"First off, this won’t happen for another 5 billion years; since the Sun is only 4.5 billion years old, it’s not even halfway there." Thea Kozakis (

"Secondly, even though this would be the end of life for the inner Solar System, it could potentially be the beginning of a new era of life for the outer Solar System." Thea Kozakis (

"During this phase of the Sun’s life the habitable zone, the region of space where liquid water could exist on the surface of a planet, will move into the outer Solar System, where over 99% of our system’s water resides." Thea Kozakis (

"In particular, both Jupiter and Saturn along with their 100+ moons will enter this zone, introducing a chance to develop or reveal unique types of life." Thea Kozakis (

"Although two of these moons, Europa and Enceladus, currently have liquid water oceans, their icy shells shield us from remotely detecting any life that may reside there." Thea Kozakis (

“When a star ages and brightens, the habitable zone moves outward and you’re basically giving a second wind to a planetary system.” Dr. Ramses M. Ramirez

“In the far future, such worlds could become habitable around small red suns for billions of years, maybe even starting life, just like Earth. That makes me very optimistic for the chances for life in the long run.”
