Astrophysics

X-ray data gathered by the Chandra telescope from the center of M31, highlighting the four nuclear sources — S1, SSS, N1, and P2. P2 corresponds to the position of the supermassive black hole at the center of the Andromeda galaxy.

When a Black Hole Winks at You

An artistic representation of what a giant cosmic jet the size of the distance between the Milky Way and Andromeda could look like (image for illustrative purposes only).

Cosmic Monsters in Plain Sight: Massive Radio Galaxies May Be More Common Than We Thought

A star and a black hole orbit each other closely: mass from the star is captured by the black hole. As a consequence of this, a pair of jets launch away from the black hole.

Tiny Black Holes Pack a Cosmic Punch: Scientists Spot New Particle Accelerators in Space

Extremely precise measurements of the distance between the Earth and the Coma cluster of galaxies provide new evidence for the Universe’s faster-than-expected rate of expansion.

New Distance Measurements Intensify Mystery of Universe’s Expansion Rate

The massive, yet invisible halo of dark matter of a galaxy cluster works as a "macrolens,", while lone, unbound stars drifting through the cluster act as additional "microlenses, multiplying the factor of magnification.

Webb Telescope Discovers Over 40 Ancient Stars in Distant “Dragon Arc” Galaxy

AI-generated representation of an accreting supermassive black hole, surrounded by gas spiraling toward it along the equatorial plane.

Study Reveals How Early Universe’s Giant Black Holes Grew So Quickly

A gravitational atom. Just as electrons can orbit around the nucleus of an atom, a cloud of previously undiscovered ultralight particles can orbit around pairs of black holes.

Black Hole Mergers Could Reveal Elusive Ultralight Particles

An artist’s illustration depicts a primordial black hole (at left) flying past, and briefly “wobbling” the orbit of Mars (at right), with the sun in the background. MIT scientists say such a wobble could be detectable by today’s instruments. Credits:Credit: Image by Benjamin Lehmann, using SpaceEngine @ Cosmographic Software LLC.

Mars’ Wobble Could Reveal Dark Matter, MIT Study Suggests

Early dark energy could have triggered the formation of numerous bright galaxies, very early in the universe, a new study finds. The mysterious unknown force could have caused early seeds of galaxies (depicted at left) to sprout many more bright galaxies (at right) than theory predicts. Credits:Image: Josh Borrow/Thesan Team

Early dark energy could resolve cosmology’s two biggest puzzles

New AI Distinguishes Dark Matter from Cosmic Interference

Side-by-side simulated images of M87* show the improvement in clarity and resolution from 230 GHz to 345 GHz. These improvements are allowing scientists to measure the size and shape of black holes more precisely.

Event horizon telescope makes highest-resolution black hole detections from Earth

SETI Institute starts first low frequency search for alien technology in distant galaxies

SETI Institute Expands Search for Alien Tech to Distant Galaxies

An infographic showcasing the methodology behind the Simulation-Based Inference of Galaxies (SimBIG) project.

AI Unlocks Hidden Data to Refine Universe’s ‘Settings’

Neutrinos of different “flavor” quantum states (shown by colors) are entangled through interactions. In dense neutrino environments like core-collapse supernovae, this leads neutrinos of different flavors to equilibrate to similar energy distributions.
