      Yeah they picked up the same reading on Venus which was later disproved. The headline is also somewhat misleading in that this planet is 9 times larger than earth (not sure what it’s mass is) so it wouldn’t accommodate humans but still it would be incredible to reconfirm results

        A planet 9 times the size of earth could still potentially host human life, we’d need to live high up in the sky so the gravity would be lower, but it’s possible

            Gravity becomes lower at higher altitudes, or what do you mean?

              The bigger aplanet, the further away its surface from its center of mass, which decreases gravity. A planet’s surface gravity is mostly affected by its mass and density. This is why Saturn, despite being much bigger than Earth, still have roughly the same surface garvity.

              The bigger a planet, the further away its surface is from its center of mass, which will decreases the force of gravity. A bigger planet does not equates to higher surface gravity, it’s a planet mass and density that mostly dictates this.

      Yes.

      Phosphene was thought to be found on Venus which can be produced by life or under conditions of a gas giant. However, the results are disputed.

      Methane has been detected on Mars but results can be explained by non-life processes.
