"That's home. That's us." Carl Sagan

As we gaze at the beauty of our own Earth, we can't help but wonder if life exists out there in the cosmos

Astronomers now have some new places to search for life! 👀

In a new paper today, Carl Sagan Institute fellows have identified 45 potentially Earth-like worlds

Artist’s impressions of planetary systems around different stars than our Sun. One image depicts a purple planet orbiting a redder star, which could cause microbes and plants on the planet's surface to reflect very different colors from Earth’s green forests. The other image depicts a planetary system around a slightly hotter star than our Sun. In prior research, Carl Sagan Institute scientists have theorized that organisms could evolve biofluorescence to protect themselves from a more intense star.

Can we look for life in the clouds of other Earths? 🧵

I’m excited to share my new paper showing the first reflectance spectra of microorganisms living in Earth’s atmosphere.

Happy Halloween! ✨ 👻 🎃 Jack-o’-lanterns aren’t the only signs of life that glow in the dark. Some organisms on Earth do, too. Would a distant planet full of glow-in-the-dark aliens be detectable to our telescopes?
