A Forgotten Cosmic Impact Was Hidden in a Museum’s Glass Shards  The New York Times Source link

Sign up for the Starts With a Bang newsletter Travel the universe with Dr. Ethan Siegel as he answers the biggest questions of all. If you want to see the Universe, you have to do more than merely open your eyes. Even with the advantage of large, powerful telescopes, even from far above the limitations of Earth’s atmosphere in space, …

IN A NUTSHELL 🔭 Researchers using the James Webb Space Telescope found a pattern in the rotational direction of ancient galaxies. 🌀 Approximately 60% of these galaxies rotate clockwise, challenging previous beliefs about galactic rotations. 🌌 A hypothesis suggests our universe might be trapped within a massive black hole, reshaping cosmic understanding. 🔍 Alternative explanations consider observational bias, such as …

Using a powerful combination of the Subaru Telescope and the James Webb Space Telescope (JWST), astronomers have discovered seven supermassive black hole-powered quasars surrounded by veils of dust that existed when the universe was less than a billion years old. Supermassive black holes consuming vast amounts of matter and shining as bright quasars while being hidden in thick clouds of …

A cosmic shark hunts through deep space. (Image credit: Ronald Brecher) Astrophotographer Ronald Brecher captured a haunting vista in July earlier this year, in which several deep-sky objects take on the collective appearance of a colossal cosmic shark hunting in the depths of space. The body of Brecher‘s shark is comprised of a vast interstellar cloud of dust and gas …

The universe’s first magnetic fields may have been much weaker than we first imagined — and were roughly equivalent to the strength of the magnetic activity within the human brain, according to a new study. Researchers used hundreds of thousands of computer simulations to examine the remnants of these ancient magnetic fields, which still reside within the “cosmic web” billions …

It’s human to feel alarmed by the sheer emptiness of space. Now, astronomers from the University of Portsmouth in the UK suggest this unsettling vastness may be worse than we thought. More mind-blowing space science Credit: solarseven / Getty Images They reckon Earth, our entire Solar System and even our entire Milky Way sits inside a mysterious giant hole. This …

NEW YORK — Astronomers have spotted the brightest fast radio burst yet coming from a nearby galaxy. Observations of this phenomenon, a powerful flash of radio waves that lasts only about one millisecond, could shed light on one of the most mysterious cosmic phenomena ever studied. Fast radio bursts, or FRBs, were first discovered in 2007, but their exact sources …

New research suggests we may live in a vast cosmic void, a region with far fewer galaxies and matter than expected. This finding could explain why the universe around us seems to be expanding faster than models predict, a puzzle known as the Hubble tension.
