Secrets of a dark planet: James Webb will help uncover the source of strange signals
The first super-Earth discovered by astronomers has been emitting strange signals for almost two decades, and scientists may finally have figured out why it’s happening.
A new study suggests that this “dark planet” periodically forms volcanoes, spewing hot gases that form an atmosphere, and then it disappears, leaving the planet “bare.” Testing this theory requires pointing the James Webb Space Telescope (JWST) at this strange exoplanet.
Planet 55 Cancri e is about eight times more massive than Earth and was discovered in 2004 about 40 light-years from Earth.
The planet is very close to its parent star, less than 2% of the distance between the Earth and the Sun, and completes an orbit in just 17 hours. This creates extremely extreme conditions on the planet that are still difficult to explain.
The most mysterious aspect of the planet is the nature of its transit signal. This is the light visible from Earth when 55 Cancri e passes in front of its star, creating a small eclipse, and also the light visible when the planet passes behind its star.
Sometimes, when 55 Cancri e passes behind its star, no visible signals come from the planet, but from time to time the planet emits a strong visible light signal. In the infrared range, the signal is always present, but its strength varies.
Observations of this infrared signal using the Spitzer Space Telescope revealed that the day side of the planet experiences exceptionally high temperatures, exceeding 2,427 degrees Celsius, while the night side has cooler, but still hellish, temperatures of around 1,127 degrees Celsius.
In the new study, the authors suggest that the planet’s proximity to its parent star causes it to emit gases, meaning the planet contains giant volcanoes and thermal vents that spew hot carbon-based elements into the atmosphere. But the planet cannot retain this atmosphere due to extremely extreme temperature conditions, and the gas is eventually blown away, leaving the planet “bare” until the process of gas emission resumes.
Researchers believe this variability in 55 Cancri e’s atmosphere may explain the strange transit signals. When a planet is in its atmosphereless phase, no visible light comes from the planet’s atmosphere because there is no atmosphere, but the planet’s hot surface still emits infrared light. When the atmosphere forms, visible light and all radiation from the surface appears as a transit signal.
Although this is just a hypothesis, JWST will be able to help test it. By measuring the pressure and temperature of a planet’s atmosphere, scientists can determine whether it always has an atmosphere.
In addition to the ultra-cheap Smart 8 HD smartphone, Infinix also presented a whole line of budget models: Hot 40.
It includes the junior model Hot 40i, basic Hot 40 and Hot 40 Pro. Pricing hasn’t been announced yet, but the company says they’ll all cost less than $200.
Hot 40 Pro, as expected, looks the most interesting. There is a camera with a resolution of 108 megapixels, a 120 Hz screen, and 8/128 or 8/256 GB of memory. The device is also equipped with a 5000 mAh battery with 33-watt charging, Helio G99 SoC and a 6.78-inch Full HD+ display.
The Hot 40 is similar to the older model, but it has a screen with a frame rate of 90 Hz, is based on the Helio G88 and a 50 MP camera. The remaining parameters are identical.
The younger model Hot 40i is more different. The heart here is the less productive SoC Unisoc T606, the basic amount of RAM is 4 GB, although there is also a version with 8 GB, the screen here has HD+ resolution with a diagonal of 6.56 inches and supports a frame rate of 90 Hz, and charging power is limited to 18 W. Other parameters are the same as Hot 40.
It is also worth noting that all models received IPS screens.

In 2024, Huawei will “rewrite industry history.” The company will release “advanced, innovative and revolutionary products”
For almost five years now, Huawei has been under strict American sanctions, and all this time the company has worked tirelessly. Now it may be time for a major push. At least the words of Yu Chengdong, CEO of Huawei’s consumer business group, indicate exactly that.
At Huawei’s annual reporting conference, Yu Chengdong promised to rewrite the history of the industry and announced completely new revolutionary devices. The top manager said the following verbatim: “When the time comes, you will see how we can rewrite the history of this industry. I hope to continue to exceed everyone’s expectations and do what others can’t even think of, or what they can’t do, or even what they don’t dare do.” And we were not talking about some distant future, but about 2024.
There are no specifics yet. But one of the breakthroughs could be the release of our own single-chip systems with 5G support – very well-established insiders are talking about this. Moreover, SMIC is rumored to be preparing to produce 5nm SoCs for Huawei. If this really happens, it can be called a breakthrough for the entire period of Huawei’s existence under sanctions. And next year, new, and far from trivial, cars are expected to be released on Huawei platforms and with the proprietary HarmonyOS operating system.

This ultra-cheap $75 smartphone offers a “premium” design and a 90Hz screen. Infinix Smart 8 HD unveiled
Infinix has announced the Smart 8 HD smartphone with a price of just $75. At the same time, the device is equipped much better than many smartphones priced at $100-120.
But it’s worth starting not even with this, but with design. As you can see, Infinix does not betray itself and even made an ultra-budget smartphone so that it stands out: the back cover seems to have a relief pattern. The company itself even uses the expression “premium design,” but this, of course, is on its conscience.
From a technical point of view, the device is not bad, and for such a price it is very good. It is based on the Unisoc T606 SoC, which scores about 240,000 points in AnTuTu 10. There is 3 GB of RAM, 64 GB of flash memory, a 13-megapixel main camera and a 5000 mAh battery. And the 6.6-inch screen with HD+ resolution also supports a frame rate of 90 Hz. In addition, there is an element that imitates the Dynamic Island of the iPhone.
It remains to add that the dimensions here are 164 x 75.6 x 8.5 mm with a weight of 184 g.
