Fossil remains of the black hole-eating frenzy of the past have been found deep within one of the largest galaxy clusters in our sky. Astronomers also saw physics-defying plasma shockwaves, and loops of radio energy within the same galaxy cluster. Key points: Astronomers have discovered a trio of rare objects in a distant galaxy cluster known as Abell 3266 One of the mysterious objects is a shockwave relic dubbed the “wrong way”. The objects were discovered using radio telescopes in Western Australia and New South Wales The cluster – Abell 3266 – is located 800 million light-years away and spans the sky 300 million light-years in the southern constellation Reticulum. An international team of astronomers, led by Christopher Riseley of the University of Bologna in Italy, studied the cluster in detail using the powerful Australian Square Kilometer Array Pathfinder radio telescope in outback Western Australia, and the smaller Australia Telescope Compact Array in Narrabri, New South Wales.

The universe is filled with galaxy clusters – massive structures piled up at the intersection of the cosmic web. A single cluster can span millions of light years and consist of hundreds, or even thousands, of galaxies. However, these galaxies represent only a few percent of the total mass of the cluster. About 80% of it is dark matter, and the rest is hot plasma “soup”: gas heated to above 10,000,000℃ and entwined with weak magnetic fields. We and our team of international colleagues have identified a series of rarely observed radio objects – radio remains, radio halos, and radio emission fossils – in a highly dynamic galaxy cluster called Abell 3266. They challenge existing theories about the object’s origin. and their characteristics. Relics, halos and fossils Clusters of galaxies allow us to study a rich variety of processes – including magnetism and plasma physics – in environments that we cannot recreate in our laboratories. When the clusters collide with each other, a large a

the little one The dim, red dot in the center of the newly released image of a distant galaxy indicates the galaxy underwent one of the most powerful explosions since the Big Bang. Astronomer Brendan O’Connor and his colleagues recently discovered this as-yet-unnamed galaxy 9 billion light-years away in data from the Gemini North Telescope in Hawai’i, and they say it is the source of a brilliant, bright beam of gamma radiation. brief dazzling NASA. Swift Observatory in late 2015. Imagine an explosion releasing as much energy as our Sun would in 10 billion years – compressed into an explosion in less than two seconds. Astronomers call this almost unimaginable catastrophe a short gamma-ray burst, and the universe hasn’t seen a brighter or more powerful explosion since the Big Bang. What could cause such an event? The answer appears to involve two colliding neutron stars. Binary star systems are not very rare in the universe; one of our closest neighbors, Alpha Centauri, is actually

Not all stars enjoy just wandering around, orbiting the galactic center with all the other stars. Some stars go rogue, crossing the Milky Way with significant force. It is a runaway star, and we can trace its trajectory to understand the violent events that could occur in the Universe. One such star, and one of the more famous ones, is Zeta Ophiuchi. Located about 440 light-years from Earth in the equatorial constellation Ophiuchus, it is also one of the strangest stars in the sky. Not only is it incredibly fast, at about 30 to 40 kilometers (roughly 20 to 25 miles) per second, but it’s a strange type of star to see roaring in space. Zeta Ophiuchi is the main sequence star; that is, one that still combines hydrogen into helium in its core. And it’s a hot, massive O-type star: about 20 times the mass of the Sun, glowing blue with intense heat. Such stars also have relatively short lives; Zeta Ophiuchi is about half way past the main sequence’s projected age of 8 million years. Tha

Origin of ‘ghost particles’ DISCOVERED: Tiny bodies that pass through our body and planet undetected emitted from galactic cores fed by supermassive black holes in outer space ‘Ghost particles,’ or neutrinos, are particles that originate from outer space These particles have no mass and hardly interact with matter Scientists believe they came from the core of a galaxy that was fed by a supermassive black hole Blazars are known for emitting bright beams of light and wind and are thought to also produce cosmic rays By Stacy Liberatore For Dailymail.com Published: 2:04pm EDT, July 25, 2022 | Updated: 2:18 p.m. EDT, 25 July 2022 Extraterrestrial ‘ghost particles’ likely originate from the cores of galaxies fed by supermassive black holes, according to a new study that could unravel the mystery of subatomic particles that formed before the universe. Ghost particles, or neutrinos, have baffled scientists since they were firs

If you are already following astronomy community on Twitter or maybe, Captain America himself You may have come across the story about the latest discovery of the James Webb Space Telescope: “The oldest galaxy we have ever seen.” This is exactly as promised from the James Webb Space Telescope. Just a week ago, the collective jaws of the world hit the floor when First amazing picture revealed . Now, the telescope started off right myriad science programs but researchers already have access to much of the data collected during the commissioning phase of JWST and released earlier to researchers around the world. That’s how we ended up discovering the “oldest galaxy” so quickly. Scientists examine specific data sets to search for distant galaxies and find a candidate they have dubbed the GL-z13, a callback to the current confirmed record holder, the GNz11. There’s still a lot of work to be done to make sure the GL-z13 is actually the new record holder — some of which will take

Just a week after its first images were shown to the world, the James Webb Space Telescope may have discovered a galaxy that existed 13.5 billion years ago, a scientist analyzing the data said Wednesday. Known as GLASS-z13, this galaxy dates back to 300 million years after the Big Bang, about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for Astrophysics told AFP. “We are potentially seeing the light of the most distant star that anyone has ever seen,” he said. The further away the object is from us, the longer it will take for its light to reach us, and so gazing back into the distant universe is looking into the deep past. JWST has the potential to break records, discovering galaxies that existed when the universe was only 300 million years old! Light from GLASS-z13 took 13.4 billion years to reach us, but the distance between us is now 33 billion light years due to the expansion of the universe! pic.twitter.com/5AcOBwHuO1 — Dr. Ja

From a young age, astrophysicist Robin Cook had a deep desire to understand the world around him. “It’s never nice enough to take things at face value … I’ve always wanted to understand how things work,” he said. It was this natural curiosity that led him to pursue a career researching space and the unknown. “It’s not too surprising that I naturally went into astronomy,” he said. “There are so many unanswered questions in astronomy, we actually have pretty limited knowledge of what’s really out there. “And for me, it’s very interesting.” Seeing the galaxy’s ‘beautiful spiral’ Dr Cook is a research associate at the International Center for Radio Astronomy Research (ICRAR), which is run by Curtin University and the University of Western Australia. Founded in 2009, the research center conducts data-intensive astronomy, engineering and science. Dr Cook studies the structure of galaxies. ( Provided: Robin Cook ) Dr Cook’s area of ​​research at ICRAR is on the evolution of galaxies, more sp

There are hundreds of billions of galaxies in the universe, each containing billions of stars, and they are found in every part of the sky. But in some directions, nearby galaxies block the view of the more distant cosmos. Now a team from Keele University has created the largest map of a previously hidden galaxy. Jessica Craig presented their work this week at the National Astronomy Meeting at the University of Warwick. Astronomers saw the Magellanic Clouds, a pair of galaxies visible from the southern hemisphere that are so close to us that they can be seen with the naked eye. The two galaxies occupy large areas of the sky, blocking the view of more distant galaxies. Because of this, astronomers looking for distant galaxies usually avoid this part of the sky. Using the VISTA Survey Telescope in Chile, the team photographed two nearby galaxies in high enough definition to be able to see through the gaps between the stars in each. That way they can see galaxies that are farther awa

Get ready to travel back into the universe earlier this week as scientists prepare to reveal the most detailed snapshot ever taken of our cosmos. One of the first full-color images released from the new James Webb Space Telescope (JWST) promises to catapult us further into the past than we’ve ever seen before. Load “We will give humanity a new view of the cosmos,” said NASA administrator Bill Nelson. The image, which will reveal some of the earliest galaxies and stars that formed after the Big Bang 13.8 billion years ago, is one of four to be released at 12:30 a.m. (AEST) on Wednesday. “What I’ve seen has moved me as a scientist, as an engineer, as a human being,” said NASA deputy administrator Pam Melroy. Along with the deepest views of the universe, other images the team promised to blow our heads include: The spectacular dust cloud known as the Carina Nebula, the birthplace of stars A group of colliding galaxies called Stephan’s Quintet A large gas bubble known as the Southern Ring
