Astronomers Spot the Debris From Planets That Formed 10 Billion Years ago
The fate of the Sun is sealed. It was sealed by gravity in the earliest days of its formation. In several billion years the Sun will swell to a red giant, cast off much of its thin outer layers, then collapse to become a white dwarf. The white dwarfs we see in the nearby galaxy tell us of our Sun’s future. Its core will collapse to about the size of Earth, and then it will gradually cool as it fades into the dark. It’s a tale we’ve long known, but astronomers continue to learn learning interesting details, particularly regarding what might be the fate of the Sun’s planets.

Searching for Life on Highly Eccentric Exoplanets
When we think about finding life beyond Earth, especially on exoplanets, we immediately want to search for the next Earth, or Earth 2.0. We want an exoplanet that orbits a star firmly in its habitable zone (HZ) with vast oceans of liquid water, and plenty of land to go around. An exoplanet like that most certainly has life, right? But what if we’re looking in the wrong places? What if we find life on exoplanets that don’t possess the aforementioned characteristics, i.e., Earth 2.0?
