According to the Telegram channel Dva Majora, after covering a considerable distance, the Tu-22M3 approached its base, but in the end, due to the deteriorating condition of the aircraft, it was unable to continue the flight.
The report also highlighted the systematic tactics of Ukraine, alluding to traps set by Ukrainian forces for Russian aircraft.
Prior to this confirmation, Ukrainian Air Force Commander Mykola Oleshchuk announced on Telegram that Ukrainian air defense units, in coordination with the Main Intelligence Directorate of the Ministry of Defense of Ukraine, successfully destroyed a Tu-22M3 strategic bomber carrying Kh-22 cruise missiles. which Russia used to attack peaceful Ukrainian cities, writes Defense Blog.
The incident reportedly occurred while Russian bombers were carrying out missile strikes aimed at Ukraine.
The TU-22M3 is an upgrade of the Soviet TU-22 strategic bomber, which first flew in 1983. The M3 modernization increased the bomber’s range by a third, its maximum speed to Mach 2.05, and its payload to 1,700 kg. The aircraft also received a new navigation/attack radar and was also modified to launch Kh-32 missiles.
In the Ukrainian war, the TU-22M3 was used for the first time on April 15, 2022, during the bombing of Mariupol. At the end of December of the same year, one of the TU-22M3 was damaged during a drone attack at the Diaghilev Air Base, and in 2023 at the end of August, it was captured in flames after a drone attack on the Solciu air base.
According to Ukraine, one Tu-22M3 was destroyed and two were damaged in 2023. in August during an operation by the Ukrainian intelligence unit – but so far no such bomber has been shot down in flight.

Using emojis is useful for making passwords uncrackable
Whenever creating an account anywhere in the Internet world, the service instructs you to create a strong (hard to crack) password. Such passwords usually contain a number, a symbol or an uppercase letter, but hackers still manage to crack it.
Tech experts have suggested a method that would take hackers about 3,700 attempts to crack a password, and that is to add emoji to your password.
There are more than 3600 emojis in Unicode and using five emojis is equivalent to a normal password of 9 characters or using seven emojis is equivalent to a strong password of 13 characters.
Such a password can be almost impossible to guess and easier for people to remember than meaningless words and numbers.
Stan Kaminski of Casper Sky, a cybersecurity company that shares key password information, said in a blog post that there are a number of hacking tools and dictionaries for cracking passwords that contain combinations of words, numbers and common wildcard characters.
They said that when an attacker sees the leaked password database, your account will be protected with a hard password (using emojis equivalent to a phrase).
He said that using phrases with emoticons as passwords is a great way to do it.

Discovering the Largest Stellar-Mass Black Hole in the Milky Way Galaxy: Unexpected Findings in Astronomy
2024-04-18 05:00:05
A research paper by a team of astronomers claiming to have accidentally discovered the largest stellar-mass black hole ever detected in the Milky Way Galaxy has been published in the astronomical journal Astronomy & Astrophysics.announcementIt was done.
Stellar-mass black holes are formed by the gravitational collapse of a star, usually via a supernova explosion. It is much smaller than supermassive black holes such as Sgr A*, which is located at the center of our galaxy. Sagittarius A* has a mass about 4 million times that of the Sun, while the newly discovered stellar-mass black hole, Gaia BH3, has a mass about 33 times that of the Sun.
unexpected discovery
Gaia BH3 is about 2,000 light years away in the constellation Aquila, making it the second closest known black hole to Earth. Most of them are less than 10 times the mass of the Sun, and Cygnus X-1, the second-largest stellar-mass black hole in our galaxy, is only 21 times the mass of the Sun.
“No one expected that we would find a high-mass black hole lurking nearby, undetected until now,” said Pasquale Panuzzo, an astronomer at the Paris Observatory of the French National Center for Scientific Research (CNRS). He said, “This is a once-in-a-lifetime discovery in my research career.” Panuzzo is a member of Project Gaia, a collaborative research project that aims to create a detailed three-dimensional map of the galaxy.
companion
The research team discovered Gaia BH3 from observation data from the European Space Agency’s (ESA) Gaia astronomical observation satellite. Preparations were being made for large-scale data release to the scientific community, scheduled for 2025.
Data from the Gaia satellite detected an influence on the orbit of a companion star that forms a binary system with Gaia BH3. The observations were double-checked using data from the European Southern Observatory’s (ESO) giant telescope VLT, located in the Atacama Desert in Chile, South America.

metal-deficient star
The discovery of such massive stellar black holes provides evidence that black holes can form through the collapse of metal-poor stars, which contain few elements heavier than hydrogen and helium. In astronomy, elements heavier than hydrogen and helium (heavy elements) are collectively called “metals.” Gaia BH3’s companion star has been found to have extremely low metal content, suggesting that the star that collapsed to form Gaia BH3 was also metal-deficient.
Because metal-deficient stars lose relatively little mass during their lifetimes, they are thought to leave behind more material at the end of their lives, forming high-mass black holes.
The authors decided to publish their findings early so that other astronomers can quickly begin studying this exceptional black hole. It is hoped that this will help clarify whether Gaia BH3 draws in substances from its surroundings.
