October Night Sky: A Cosmic Celebration
October is the perfect time to look up and marvel at the wonders of the universe. This month, we celebrate a major milestone in astronomy—ten years since scientists first detected gravitational waves. Gravitational waves, predicted by Albert Einstein in 1916, opened a new window into the cosmos when the Laser Interferometer Gravitational-Wave Observatory (LIGO) made the breakthrough in September 2015. 
Why Gravitational Waves Matter
Gravitational waves are ripples in space-time, created by cataclysmic cosmic events like merging black holes or neutron stars. Their discovery confirmed a century-old prediction and transformed our understanding of the universe. With LIGO’s advanced technology, astronomers can now detect and study these waves, revealing secrets of the most energetic and mysterious events in the universe. So, as you gaze at the night sky in October, remember the incredible journey of discovery that continues above us.
