If dark matter is made of ultralight particles that ripple like waves, those ripples should shift the multiple images of a distant quasar. The simulations matched a real lensed quasar better than standard models.
PSR J1227-4853 spins 592 times a second. Indian astronomers found 235 giant pulses in 174 hours of observation, some 10,000 times brighter than the star's ordinary signal.
PSR J1637-4642 was quiet through ten years of monitoring at Australia's Murriyang telescope. Fifteen and a half years of data now show three sudden spin-ups, and the biggest of them jumped the star's rotation by 2.7 parts per million.
RBH-1 left a trail of newborn stars 202,000 light-years long. A Santa Barbara team worked backward to the merger that threw it out, about 70 million years ago.
When a supermassive black hole switches its jets off, the leftover lobes were thought to glow for a long, slow stretch. A survey with MeerKAT found the afterlife is short — and earlier searches were looking for the wrong thing.

ALMA resolved a magnetic field coiled around the gas streaming off a protostar 960 light-years away. It is a few thousandths of a gauss — weaker than a fridge magnet, and strong enough to shape a star.
Astronomers measured the gravitational redshift of SDSS J0608−0059 and found it sits on the wrong mass-radius curve for an ordinary white dwarf — evidence it came from a single massive star, not a merger.
The Einstein Probe caught the faintest X-ray shock breakout ever seen from this class of supernova. Two independent teams found no jet, no burst, and a 20-solar-mass Wolf-Rayet star that should have made both.
A Flatiron Institute simulation of the galaxy’s entire history finds that about 91% of stellar-mass black holes drift alone, and roughly 3% were kicked out of the galaxy altogether.
The Jellyfish Nebula turns out to have a sibling. A Stanford-led team used 16 years of gamma-ray data to show the two remnants came from a single binary system — a pairing never seen before.

A team led by SUNY Poly and the Kavli IPMU finds that a primordial black hole passing through a white dwarf could tidally heat it into a thermonuclear runaway — and that the resulting explosions would leave a distinctive chemical signature already visible in the Milky Way.
Researchers at 25 institutions showed the mysterious 'low-energy enhancement' comes from magnetic transitions inside the nucleus — a result that changes how fast stars are calculated to build heavy elements.

By combining Event Horizon Telescope and Global Millimeter VLBI Array images at two wavelengths, a Shanghai-led team produced the first spatially resolved spectral map of a black hole's shadow.
Sifting through two decades of Hubble images, a University of Utah team spotted a star being tugged by an invisible companion — the first of thousands of black holes thought to be hiding in the giant cluster.
A Caltech astrophysicist calculates that lopsided eruptions from bloated, dying sun-like stars act like thousands of tiny rocket thrusts, nudging the stars to speeds of about a kilometer per second.
By jolting a mix of simple gases with 10,000 volts, a University of Sydney researcher brewed synthetic cosmic dust laced with the carbon-based molecules that form the building blocks of living things.
A model proposing that dark matter is made of at least two kinds of particles — a heavier one that sinks toward galactic centers and a lighter one that drifts outward — could resolve puzzles that have frustrated cosmologists for years.
A CUNY team built a spinning system out of engineered metamaterials that amplifies passing waves — reproducing the half-century-old Penrose-Zel'dovich process once thought possible only around a rotating black hole.
A neural network called RHINE lets physicists simulate the violent nuclear furnace of a neutron-star merger in a fraction of the time, sharpening the story of where the heaviest elements come from.

A single 10-month observing run added 161 new detections, nearly doubling the record — and delivered the sharpest gravitational-wave signal ever recorded, along with hints that some black holes are built from earlier black holes.
The most detailed spectrum yet of one of these ancient objects strongly favors a black hole cloaked in hot gas over a galaxy full of stars — evidence, researchers say, of heavy black-hole seeds being born in real time.
