The search for life: Are we alone in the universe?

Looking up at the stars at night, it’s hard not to ask the question of whether we are alone in the universe or not. The universe is an unfathomably large place, with 200-400 billion stars in our galaxy, The Milky Way, alone. Yet our galaxy is one of billions of other galaxies, some having many more stars than ours does. How likely is it that Earth is the only planet harboring life? How are scientists looking for life in our galaxy and beyond? What kind of life are they looking for?

So far we know only one place in the universe that has life: Earth. Does that mean that we might have a limited definition of what life might look like? Even on our own planet, life is more resilient than we previously thought. There is barely a corner of Earth that doesn’t harbor life in some form. From the deepest oceans, to the driest deserts, the highest mountains, and the coldest glaciers, life has been found in all the extremes. When we look for life in the universe, how do we know we are looking in the right place?

These questions and more will attempted to be answered during this conversation organized by Akademisk Vorspiel. We are lucky enough to be joined by Signe Riemer-Sørensen, a postdoc at the University of Oslo who works on the secrets behind dark matter. We will also be joined by Lluis Mas Ribas, also a postdoc at the University of Oslo, who works on radiation produced by stars.

This event will be held in English, and is suited for everyone, regardless of previous knowledge in astrophysics. There will of course be an opportunity for questions after the conversation.

The moderator for this event will be Simon Kline, a biology student at the University of Oslo.

The conversation is of course free for everyone to come, and will be held in the library on the second floor of Chateau Neuf.
