Astronomers discover a 'lost world' of black hole mergers: 'It's the astronomical equivalent of uncovering an ancient civilization'

Astronomers discover a 'lost world' of black hole mergers: 'It's the astronomical equivalent of uncovering an ancient civilization' "Now, we have growing evidence that there are ways that the universe creates merging black holes in addition to those that come from massive binary stars." Astronomers have struck "black gold" — a treasure trove of black hole mergers. And the discovery was made by analyzing ripples in the very fabric of space and time, or spacetime, called gravitational waves.

Hidden supermassive black hole pairs may finally have a visible signal

Hidden supermassive black hole pairs may finally have a visible signal - Date: - June 5, 2026 - Source: - University of Oxford - Summary: - Scientists have proposed a new method for finding tightly bound supermassive black hole pairs by searching for stars that flash repeatedly as their light is magnified by the black holes’ gravity. The timing and brightness of these bursts could provide a unique fingerprint of black holes slowly spiraling toward a future collision. Astronomers from the...

Astronomers discover the earliest known flickering quasar

Astronomers discover the earliest known flickering quasar Gaby Clark Scientific Editor Andrew Zinin Lead Editor A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and falls onto a black hole, it lights up its vicinity, radiating a huge amount of energy.

Scientists think they solved the mystery of the Amaterasu particle

Scientists think they solved the mystery of the Amaterasu particle - Date: - June 9, 2026 - Source: - Penn State - Summary: - The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better able to retain their energy while traveling through space. This idea could help explain how these rare particles reach Earth and provide new clues about the powerful cosmic...

Hundreds of new moons are revealing our solar system's violent history

In the far reaches of the solar system, the planetary neighbourhood seems quiet. Beyond Jupiter, the sun is no longer a blazing disc, but a cold, white lamp. The planets are separated by gulfs of darkness.

Amplified Arctic iceberg traffic reshapes benthic biodiversity

Abstract The Arctic is undergoing rapid warming, resulting in retreating sea ice and glaciers1, yet how cryospheric changes propagate into the deep ocean remains poorly understood2. Here we identify a climate-driven mechanism linking accelerating glacier disintegration to an increase in deep-sea hard-bottom habitats far beyond calving fronts. Seafloor observations in Fram Strait show a localized increase in the density and patchiness of dropstones delivered by debris-laden icebergs.

Tabletop experiment helps reconcile fundamental physics

Tabletop experiment helps reconcile fundamental physics Gaby Clark Scientific Editor Andrew Zinin Lead Editor Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and her colleagues show how a tabletop experiment can bring together two bedrock physics theories that have never been fully reconciled. More than a century ago, Albert Einstein gave us the theory of general relativity, describing gravity in relation to space and...

2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints

2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints Our solar system may have hosted up to six giant planets in its first hundred million years, a new study suggests. The findings paint a more crowded picture of the early outer solar system than previously thought. Something doesn’t quite add up about the orbits of our solar system’s eight planets and their hundreds of moons, a new study hints.

Magnetic fields may be the secret behind binary star formation

Magnetic fields may be the secret behind binary star formation - Date: - June 5, 2026 - Source: - National Institutes of Natural Sciences - Summary: - Scientists have uncovered a surprising force that may help explain how binary star systems form so quickly. New supercomputer simulations show that magnetic fields surrounding newborn stars can act like a cosmic brake, stripping away angular momentum and allowing two still-forming protostars to spiral closer together instead of drifting apart....

Trouble near the Milky Way: The Large Magellanic Cloud is ripping its smaller neighbor galaxy apart

Trouble near the Milky Way: The Large Magellanic Cloud is ripping its smaller neighbor galaxy apart In the gravitational tug of war between the dwarf galaxy siblings, it's the Small Magellanic Cloud that's losing. The Small Magellanic Cloud seems to be coming undone at the gravitational hands of its sibling galaxy, the Large Magellanic Cloud, which has been found to be unwrapping its little brother's stars. The Small and Large Magellanic Clouds (SMC and LMC for short) are two dwarf irregular...
