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.

WASHINGTON — Facing rising costs, the European Space Agency is looking at ways to revise the design of a large X-ray space telescope, an effort that could have implications for NASA’s own astrophysics program. ESA selected the Athena mission in 2014 as one of the two flagship astrophysical missions, along with the Laser Interferometer Space Antenna (LISA). Athena — the name comes from the Advanced Telescope for High-Energy Astrophysics — will launch in the mid-2030s to study supermassive black holes, supernova explosions, and other X-ray sources using large X-ray mirrors. At the time of the election, each mission had an estimated cost to ESA of 1.05 billion euros ($1.07 billion), or about 1.17 billion euros today, said Paul McNamara, ESA’s astronomy and astrophysics coordinator, during a July 21 presentation to NASA astronomers and astrophysicists. committee. However, in 2019, the combined price of Athens and LISA has grown to 2.5 billion euros. As of May 2022, LISA had an estimated

The Southern Hemisphere’s first deep-sky telescope is poised to shed new light in some of the darkest parts of the universe, as it begins its survey of western New South Wales. Developed by Macquarie University, the Hunter Telescope has been unveiled at the Siding Spring Observatory, nestled among the mountains of the Warrumbungle Range near Coonabarabran. Project team member Sarah Caddy says the Huntsman design allows for highly specialized research into the formation and evolution of galaxies. “When we look for very dim objects, objects with low surface brightness, we want to collect as much light as possible,” he said. Built almost entirely from ready-to-use technology, the Hunter’s “eyes” are Canon’s 10 telephoto lenses. ( ABC Western Plains: Nic Healey ) “With traditional mirror-based telescopes, they can scatter light into parts of the field of view that we don’t want … that makes it very difficult to find very dim things around galaxies. “What we do is we have 10 lenses, all l

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.

The July supermoon, the month of Buck, hangs in the sky for four days this week, providing the perfect opportunity for photographers to showcase their lunar lens work. From Sydney to Seattle, Tehran and Istanbul – here are some of the best shots taken from around the world. Watch the video above to hear NASA’s warning that China could try to take over the moon Watch the latest News on Channel 7 or stream for free on 7plus >> The supermoon is visible from Tuesday to Friday according to NASA, and reaches its peak Thursday at 4:48 a.m. AEST. Clouds and overcast weather made the moon a little more elusive in Australia this week, but that didn’t stop avid photographers getting their cameras out. While there is no single definition of “supermoon,” the term usually refers to a full moon that can stand out more than the others because it is within 90 percent of its closest orbit to Earth. Of all the supermoons this year, the Buck Moon will come closest to Earth, according to Old Farmer’

A mysterious radio explosion with a pattern similar to a heartbeat has been detected in space. Astronomers estimate that the signal came from a galaxy about a billion light years away, but the exact location and cause of the explosion is unknown. A study detailing the findings published Wednesday in the journal Natural . Rapid radio bursts, or FRBs, are intense, millisecond-long bursts of radio waves of unknown origin. The first FRBs were discovered in 2007, and since then, hundreds of these rapid cosmic flashes have been detected coming from various distant points throughout the universe. Watch the latest News on Channel 7 or stream for free on 7plus >> Many FRBs release super-bright radio waves that last only a few milliseconds before disappearing completely, and about 10 percent of them are known to repeat and have patterns. Fast radio bursts are so fast and unpredictable that they are difficult to observe. One of the sources used to find them is a radio telescope called th

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
