’s movement. Sometimes, it speeds up the planet, and other times it slows it down. This creates subtle timing changes in how we see the planet transit in front of its star.
There’s also the method of looking for moon-forming disks, which only appear early in a solar system’s life. These disks are like larger versions of Saturn’s rings, holding enough material to eventually form moons. Over millions of years, this material can either spread out, condense into moons, or merge into the planet itself.
Understanding these processes is crucial. A recent study found that nearly 60% of stars similar to our Sun host planets. If many of these planets have moons, it suggests that our galaxy could be teeming with these celestial bodies, just waiting to be discovered. Additionally, social media buzz around space exploration shows a growing curiosity about moons and exoplanets, especially among younger audiences excited about new discoveries from missions like the James Webb Space Telescope.
As we continue this exploration, every new finding brings us a step closer to uncovering the secrets of moons beyond our Solar System.
