Venus is the second closest planet to the Sun and one day it could have been very similar to ours, but today it has almost no water. A new study, presented by a team led by the University of Colorado in Boulder (USA), points to an explanation that has to do with hydrogen atoms escaping from its atmosphere.
Although Venus is almost the same size as Earth and has a similar composition, it bears little resemblance to our planet. The temperature on its surface, volcano coveris about 470 degrees, and the atmospheric density is almost one hundred times that of Earth, with clouds and sulfuric acid rain.
Researchers turned to computer simulations to try to explain why Venus became so dry, even though it is believed that billions of years ago, during its formation, it received as much water as our planet.
Today our neighboring planet has 100,000 times less water than Earth, said one of the signatories of the study Michael Chaffin, from the University of Colorado. Image: NASA
A molecule called HCO+
The research indicates that hydrogen atoms from Venus’ atmosphere are shot into space through a process known as dissociative recombination, causing the loss of about twice as much water per day compared to previous estimates.
The culprit for this water escape would be a molecule called HCO+ (an ion formed by one hydrogen atom, one carbon atom, and one oxygen atom) found high in the atmosphere of Venus.
HCO+ is constantly produced in the atmosphere, but individual ions do not survive long. Electrons from the atmosphere find these ions and recombine to split them into two.
In this process, hydrogen atoms disperse and may even escape into space, depriving Venus of one of the two components of water. In fact, previous research has already pointed to HCO+ as a possible cause of Marte would also lose much of its water.
The group calculated that the only way to explain the dry state of Venus was for the planet to harbor larger-than-expected volumes of HCO+ in its atmosphere.
The problem is that, until now, HCO+ has not been observed around Venus, but the reason may be that it has never been looked for, because the space missions that arrived there did not have the necessary instruments for these measurements.
Did a catastrophe evaporate the water?
Venus may have once looked almost identical to Earth, but at some point catastrophe struck and clouds of carbon dioxide in the atmosphere triggered the most powerful greenhouse effect in the solar system, raising the surface temperature. up to almost 500 degrees.
That process caused all the water to evaporate and most of it to be dispersed into space, but that evaporation cannot explain why it is so dry today or how it continues to lose water to space. That is the question that the current study tries to answer.
Yes (God, Nature)

Chatreey TK12-F Silent Mini PC: Efficient Heat Dissipation with Ribbed Casing
To dissipate heat efficiently, the computer uses its own ribbed casing.
The downside to most compact computers is noise, as small coolers are much louder than their larger counterparts. Chatreey decided to solve this problem by introducing the TK12-F silent mini PC. The device does not have a cooler and is cooled only by a case with fins for better heat dissipation. At the same time, the computer offers very powerful hardware and a wide set of connectors.
Chatreey TK12-F offers a choice of either Intel Core i7−1255U (10 cores and 12 threads up to 4.7 GHz, 7 nm with TDP 15 W) or Core i5−1235U (10 cores and 12 threads up to 4.4 GHz , 7 nm). with TDP 15 W) – both with Iris Xe graphics. In terms of performance in Cinebench 15 single-threaded / multi-threaded, the Core i7 gets 239/1400 points, and the Core i5 gets 214/1086 points, respectively. The maximum amount of RAM in the new product is 32 GB DDR4, and for storing files there is both a slot for an M.2 NVMe SSD and there is a place for a 2.5-inch SSD / HDD with a SATA connection.
Despite the fact that the machine body is a radiator, its dimensions are tight. At the same time, it easily accepts connection interfaces such as USB-A 3.2 Gen 2, four USB-A 2.0 connectors, two HDMI and a pair of gigabit Ethernet, one DisplayPort and Thunderbolt 4. For audio connection it has a 3.5 mm jack. , the Bluetooth 5.0 module is named, and for reliable Wi-Fi 6 operation there is a pair of external antennas.
Price and availability
Chatreey TK12-F available to buy on AliExpress at the following prices:
- Intel Core i5 – 1235U (without RAM and SSD) – 28,836 rubles;
- Intel Core i5 – 1235U (16/512 GB) – 36,888 rubles;
- Intel Core i5 – 1235U (32/1024 GB) – 44,579 rubles.
- Intel Core i7 – 1255U (without RAM and SSD) – 35,648 rubles;
- Intel Core i7 – 1255U (16/512 GB) – 43 701 rubles;
- Intel Core i7 – 1255U (32/1024 GB) – 51,392 rubles.
