One of the first black holes ever imaged is even stranger than we thought, new images of its dramatically changing environment reveal. The object, known as M87*, has experienced unexpected changes in its magnetic fields that are showing up in polarized light — meaning, light waves that are orientated in the same way (such as vertically, or horizontally). Astronomers are …

Here’s what you’ll learn when you read this story: Black holes usually form from stars that burn out and collapse in on themselves, but that cannot explain the red spark of light that could be a supermassive black hole. QSO1, the object in question, shares several features with supermassive black holes that live in galaxies, but it has no galaxy …

Stellar black holes form from the collapse of massive stars at the end of their lives, typically weighing 3 to 50 times the mass of the sun. When a star runs out of fuel, it explodes in a supernova, leaving behind a region so dense that nothing can escape, not even light. Primordial black holes, by contrast, are theoretical objects …

There could be a 90 percent chance that in the next decade, astronomers will spot a deep space explosion that confirms several long-standing theories about black holes – and which releases a complete collection of every particle in existence, known and unknown. That’s according to a new study from physicists at the University of Massachusetts Amherst (UMass Amherst), which proposes …

The Event Horizon Telescope (EHT) has captured stunning, newly revealed images of the supermassive black hole that lies at the heart of the galaxy M87. The EHT made this black hole, known as M87*, famous in April 2019 when it was revealed as the first black hole ever imaged by humanity. These images of M87*, located around 55 million light-years …

Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had a beginning, a subatomic point called a singularity. This point of intense heat and density rapidly ballooned outward during the big bang. And second, the …

Scientists have measured the recoil velocity from a cataclysmic collision between two black holes for the very first time. Gravitational waves are ripples in space-time first proposed to exist by Albert Einstein, and detected for the first time in 2015. Another first came in 2019, when scientists picked up a gravitational wave signal resulting from a violent merger between vastly …

New research suggests that “little red dots” seen in the early universe may actually be a new class of cosmic object: black hole stars. If this theory is correct, it could explain how black holes managed to grow to supermassive sizes before the universe was even 1 billion years old. Little red dots are one of the most curious celestial …
