Euclid discovers the most ancient quasars in the universe

The European Space Agency's Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed in cosmic history. They shone with the light of a tr

Black women academics in my study said their main allies were white men: What this reveals

Universities have a role in challenging the status quo on issues such as gender, race, nationality and sexuality. But all too often, they replicate societal inequalities.

Birdwatch: A yellowhammer cheer squad on my cycle around Suffolk

That characteristic song was an unexpected delight alongside the chiffchaffs, blackcaps and whitethroats tooWith hindsight, the late June heatwave was not the ideal time for my (very) old schoolmates and me to be cycling around Suffolk. Yet, despite the searing heat and the laten

JWST's 'overmassive' early black holes may not be so massive after all

Astronomers studying a population of unusually X-ray-silent and overmassive black holes discovered by the James Webb Space Telescope have found that they may not be as massive as they appear. The new paper, outlining a plausible scenario that would produce such black holes, was p

Black hole collisions may follow entropy law, offering simpler remnant predictions

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significantly distorts the universe around it. It emits gravitational waves—ripples in the fabric of spacetime—

These ancient quasars shouldn't exist so soon after the Big Bang

Astronomers have uncovered 31 of the oldest known quasars, including the two earliest ever detected, shining from a time when the universe was only about 670 million years old. Powered by supermassive black holes billions of times the Sun’s mass, these incredibly bright objects c

Understanding anti-blackness at Hispanic-serving research universities

At Hispanic-Serving Institutions (HSIs), conversations about diversity often center on supporting Hispanic/Latine students. New research from scholars at University of New Mexico highlights an important and sometimes overlooked issue--the experiences of Black students at these un

Saturday Citations: Blue zone longevity; soft tissue find predates dinosaurs; black hole c

This week, researchers reported finding nanoplastics in Antarctic soils for the first time, suggesting they were delivered via long-range atmospheric transport. A study associates the use of hormonal birth control with the risk of brain tumors. And researchers developed a new dru

Synthetic rotation brings black hole energy theory into lab, amplifying waves

More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole spinning at extreme speeds. He proposed that a particle entering its ergosphere—a region of space dragged around by a rotating black hole—could split into tw

The South African trailblazers seeking to change how wildlife documentaries are made

National Geographic explorers create dive lab after finding too few black film-makers telling African wildlife storiesWhen Pragna Parsotam-Kok and Noel Kok made a wildlife series for South African TV in 2015, they were struck by how challenging it was to access animals to film an

Physicists recreate black hole energy extraction in the lab

Researchers have recreated the physics of extracting energy from a spinning black hole using a stationary device that produces synthetic ultrafast rotation. The achievement transforms a long-standing theoretical idea into a practical experiment and could inspire new advances in o

Gravitational waves reveal hidden populations within black hole mergers

Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady stream of signals from colliding black holes, building a catalog that now numbers in the hundreds. Yet despite this wealth of data, a fundamental question ha
