Astronomers have identified a peculiar radio transient in the Milky Way that has remained active for more than two decades, defying the behavior expected of known classes of galactic radio sources. The paper posted to the ...
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitational waves (i.e., ripples in spacetime) that ...
A new study suggests that the young stars orbiting the Milky Way's central black hole may have a surprisingly ordinary origin. But the black hole's influence may be what makes their origin look more exotic than it really ...
For years, scientists have relied primarily on radio imaging from techniques like very long baseline interferometry (VLBI) to study jets from the active galactic nuclei of supermassive black holes. This allows for the detection ...
Astronomers have taken one of the deepest looks yet at Cloud-9, a candidate "dark galaxy," and found no trace of stars. The paper outlining this discovery was posted to the arXiv preprint server on Aug. 21.
Astronomers have found the first direct evidence that a wandering black hole can feed itself by dragging gas along in its wake as it moves through its galaxy. It's the first direct evidence of an accretion channel long predicted ...
A new study finds that two early-universe objects thought to be faint quasars are actually extraordinarily luminous galaxies powered by bursts of star formation. James Webb Space Telescope observations of the galaxies, seen ...
Astronomers have detected extreme, never-before-seen behavior from a rare kind of pulsar and stumbled on a surprising link to one of astronomy's biggest current mysteries. Using 174 hours of radio observations, researchers ...
A new study of nine nearby galaxies has shown that actively growing supermassive black holes may contribute to, rather than prevent, star formation in their host galaxies.

Every second, particles zip through your body at nearly the speed of light. They rain down from a storm high in the sky, where cosmic rays, a powerful type of interstellar matter, constantly strike atoms in Earth's atmosphere. ...
