Gazing at the night sky, we naturally wonder what lies beyond our atmosphere. Astrophysics, the study of the universe beyond our reach, tackles these very questions. However, understanding celestial objects presents a unique challenge. Unlike objects we can directly interact with, measuring fundamental properties like distance, mass, temperature, and pressure for these distant bodies is incredibly difficult. All we have to unravel their secrets is the light they emit. This talk offers a taste of the diverse and exciting research happening in this field. This talk will also touch upon the tools astrophysicists use to unravel the universe's secrets, including a virtual visit to an astronomical observatory housing powerful telescopes. By the end, you will gain a deeper appreciation for the vastness and wonder of the universe and how researchers are piecing together its secrets through the faint whispers of light.
