The Hubble Space Telescope observed an unprecedented distance star, and it was called “Erendel” because its light took 12.9 billion years to reach Earth.

Scientists estimate that the size of the star competing with the largest known stars is at least fifty times greater than that of the Sun, and it is millions of times brighter.

As for the previous star, it set records, it was tracked by the Hubble telescope in 2018, but it was in the universe four billion years ago, only about 900 million years after “Erdel” after the Big Bang. According to experts.

The discovery was published Wednesday in the prestigious scientific journal Nature.

Brian Welch, a leading reporting editor at Johns Hopkins University in Baltimore, said in a statement that “we did not initially believe the telescope’s.

Welch took on the task of naming the star and named it “Erindl”, meaning “Morning Star” in Old English.

The researcher explained that this star “has been around for so long that it could not have been made of objects like the stars around us today.”

He added, “Studying this star will open the way for us to learn more about a particular time period in the universe, but it has led to everything we know today.”

So this star will be the main target of the new “James Webb” space telescope, whose capabilities are currently being tested in space. The European Space Agency, which operates the telescope in conjunction with US space agency NASA, has said James Webb will monitor Erendle from this year onwards.

Like the sound that disappears when an object moves away, the wave of light expands and travels from the apparent frequency to the naked eye and then to infrared radiation.
Unlike the Hubble, which has the simple ability to capture infrared radiation, James Webb focuses on light waves, which help detect objects at greater distances.

To date, only groups of stars are found at these distances, especially without the possibility of detecting a star.

But the new star benefited from a cosmic aid represented by an event called gravitational lensing, a group of galaxies located between us and the star that acts as a magnifying glass to amplify the light of the body.

The European Space Agency compared this effect to ripples on the surface of the water, which in good weather emit extended beams of light to the floor of the swimming pool.

Astronomers say this rare alignment will continue in the coming years.

Science Planet Magazine – Mars: The Shy Red Neighbor

Science Planet Magazine – Mars: The Shy Red Neighbor

As the closest planet to Earth; At eighty million kilometers away, Mars is considered a ripe red apple in the field of space exploration. However, the tiny planet presents a major challenge due to its harsh terrain, toxic atmosphere and extreme climate. Mars, named after the ancient Roman god of war, is the fourth planet from the Sun, half the size of Earth, and has two moons: Phobos and Deimos.


The Soviet Union made the first attempt to send a probe to the surface of Mars in the 1960s; However, the probe, nicknamed Marsnik 1, failed to reach Earth orbit, and the mission ended in failure. In 1993, NASA launched the Mars Exploration Program with four ambitious goals: to determine whether the Red Planet was once inhabited, to study and describe the planet’s geography and climate, and finally to prepare for human exploration of the planet’s surface.


Over the years, the project has faced major challenges; From entering the planet’s orbit to landing on its surface. One of the most difficult challenges is developing technologies that can function properly in the hostile environment on Mars; Countless engineering maneuvers had to be performed to ensure that the lander, balloons, and sampling systems functioned properly under the harsh environmental conditions of the Martian desert..


The basic strategy of the project is to look for signs of life to prove whether Mars once existed or in the future could be a habitable environment for biological life forms. Since water is the secret to life, the first missions to Mars – Mars Odyssey 2001, Mars Exploration Rovers, Mars Reconnaissance Orbiter and Mars Phoenix Lander – focused on finding signs of water in the past or present. Images from exploratory missions indicate water was present on the Martian surface in the past, and the sizes, shapes and distribution of geological samples—such as sand, pebbles, and small rocks—strongly indicate that they were formed by and from water. Movement in ancient times..

To date, the Curiosity rover has completed all of its missions. The 899 kg, car-sized rover was launched from Cape Canaveral Air Force Station on November 26, 2011, and landed on the Martian surface on August 6, 2012. Palos Aeolian Plain.*. The probe’s first goal was to spend 687 days in Gale Crater on the surface of Mars. However, continuous combing of the Martian soil took about 1,532 days, or almost four years. Work continued day and night in all seasons of the year, using a special set of radioisotope heat generators; At normal operating temperatures, excess heat is diverted through an indoor greenhouse system to keep the probe’s sensitive electronics that handle sampling and analysis protected from the cold Martian atmosphere..


As Earth’s first rover to Mars, Curiosity has done an excellent job of studying the Martian geography and climate, and investigating whether its chosen research area, Gale Crater, ever hosted microbial life. This study now provides information that will become the foundation for future human exploration on Mars.


However, sending humans to the surface of Mars, which has an atmosphere a hundred times thinner than Earth’s and an average temperature of -63 degrees Celsius, will present an entirely different challenge. Landing a human-carrying spacecraft safely on Mars is extremely difficult due to the planet’s uneven terrain, which consists mainly of mountainous terrain filled with rugged rocky features such as mountains, craters, and trenches. Landing platforms should be carefully selected and landing thrusts should be designed to ensure a smooth and stable landing to avoid overturning of the vehicle.

The future of the Mars exploration program remains uncertain; Due to the enormous cost and exceptionally high failure rates of earlier missions, it became very difficult to mobilize enough public support to fund any other mission. However, scientists still hope that at some point in the future there will be enough will and means to continue the marathon of Martian exploration, and eventually the human race will gather enough knowledge to meet their shy, red neighbor.

Microsoft is adding Copilot, an artificial intelligence chatbot, to all its products and technology

Microsoft announced that it plans to add artificial intelligence chatbot “Copilot” to all its products and services.

CoPilot is available in Windows 11, and the company has now added it to Windows 10, though the company wants every Windows user to try it out.

Windows 10 Home or Pro users in Microsoft’s Release Preview channel can test Copilot now, and Windows 10 users in the company’s supported markets will be able to get this new feature in just a few days or weeks.

Microsoft explained last week that it is “rethinking” its approach to the Windows 10 operating system, and says that it is making “additional investments” in the Windows 10 operating system and that more artificial intelligence features may be in the future. But it said it won’t make any major updates to Windows 10.

Windows marketing vice president Aaron Woodman confirmed in a press conference with The Verge last week that Microsoft will no longer support Windows 10: “We will not make any changes to the company’s end of support date for Windows 10. operating system. It ends on October 14, 2025.

With the Windows 10 operating system still popular, it’s no surprise that CoPilot is coming.

A recent report based on internal Microsoft data revealed that the Windows 11 operating system reached 400 million devices two years after its launch. Windows 10 reached this milestone a year after its release and reached 600 million devices a few months after the second anniversary of its release.

CoPilot in Windows 11 has some integration at the operating system level, as it is included in most applications, while the Windows 10 version is basically the Bing Chat platform available through the Edge browser and cannot open applications, change settings, or interact with it. … anything from Windows 10 native app tasks.

According to Microsoft, the artificial intelligence chatbot Copilot relies on large language modeling technology, and the company hopes that users will enjoy Copilot on Windows via the taskbar or Edge browser, whether they are casual users or employees working in the IT department.

“With CoPilot, you can use the AI ​​experiences you create without sacrificing privacy, and you can stay at the forefront of AI technology while protecting sensitive company data,” the company said.

He added: “Everyday information people are using implicitly generating AI capabilities to help them discover new content, and they’re also directly using CoPilot or ChatGPT in the browser.”

As Microsoft offers a version of CoPilot to enterprise customers, the company confirms that CoPilot on Windows is designed to meet both needs.

Microsoft points to the possibility of using artificial intelligence to create creative content, which could open up new sources of revenue, while the company hopes that Copilot will become an important tool in the Windows ecosystem.
