Space probes have never found any evidence of life on the planet's surface but this time they're looking at the gasses surrounding Venus.
Tiny life forms
Researchers say there's lots of water in the clouds around the planet, and that would make it a good home for tiny life forms like microbes.
The people studying Venus also believe the temperature on the planet used to be a lot cooler and there could have been oceans there.
But other scientists argue the research doesn't prove bugs actually live on Venus and they still think life on Earth's closest neighbour is impossible.
