A full-size model of the twin-engine reconnaissance and strike unmanned aerial vehicle "Sirius" created by the Kronstadt Group at the Kronstadt Group (Moscow), 26.02.2021. Image source: Ministry of Defence of the Russian Federation Manned aviation acts mainly as a strike weapon against targets detected by Sirius, noted in the company "Kronstadt" MOSCOW, February 4. /TASS/. The latest Russian heavy unmanned aerial vehicles (UAVs) "Sirius" will be able to work as part of reconnaissance and strike circuits together with manned aviation. This was reported to TASS in the press service of the company "Kronstadt". "The ability to interact with manned aviation means joint work as part of reconnaissance and strike circuits, where the complex with uaVs acts as a reconnaissance and an operational strike weapon against ground and surface objects detected by it. Manned aviation acts mainly as a strike weapon against targets detected by Sirius," the ...

Image Credit: spacex  Washington. February 3. INTERFAX – A falcon 9 heavy launch vehicle on Thursday successfully launched into orbit a batch of 49 mini-satellites designed to continue the deployment of the global Network of Internet coverage of the Starlink system, the developer of SpaceX said. "The withdrawal of 49 Starlink satellites has been confirmed," the report said. The launch was carried out at 13:13 on the east coast of the United States (at 21:13 Moscow time) from the launch complex 39A at the spaceport at Cape Canaveral in Florida. Liftoff! SpaceX's orbital constellation now consists of 2,089 spacecraft weighing 290 kg each. Currently, the company is the largest satellite operator in the world. About 15.5 minutes after the launch, 49 satellites separated from the second stage of the rocket in an elliptical transition orbit with an altitude of up to 340 km. After checking their performance by SpaceX engineers, the satellites using their own ion engines will ris...

  Employees of the European Southern Observatory  said  that they received images of the spiral galaxy NGC 7582, in the center of which is a supermassive black hole. The galaxy NGC 7582 is located 70 million light-years from Earth in the constellation Crane. In its core is a supermassive black hole.  The galactic core of NGC 7582 is supplied with energy by a black hole. In the process of this interaction, matter heats up and emits a huge amount of energy and powerful streams of particles into the surrounding space. The authors decided to find out what effect this process has on the entire galaxy. They looked at how the various ionized elements are distributed in it. In the image to the right, oxygen, nitrogen, and hydrogen are shown in blue, green, and red, respectively. The red ones are areas of high star formation activity, the dominant blue areas show the cone-shaped material that comes from the active galactic nucleus. The image on the left shows the same area. ...

On February 8, the asteroid 2007 UY1 will approach the Earth, the diameter of which is 150 meters. This follows from data released by the US National Aeronautics and Space Administration (NASA). It should be noted that according to the international rules of the game of football, the maximum length of the sideline of the field cannot exceed 120 meters, and the goal line - 90 meters. Thus, the dimensions of the celestial body are larger than the dimensions of a football field. The asteroid, discovered in 2007, will pass Earth at a minimum distance of 5.3 million km. According to scientists, the probability of UY1 colliding with the Earth is extremely small.

      Credit: © globallookpress/NASA SpaceX's numerous Starlink satellites make it difficult for astronomers to capture high-quality images and may interfere with the search for potentially dangerous asteroids. This is reported in a study in the scientific journal Astrophysical Journal Letters. It is noted that scientists considered the influence of Starlink satellites on about 300 thousand images that were taken at the Palomar Observatory in Southern California. From November 2019 to September 2021, there was a 35-fold increase in the number of corrupted images. "For comparison: in 2019, 0.5% of twilight images were affected, and now this figure has increased to 20%," explained Przemek Mroz, lead author of the study. University of Washington astronomer Eric Bellm pointed out that reflected streaks of sunlight can complicate the search for potentially dangerous asteroids. "There's definitely a kind of planetary defense aspect here," he said. A NASA spokesman...

California chemists found that cyanide could act as a catalyst in the reactions of the synthesis of organic compounds from carbon dioxide on the early Earth. The study not only allows you to take a fresh look at the origin of life on our planet, but can also help in the search for life in other worlds. Perhaps this is what our planet looked like four billion years ago – a pale orange dot / ©NASA / Goddard Space Flight Center / Francis Reddy Yesterday,   a chemical compound known as cyanide (although it would be more correct to talk about a group of substances - cyanides containing the CN group) is associated by many with a very toxic colorless gas, a deadly poison and even chemical weapons. Indeed, many cyanides are toxic. Cyanides, as well as their derivatives, were used during the Second World War as a chemical warfare agent, and they still help in the fight against many pests: mice, rats, coyotes, opossums, ants. However, it seems that cyanide can not only bring death, but ...
