Earth, Mars and Venus all looked pretty similar when they first formed. Today, Mars is dry, cold, and dusty; Venus has a hot, crushing atmosphere. Why did these sibling planets turn out so different?

Data from an old NASA spacecraft reveals a volcano erupted on the surface of Venus in 1991, a new study in Science says.

The two brightest planets in Earth's night sky are millions of miles apart. But due to an astronomical quirk, they appear to be engaging in a cosmic dance tonight. Now that's a moment of awe.

To reach the innermost planet in our solar system, this European space probe needs a little help from the gravity of Venus.

The two space probes will study Venus, a scorching hot world that may have once been like Earth. NASA chose the Venus missions over other candidates, such as trips to the moons of Jupiter and Neptune.

Scientists have found a gas associated with living organisms in a region of Venus' atmosphere. They can't figure out how it got there if it didn't come from life.
