'BBQ sauce' phase may link little red dots to quasars

Everyone knows that finding the right sauce recipe can make or break a barbecue, but now astronomers are using BBQSORS (pronounced "barbecue sauce") as part of the recipe to explain quasars, some of the brightest objects ...

Organized microbial guilds keep Earth's underground biosphere running, research reveals

By studying life deep inside a former gold mine, a Northwestern University-led team of scientists has uncovered evidence that Earth's hidden biosphere operates less like a random collection of microbes and more like an organized ...

Astronomers uncover statistical evidence for recoiling supermassive black holes

Galactic collisions are events of breathtaking proportions. The supermassive black holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, ...

Violating the 3rd law of black hole mechanics in vacuum gravity

Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts ...

Are JWST's early, overmassive black holes just normal-range outliers?

Ever since the JWST revealed a population of SMBH in the early universe that were overmassive, scientists have been working hard to explain them. These black holes existed when the universe was only about 2 billion years ...

How heavy can a neutron star get?

The physics of neutron stars are almost too fantastic to believe: something the weight of two suns compacted to a sphere the size of a city. Each teaspoon of its material would weigh billions of tons. If you've done any reading ...

Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy

Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study ...
