Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion ...
We have known for a while that the Milky Way is full of homeless worlds. Rogue planets, free-floating planets—call them what you like—but they are planets formed in orderly systems around ordinary stars and then thrown out, ...

For decades, astronomers lumped brown dwarfs into a single category defined by mass alone—too big to be classified as planets but too small to become stars. However, this definition ignores the two very different mechanisms ...
By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by ...
A popular myth about black holes is that they act like giant cosmic vacuum cleaners, sucking in everything around them. But Wladimir Lyra's research found a new mechanism around supermassive black holes that is more like ...

Gravitational waves are tiny ripples in the fabric of spacetime that are produced when massive objects in the cosmos accelerate or collide. By detecting these waves, astrophysicists can study various cosmic events, including ...
An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers ...

Astronomers have built the first three-dimensional map of gas temperature in the space surrounding our solar system, revealing a far messier and more dynamic picture than current models predict. The study was submitted to ...
Data released by the Sloan Digital Sky Survey (SDSS) marks a landmark expansion in the study of accreting supermassive black holes (SMBHs). As part of the fifth generation of the survey (SDSS-V), the Black Hole Mapper (BHM) ...
