Black holes many times larger than imagined
The time has come for astronauts to change the scope of their expectations about black holes. According to the New York Times, a team of international researchers has come to the conclusion that the size of one of the first black hole inventions, Seasonus X-1, is actually much larger than it is thought.
The binary system-based black hole was previously thought to have only 15 solar masses, but is now believed to be 21 solar masses.
While this may not seem very important compared to the supermassive black holes of millions or even billions of solar masses, it is time to change our perception of black holes.
The research team also found that the size of a black hole measured by X-rays was much larger than that found by the laser interferometer Gravitational-Web Observatory (LIGO).
NASA rover landed successfully on Mars
Called the state-of-the-art man-made astrobiology lab sent into space, the Perseverance Rover has successfully landed on Mars. The US space agency NASA's rover completed the landing at 3pm Bangladesh time on Thursday after a long seven-month journey.
The rover landed in a huge hole near the equator of Mars. Scientists have named the hole Jejero. The rover will try to find out if life ever existed on Mars, NASA said.
The six-wheeled Mars rover will orbit Mars for at least two years. There will be excavation of stones and collection of samples and information.
Shortly after landing, Perseverance sent several black and white images from the surface of Mars. In one of them, the shadow of the rover can be seen on the rocky surface of Mars. NASA has released a photo taken by Perseverance.
Meanwhile, after the rover landed on Mars, NASA workers were overjoyed. U.S. President Joe Biden observed the landing of the rover and congratulated those concerned.
Facebook stopped showing news in Australia
Facebook has blocked access to news content in Australia. The Facebook pages of the country's media are not visible even from outside Australia.

The Australian government has said the move would jeopardize Facebook's legitimacy.
The BBC's dramatic move has raised concerns among Australians about access to vital information, the BBC reported.
Residents of Australia woke up on Thursday morning to find there was no news content on their news feed, Reuters reported. They can't even see the Facebook page of any local or international media.

NASA's Mars rover Perseverance has successfully landed on Mars
Initially, NASA scientists thought there was no damage to Perseverance and would soon launch an "expedition" to Mars.
Perseverance entered the atmosphere of Mars this week after a journey of about seven months. Mars is able to touch the ground about 2040 million kilometers away from the earth.
Earlier, JPL's landing scientist Al Chen described the last 7 minutes of landing as the most risky and frightening. "Perseverance includes an six-wheeled search vehicle," he said. The vehicle has all the technical equipment needed to take pictures of the surface of Mars, analyze the nature of the soil, and send those pictures and information. The vehicle has been sent in a 'capsule' with the spacecraft to avoid any damage during the high-speed collision on the ground. After reaching the atmosphere of Mars. In the last 7 minutes, the vehicle-along with the capsule will crash and slowly stop at one place. This is the scariest and most complicated time.
However, the scientists said that they have been able to cope with the shock. After their expectation, the capsule will be opened and the 6-wheeler will come out from inside and start its search. Now NASA scientists are waiting for him.

Satellite of the United Arab Emirates in the orbit of Mars
The UAE's satellite has been successfully replaced in Mars orbit. Through this, the United Arab Emirates reached Mars as the fifth country after the United States, Russia, European Union and India.
The UAE took over the 200 million project called Hope in an attempt to reach Mars. The satellite launched the Mitsubishi H-2A rocket from the Tanegashima Space Center in Japan last July. The mission took about seven months to reach the destination, which both China and the United States were able to complete a little ahead of schedule.
The satellite will orbit around the red eclipse and monitor the environment. The main goal of the mission is to know the weather on Mars accurately.
The project also includes information on why Mars emits hydrogen and oxygen, how dust storms are created, and the global weather cycle.
