In honor of the live-action 'Lilo & Stitch', we look back at 12 extra-terrestrials who came in peace.
On the surface (you're welcome for the joke), Venus is not even close to being hospitable to life. But that's not the end of the story.

How Likely Is Life on Mars?
Mars is by far the most Earth-like planet in the solar system…but that’s not saying much.
Missions to Mars with the Starship Could Only Take Three Months
Mars has received considerable attention in the past few decades, thanks to the many robotic missions exploring it to learn more about its past. NASA and China plan to send astronauts/taikonauts there in the coming decades, and commercial space companies like SpaceX hope to send passengers there sooner. This presents several significant challenges, one of the greatest being the lengthy transit times involved. Using conventional propulsion and low-energy trajectories, it takes 6 to 9 months for crewed spacecraft to reach Mars.

What's at the center of Mars? Maybe the stench of rotten eggs
Mars' core formed within just a few million years, scientists say compared to the hundreds of millions or even billions of years that it took for Earth's core to form — it also might smell like rotten eggs.
Future Telescopes Could Detect Life Managing their Planet Atmospheres
The challenge in the search for habitable worlds is clear. We need to be able to identify habitable worlds and distinguish between biotic and abiotic processes. Ideally, scientists would do this on entire populations of exoplanets rather than on a case-by-case basis. Exoplanets' natural thermostats might provide a way of doing this.
