Seventeenth moon of Jupiter

20.10.2000

We have already become accustomed to the fact that new satellites of the planets are discovered by automatic interplanetary probes or a space telescope. But it turns out that even today it is possible to make such a discovery with the help of a relatively small telescope standing on Earth.

For the first time in 25 years, a new moon has been discovered around Jupiter. Its diameter is only five kilometers, it was discovered by American astronomers using a telescope with a diameter of 92 centimeters installed at the Kitt Peak Observatory 79 years ago. The new satellite, which does not yet have a name, is located at a distance of about 24 million kilometers from Jupiter and completes its revolution around the planet in about two Earth years.

Thus, the total number of known satellites of Jupiter has now reached seventeen (the record in the solar system is held by Uranus, it has 20 satellites). Recall that the first four moons of Jupiter were discovered by Galileo in January 1610.

Perhaps in February next year, the automatic probe "Galileo" will be able to obtain more detailed data on the new satellite.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Huawei Tag Item Tracker 09.07.2022

Huawei has announced its first device designed to find forgotten or lost things: the novelty is called Huawei Tag.

The tracker supports Bluetooth wireless technology and NFC technology. Pairing is allowed only with smartphones running the proprietary HarmonyOS 2.0 operating system, for example, with the new Huawei Nova 10 and Nova 10 Pro devices.

The search for lost items is carried out through the Huawei Find network. The integrated buzzer is capable of beeping up to 92 dB. Location information is transmitted in encrypted form.

The product is enclosed in a case with dimensions of only 32,0 x 31,2 x 5,6 mm, and the weight is 6 g. IP67 protection against moisture and dust is implemented: the tracker is not afraid of diving under water to a depth of one and a half meters. A single CR2032 battery will last for more than a year of use.

The Huawei Tag costs $15 and the four-piece set costs $45.
