Catch a Dying Star: Astronomy Deep Underground

Explore the Wonders of the Universe: A Deep Talks Lecture on Supernovae

Join Dr. Stephen Sekula, Research Group Manager at SNOLAB, for an engaging and thought-provoking Deep Talks event focused on the incredible story of supernovae and their role in transforming modern astronomy. This lecture explores an event from the distant past that reshaped our understanding of the universe and introduced us to new, invisible messengers from space.

The Supernova That Changed Astronomy

Around 168,000 years ago, a massive star exploded in a neighboring galaxy, releasing an incredible amount of energy. The first signals of this catastrophic event reached Earth in the late 1980s, leading to a groundbreaking moment in astronomy. This explosion was more than just a spectacular light show—it marked the beginning of a new era in science, shifting our focus from the visible to the invisible forces that permeate the cosmos.

Invisible Messengers: Neutrinos and Beyond

Supernovae not only illuminate the sky but also send out a torrent of invisible particles, like neutrinos, which can travel unimpeded across vast expanses of space. Detecting these elusive particles is a challenge, but their importance cannot be overstated. They give us a glimpse into the heart of stars, offering critical insights into their life cycles, including the processes that govern our own Sun.

Global Networks: Early Warning Systems for the Future

Thanks to the lessons learned from studying past supernovae, a global network of early warning systems has been established to detect such events before they reach their peak. These networks track and analyze signals, helping scientists forecast the deaths of distant stars. By studying supernovae, we gain not only a better understanding of the universe’s workings but also a way to predict future astronomical phenomena.

A Must-Attend Event for Astronomy Enthusiasts

Dr. Sekula’s lecture is a unique opportunity to dive into the science of supernovae and the invisible particles that help unlock the mysteries of the universe. Whether you’re a budding astronomer or simply curious about the cosmos, this event promises to deepen your understanding of the fundamental forces shaping our world. Don’t miss the chance to be part of this fascinating journey through space and time!
