The Habitable Worlds Observatory could See Lunar and Solar ‘Exo-Eclipses’

A future space observatory could use exo-eclipses to tease out exomoon populations.

If you’re like us, you’re still coming down from the celestial euphoria that was last month’s total solar eclipse. The spectacle of the moon blocking out the sun has also provided astronomers with unique scientific opportunities in the past, from the discovery of helium to proof for general relativity. Now, eclipses in remote exoplanetary systems could aid in the hunt for elusive exomoons.

A recent study out of the University of Michigan in partnership with Johns Hopkins APL and the Department of Physics and the Kavli Institute for Astrophysics and Space Research at th...

Kepler, don’t give up on the Hunt for Exomoons

    This simulation shows the collision of two celestial bodies, ejecting enough debris into orbit to form a moon large enough for the Kelper spacecraft to detect.

The Kepler spacecraft has been prolific in its search for exoplanets, discovering thousands since its launch in 2009. But the hunt for moons orbiting these exoplanets, or exomoons, is vastly more challenging. While no exomoons have been found to date, a new study shows that the search is not futile. Researchers have demonstrated for the first time that it is possible for a planetary collision to form a moon large enough for Kepler to detect. Lawrence Livermore National Laboratory physicist Megan Bruk Syal and Amy Barr of the Planetary Science Institute conducted 30 simulations to explore how various factors affect moon creation...
