But significant cuts to NASA this year are hurting programs across the board, and many worry that the future looks grim for NASA's astronomy programs due to two growing problems on its horizon.

Our lifespans might feel like a long time by human standards, but to the Earth it's the blink of an eye. Even the entirety of human history represents a tiny slither of the vast chronology for our planet. We often think about geological time when looking back into the past, but today we look ahead.

For billions of years the Sun has been the perpetual, life-giving star in our sky. It's a force of immense power, yet one we take for granted in our every day lives. But like all things, it too must eventually end. Today, we chronicle the future of our home star, its various phases, why this all happens, and the final fate of our Solar System.Written and presented by Prof David Kipping. Edited by Jorge Casas.

The Cool Worlds Lab is trying to find the first exomoon, a moon around a planet outside the Solar System. But, exomoons have been eluding us for a few years now.

Earth-sized planets found in the habitable-zones of low-mass stars are likely to become tidally locked to the star, with one side baked in perpetual sunlight and other trapped in an eternal night. These so-called "Eyeball Earths" turn out to be extremely common and some famous examples include Proxima b and the planets around TRAPPIST-1. Here, we explain why this tidal locking happens and what it means for the potential habitability of these alien worlds.::More about this Video::► "Discovery of a Planet around our Nearest Star: Proxima b" Cool Worlds video by Dr Guillem Anglada: https://youtu.be/59ClESB1AqA► "Proxima b: Transits, Habitability & How to Get There!"
