The new system also means that media shared by accounts with a blue tick is ranked higher in Twitter’s algorithms, meaning that entire networks of misinformation spreaders can get synthetic media like this into more people’s feeds by virtue of their paying $13 a month for Twitter Blue.Loading“I think that this particular image was algorithmically boosted by accounts that had bought verification. In essence it’s easier now, much easier, to have misinformation go viral on Twitter,” Barnet said.“It’s somewhat ironic that is…

Breaking news: The U.S. Pentagon is NOT under attack. But that didn’t stop false reports of an explosion from circulating widely online along with a seemingly AI-generated image of billowing black smoke near the Department of Defense headquarters on Monday.How To Remove Followers From TwitterMultiple blue-check “verified” Twitter users re-posted the fake photo along with text insinuating an active emergency situation was ongoing at the Pentagon, and later the White House. Accounts amplifying the false narratives included…

The research team hopes to clarify the relationship between the emitted strong radio waves and this stripped material. Credit: Adam Makarenko/W. M. Keck ObservatoryIn the latest issue of the journal Nature, astronomers from Stockholm University reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first…

Astronomers have observed the biggest cosmic explosion ever detected, and it is estimated to be 100 times the size of our solar system. Further, the explosion is estimated to be two trillion times brighter than our Sun at its solar peak, and it has remained visible for three years after the explosion. Our universe is full of intriguing and awe-inspiring events, like rogue black holes romping through space, or galaxies colliding with each other to create even bigger, more massive galaxies. So, when astronomers…

Astronomers have witnessed the largest explosion in space.  The explosive event labeled AT2021lwx was observed to be ten times brighter than any known supernova, the explosions that occur as massive stars die. And whereas supernova explosions only last a few months, this explosive event has been raging for at least three years.  AT2021lwx is also three times brighter than the light that is emitted as stars are ripped apart and devoured by supermassive black holes, occurrences called "tidal disruption events" or "TDEs."…

Astronomers said on Friday they have identified the "largest" cosmic explosion ever observed, a fireball 100 times the size of our Solar System that suddenly began blazing in the distant universe more than three years ago.While the astronomers offered what they think is the most likely explanation for the explosion, they emphasized that more research was needed to understand the puzzling phenomenon.The explosion, called AT2021lwx, is not the brightest flash ever observed in the universe. That record is still held by a…

Astronomers have seen the most energetic cosmic explosion yet, which they believe resulted from a gas cloud being disrupted by a supermassive black hole.First Full-Color Images From Webb Space TelescopeThe explosion (dubbed AT2021lwx) happened billions of light-years away and was first spotted in 2020. But now it’s lasted over three years, indicating the sheer amount of material involved in the event. The team’s research describing the explosion was published today in Monthly Notices of the Royal Astronomical…

Scientists have detected the ripple effects of small ground-level explosions 100 kilometers up in ionized layers of the upper atmosphere. The result suggests the remote sensing technique could be used to monitor explosive events—natural or human—hundreds of times smaller than before. “It was a big surprise to me,” says Jihye Park, a geodetic scientist at Oregon State University who was not involved in the research. “It’s really smart.” The ionized region of the…

Artist impression of a black hole accretion. Astronomers led by the University of Southampton have discovered the largest cosmic explosion ever observed, known as AT2021lwx. Over ten times brighter than any known supernova and three times brighter than the brightest tidal disruption event, the explosion has been ongoing for more than three years. Researchers believe the explosion is due to a massive gas cloud, possibly thousands of times larger than the sun, being violently disrupted by a supermassive black hole. Credit…

The possibility of the Sun causing catastrophic damage on Earth might seem something out of a science-fiction film, but this threat is very true. One of the best examples of Solar activity harming Earth was provided by the Roland Emmerich film 2012. It depicted the apocalypse prophesied by the Mayans many centuries ago. The storyline of the movie revolved around the Sun emitting unstable neutrinos because of anomalous energy processes, which were causing the Earth's core to heat up and eventually lead to its destruction.…
