Researchers have just studied the oldest lensing of light we can see and found the oldest dark matter ever observed, around a galaxy 12 billion years old. They spotted this dark matter by looking at how some galaxies bend the cosmic microwave background light, the earliest detectable radiation after the Big Bang, that rocked the universe as we know it. The team’s research is published in Physical Review Letters. “Most researchers use source galaxies to measure the distribution of dark matter from now to eight billion years ago,” said Yuichi Harikane, astronomer at the Institute for Cosmic Ray Research at the University of Tokyo and co-author of a recent paper, in a Nagoya University release. . “However, we were able to look further into the past because we used the CMB further afield to measure dark matter. For the first time, we’re measuring dark matter almost from the early days of the universe.” Dark matter makes up about 27% of the universe, al...

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 reco...

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/5AcOBwHuO...

Researchers have tracked the oldest known Martian meteorite to its precise point of origin using artificial intelligence (AI), and the findings could help reveal what conditions were on our planet. solar system the planets were like during their first days. The 11 ounce (320 gram) meteorite, officially nicknamed Northwest Africa 7034 but commonly known as “Black Beauty,” is believed to have hit Earth about 5 million years ago. After being discovered in the Sahara Desert in 2011, its age was estimated to be just under 4.5 billion years – making it the oldest Martian meteorite ever found on Earth. Scientists believe the meteorite was launched to Earth after a powerful asteroid impact hit Mars, tearing apart parts of the planet’s crust and spraying it into space. Now, using machine learning algorithms to identify and catalog the 94 million craters on Mars, researchers have traced the origins of Black Beauty to small craters within craters in Mars’ southern ...

Meteorite NWA 7034, nicknamed Black Beauty, has fascinated geologists since it was discovered in the Sahara Desert in 2011. Scientists announced Tuesday that they have discovered the crater where the oldest known Martian meteorite was originally blasted toward Earth, a discovery that could provide clues as to how our own planet formed. Meteorite NWA 7034, nicknamed Black Beauty, has fascinated geologists since it was discovered in the Sahara Desert in 2011. It fits in the hand, weighs over 300 grams (10.6 ounces), and contains a mix of materials including zircon, which is nearly 4.5 billion years old. “That makes it one of the oldest rocks studied in geological history,” Sylvain Bouley, a planetary scientist at France’s University of Paris-Saclay, told AFP. Its journey dates back to the early days of the solar system, “about 80 million years after the planets began to form”, said Bouley, who co-authored the new study ...

ANI | Updated: 09 July 2022 20:19 IST Toronto [Canada]July 9 (ANI): As per new research, scientists have now discovered 1.2 billion year old deep groundwater in gold and uranium mines in South Africa, shedding more light on how life is sustained beneath the earth’s surface and how it may have come about . survive in another world. The findings of this study were published in the journal ‘Nature Communications’. “For the first time, we have insight into how energy stored deep beneath the Earth’s surface may be released and distributed more widely through its crust over time,” said Oliver Warr, research associate in the Department of Earth Sciences at the University of Toronto and lead author of the study. . “Think of it as Pandora’s Box of helium and hydrogen-producing forces, which we can learn how to harness to the benefit of the biosphere on a global scale.” ...

The strange creatures that raged in Earth’s oceans more than half a billion years ago appear to be the earliest vertebrate relatives we’ve found to date. They are called yunnanozoans, dating from the Early Cambrian about 518 million years ago. The cartilaginous features found in their fossil remains are comparable to those of modern vertebrates, paleontologists have found. This suggests that these animals were stem vertebrates, an extinct sister group to the original group of modern vertebrates. “The pharyngeal curvature is a key innovation that likely contributed to the evolution of the vertebrate jaw and braincase,” wrote the team led by Qingyi Tian of Nanjing University and the Chinese Academy of Sciences in China. “The pharyngeal skeletons of controversial Cambrian animals called yunnanozoans may contain the oldest fossil evidence limiting the early evolution of arches, but their correlation to vertebrates is debated. “By examining additional spe...
