Astronomers See Black Hole Swallow Neutron Star For First Time Ever.

Black Hole Swallows Neutron Star For The First Time.“It was just a big quick (gulp), gone,” said Patrick Brady, an astrophysicist at the University of Wisconsin Milwaukee.

Talk about a heavy snack. For the first time, astronomers have witnessed a black hole swallowing a neutron star, the most dense object in the universe — all in a split-second gulp.

Ten days later they saw the same thing, on the other side of the universe. In both cases, a neutron star — a teaspoon of which would weigh a billion tons — orbits ever closer to that ultimate point of no return, a black hole, until they finally crash together and the neutron star is gone in a gobble.

Astronomers witnessed the last 500 orbits before the neutron stars were swallowed, a process that took far less than a minute and briefly generated as much energy as all the visible light in the observable universe.

“It was just a big quick (gulp), gone,” said study co-author Patrick Brady, an astrophysicist at the University of Wisconsin Milwaukee. The black hole “gets a nice dinner of a neutron star and makes itself just a little bit more massive.”

The bursts of energy from the collisions were discovered when detectors on Earth spotted the mergers’ gravitational waves, cosmic energetic ripples soaring through space and time as first theorized by Albert Einstein. They each came from more than one billion light-years away. The waves were detected in January of 2020, but the study analyzing and interpreting the data by more than 100 scientists was published Tuesday in Astrophysical Journal Letters.

Black Hole Swallows Neutron Star For The First Time

While astronomers had seen gravitational waves from two black holes colliding with each other and two neutron stars colliding with each other, this is the first time they saw one of each crashing together.

Neutron stars are corpses of massive stars, what’s leftover after a big star dies in a supernova explosion. They are so dense that they have about 1.5 to two times the mass of our sun, but condensed to about 6 miles (10 kilometers) wide, Brady said. Some black holes, known as stellar black holes, are created when an even bigger star collapses into itself creating something with such powerful gravity that not even light can escape.

Scientists think there should be many of these neutron star and black hole pairings, but they’ve yet to find one in our own galaxy.

“This is very cool,” said Johns Hopkins University astrophysicist Marc Kamionkowski, who wasn’t part of the research. He said this will help astronomers predict how abundant these pairings are.

She finds that humans will be quite “optimistic” about the discovery of extraterrestrial life.

How Does the Discovery of Extraterrestrial Life Happen? As the possibilities for a non-human intelligence to exist on Earth increase with each passing day, a critical question must be asked:

How do we deal with it if we make contact?

Are we afraid if we feel threatened?

Will we accept? can we realize Or will we ignore it as another element that we have to deal with in our increasingly accelerating world?

Researchers from Arizona State University did a research to find the answer to the question and what was the title of the article.

“How Do We Respond to the Discovery of Extraterrestrial Life?” it happened.

Researchers l oked how such previous announcements have been used in the media, with an emphasis on foreign microbial life in that language (Pilot Study). A large online sample was asked to write about themselves and humanity’s response to a hypothetical announcement of such a discovery, and another large online sample was asked to read and respond to a news article about the discovery of fossilized extraterrestrial microbial life in a Martian meteorite. .

Varnum presented the study’s findings February 16 at the American Association for the Advancement of Science annual meeting in Austin, Texas.

Articles from the pilot study focused on the discovery of possibly fossilized extraterrestrial Martian microbes in 1996, the 2015 discovery of periodic dimming around Tabby’s Star thought to indicate the existence of an artificially constructed “Dyson sphere”, and the discovery of Earth-like exoplanets in 2017. habitable zone of a star.

The pilot study discovered that the language used to describe these events was much more positive than negative emotions.

In a second study, researchers invited more than 500 people to write about their possible response to the discovery of alien microbial life, and humanity’s possible response. When considering individual emotions as well as humanity as a whole, participants’ responses revealed that they were much more positive than negative emotions.

Varnum’s group then provided an additional sample of more than 500 people with historical reports of scientific breakthroughs and asked them to write about their feelings in another study. Participants were divided into two groups. Participants in one group read an earlier article from The New York Times about possible evidence of ancient microbial life on a Martian meteorite. The second group of contributors wrote a report from the New York Times on the supposed development of synthetic man-made life in a lab.

Scientists discovered evidence of being much happier with negative emotions in responses to the alleged finding of alien life, and the effect was greater in response to reading about extraterrestrial life than in response to man-made synthetic life.

Varnum reviewed recent media coverage of the potential of the interstellar asteroid Oumuamua to actually be a spacecraft in unpublished data provided at the conference. Here, too, he discovered more positive evidence than negative emotions, implying that people might respond positively to news of finding life elsewhere in the cosmos.

According to Varnum, “taken together, this means we’ll get the news pretty well if we learn we’re not alone.”

Jeff Bezos Announces She’s Going To Space. The Amazon CEO said he’ll be ready the primary maintained trip of the New Shepard, a rocket made by his organization Blue Origin.

Amazon author and CEO Jeff Bezos reported Monday that he will space on the primary maintained trip of the New Shepard, a rocket made by his organization Blue Origin.

Bezos ― the most extravagant individual on the planet with a total assets more than $200 billion ― will be joined on the trip by his more youthful sibling, Mark Bezos.

“Since the time I was five years of age, I’ve longed for going to space,” Bezos wrote in a post on Instagram. “On July twentieth, I will take that venture with my sibling. The best experience, with my dearest companion.”

The flight is booked for July 20, around fourteen days after Bezos is set to leave as Amazon CEO.

The New Shepard ― named for Alan Shepard, the main American in space ― highlights a six-seat case and 59-foot rocket. It has flown 15 fruitful successive missions to space and back, as indicated by Blue Origin.

The previously run flight will traverse 11 minutes and arrive at in excess of 60 miles above Earth, announced CNN.

“I need to go on this flight since it’s a thing I’ve needed to do for my entire life,” Bezos said in a video presented on Instagram. “It’s an experience. It’s nothing to joke about for me.”

Offering for another seat on the flight is open until June 12, Blue Origin tweeted. As of Monday, in excess of 6,000 bidders from 143 nations had taken an interest in the closeout, with the most elevated bid at $2.8 million, as indicated by Blue Origin.

The triumphant bid will sum will be given to Blue Origin’s STEM-centered establishment, Club for the Future, the organization said in an official statement.
