The Chinese want to find a new Earth. The Closeby Habitable Exoplanet Survey project should make it possible to find planets very similar to ours

Chinese astronomers want to seriously take up the search for a twin of our Earth.

A group of scientists has been working on a project for 10 years, within the framework of which a special telescope can be built in a few years to search for Earth-like exoplanets in the part of the Universe closest to us.

The Chinese want to find a new Earth.  The Closeby Habitable Exoplanet Survey project should make it possible to find planets very similar to ours

The scientists of the Closeby Habitable Exoplanet Survey project want to concentrate on the search for exoplanets that are very similar in their main parameters and potentially suitable for life. In particular, they are interested in rocky planets of various sizes, including the so-called super-Earths, located in the orbit of sun-like stars in the habitable zone.

At the moment, astronomers around the world have already discovered quite a few exoplanets that meet most of the criteria, except for one very important one. They usually revolve around red dwarfs, and such stars stand out for their activity. Flares on such stars are many times greater than flares on the Sun, and at the same time they happen much more often. Under such conditions, life on the planet is much less likely to originate and develop.

The Closeby Habitable Exoplanet Survey is a mission to search for exoplanets around stars within 32 light-years of us. In total, about 100 such stars are known.

An important feature of the mission is the method of detecting exoplanets. The lion’s share of the planets discovered to date outside the solar system have been found by the transit method. Its essence lies in the fact that the presence of a planet can be determined by a short-term and slight decrease in the luminosity of a star. If it is a planet, this behavior of the star will be repeated. But for such a method, it is necessary that the observed stellar system is located edge to us. Of course, this leads to the fact that exoplanets are not found in most of the stars by the transit method.

Chinese scientists want to use the astrometry method, which is far from new, but has recently been used to search for exoplanets. The essence of the method lies in the fact that a planet in the orbit of a star gravitationally affects the star, slightly, but still affecting its movement. Modern technologies allow fixing such fluctuations. But scientists from the Closeby Habitable Exoplanet Survey project have achieved a breakthrough in this area over the years thanks to laser metrology in the focal plane. As a result, the measurement accuracy is an order of magnitude superior to that of the best astrometric instruments at the moment.

The Closeby Habitable Exoplanet Survey is yet to be approved. If it gets the green light, the team hopes to complete the telescope within five years. It will be placed at the Lagrange point L2 of the Sun-Earth system. The latest James Webb telescope is also located there.

12 million kilometers without changing the battery with zero risk

This week, BYD said in an investor communication that BYD Blade’s state-of-the-art battery packs can be charged and discharged more than 3,000 times. This allows you to cover 1.2 million kilometers without changing batteries.

BYD previously said its new BYD Blade vehicle battery will be a game-changer and usher in a new era of safety and performance for the electric vehicle industry.

In last year’s ranking of global battery manufacturers, BYD’s total installed battery capacity in electric vehicles reached 26.3 GWh. This allowed BYD to take the fourth place in the world with a market share of 8.8%.

Today, all BYD vehicles powered by new energy sources are equipped with BYD Blade batteries. Sales of all models such as Han, Tang, Song and Dolphin have exceeded 10,000 units in China alone.

In addition, the batteries have passed numerous tests, which have confirmed that they do not suffer from the problem of spontaneous combustion, even if the shell and geometry are damaged.

It will replace the Passat Volkswagen ID introduced AERO

Volkswagen introduced the ID sedan. AERO, which is built on the pure electric MEB platform. In addition, the dimensions and technical parameters were disclosed.

The car received a body with a drag coefficient of only 0.23Cd. Volkswagen ID. AERO is positioned as a mid-size sedan, its length, width and height are 4975, 189 and 1528 mm, respectively. Thanks to the advantages of a purely electric platform, its wheelbase reaches almost 3 m (2966 mm). According to Volkswagen’s official statement, it has an interior space comparable to the Phaeton.

Volkswagen ID. AERO uses a new interior design. The car uses a lot of straight lines. The LCD instrument panel is hidden in the center console, it also received a large floating center screen, while the car has almost no physical buttons.

Hidden under the floor of the sedan is a lithium-ion battery with a capacity of 77 kWh, which provides a range of up to 620 km on the WLTP cycle. 150 kW fast charging will also be supported.

It is often said that there is not enough chips

Japan’s largest semiconductor makers, from Toshiba to Sony, have warned that a shortage of engineers is threatening the government’s efforts to revive the domestic chip industry.

The expected labor crisis comes as Japan works to increase investment in the semiconductor sector as part of efforts to bolster its economic security amid the chip shortage caused by the Covid-19 pandemic.

In an address to the Ministry of Economy, Trade and Industry last month, the electronics industry group said that over the next few years, Japan has the best chance of regaining its position in the semiconductor market.

“It is often said that there is not enough chips, but most of all, engineers are missing.”  Japan's largest chip makers face shortage of specialists

The Japan Electronics and Information Technology Manufacturers Association said the sector’s success depends on attracting enough people to innovate and run chip factories. It is estimated that eight major manufacturers will need to hire about 35,000 engineers over the next 10 years to keep up with the pace of investment.

“It is often said that there is not enough chips, but most of all, there is not enough engineers,” said Hideki Wakabayashi, a professor at the University of Tokyo and head of the policy proposal task force at the JEITA Semiconductor Committee.

To support innovation and search for potential employees, Toshiba, Sony and other companies are collaborating with the best scientific departments across the country and investing additional resources in chip research and recruitment.
