Scientists using the James Webb Space Telescope spotted a supernova whose light is taking multiple paths through space, with some images arriving now and others delayed by six decades. This cosmic phenomenon could finally help solve one of astronomy's biggest mysteries about how fast the universe is expanding.
Scientists have finally captured definitive gamma-ray evidence of a supercharged supernova, revealing how the most magnetic objects in the universe are born. After nearly 20 years of searching, NASA's Fermi spacecraft witnessed a stellar explosion powered by a newborn magnetar spinning 700 times per second.
Scientists discovered what could be a 1,700-year-old supernova remnant racing through space at two million miles per hour, incredibly close to the Milky Way's central black hole. If confirmed, this cosmic explosion would be one of the nearest ever found to our galaxy's heart.
NASA's newest space telescope has revealed stunning details of a supernova explosion that lit up Earth's skies two millennia ago. The discovery helps scientists understand why this ancient cosmic event expanded faster than expected.
Astronomers discovered a rare supernova from 10 billion years ago whose light was bent into multiple images by a galaxy's gravity, creating a cosmic time machine that could solve one of science's biggest mysteries. This discovery might finally explain dark energy, the mysterious force pushing our universe to expand faster and faster.
Gravitational wave data reveals proof of rare supernovae so powerful they completely vaporize stars without leaving black holes behind. The discovery helps explain a mysterious gap in black hole sizes across the cosmos.
The James Webb Space Telescope captured light from a supernova that exploded when the universe was just 5% of its current age, shattering the previous distance record by over a billion years. The discovery reveals that ancient stars died in remarkably similar ways to stars today.
Scientists discovered a massive star explosion from just 1 billion years after the Big Bang, offering a rare glimpse into how the earliest stars lived and died. The supernova, nicknamed Eos after the goddess of dawn, could help explain where the building blocks of life first came from.
Scientists just unveiled a breathtaking new look at a 2,000-year-old stellar explosion, combining cutting-edge space technology to reveal secrets of the universe. The collaborative effort between NASA and European telescopes shows how international teamwork is unlocking cosmic mysteries.
For the first time, NASA's Webb Telescope identified a star before it exploded, solving a decades-old mystery about missing supergiants. The discovery could explain why the universe's most massive dying stars have been so hard to find.
When Danish astronomer Tycho Brahe spotted a "new star" in 1572, he didn't just witness a supernova—he sparked the scientific revolution that transformed how humanity understands the universe. As AI promises another scientific revolution, this cosmic explosion reminds us how far observation and measurement have brought us.
Astronomers discovered what could be a supernova remnant closer to our galaxy's central black hole than almost any other stellar explosion ever found. This cosmic discovery reveals how dying stars create the building blocks for future planets and life.
NASA's James Webb Space Telescope just cracked a cosmic cold case 40 million years in the making by spotting the dusty red supergiant that exploded into supernova 2025pht. The discovery explains why some of the universe's most massive stars have been hiding in plain sight.
Scientists finally discovered what powers the brightest stellar explosions ever seen: ultra-magnetic newborn stars spinning hundreds of times per second. The breakthrough came after NASA's Fermi telescope detected gamma rays from a supernova 440 million light-years away.
Astronomers just caught the first-ever birth of a magnetar, one of the most magnetic objects in the universe, solving a mystery that's puzzled scientists for two decades. The discovery confirms that these cosmic powerhouses form during ultra-bright supernova explosions.
For the first time in nearly 20 years of searching, scientists have definitively detected gamma rays from a rare superluminous supernova, solving a cosmic mystery about what powers these exceptionally bright stellar explosions. The culprit: a newborn magnetar with the strongest magnetic field in the universe.
Scientists discovered radioactive stardust from an ancient supernova trapped in Antarctic ice, offering a cosmic time capsule into our solar system's journey through space. The finding helps explain how Earth collects debris from stellar explosions as we travel through interstellar clouds.
Astronomers captured radio signals from an exploding star for the first time, revealing what happened in its final decade of life. The discovery gives scientists a powerful new tool to study how massive stars die across the universe.
Astronomers just witnessed something no one has ever seen before: the birth of a magnetar, one of the universe's most extreme objects. The discovery proves Einstein was right about space-time and reveals how the brightest explosions in the cosmos actually work.
NASA's Webb telescope just proved why aging stars seem to vanish before they explode. The answer hiding in 40 million year old light could rewrite what we know about dying stars.
