Second solar eclipse of the year on October 25

২৫ অক্টোবর এ বছরের দ্বিতীয় সূর্যগ্রহণ হবে। গ্রহণ হবে মোট ৪ ঘণ্টা ৩ মিনিট। পঞ্জিকা অনুযায়ী সূর্য গ্রহণ ২৫ অক্টোবর বিকাল চারটা থেকে। শেষ হবে রাত আটটা তিন মিনিটে।  এর আগে এ বছরে ৩০ এপ্রিল বছরের প্রথম সূর্যগ্রহণ হয়। চলতি বছরের উভয় সূর্যগ্রহণই আংশিক গ্রহণ।

বাংলাদেশ থেকে এই গ্রহণ আশিংক দেখা যাবে। সূর্য, পৃথিবী এবং চন্দ্র একই সরল রেখাতে  যখন অবস্থান নেয় তখন সূর্যগ্রহণের সৃষ্টি হয়।

জ্যোতিষ বিজ্ঞানীরা জানান, চন্দ্রগ্রহণের চেয়ে সূর্যগ্রহণ বেশি হয়।

সূর্যগ্রহণ খালি চোখে দেখা উচিত না। সূর্যগ্রহণের সময় খালি চোখে সূর্যের দিকে তাকানো চোখের জন্য মারাত্মক ক্ষতিকর।  সূর্যগ্রহণ দেখতে হয় টেলিস্কোপ বা সোলার ফিল্টার দিয়ে।




China's new initiative to prevent asteroids from hitting Earth

The asteroid that has come to Earth is the headline of the news, which has recently been successfully tested by the US space agency NASA to stop these asteroids.

The challenge of US space scientists China's National Space Agency or CNSA is planning to do a kinetic impact test.

China has decided to develop its own technology to destroy the asteroid that is coming towards Earth at a great speed, CNSA plans to conduct a Kinetic Impactor test to change the course of a potentially dangerous asteroid.

CNS Assistant Director of China's television channel U Yanhua said, "We are preparing a draft plan to protect the world through technical research to deal with the potential dangers created by asteroids close to Earth."

China is also developing a combined asteroid sample-return mission, which is said to target the ‘Kamo Oleo’ to provide samples to Earth. This small asteroid is known as a Nether Earth object. China's 14th Five Year Plan is to end the mission, if all goes well, China will do so by 2025.




Elon Musk reiterates his intention to buy Twitter

US billionaire Elon Musk has returned to the decision to buy Twitter, a report that wrote to Twitter amid legal complications that the US billionaire will spend $54.20 per share. Bloomberg is releasing this news on Tuesday. Twitter shares rose 12.7 percent to US$47.93 before trading ceased for the second time.

In April this year, Elon Musk announced the purchase of Twitter for 44 billion US dollars, which later backed away from his decision, saying that the number of bots on Twitter is more than a 100 times the number, he said, and he said he was withdrawing from the decision.

According to Twitter, the number of bots on their platform is less than 5 percent of the total number of customers, but Elon Musk claimed that the number of bots is more than a few times.

The report released on Tuesday said that Elon Musk has sent a letter to the Twitter deal, which has already given the green signal to the original price.

The dispute between Elon Musk and Twitter has already been held in court, and the advertiser has misinformed the advertiser, who is wrong in the number of these bots.

However, legal experts believe that Elon Musk will face a tough challenge to convince the judge in this case.




NASA intercepts asteroid heading towards Earth

A destructive asteroid is coming towards the Earth. Such news often makes headlines. But the reader is not moved by this news. Because, asteroids in space often run into each other. Some of them hit the Earth. But what if the asteroid that is coming can be intercepted before it hits the Earth? Surely it is beneficial for humanity. Such an incident has been done by the American space research agency NASA. The American space research center NASA has conducted an experiment to save the world from asteroids in the future.

Their Dart spacecraft was launched 10 months ago to target an asteroid. At 11:14 p.m. (GMT), the spacecraft crashed into the asteroid. "We have entered a new era. An era where we will have the ability to protect ourselves. No dangerous asteroid will be able to hit us," said Lori Glaze, director of NASA's Planetary Science Division.

Live footage from the spacecraft and the response from NASA's ground control team was broadcast live. The camera captured a close-up of the asteroid just seconds before the collision. The spacecraft hit the asteroid at speeds of 14,000 miles per hour (22,500 kilometers per hour). This is the first time such an experiment has been conducted. Now scientists will examine the results.

A few weeks ago, a small satellite, LysiaCube, broke away from DART. It passed close enough to take pictures of the asteroid after the spacecraft crashed into it.

The collision scattered rocks and other debris. Glaze said, "This is where science begins. Did the asteroid change its trajectory?" The mission cost $325 million. This is the first attempt to change the position of something in space using kinetic energy.

Dress rehearsal

There is no asteroid, comet or any other object near the Earth yet. According to NASA, there is nothing that can collide with the Earth. However, scientists warn that more than one such object may be seen. Scientists now have the option that when such an asteroid or comet comes, scientists can change its trajectory.

The second option is to try to break them up in space, so that the impact of the smaller pieces will not be as severe.




9-year-old catches Tim Cook's eye by creating iPhone app

The Indian girl has been named by the 9-year-old Indian Indian Met Hahana Muhammad Rafiq, who is the youngest IOS Developer who has the name of the 9-year-old Indian resident of India, who is the only 9-year-old man, who has been designed by the iOS app for iPhone.

There is a reason behind this claim. The reason behind this claim is that this girl has created a story telling app called ‘Hannas’ based on her own name. With this app, parents can record stories for children. It is being said that Apple CEO Tim Cook was aware of the details of his work in the email.

It's also known how Hana's head came up to make an app that would have a suitable story for kids or children.

After watching a documentary, the thought of creating this app came to the head of the attack. Then he did the impossible pursuits. In many cases, it is seen that children who listen to the story easily fall asleep. But all the parents, it is not possible for the parents to sit in front of the child and tell the story.

In most cases, the obstacles are busy. This time, if there is an iPhone, the parents can accompany the child using the app created by the iOS version and not being with the child. A suitable story for children can be recorded.




Jupiter is coming close to Earth after 70 years

There are many games going on in the universe, coming to the planets and going away; The world's largest planet Jupiter is coming closer to Earth.

Scientists think that such an event is rare in the history of the last 70 years.
The space scientists know that this rare event is going to happen on September 26. Jupiter is coming closer to Earth on the same day, and Jupiter will be seen in the sky all night. The Sun and Jupiter will be on the same side, as opposed to the Earth, and Jupiter will rise in the east, as it is, and set in the west, as it is, as the Sun.

NASA said in a statement that as Jupiter will come very close to Earth on September 26, it will look much clearer and brighter than Earth, which is quite rare.

NASA said that Jupiter will be the most shining in the other planets and stars in the sky except the Moon. But Jupiter will not be seen from Earth with the naked eye, scientists say, if you want to see the planet, you have to take the help of a telescope. In addition to the main planet through a good telescope, three or four satellites of Jupiter can also be seen in this same way.

It is known that the distance between Earth and Jupiter will be reduced to 58 million kilometers on September 26.

The distance from Earth to Jupiter is 592.69 milligrams, but the distance from Earth to Jupiter will be at least 365 millimeters from Earth on September 26. The phenomenon of Jupiter is close to Earth as the Earth's Marshal Space Flight Center study astronomer Adam Kobelski.

He said, “If you use the modern band binoculars, you can see the day from the surface of the earth.”

The largest planet in the solar system is the fifth in terms of distance from the Sun, the largest in the solar system and in terms of size. Jupiter is 1,42,800 km in diameter, about 1,300 times larger than Earth, which is about 77.8 million kilometers from the Sun.

The mass of the planets in the solar system except Jupiter is two and a half times the mass of Jupiter, the primary element of Jupiter is hydrogen and a small amount of helium.
