A star explosion that occurs every 80 years will be visible to the eye!
A rare once-in-80-years cosmic explosion is expected to occur in the Milky Way in the coming months; This explosion is so bright that it will cause a “new” star to briefly appear in the night sky. Here are all the details.
A rare once in 80 years cosmic explosion is expected to occur in the Milky Way in the coming months; This explosion is so bright that it will cause a “new” star to briefly appear in the night sky. Here are all the details.
The event, which occurs every 80 years and is known as Nova, will be a once-in-a-lifetime sky-watching opportunity for those living in the Northern Hemisphere, according to NASA, because the types of star systems where such explosions occur are not common in our galaxy. The starburst will occur in a system called T Coronae Borealis, located 3,000 light-years from Earth. It will contain two stars: a dead star, also known as a “white dwarf,” and stars called red giants. Red giants are dying stars that have run out of hydrogen fuel in their cores.
Like T Coronae Borealis in systems The two stars are so close to each other that matter from the red giant is constantly spilling onto the white dwarf’s surface. Over time, this increases pressure and heat, eventually triggering an explosion. “As matter accumulates on the surface of the white dwarf, it heats up and increasingly higher pressure is achieved until it explodes, creating a reaction that gets out of control,” said Bradley Schaefer, retired professor of physics and astronomy at Louisiana State University.
He compared the nova explosion to a hydrogen bomb exploding in space, adding that the resulting fireball is actually something people can see from Earth. A nova is different from a supernova explosion, which occurs when a massive star collapses and dies. At its peak, the eruption should be visible to the naked eye, Schaefer said: “The sky will be bright for this one-in-80-year event, so it will be easy to see from your backyard.”

NASA’s James Webb telescope pointed to alien life
NASA’s latest observations of James Webb Space Telesobu made the K2‑18b planet, 120 light years, a new focus of review.
NASA’s latest observations of James Webb Space Telesobu made the K2‑18b planet, 120 light years, a new focus of review.
Discovered during NASA’s K2 mission in 2015, this world is located in the “Goldilocks” area of a cold red dwarf star in the lion constellation. The fact that the world mass has approximately 8.6 times makes this planet remarkable in terms of liquid water hosting potential.
The infrared spectrometer of WebB pointed out the presence of methane (CH₄), carbon dioxide (CO₂) and dimethyl sulfide (DMS) in addition to Hubble data. DMS produced by microorganisms in the world oceans is considered a strong sign of biological activity.
Hydrogen -rich thick atmosphere under a large liquid water ocean to be found Possible K2‑18B can contain high -pressure ice layers or hot ocean surfaces with its size reaching 2.6 world radius. The complex carbon compounds detected in the atmosphere provide a potential livability sign.
The team, led by Nikku Madhususudhan of Cambridge University, positioned K2‑18B among the oloan Hycean ”class among the outer planets. Thick atmospheres of Hycean worlds provide advantage for the discovery of biosinians.
The research team is cautious about the temporality of dimethyl sulfide detection and plans to perform additional observations with NASA James Webb Space Telescope’s Middle Infrared Instrument (MIRI) to finalize the finding. These examinations will confirm the DMS signal, elaborate the distribution of water vapor and investigate the presence of other carbon -based molecules. Thus, more comprehensive data on the physical and chemical properties of K2‑18B is to obtain more comprehensive data and to create a new milestone in extraterrestrial life research.

Crisis Grows at Boeing; 17 Thousand People Will Be Dismissed
The crisis is growing in Boeing, which has recently come to the fore with successive failure news; The company announced that it would lay off 17 thousand people.
The crisis is growing in Boeing, which has recently come to the fore with successive failure news; The company announced that it would lay off 17 thousand people.
Boeing, which was once one of America’s most successful and prestigious companies, has now turned into one of the most controversial and unreliable companies in the aviation industry. On the one hand, security risks and unreliable inspection practices in the aircraft produced by the company were brought to the agenda, and on the other hand, the company’s space tourism dreams were dashed. Starliner, the spacecraft developed by Boeing with great hopes, failed in its first manned mission to the International Space Station.
Starliner, which had problems returning after carrying the astronauts to the International Space Station, finally returned alone without taking the astronauts after being stranded there for months. SpaceX brought back the astronauts who were stranded on the ISS. This entire fiasco caused not only the Starliner project, but also Boeing a great loss of prestige. These consecutive fiascos have put the company in a major crisis today. So much so that the company had to make one of the biggest layoff decisions in its history.
Boeing announced this week that it would lay off 17 thousand people. announced. This equates to 10 percent of the company’s total workforce, which is something we rarely see such a significant downsizing for a company of this size. Therefore, it also reveals the extent of the crisis in the company.
These layoffs are said to be linked not only to the Starliner debacle and the decline in confidence in the company’s aircraft, but also to discord within the company. Thousands of people from the engineers union, which Boeing management cannot agree with, are currently on strike. This put the company, which was already going through a difficult period, into an even bigger crisis. There is a possibility that the current layoff decision will deepen this crisis even further. Because this decision will further anger the union members who are on strike.

Boeing May Scrap the Starliner Project
Boeing may give up hope on the Starliner spacecraft, which is halfway through its first real mission, and completely scrap the project on which it spent billions of dollars.
Boeing may give up hope on the Starliner spacecraft, which is halfway through its first real mission, and completely scrap the project on which it spent billions of dollars.
Boeing, the aviation company that aims to compete with companies such as SpaceX and Blue Origin with the space shuttles it has developed, came very close to making this dream a reality in June. The space shuttle Starliner, which Boeing has been working on for a long time, successfully completed its journey to the International Space Station on June 6 and delivered the two astronauts it carried to their places of duty in low Earth orbit. Boeing would finally receive the reward of its years of efforts and billions of dollars of investment…
Until preparations began for the return of the Starliner. When NASA began conducting tests for the return, it realized that its Starliner was not fit for return. Having done its best to make Starliner suitable for return in the past three months, NASA finally threw in the towel last week and admitted that it was unable to bring back the astronauts Starliner had taken. Moreover, SpaceX’s space shuttle would “rescue” the astronauts who were stranded on the ISS for months because of Boeing’s space shuttle.
This adventure, in which Boeing set out with the dream of participating in the space race, turned into one of the biggest fiascos of recent years. This crisis, which caused Boeing to seriously lose its prestige, also shook the confidence in the company’s space vehicles. So much so that this project may go to waste altogether.
This week, Boeing executives were asked whether the Starliner project would continue despite this setback. The Boeing executive’s illegal answer to this question did not go unnoticed. If there was no truth behind the rumors, the Boeing executive would definitely say that such a situation is out of the question and emphasize their determination on this project. But it didn’t happen that way. Boeing executive refuses to make a statement in this direction avoided. This showed that the company may have to completely abandon this project, for which it actually spent 1.6 billion dollars.
As if this were not enough, Boeing’s other projects at NASA are now also being reviewed. Certain parts of the SLS, which will be used in NASA’s flight to the Moon, were also produced by Boeing. New reports that have emerged now show that Boeing is both far behind the schedule and already over its budget in these projects.
