Summary:
- NASA's upcoming Roman Telescope will be able to observe over 100,000 cosmic explosions, called supernovae, which are the violent deaths of massive stars.
- Studying these supernovae can help scientists better understand the expansion of the universe and the mysterious dark energy that drives this expansion.
- The Roman Telescope's ability to observe so many supernovae will provide valuable data to help solve some of the biggest mysteries about the universe, such as the nature of dark energy.
