For decades, scientists have been observing how galaxies spin and move throughout the universe. Gravity acts on stars and galaxies, in the same way it keeps you from floating off into space. Heavier ...

Scientists believe that when galaxies collide and merge, the supermassive black holes at their centers should eventually pair ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

Astronomers have observed a rare event in the solar system, a comet slowing its rotation and then spinning in the opposite ...

First its rotation slowed between March and May 2017, taking 46 hours to complete a spin where it had once taken only 20 hours. This occurred as the comet neared its closest point to the sun, roughly ...

Researchers at Oxford University and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) are ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

As next-generation telescopes map this outer frontier, astronomers are bracing for discoveries that could reveal hidden planets, strange structures, and clues to the solar system’s chaotic youth.

Astronomers at the University of Washington recently discovered a record-breaking asteroid using early images from the new Vera C. Rubin Observatory in Chile, Azernews reports, citing foreign media.
