The Earth should be safe (and habitable) for a few billions of years, but we still need to worry about the impact now of just a few degrees of global warming.
A severe climate change event on Venus may have transformed an Earth-like climate to the current uninhabitable-to-humans state.
The Arecibo radio telescope has collapsed but its amazing discoveries will live on.
Unlike our hellish neighbour Venus, Earth was far enough from the Sun for liquid water to form and create a more hospitable environment for life.
Considering what we know about the key ingredients for life's formation on Earth, here are three explanations for how this process may have occurred on our sister planet.
News that Venus may harbor life has swept the globe. So how do we find out for sure? A planetary scientist explains what's next.
The clouds of Venus may harbour alien life. But where else?
The discovery of phosphine in the acidic clouds of Venus can't be explained by any known chemical or geological processes.
Scientists don't claim to have evidence of life on Venus but they have ruled out pretty much everything else.
Many people are still upset that Pluto was demoted from being a planet. But definitions of various celestial objects are fairly fluid. So whether it is an asteroid or moon or planet is up for debate.
This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
The upper atmosphere of Venus is the most Earth-like extra-terrestrial location in the solar system. It could even host life.
The five planets visible to the naked eye since ancient times are putting on a dazzling display this month, in a night-sky dance along with the Moon.
The longest lunar eclipse this century, and other special features such as Mars looking spectacular will be seen.
All five five planets visible to the naked-eye are on show in the night skies over Australia, and a Blood Moon on the way too.
No matter how cold it is, you're lucky you don't live on Venus.
Researchers recently discovered the hottest planet known. But which one is the coldest? And the biggest?
The planet is more similar to Earth than any other – except when it comes to supporting life.
Earth is a relatively dry planet compared to some of the other ocean worlds in our Solar system. Life needs water so what about life on these other places?
Over the last 20 years, advances in the field of exoplanet discovery have excited the imaginations of scientists and enthusiasts alike. But we're in position to know yet whether a planet is habitable.
