A new study into the history of Venus suggests the planet may have been suitable for life - potentially having huge oceans and green land just like Earth.
As the second planet from the sun, you may think of Venus as merely a hellish location with 900-degree surface temperatures and an atmosphere thicker than Earth.
But it turns out the planet may have had a liquid water ocean and habitable temperatures.
Climate models from NASA Goddard Institute for Space Studies in New York suggest that Venus was able to keep a source of water for 2 billion years – even though it’s a third closer to the sun than Earth.
That’s cool… How did they find this out?
Well, it’s all about the rotation of the planet and topography. These play important parts in the surface temperature and moisture - if a planet that close to the sun spins slower, it will become dryer and hotter (obvious enough).
In its past, Venus would have spun faster. And as climate scientist, Michael Way wrote in the paper published in Geophysical Research Letters if Venus rotated slower than about 16 Earth days, temperatures could be more moderate.
And even with 46-70% more solar radiation
Today, Venus is the solar system’s slowest spinning rock, rotating once every 243 Earth days.
But even at that speed, the planet could have been liveable until at least 715 million years ago.
So what does this mean for us?
This study breathes new life into looking for life beyond Earth. Not just if there are live aliens, but for even looking for the faintest evolutionary paths of extinct species.
The results of their work suggest that warm rocky planets like this one have the capability to retain significant water, even if they are closer to the sun.
"The inner edge (of a star's habitable zone) should, therefore, be considered a transition region in which the probability of habitability gradually decreases inward rather than a strict boundary separating completely different regimes," Way and colleagues concluded.
iPhone users - chances are you've received a calendar invite to "$19.99 Ray-Ban Sunglasses," or a "50%-off Ugg Boot" sale. Now while you may want to clear your calendar and take advantage of these incredible prices, unfortunately, they're fake. Here's how to get rid of them.
What happens in Vegas gets blogged about in January… Extremely thrilled to announce that New Rising Media is making the trip out to cover CES for the first time ever. But this isn’t just any CES, it’s the 50th anniversary of this legendary technology show.
Probably the most requested Netflix feature has now become a reality. In their new update, you can now download movies and TV shows for offline viewing.
People who signed that petition – you’re too late. The Investigatory Powers Act has just been given Royal Assent, meaning that UK Government is soon to become one of the most advanced surveillance states on the planet.
Thanks to a petition with over 120,000 signatures, the Investigatory Powers Bill – Britain’s new surveillance plans – could soon be repealed.
The Autumn Statement may have distracted you from this, but The Investigatory Powers Bill is now as good as passed, with the Digital Economy Bill shortly behind.
People across the globe are returning their Galaxy Note 7 mobiles to Samsung in exchange for apology rewards, to try to put out the fire on their reputation. But which country is getting the best deal? We took a look worldwide and ranked the company’s responses from best to worst.
As per the Autumn Statement, UK Government is set to invest billions into 5G, connecting more homes to fibre broadband and developing the infrastructure needed for driverless cars. But is all of this a smokescreen for the unprecedented surveillance powers they are about to get?
Someone is using former Lostprophets singer and convicted paedophile Ian Watkins’ Twitter account to promote new music - even though he is currently serving 35 years behind bars for his crimes.
While we can create computers that behave like brains, conventional circuitry means they will never perform as quickly as the sophisticated human neural network.
But Princeton researchers may have just solved this future and paved the future for this big area of research - creating the world’s first Light-based Neural Network.
