What caused the spiral anomaly in the sky over Norway in 2009?

On December 9, 2009, an intercontinental ballistic missile RSM-56 "Bulava" was launched from a submarine missile carrier in the White Sea. Its first two stages worked normally, but a technical failure occurred at the third stage. On the same night, the Norwegians saw in the sky an unusual blue spiral cloud with a white rotating spiral at the end. Presumably, this was the observed result of the failed test.

Random interesting fact from the Great Encyclopedia:

What animal can carry out the process of photosynthesis?

Not only plants can carry out the process of photosynthesis. The sea slug Elysia chlorotica lives on glucose obtained from the chloroplasts of the algae Vaucheria litorea. The slug does this by assimilating these chloroplasts into the cells of the digestive tract. After that, the process of photosynthesis begins - the slug genome encodes the proteins necessary for chloroplasts for this process, and in return receives synthesized glucose.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Lenovo ThinkStation PX, P7 and P5 workstations 25.03.2023

Lenovo has announced the release of the ThinkStation PX, P7 and P5 workstations. When designing them, Lenovo collaborated with Aston Martin.

The collaboration focused on capturing Lenovo's signature red design, delivering the best possible performance, and expanding customization options. In particular, the 3D body grille is inspired by the iconic DBS Grand Tour.

All three new workstations feature a modular design with front drive access for ease of service and upgrade flexibility.

The devices feature the latest Intel processors with up to 120 cores and support for professional NVIDIA RTX GPUs. In particular, the 4th generation Intel Xeon Scalable and NVIDIA RTX 6000 Ada Generation can be installed in top models. Can be installed

The workstations feature a new chassis design, an improved cooling system, and a baseboard management controller (BMC) for remote system monitoring.

The new workstations will be available from May 2023.
