Q&A: Hubble Finds Evidence of Possible Exomoon

The video discusses the excitement around the discovery of a potential exomoon, its characteristics, and the methods used to detect it, such as the transit method. Experts explain the role of telescopes like Kepler and Hubble in this discovery and the future potential of the James Webb Space Telescope. The video also addresses questions about the possibility of life on exomoons and the challenges of detecting them. Additionally, it highlights NASA's 60th anniversary and Hubble's contributions to space exploration.

What is an exomoon?

• A planet orbiting a star outside our solar system

• A moon within our solar system
