Mars under the most advanced telescope in the world. “James Webb” took some pictures of the Red Planet

The James Webb Space Observatory continues to study the planets of the solar system. The telescope took several pictures of Mars, and they immediately allowed scientists to learn something new about the Red Planet, despite the fact that Mars is the most studied planet in our system, not counting the Earth.

In particular, the data from the NIRCam instrument made it possible to observe that the Hellas plain is darker than the surrounding areas during the hottest time of the day. One would think that this area is simply colder, but this is not the reason.

In fact, this is not a thermal effect. The Hellas Plain is at a lower altitude, and therefore there is a higher atmospheric pressure. This higher pressure leads to the suppression of thermal radiation in that particular wavelength range (4.1-4.4 µm) due to an effect called pressure expansion.

The bottom line is that the plain is a huge and very old impact crater. Because of this, the surface of the plain lies 9 km lower than the surrounding upland.

In addition, the telescope made it possible to obtain new data on the composition of the atmosphere of Mars and not only. A preliminary analysis of the spectrum shows a rich set of spectral features containing information about dust, ice clouds, what rocks are on the surface of the planet, and the composition of the atmosphere. The spectral characteristics of water, carbon dioxide and carbon monoxide are easily detected with the new telescope. This allows scientists to better work with exoplanet data. Scientists also expect that the data from James Webb will put an end to the debate about the presence of methane on Mars, which may be associated (but not necessarily) with the vital activity of organisms on the Red Planet right now.

500 fps in Overwatch 2 at 1440p and Ultra settings

A few hours before the release of Overwatch 2, Nvidia published an infographic in which they presented performance data for various current models of their video cards in the game. Of course, all the attention here is on the new GeForce RTX 40 (Ada Lovelace) models.

According to Nvidia official data, the GeForce RTX 4090 is the only model that, at a resolution of 2560 x 1440 pixels and ultra settings, can provide frame rates in excess of 500 fps. The result is, of course, impressive. And it is even more impressive against the background of the GeForce RTX 4080, which is one step lower with 16 GB of memory – this model is capable of only 368 fps under the same conditions. However, both of these models are suitable for 360-Hz monitors.

The performance gaps between the GeForce RTX 4080 12GB, RTX 3080 and RTX 3070 are not that big anymore, but still noticeable.

Nvidia recommends using the GeForce RTX 3080 Ti when playing games at Full HD resolutions above 360Hz, while the GeForce RTX 3060 can be used with Full HD monitors that support 144Hz.

This model was previously leaked under the Vienna name, but promotional materials show that the name has been changed. In the brand line, the novelty will be one step higher than the T-Rex 2.

At the moment, we can definitely talk about more than 150 sports modes, a dual-band GPS module, 4 GB of flash memory, a heart rate sensor with a pulse oximeter function, and an autonomy of up to 14 days.

As for the early data, the watch was credited with a titanium case, sapphire crystal, a 1.28-inch AMOLED screen with a resolution of 416 x 416 pixels and a peak brightness of 1000 cd / m2, as well as water protection (20 ATM). The announcement of new items is expected on October 13.

Foldable smartphone shipments to grow by almost 70 in 2022

Analyst firm IDC has unveiled its new study, according to which global shipments of foldable phones in 2022 will reach 13.5 million units. If we take into account that 8.1 million such devices were shipped in 2021, then the growth will be 66.6%. Experts note that the growth of the foldable smartphone market is largely due to the emergence of Samsung’s Flip and Fold lines. In particular, user interest is fueled by the recent launch of the new Galaxy Z Flip 4 and Fold 4, according to IDC.

In the future, sales of folding devices will also grow: for example, next year the supply of such models is expected to increase by 55.1%. In 2026, foldable smartphone shipments will reach 41.5 million units, with a compound annual growth rate of 38.7% between 2021 and 2026.

Analysts say the commercial market is ripe for the use of foldables as two-in-one devices that can replace both a phone and a tablet. But while the foldable phone market is expected to grow by almost 70 percent this year, they won’t go mainstream just yet. According to experts, such models will remain niche and flagship premium devices.
