   A diagram illustrating the different climate pathways Venus may have taken. (Constantinou et al., Nat. Astron., 2024) Venus bears many similarities to Earth. It has a similar size, a similar mass and density, and a similar mineral composition. But it's very different in ways that make a huge difference to habitability as we know it.

   1 day ago · A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbour was once much more like Earth than it is today. The researchers, from the University of Cambridge, studied the chemical composition of the Venusian atmosphere and inferred that its interior is too dry today for there ever to have been enough water for oceans ...

   Are Mars and Venus the same planet?

   • But their location is not all that they share. Just like Earth, Mars and Venus were made out of the same protoplanetary disc – a cloud of dust and gas that aligned around the Sun shortly after its formation – so they all have similar ages and materials. But after 4.6 billion years, they have become very different planets in many ways too.

   Why are Venus and Mars called planets?

   • Both planets get their names from Roman gods. Venus, the goddess of love and beauty, and Mars, the god of war. Even though they are Earth’s neighbors, both planets are outside the Solar system’s habitable zone, which means they can’t support liquid water on their surfaces. Both planets are uninhabitable to humans.

   Why is Venus different from Earth?

   • Temperature and pressure are what set Venus apart from Earth. Gilmore says these differences stem from a couple of factors: distance from the sun, and the internal heat of the planet itself. COMIC: Our sun was born with thousands of other stars. Where did they all go?
