Today we're teaming up with Joe Scott to look at the Great Attractor, a mysterious and massive source of gravity obscured from our vision, and the concept of Dark Flow, movements of whole clusters of galaxies in directions with no obvious cause.

To see deeper into space, we will need much bigger telescopes.
Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
As astronomy seeks to find and study distant planets and peer further and more accurately into space and time, the limitations of ground based telescopes, especially optical telescopes, represents our largest barrier. Today we will examine what those limitations are, and ways to make vastly more enormous telescopes and arrays.

A visit to Ceres and the Asteroid Belt.
Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
Ceres, a dwarf planet amid the Asteroid Belt, hold the potential to be the hub of a vast mining and manufacturing network in the Belt, as well as potentially growing the food to support future colonists. Today we'll look at colonizing Ceres and asteroid mining, faming in space, and a potential distant future of a developed asteroid belt.

The possibility that ancient civilizations might have encountered or even been influenced by extraterrestrials has fascinated us for as long as we knew there were distant suns they might visit from. Today we will examine the evidence and consider the numerous scenarios form the perspective of the Fermi Paradox, to see how reasonable the Ancient Aliens hypothesis is, and ask if the evidence of UFOs visiting us in the past is credible.

Today we take a trip inward, to explore Sun-Scorched Mercury.
Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
Mercury is the nearest planet to the Sun, a seeming airless wasteland little discussed in conversations about colonizing our solar system. Today we will challenge that, and show that Mercury may be one of the most promising places for humanity to make new homes on.

Astronomers have been looking for signs of extraterrestrial signals for decades, and not yet found any. Today we will examine the notion of Interstellar Beacons and ask just how far away you can be heard if you want to be.
