Mysterious fire ring discovered outside our galaxy ... Scientists reveal the secret of its existence |  Science

Researchers hope to pursue more in-depth and comprehensive research to confirm the nature of the rogue supernova, which could be useful in improving scientists’ understanding of this type of substance.

An international team of scientists led by researchers at the University of Western Sydney in Australia has discovered a mysterious ring-like object near our Milky Way galaxy, which may be the first in astronomical history.

Mysterious circles

Just StudyPublished in monthly announcements, the researchers used the ASKAP or Australia’s Pathfinder Square kilometer line to achieve their findings.

ESCAP is a radio telescope located in the western part of Australia and consists of 36 antennas, each 12 meters in diameter, representing a large antenna covering an area of ​​4,000 square meters. Construction began in late 2009. And came into operation in 2012.

ESCAP was able to observe this mysterious ring outside the Milky Way galaxy known as the Great Magellanic Cloud (LMC), a galaxy 160,000 light years away from us.

The Ring of Fire is located next to the Great Magellanic Cloud, the satellite galaxy of the Milky Way (University of Western Sydney).

Just Official report Published by the University of Western Sydney, the research team was surprised to find a celestial body of this shape outside the galaxy, at first they thought it was a “strange radio circuit” and spherical radio objects incomprehensible to radio circles. Discovered in 2019 and are believed to have originated from galaxies.

But after further study, scientists discovered that this mysterious ring may be the remnant of a star that erupted about 2200-7100 years ago, forming a giant supernova, the remnants of which erupted are still expanding, in light of the study’s estimate.

Rogue Supernova!

This means that, according to the research team, this is the first time a supernova has been detected outside the Milky Way, which is why they called this ring of fire “rogue”. It was as if the star had left the star galaxy in obedience.

According to a new study, the “Rogue” star appeared from the Great Magellanic Cloud millions of years ago, surrounded by a sub-star, one of which was in the red giant phase and the second in the white dwarf phase. . The second one had a strong gravitational pull so it pulled the red giant object very quickly.

The Ascap Observatory in Western Australia has 36 plates (Wikipedia)

As the material of the red giant accumulates rapidly and strongly on its dwarf companion, rapid and abrupt nuclear reactions occur on the surface of the white dwarf, and at one point it explodes, forming what is known as a “supernova Ia”.

Because of this strange situation, researchers in this group hope to carry out more in-depth and comprehensive research to confirm the nature of the rogue supernova, which will be useful in developing scientists’ understanding of this type of material.

Scientists are tracking a tree in Brazil that was thought to have died out 185 years ago



Scientists are tracking a tree in Brazil that was thought to have died out 185 years ago

I retired at 100… A centenarian talks about the importance of “being busy at work” to live a long life.

Madeleine Balto recently retired at the age of 100, having worked for more than 80 years – from the age of 18 to 99. According to a CNBC report, Balto believes work has contributed to his longevity.

Balto says of his previous job: “It kept me busy, and I enjoyed the work… As for retirement, I don’t really like it.”

The Balto family started an electric sign manufacturing business in Chicago, with Madeline responsible for office work. She often interacted with customers and it was her favorite job.

She said: “I loved interacting with people… and I was the only one in the office doing all the office work, so it was fun.” “I loved going to work.”

An 85-year-old Harvard University study found that positive relationships make people happier and help them live longer. For this reason, it is not surprising that Balto places a strong emphasis on the importance of family and friends.

Assistant Professor of Medicine and Genetics and Director of Human Lifespan Studies at the Albert Einstein Institute for Aging Research, Dr. Sophia Melman says. College of Medicine.

At 100, Balto maintains his sense of community by going out to dinner with his sons and attending family events. Finally attended a wedding earlier this month.

She also likes going to the Dunkin’ Donuts branch every Sunday with her son to meet friends. “I look forward to it every week,” he says.

Balto affirms that she is lucky; Because she has some friends of the same age who often come to her house for lunch.

She added: “They always invite me over and come over for lunch on Wednesdays at 12pm… we have fun together… without your friends, where are you, right?”

While maintaining healthy relationships is an important factor in living longer, there are other factors that contributed to Balto’s longevity.

First, Mellman says, “In general, women’s life expectancy is longer than men’s…and we believe that genetics also has a significant relationship with longevity.”

In fact, Balto’s older sister lived to be 103 years old. “But she and I are the only ones who lived over 100 years,” she says, referring to her parents, who died at 84, and her sisters, who didn’t live very long.

I grew up on a vegetarian diet

Aiming to stay active, Balto says, “I’m still getting around better. I can walk up the stairs. I have energy; “so I’m in pretty good shape.”

She also tries to eat as healthy as possible, something that started in her childhood, she explains: “When I was a child, there were seven children in the family, and my father was building a big garden, so we lived mostly. On vegetables. “There wasn’t a lot of meat, we couldn’t afford meat.”

“I think that’s probably why I eat healthier,” she adds. Don’t eat fast food now.

Millman says centenarians are generally more confident, and Balto fits that description. He says it’s unclear whether centenarians are always positive, or whether they develop their positive outlook as they age.

Balto says she doesn’t feel too nervous; Because “everything can be solved.” She continues: “I’m very lucky; As I am 100 years old, I am in good health… I cannot complain about my health. “I’m walking, talking, no pain.”
