Enceladus plumes might not come from an underground ocean

Published

Enceladus is Saturn’s icy moon. It has recently been projecting powerful plumes of steam, the real cause of which has not been identified. The scientists had issued thehypothesis that these plumes originated from a deep subsurface ocean. But the recent simulations make them explore other perspectives. Thus, the salt water spray would come from pouches of aqueous porridge.

Planetary scientist Jacob Buffo said they may not have broken through the entire icy lunar shell in order to reach the ocean. He adds that this discovery constitutes a step forward since this hidden ocean of Enceladus a perfect habitat for the search for life in the solar system.

In order to test their thesis, the researchers plan to collect sample of plumes. The tests carried out on these samples will make it possible to closer to the chemical composition of the underground ocean.

Plumes contain abundant salts

Scientists are intrigued by Enceladus since 2005 after it was revealed to them by NASA’s Cassini probe. The researchers wondered if the spray came from the icy surface of Enceladus, which is the place of friction from earthquakes that can melt the ice. The water resulting from the fusion of these blocks is released into space in the form of water vapour. But the latest information shows that an underground salt sea would be the source of the plumes.

According to physicist Colin Meyer, theone of the most convincing proofs was the fact that plumes contain salts. The first hypotheses based on earthquakes did not take this element into account. The new study suggests that salts in melted ice are left on the surface when water vapors are released into space.

Could Enceladus have harbored a form of life?

Meyer understood that pockets of meltwater in the ice shell could contain salts and other constituents. With the help of his colleagues, he applied computer simulations on the Sea of ​​Ice from the earth to Enceladus. Thus, they discovered that Enceladus could produce pockets of porridge inside its envelope and evacuate them into space.

This discovery does not explain the fact that Enceladus has no oceans or that its ocean is not habitable, the researchers said. The impacts that this find could have are colossal, especially in the context of search for life elsewhere than on Earth.

The days of Ethereum mining are numbered. Vitalik Butering told when the network will switch to the Proof-of-Stake algorithm

The days of Ethereum mining are numbered Vitalik Butering told

The transition of Ethereum to the Proof-of-Stake algorithm, instead of the current Proof-of-Work supported by miners, has been talked about for a long time, but so far this has not happened. However, Proof-of-Stake is on the way. This was stated by Vitalik Buterin himself.

The days of Ethereum mining are numbered.  Vitalik Butering told when the network will switch to the Proof-of-Stake algorithm

During the Shanghai summit, Buterin said that the transition of the Ethereum network to the Proof-of-Stake algorithm will take place in August. Previously, it was planned for the second quarter of this year (and before that it was postponed many times), but now a new date has been announced. In case of unforeseen circumstances, the update will be postponed for a month or two, but it is definitely not in the interests of the network to delay further implementation of Proof-of-Stake.

Thus, there is not much time left for cryptocurrency miners to mine ETH. There is an opinion that after the transition to the Proof-of-Stake algorithm, the cost of Ethereum may fall slightly, but then it will definitely increase. In the meantime, for 1 ETH they give less than $2,000.

I have an Android Galaxy Z Fold3 Bill Gates reveals

The former head of Microsoft does not use the company’s smartphones. Answering a question about his mobile device on the Reddit forum, Bill Gates told what kind of smartphone he uses.

I have an Android Galaxy Z Fold3 Bill Gates reveals

I have an Android Galaxy Z Fold3. I try different ones. With this screen, I can get by with a great laptop and phone and don’t need anything else.

Third-party sources, of course, emphasize that Gates could use the Microsoft Surface Duo 2, but, like the first generation, this device failed in sales and is inferior to Samsung’s foldable flagship on literally all fronts.

As for other smartphones or the laptop he chose, Gates, unfortunately, did not disclose the details.

Smart watches Google Pixel Watch can surprise you with the amount of memory: there will be more flash memory than in some smartphones

Smart watches Google Pixel Watch can surprise you with the

Google announced the smart watch ten days ago, but kept silent about the technical characteristics of the novelty. Therefore, details about the device have to be collected bit by bit. A previous leak said the watch would get Samsung’s rather old Exynos 9110 SoC, but the new data is encouraging: the Pixel Watch may have a fresher SoC.

Smart watches Google Pixel Watch can surprise you with the amount of memory: there will be more flash memory than in some smartphones

This scheme is not new, it has already been tested in a number of other wearable devices: a low-power SoC ensures that the device works for a long time with basic capabilities, and when all functions are supposed to be used to the maximum, a more powerful (and obviously more modern) hardware system is involved.

But even this is not interesting: Pixel Watch is credited with a lot of flash memory – as much as 32 GB. Such a volume for applications is clearly redundant, so it is suggested that Google will focus on the ability to download and store a large amount of music right on the watch. Which is good for sports. However, it will be possible to store podcasts right in the watch, for example. The amount of RAM will be “slightly more than the Galaxy Watch 4”. Samsung smartwatches have 1.5 GB of RAM, so it’s logical to assume 2 GB of RAM in Pixel Watch.

Finally, the Pixel Watch is said to be sensor-similar to the Fitbit Charge 5. This means that Google’s new product will provide the same vitals tracking capabilities. At a minimum, you can count on the monitoring of heart rate and SpO2, as a maximum – on the possibility of recording an ECG.

This concludes the new batch of details about the Google Pixel Watch. Recall that the novelty will go on sale in the fall.
