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.
There are no two ways to say this - smartphones are boring and Mobile World Congress has exposed this. If the biggest news story coming out of Barcelona is the return of Nokia's feature phone, then we have a problem...
The Misfit Ray is a sleek and inconspicuous fitness tracker, which sacrifices accurate data for a fashionable design - perfect for the fashion conscious.
Google tried with balloons. Facebook has drones. Now, British mobile provider EE has joined the fight to provide rural communities with phone signal - using both high-flying balloons and drones.
A group of seven exoplanets have been found orbiting the star, known as Trappist-1, by NASA. This amazing discovery has raised hopes in the hunt for alien life and other planets for the human race to colonise.
It’s a common story - you access Facebook’s privacy settings and lock down your account, to prevent your data falling into the wrong hands. But how much of your activity, in spite of changing those settings, is still public? Well, a Belgian white hat hacker made the site ‘Stalkscan’ to find out.
Now that Snapchat Spectacles are available online, the sheen of vending machine-related exclusivity is now off. That makes this the perfect time to post a long term review of my own pair.
Global Gene Corp and GA4GH (Global Alliance for Genomics and Health) are delighted to announce the launch of ggINDIA, the first ever beacon for Indian genomics data. This Beacon joins those already on the Wellcome Genome Campus supplied by EMBL-EBI and the Wellcome Trust Sanger Institute. I will get the obvious question out the way - what on Earth is genomics data? Let's find out...
Struggling to sleep? You’re not alone, as 22% of Britons feel the same way. Luckily, research has found a cure - spending time outdoors away from artificial light sources, such as your smartphone or laptop. Doing this can reset your biological clock and help you sleep longer.
With the tenth anniversary of iPhone being this year, many of us are expecting a big redesign with new features - that is exactly what the “best Apple analyst on the planet” has said. Finally, late to the party, wireless charging will be coming to Apple’s smartphone this year.
When photography was invented in the early 1800s, it wasn’t long before people realised that you could develop a 3D image if you overlaid the same image at a slightly different angle. This gave birth to Victorian Stereoscopes, which was the first step the human race took towards 3D pictures, movies and Virtual Reality.
